Contesting a Will: Grounds, Standing, and Deadlines
A will contest is a formal legal challenge to whether a will is valid. It is far narrower than most people expect: only certain people are allowed to bring one, only on a short list of recognized legal grounds, and only within strict deadlines. Most contests do not succeed. This guide explains, in general terms, what a contest is, who can file one, the grounds courts recognize, and why the bar is high, so you can have an informed conversation with an attorney.

What a Will Contest Is
A contest asks the probate court to decide that a will, or part of it, is not legally valid and should not be followed. It is not a way to renegotiate an inheritance or to object simply because the outcome feels unfair. The law generally lets people leave their property to whomever they choose, even in ways relatives dislike.
Because a contest is litigation, it is decided on evidence and legal standards, not on sympathy. That is why the questions below, who may file, on what ground, and by when, matter more than how unfair a will may seem.
Who Can Contest
Courts only hear a contest from an interested person, meaning someone who would be financially affected if the will were set aside. In general that includes:
- an heir who would inherit under state intestacy law if there were no valid will;
- a beneficiary named in the will being challenged; and
- a beneficiary named in an earlier will that a later will replaced.
Someone with no financial stake, such as a friend who was simply left out, generally lacks standing. Who qualifies varies by state, and it is one of the first things an attorney checks.
The Recognized Grounds
A contest must rest on a legal ground, not a general grievance. The grounds courts commonly recognize are:
- Lack of testamentary capacity: the person did not understand what they owned, who their natural heirs were, or that they were making a will.
- Undue influence: someone in a position of power pressured or manipulated the person into a will that reflects the influencer's wishes, not the person's own.
- Fraud or forgery: the will was faked, or the person was tricked into signing it or into its terms.
- Improper execution: the will was not signed and witnessed the way state law requires.
- Revocation: the will was validly cancelled or replaced by a later one.
Each ground has its own legal standard and evidence requirements, and how they apply varies by state.
Deadlines and No-Contest Clauses
Two things make timing critical:
- Short, strict deadlines. The window to contest is limited and varies by state, often measured from when the will is admitted to probate or notice is given. Once it passes, the right to contest is usually gone.
- No-contest clauses. Many wills include a clause that disinherits a beneficiary who challenges the will and loses. States enforce these differently, and some will not enforce them against a good-faith challenge, but the risk is real.
The combination is why anyone weighing a contest looks at the calendar and the will's own terms early, with a probate attorney, rather than waiting.
Why Most Contests Fail
Courts start from a strong presumption that a properly signed and witnessed will is valid and reflects what the person wanted. Overcoming that takes real evidence, not suspicion, and the person who made the will is no longer here to testify. Contests are often expensive, slow, and emotionally hard on families, and most do not succeed.
None of that means a genuine problem should be ignored. It means these cases turn on specific facts and state law, so they are decided with a probate litigation attorney, not from a web page.
