To file a will contest, you submit a formal petition to the probate court handling the deceased person’s estate, within your state’s filing deadline, stating the legal ground for your challenge and the facts that support it. Before you file, three things have to be in place: you must have standing to challenge the will, you must be able to point to a recognized legal defect rather than just an unfair result, and you should have enough evidence to make the claim credible. Miss the deadline, and it almost never matters how strong your case would have been.
Confirm You Have Standing
Not everyone who dislikes a will can challenge it. Courts require standing, meaning a direct financial stake in the outcome. Two groups generally qualify: beneficiaries named in a prior version of the will who were cut out or reduced in the contested version, and legal heirs who would inherit under the state’s default inheritance rules if no valid will existed.
Heirs typically include a surviving spouse, children, and sometimes parents or siblings, depending on state law. Estate creditors may have standing in limited circumstances. The overwhelming majority of contests, though, come from family members who believe the will doesn’t reflect what the deceased actually wanted.
Identify a Legal Ground for the Challenge
Disagreeing with how someone divided their property is not a legal ground. You need a specific flaw in how the will was created, signed, or influenced.
Lack of Testamentary Capacity
The testator must have been mentally competent when they signed. The bar is not high: they needed to understand what property they owned, who their close relatives were, and what the will would do with their assets. Advanced dementia, severe mental illness, or heavy sedation can undermine that threshold. Capacity is evaluated as of the moment of signing, not the weeks around it.
Undue Influence
Undue influence means someone pressured or manipulated the testator into producing a will that reflects the influencer’s wishes rather than the testator’s own. It often involves a person in a position of trust: a caregiver, an adult child who controlled access to the parent, a financial advisor. Courts look at whether the testator was isolated from other family members, whether the influencer participated in drafting or arranging the will, and whether the terms depart from what the testator had previously expressed.
In many states, if you can show that a beneficiary had a confidential or fiduciary relationship with the testator, had the opportunity to exert influence, and received an unexpectedly large share, a legal presumption of undue influence applies. That shifts the burden to the other side to prove the will was genuine. It is one of the most powerful tools available to contestants because what happens behind closed doors between a vulnerable person and an influencer is otherwise very hard to prove.
Improper Execution
Wills must follow signing formalities, and the rules vary by state. Most states require the testator to sign in the presence of two disinterested witnesses who also sign. Some states require notarization. A will that wasn’t properly signed, was witnessed by someone who stands to inherit under it, or otherwise failed the state’s formal requirements can be invalidated on this ground alone, even if the document accurately reflected the testator’s wishes.
Fraud or Forgery
Fraud covers situations where the testator was tricked into signing something they didn’t understand was a will, or fed false information that changed the terms. Forgery is simpler: the signature isn’t genuine, or the document was altered after signing.
Revocation or a Later Will
A newer, properly executed will generally supersedes older versions. Evidence that the testator physically destroyed the contested will, or executed a formal revocation, is also a ground for challenge.
Check for a No-Contest Clause First
Many people walk into a trap here. Some wills include a no-contest clause (also called an “in terrorem” clause) providing that any beneficiary who challenges the will forfeits their inheritance. If the will leaves you $100,000 and you contest and lose, the clause treats you as if you predeceased the testator. You get nothing.
Most states enforce these clauses but interpret them narrowly. Many recognize a “probable cause” exception: if you had a reasonable basis for believing the contest would succeed, the clause doesn’t trigger even if you ultimately lose. The standard is whether the evidence would lead a reasonable person to conclude there was a substantial likelihood of success. Proof of forgery or undue influence can establish probable cause. A handful of states, including Florida, refuse to enforce no-contest clauses at all.
If the will includes such a clause and leaves you anything of value, get legal advice before filing. The risk math changes sharply with your state’s rules and the strength of your evidence.
Know Your Filing Deadline
Will contests run on strict deadlines that vary significantly by state. The clock typically starts when the will is admitted to probate or when you receive formal notice of the probate proceeding. Depending on the jurisdiction, you may have as little as three months or as long as two years. Some states measure from the date you’re personally notified; others run the clock from the first public notice.
In some states, you can file a “caveat” before the will is formally admitted to probate, putting the court on notice that you intend to challenge the document. That can buy time and prevent the estate from being distributed before your objections are heard. Miss the deadline and the right to contest is almost always gone, regardless of the merits. If you’re even considering a challenge, pinning down your state’s deadline is the first task.
Gather Evidence Before You File
A will admitted to probate is presumed valid, so the burden of proving otherwise falls on you. Assembling the right materials in advance saves time and helps an attorney evaluate whether the case is worth pursuing.
The Will and Related Documents
You need a copy of the contested will, any prior wills or codicils, and the death certificate. Comparing earlier versions against the contested one is often critical, especially when the changes favor someone with access to the testator near the end of their life.
Medical Records
If capacity is the ground, medical records from around the signing date are the most important evidence you’ll gather. Hospital records, physician notes, medication lists, and cognitive assessments all speak to whether the testator understood what they were doing.
Getting them involves a hurdle. HIPAA protects a deceased person’s health information for 50 years after death. To obtain the records, you typically need authorization from the estate’s personal representative, meaning the executor or administrator appointed by the court. If the executor is the person you suspect of exerting undue influence, that’s an obvious conflict. Your attorney can then petition the court for access or issue a subpoena during discovery.1HHS.gov.

Financial and Communication Records
Bank statements, property records, and financial account activity can reveal patterns consistent with undue influence: large transfers to the suspected influencer, changes to beneficiary designations, unusual spending. Emails, text messages, letters, and testimony from friends or caregivers who observed the testator’s condition or interactions with the alleged influencer can also carry real weight.
Identifying Interested Parties
You’ll need a list of everyone with a stake in the outcome: all beneficiaries named in the contested will, beneficiaries from any prior will, the executor, and legal heirs who would inherit if the will were invalidated. The court requires that each of them receive formal notice of the contest.
File the Petition and Serve Notice
The contest is initiated by filing a petition (sometimes called a complaint or caveat, depending on the state) with the probate court in the county where the deceased lived. The petition identifies you and your relationship to the deceased, states your legal grounds, and lays out the facts supporting the claim. Most courts have specific forms available through the clerk’s office or the court’s website.
Filing requires a court fee, which varies by jurisdiction. After filing, you must serve notice on all interested parties, usually by certified mail or personal delivery through a process server. Failing to properly notify everyone can delay the case or hand the other side grounds to challenge the proceedings.
What Happens After You File
Once the petition is filed and served, the case moves into active litigation. The court schedules an initial hearing or case management conference to set timelines and address preliminary issues. Then comes discovery, where both sides exchange evidence through written questions (interrogatories), document requests, and depositions, which are recorded interviews under oath. If capacity is at issue, depositions of the testator’s doctors, caregivers, and the witnesses to the will are often the most revealing.
Expert witnesses can play a significant role. Medical experts may testify about the testator’s cognitive state, and forensic document examiners can analyze signatures or detect alterations. These experts charge substantial hourly fees, often several hundred dollars per hour, which accumulates fast during preparation and trial.
The vast majority of will contests, by some estimates over 90%, settle before a full trial. Settlement negotiations or court-ordered mediation give both sides a chance to reach agreement without the expense and uncertainty of trial. If no settlement is reached, the case goes before a judge or, in some states, a jury.
Possible Outcomes
- Will upheld. The court finds no legal defect and the estate is distributed as written. You bear your own legal costs, and if a no-contest clause applies, you may also lose whatever the will originally left you.
- Partial invalidation. The court strikes down specific provisions, such as a bequest tainted by undue influence, while leaving the rest of the will intact.
- Full invalidation. The entire will is thrown out. If a valid earlier will exists, that version controls the estate. If none exists, the estate passes under the state’s intestacy laws.
- Settlement. The parties negotiate a redistribution of assets without a final court ruling on validity. Settlements can involve cash payments, specific property transfers, or other arrangements tailored to the family’s situation.
Costs and Financial Risk
Will contests are expensive, and the costs catch people off guard. A relatively straightforward case that settles early can still cost tens of thousands of dollars. Complex cases with expert witnesses, extensive discovery, and trial can run into the hundreds of thousands. The main cost categories are attorney fees, expert witness fees, court filing and service costs, and deposition expenses.
Most probate litigation attorneys charge by the hour, with rates varying by location and experience. Some handle will contests on contingency, taking a percentage of what you recover instead of billing hourly. Contingency arrangements are more common with large estates and strong cases, because the attorney is betting their own time on the outcome. Whether hourly or contingency, understand the fee structure before signing an engagement letter.
Risk runs in both directions. If you contest and lose, you typically bear your own attorney fees and may forfeit an inheritance under a no-contest clause. Even if you win, legal costs come out of your recovery or, in some cases, the estate, which means every beneficiary shares the burden. Run the numbers before filing.
Alternatives to a Full Contest
Filing a lawsuit isn’t always the best path, even with legitimate grounds. Mediation, where a neutral third party helps the sides negotiate, can resolve many estate disputes faster and at a fraction of the litigation cost. Courts in some jurisdictions require mediation before allowing a contest to proceed to trial.
A family settlement agreement is another option. All interested parties negotiate a redistribution of assets and memorialize it in a binding contract. Courts generally approve these agreements as long as everyone with a legal stake consents and the terms don’t violate any legal requirements. This works best when everyone acknowledges the will has problems but wants to avoid the cost and family damage of a courtroom fight.
When to Bring in an Attorney
Will contests involve rules of evidence, burdens of proof, and procedural requirements that are hard to handle without legal training. An experienced probate litigator can evaluate whether your evidence supports a viable claim, estimate the realistic range of outcomes, and flag risks you might not see, like a no-contest clause or a standing problem. Most probate attorneys offer an initial consultation where they assess the basic facts before you commit to filing. That consultation is often the most cost-effective step in the entire process, because it can keep you from pursuing a case that was never going to succeed.
