How Often Are Will Contests Successful? (w/Examples) + FAQs

Will contests rarely succeed. The overall success rate at trial hovers around just 1%, and even with the most generous estimates, fewer than 10% of contested wills are overturned. That said, the real picture is more complicated than a single number suggests.

Under state probate codes across the country, a will carries a legal presumption of validity once it is admitted to probate. The person who challenges the will — called the “contestant” — carries the burden of proving that something went wrong. That burden, combined with tight filing deadlines and high litigation costs, makes will contests one of the hardest types of lawsuits to win. Research from the Nevada Law Journal shows that only about 3% of all wills filed in the United States even face a formal dispute.

Why the Success Rate Is Misleading

The 1% to 10% success rate you see quoted online only tells part of the story. That number reflects cases that go all the way to trial and result in the will being thrown out. What it does not capture is the large number of will contests that end in a private settlement before trial.

Roughly 90% to 97% of litigated will contest cases are resolved through settlement rather than a courtroom verdict. A settlement might give the contestant a portion of the estate, a specific asset, or a cash payout — even though the will itself is never formally invalidated. For many families, a settlement is a successful outcome because it avoids the cost and emotional toll of a full trial.

In California, for example, fewer than a third of will contests that reach a decision are successful. But that figure does not include cases where the parties reached a deal behind closed doors. The strength of your evidence, the skill of your attorney, and the willingness of the other side to negotiate all affect your real odds far more than a national statistic.

Legal Grounds for Contesting a Will

You cannot contest a will simply because you are unhappy with what you received. Courts require you to prove a legally recognized reason — known as “grounds” — that the will is not valid. The most common grounds fall into five categories.

Lack of Testamentary Capacity

Testamentary capacity is the legal term for having a sound enough mind to create a valid will. Under laws in nearly every state, the person making the will (the “testator”) must understand three things at the moment they sign:

• The nature of what they are doing (making a will)
• The extent and value of their property
• Who their natural heirs are and their relationships with those heirs

The mental bar for testamentary capacity is actually lower than the bar for signing a contract. A person with mild cognitive issues can still have the legal capacity to make a will. But if the testator had severe dementia, was on heavy medication, or lacked awareness of their surroundings at the time of signing, a court may find they lacked capacity.

Courts give a rebuttable presumption that the testator had capacity. This means you are assumed capable until proven otherwise. The contestant must present enough evidence to overcome that presumption — medical records, witness testimony, expert opinions — to show the testator did not understand what they were signing.

Undue Influence

A will must reflect the testator’s own wishes. Undue influence occurs when someone exerts so much pressure, manipulation, or control over the testator that the resulting will reflects the influencer’s desires rather than the testator’s.

Simply persuading someone to change their will is not undue influence. The line gets crossed when the influence is so strong that the testator could not resist it. Courts look for three elements: motive, opportunity, and actual exercise of the influence.

Evidence of undue influence is almost always circumstantial because this kind of manipulation happens behind closed doors. Contestants often present proof that the influencer controlled the testator’s housing, finances, healthcare, or access to other family members. A common scenario involves a caretaker who isolates an elderly person and then guides them to sign a new will leaving the caretaker a large portion of the estate.

Fraud and Forgery

A will can be challenged if it was created through deception or if the document itself is forged. Fraud in the will context takes two forms. Fraud in the inducement means someone tricked the testator into signing — for example, lying that a child abandoned them so they would cut that child out of the will. Fraud in the execution means the testator was tricked about the document itself, such as being told they were signing a power of attorney when they were actually signing a new will.

Forgery is a more straightforward claim. If the testator’s signature was faked or if the entire will was fabricated by someone else, the will is void from the start. Courts may appoint independent handwriting experts or document analysts to review the signature. When clear proof of forgery exists, courts reject the forged will and distribute assets under either a prior valid will or the state’s intestacy laws.

Improper Execution

Even a will that reflects the testator’s true wishes can be thrown out if it was not signed the right way. Each state sets its own rules for proper execution, but the most common requirements include:

• The testator must sign the will at the end of the document
• Two witnesses must watch the testator sign (or hear the testator acknowledge the signature)
• The testator must declare the document to be their will
• The witnesses must sign the will at the testator’s request

When an attorney supervises the will signing, courts apply a presumption of due execution — meaning it is assumed the signing followed all the rules. Wills prepared from online DIY services without attorney supervision do not get this benefit, which makes them easier targets for a contest.

Revocation

A will can also be challenged on the basis that it was revoked — meaning the testator canceled it before they died. Revocation can happen through a physical act (tearing up or burning the will) or through the creation of a new will that explicitly revokes the old one. If someone tries to probate a will that has been revoked, any interested party can challenge its admission.

Who Has the Right to Contest a Will?

Not everyone can challenge a will. You need standing, which means you must be a person with a direct financial stake in the outcome. Under most state laws, people with standing include:

• Beneficiaries named in the current will
• Beneficiaries named in a previous version of the will
• Legal heirs who would inherit under the state’s intestacy laws if there were no will (spouses, children, parents, siblings)
• In some states, unpaid creditors of the deceased

If you are a friend, neighbor, or distant acquaintance with no financial connection to the estate, you have no legal right to file a contest — no matter how suspicious the will looks.

Deadlines for Contesting a Will by State

One of the biggest threats to a will contest is the filing deadline. Every state imposes a strict statute of limitations that ranges from as little as three months to as long as two years. Miss the deadline, and you lose your right to contest the will — regardless of how strong your case is.

The clock typically starts ticking at probate, not at the date of death. This distinction matters because probate can begin quickly — sometimes within days. In Florida, the three-month window is so strict that if you miss it, your objections are “forever barred,” with only a narrow exception for cases where the personal representative misstated the deadline.

The Will Contest Process: Step by Step

Filing a will contest follows a structured legal path, though the exact steps vary by state. Here is a general breakdown of what to expect.

Step 1: Determine Standing. Before anything else, confirm that you qualify as an interested party with standing to challenge the will. If you would not gain or lose money based on the will’s validity, you cannot file.

Step 2: Identify Legal Grounds. Gather evidence that supports at least one recognized legal ground for the contest — lack of capacity, undue influence, fraud, improper execution, or revocation. A general suspicion or disagreement with the will’s terms is not enough.

Step 3: File a Petition. Submit a formal written petition or pleading to the probate court handling the estate. The petition must specify the grounds for the contest with supporting facts. In some states and counties, filing a bond may be required to cover the estate’s costs if your challenge fails.

Step 4: Serve the Parties. The petition must be served on all interested parties, including the executor, named beneficiaries, and other heirs. This gives everyone the chance to respond and defend the will.

Step 5: Discovery and Evidence Gathering. Both sides collect evidence. This phase often includes gathering medical records, financial records, witness statements, prior versions of the will, and expert opinions. Discovery can be the most time-consuming and expensive part of the process.

Step 6: Mediation or Settlement. Many courts encourage or require mediation before trial. Given that the vast majority of will contests settle, this stage is where most cases end. Settlement allows both sides to avoid the uncertainty and expense of a trial.

Step 7: Trial. If no settlement is reached, the case goes to trial. A judge (or in some states, a jury) hears the evidence, and the contestant must prove their claims by a preponderance of the evidence — meaning it is more likely than not that the will is invalid.

Real-World Examples of Will Contests

Will contests are not abstract legal theories. They happen to real families — and some of the most dramatic examples involve famous names.

Aretha Franklin: The Will Under the Couch Cushion

When the Queen of Soul died in 2018, her family initially believed she had no will. Her estate, worth about $6 million, entered probate. But months later, a family member searching the home found not one, but two handwritten wills — one from 2010 locked in a cabinet, and a four-page document dated 2014 stuffed inside a spiral notebook between couch cushions.

Two of Franklin’s sons supported the 2014 document. A third son wanted the 2010 version to control. The dispute went to a jury trial in July 2023 in Pontiac, Michigan. Michigan is one of the states that recognizes holographic wills — handwritten wills that do not require witness signatures — and the jury concluded that the 2014 document was valid. The 2014 will, signed with Franklin’s name and a smiley face, now governs the distribution of her estate.

Lesson: A will does not have to be typed or prepared by a lawyer. But informal wills invite confusion and family conflict. Proper estate planning with an attorney could have prevented this five-year legal battle entirely.

Anna Nicole Smith: A 15-Year Legal War

Anna Nicole Smith married 89-year-old billionaire J. Howard Marshall II in 1994. Marshall died in 1995, and his estate — estimated at up to $1.6 billion — passed through a trust to his youngest son, E. Pierce Marshall. Smith claimed her late husband had promised to create a separate trust for her, but his son had interfered with that plan.

The legal fight crossed state lines and lasted 15 years, producing two trips to the U.S. Supreme Court. In Marshall v. Marshall (2006), the Supreme Court unanimously ruled that federal courts had jurisdiction to hear Smith’s claims — a landmark decision that redefined the boundaries of the “probate exception” to federal jurisdiction.

Both Anna Nicole Smith and Pierce Marshall died before the case ended. The Ninth Circuit ultimately rejected Smith’s estate’s claims, but the case produced a second Supreme Court ruling in Stern v. Marshall (2011) that limited the power of bankruptcy courts to issue final rulings on state law counterclaims.

Lesson: Trusts and wills that are not updated after major life events like marriage create massive openings for litigation. Clear, updated estate documents save families from decades of legal warfare.

Leona Helmsley: $12 Million for a Dog

New York hotel magnate Leona Helmsley, known as the “Queen of Mean,” died in 2007. Her will left $12 million in a trust for her Maltese dog, Trouble — while disinheriting two of her grandchildren entirely.

The disinherited grandchildren challenged the will. A Manhattan Surrogate Court judge found that Helmsley was mentally unfit when she signed the will. The court slashed Trouble’s trust from $12 million to $2 million and redirected $6 million to the disinherited grandchildren, with the remaining $4 million going to Helmsley’s charitable trust.

Lesson: Courts can — and will — intervene when provisions seem unreasonable. Leaving excessive amounts to a pet while disinheriting close family members invites successful challenges, especially when mental capacity is questionable.

Huguette Clark: The $300 Million Recluse

Huguette Clark, the daughter of copper baron Senator William A. Clark, died in 2011 at age 104. She had spent the last 20 years of her life in a New York City hospital room with the shades closed, watching cartoons and playing with dolls. Her estate was worth over $300 million.

Clark signed two wills within six weeks of each other in 2005. The first will left most of the estate to family members. The second will left her family nothing, instead directing assets to a foundation for the arts, her nurse (who had already received $31 million in gifts during Clark’s lifetime), her lawyer, and her accountant.

Clark’s 20 distant relatives contested the second will, alleging undue influence, lack of capacity, and fraud. The case settled on the eve of trial, with the relatives receiving a $34.5 million settlement. Clark’s nurse, Hadassah Peri, agreed to return $5 million to the estate and gave up rights to millions more.

Lesson: When a testator’s attorney, accountant, and daily caretaker are all named as beneficiaries, courts and juries take undue influence allegations very seriously. Professionals involved in a person’s care should generally not benefit from the will they helped create.

Michael Jackson: Siblings vs. the Executors

Michael Jackson died in 2009, leaving behind an estate worth an estimated $500 million. His will named attorney John Branca and music executive John McClain as co-executors. Several of Jackson’s siblings, who were left out of the will, signed a letter calling the will a fake and demanded the executors resign. One signatory, Jermaine Jackson, later retracted his signature.

The contest was settled out of court, with Branca and McClain remaining as co-executors. The Jackson estate has since grown to be worth billions.

No-Contest Clauses: The “Scare Tactic” in Wills

Some wills include a no-contest clause — also called an in terrorem clause — that threatens to disinherit any beneficiary who challenges the will. The idea is simple: if you contest the will and lose, you forfeit whatever you would have received.

These clauses are designed to discourage frivolous challenges and keep the estate out of prolonged litigation. But their enforceability varies widely from state to state.

In California, simply requesting a trust accounting, petitioning to remove a trustee, or filing an elder abuse claim generally will not trigger a no-contest clause. The state’s probable cause exception also protects contestants who had a reasonable basis for filing.

In Florida, no-contest clauses carry zero legal weight. This means a Florida beneficiary can challenge a will without any risk of losing their inheritance under the clause.

How Much Does It Cost to Contest a Will?

Will contests are expensive. Attorney fees alone can easily reach $5,000 to $10,000 at a minimum, and complex cases involving expert witnesses, extensive discovery, and trial preparation can cost tens of thousands — or even hundreds of thousands — of dollars.

In most cases, the person contesting the will pays their own attorney fees upfront. Probate litigation attorneys typically work on a retainer basis, meaning you pay a lump sum upfront and the attorney deducts fees as work is performed. Few attorneys will take a will contest case on contingency — where the lawyer only gets paid if you win — because of how difficult these cases are.

However, some states allow the prevailing party to recover attorney fees from the estate. In Wisconsin, for example, courts have ruled that nonfamily beneficiaries who prevail in a contested matter are entitled to have the estate cover their fees. In New Jersey, courts have held that both sides in a will dispute may receive fee awards from the estate, except in “weak or meretricious” cases.

How Settlements Work in Will Contests

Since the vast majority of will contests end in settlement rather than a courtroom verdict, understanding how settlements work is just as important as understanding the trial process.

A settlement in a will contest is a private agreement between the parties that resolves the dispute without the court making a final ruling on whether the will is valid. Settlements can take many forms. In some cases, the contestant receives a lump-sum cash payment from the estate. In others, specific assets — a house, a bank account, personal items — are transferred to the contestant outside the terms of the original will.

Settlements happen for practical reasons. The executor and the beneficiaries defending the will know that a trial is expensive, unpredictable, and public. Even if they believe the will is valid, they may prefer to pay a smaller amount to make the contest go away rather than risk a judge or jury overturning the entire document. For the contestant, a settlement offers a guaranteed outcome — money in hand — rather than the gamble of a trial where the odds are already stacked against them.

The Huguette Clark case is a prime example. Clark’s distant relatives could not prove with certainty that the 104-year-old heiress lacked capacity, but the risk of that finding was enough to push the parties toward a $34.5 million settlement on the eve of trial. Clark’s nurse also agreed to return $5 million to the estate, which suggests even the defense recognized the optics of a nurse receiving $31 million in lifetime gifts from her patient were damaging.

How Undue Influence Plays Out in Real Families

Undue influence is the most commonly litigated ground in will contests, and it does not just happen in celebrity estates. Here is how a typical scenario unfolds in everyday families.

Imagine a woman named Linda, age 82, who has three adult children. Linda’s health declines, and her youngest son, Mark, moves in to care for her. Over the next two years, Mark gradually restricts Linda’s contact with her other children, screens her phone calls, and attends every meeting with her attorney. Linda signs a new will leaving everything to Mark, cutting out her other two children entirely.

After Linda dies, the other children discover the new will and file a contest based on undue influence. Their evidence includes testimony from neighbors who saw Mark turning away visitors, phone records showing calls from the other children went unanswered, and a statement from Linda’s longtime doctor that she had expressed concerns about Mark’s controlling behavior. They also show that the attorney who prepared the new will was recommended by Mark — not Linda.

This type of circumstantial case is exactly what courts examine in undue influence claims. No single piece of evidence proves the case alone, but together they paint a picture of someone whose free will was overridden.

Mistakes to Avoid When Contesting a Will

Will contests fail for predictable reasons. Avoiding these common mistakes can mean the difference between recovering your inheritance and walking away with nothing.

1. Missing the filing deadline. This is the single most common reason will contests are dismissed. Every state has a strict statute of limitations, and once the deadline passes, your case is gone — period. Consult an attorney the moment you learn about the will.

2. Lacking standing. You must prove you have a direct financial interest in the estate. Being angry or hurt is not enough. If you are not a named beneficiary, an heir under intestacy laws, or a beneficiary under a prior will, you cannot file.

3. Insufficient evidence. Courts do not invalidate wills based on suspicion alone. You need concrete evidence — medical records, witness testimony, financial documents, or expert reports — that supports your legal grounds. Weak evidence leads to dismissed cases and wasted money.

4. Ignoring a no-contest clause. If the will contains an in terrorem clause and you are a named beneficiary, filing a contest without legal advice can cost you everything you were set to inherit. Always have an attorney assess the clause’s enforceability in your state before taking action.

5. Going it alone without an attorney. Will contests involve complex procedural rules, evidence standards, and state-specific laws. Self-represented contestants face uphill battles against experienced estate litigation attorneys. An attorney who specializes in will contests can evaluate your case, build your evidence, and protect your rights.

6. Waiting too long to gather evidence. Memories fade. Witnesses move away or die. Medical records become harder to access over time. The longer you wait to begin building your case, the weaker your evidence becomes.

7. Letting emotions drive decisions. Grief, anger, and family conflict are natural after a death. But courts decide will contests based on evidence and law, not feelings. Emotional arguments without legal substance lead to losses.

The Burden of Proof in Will Contests

Understanding who carries the burden of proof — and how heavy that burden is — can help you gauge your chances before you file.

In most states, when a will is submitted for probate, it is presumed to be valid. If the will was signed under attorney supervision, it gets an even stronger protection called the presumption of due execution.

The contestant carries the burden of production, which means they must present enough evidence to make their case. The standard of proof is a “preponderance of the evidence” — you need to show that your claims are more likely true than not. This is a lower bar than the “beyond a reasonable doubt” standard used in criminal cases, but it is still a real hurdle when the will was properly executed and the testator appeared competent.

In some states, the burden shifts in specific circumstances. For example, if a contestant proves a confidential relationship between the beneficiary and testator plus suspicious circumstances, the burden may shift to the will’s proponent to prove the will was genuine. This shift makes it easier for the contestant to succeed.

State-by-State Nuances That Affect Your Case

While every state recognizes the same basic grounds for contesting a will, the details differ in ways that can make or break your case.

California uses a 120-day deadline measured from when the will is admitted to probate. It enforces no-contest clauses in limited situations but protects contestants who act with probable cause. The burden of proof falls on the contestant under a preponderance of the evidence standard.

Florida has one of the most restrictive deadlines in the country — just three months from the Notice of Administration. Florida also makes no-contest clauses completely unenforceable, which means beneficiaries can challenge a will without risking their inheritance. Florida requires two witnesses for a valid will, and the formalities must be strictly followed.

New York gives contestants three months after receiving a citation to file their objections. If you were never properly notified of probate, you may have up to two years. New York enforces no-contest clauses but will not enforce them when a beneficiary questions the eligibility or conduct of a fiduciary, protecting legitimate oversight actions.

Texas requires two witnesses to a valid will and imposes a two-year statute of limitations for will contests, which is one of the longest in the country. Texas courts tend to enforce no-contest clauses strictly, making it risky for Texas beneficiaries to challenge without strong evidence.

Michigan is notable because it recognizes holographic wills — as the Aretha Franklin case demonstrated. A handwritten, signed, and dated will in Michigan does not need witness signatures to be valid. This makes Michigan one of the more flexible states for informal wills, but it also means more opportunities for disputes over authenticity.

These variations are why it is critical to consult a probate attorney in the state where the will is being probated, not just any attorney. What works as a winning strategy in one state may be a losing move in another.

Do’s and Don’ts of Will Contests

Do’s

• Do consult a probate litigation attorney before filing — they can assess whether your case has merit and what it will cost.
• Do act fast — deadlines are short and once missed, they cannot be extended in most states.
• Do gather medical records, financial documents, witness names, and prior versions of the will as early as possible.
• Do consider mediation or settlement — most will contests resolve outside of court, saving time and money.
• Do check for a no-contest clause before filing — especially if you are already a named beneficiary.

Don’ts

• Don’t assume the will is valid just because it looks professional — even attorney-prepared wills can be challenged on grounds like undue influence or fraud.
• Don’t file a contest based on feelings alone — you need specific legal grounds and real evidence.
• Don’t discuss your contest plans publicly or on social media — anything you say can be used against you in court.
• Don’t try to represent yourself — will contests are procedurally complex and self-representation almost always puts you at a disadvantage.
• Don’t ignore the financial reality — litigation costs add up fast, and you should weigh the potential inheritance against the cost to fight for it.

Pros and Cons of Contesting a Will

Pros

• Restoring rightful inheritance. A successful contest can correct a will that was the product of manipulation or incompetence, returning assets to those who should have received them.
• Deterring bad actors. Contesting a will sends a message that fraud, undue influence, and elder abuse will not be tolerated.
• Settlement opportunity. Even if you do not win at trial, the process of filing a contest often leads to a negotiated settlement that gives you a portion of the estate.
• Protecting vulnerable testators. Will contests serve as a check against exploitation of elderly or mentally impaired individuals.
• Validating the correct will. When multiple versions exist (as in Aretha Franklin’s case), a contest ensures the right document controls.

Cons

• High cost. Attorney fees, expert witnesses, and court costs can reach tens of thousands of dollars or more.
• Low success rate. The odds of overturning a will at trial are statistically low.
• Family damage. Will contests often pit siblings, spouses, and children against each other, causing permanent rifts in family relationships.
• Lengthy timeline. Will contests can drag on for months or even years, delaying the distribution of assets to everyone in the estate.
• Risk of losing inheritance. If the will includes a no-contest clause that is enforceable in your state, filing a contest could cause you to lose what you were already set to receive.

FAQs

Can you contest a will after probate is closed?
No. In most states, once probate is finalized and assets are distributed, contesting a will is no longer possible. Some states allow late challenges under narrow exceptions, such as fraud discovery.

Does a no-contest clause prevent all challenges?
No. Many states have a probable cause exception that protects good-faith challenges, and some states like Florida do not enforce these clauses at all.

Can a spouse be disinherited?
No, in most states. Surviving spouses are protected by “elective share” laws that guarantee them a minimum percentage of the estate regardless of what the will says.

Do I need a lawyer to contest a will?
Yes, in practice. While you can technically file on your own, the procedural complexity and evidence requirements make professional representation essential for any realistic chance of success.

Can a will be contested if there is no will?
No. If someone dies without a will (intestate), there is nothing to contest. However, you can dispute the distribution of assets under the state’s intestacy laws.

Is a handwritten will valid?
Yes, in some states. About half of U.S. states recognize holographic wills — handwritten wills that may not require witness signatures — as long as the testator signed and dated them.

How long does a will contest take?
It varies. Simple disputes may resolve in a few months through settlement. Complex cases involving trial can take 6 to 18 months or longer, depending on court schedules and case complexity.

Can an executor contest a will?
Yes. An executor is an interested party and can raise concerns about the will’s validity. However, their fiduciary duty to the estate may create conflicts of interest.

What happens if a will contest is successful?
It depends. The court may reinstate a prior valid will, or if no earlier will exists, distribute assets under the state’s intestacy laws, which follow a set hierarchy of heirs.

Can you contest a will from another state?
Yes, but the contest must be filed in the state where the will is being probated. That state’s laws govern the contest, not the laws of where you live.
