How to Contest a Will: Grounds, Standing & Process
Contesting a will means asking a probate court to reject it — but only certain people can file, only recognised grounds count, and deadlines are often months away.
Key takeaways
- Only an "interested person" who would gain if the will failed has standing.
- Being left out or treated unfairly is not, by itself, a legal ground.
- Deadlines run from probate filing or notice — e.g. California 120 days, Florida three months.
- Most contests settle or mediate; trial is expensive and uncertain.
- A no-contest clause can cost a share, but many states spare challenges with probable cause.
Learning a will leaves you out is painful. It can be challenged — through a formal court process, on specific grounds, and quickly. This guide covers who can file, what to prove, deadlines, and costs. General information, not legal advice.
Who has standing to contest a will?
Courts do not let just anyone challenge a will. You need standing: a direct financial interest — usually a beneficiary under an earlier will cut out by the newer will, an heir who would inherit without a valid will, or, in some states, a creditor. Others normally cannot file.
Standing also shapes what you gain. If the will fails, the court usually falls back to the earlier will, or intestacy. Would you inherit more there? If not, a win may not help.
Grounds for contesting a will
Disappointment is not a ground. A testator is generally free to choose who inherits, unless a state spousal-share law says otherwise. You must prove a recognised ground, usually bearing the burden.
| Ground | What you must show | Typical evidence |
|---|---|---|
| Lack of capacity | At signing, the testator did not understand making a will, their property, or their heirs. | Medical records; doctor testimony; expert opinion on signing day. |
| Undue influence | Pressure overbore the testator's free will, substituting another's wishes. | Isolation; control of visits; sudden unexplained changes. |
| Fraud | The testator was tricked into signing or into terms they would not have chosen. | False statements; misleading documents; witness accounts. |
| Forgery | A signature or part of the document is not genuine. | Handwriting expert; comparison signatures. |
| Improper execution | Signing or witnessing did not meet state law, such as too few witnesses. | Witness testimony; drafting attorney's file. |
| Later will / revocation | A newer valid will replaced the old one, or it was validly revoked. | The later will; revocation language; proof of destruction. |
Two cautions: capacity is judged at signing, so a diagnosis alone rarely wins; and undue influence is more than persuasion — courts look for patterns like a caregiver isolating an elderly person, as New Jersey guidance shows. If making your own will, see whether you need a lawyer to make a will.
How long do you have? Deadlines vary by state
There is no national deadline. In most states the clock runs from probate admission or formal notice — not death, nor when you first heard the contents. Miss it and the court will usually refuse the case, however strong your evidence. State-by-state deadlines vary widely.
Three verified examples: California, 120 days from probate admission; Florida, three months from service of the notice of administration; Illinois, six months from probate admission. Other states are shorter, some longer. So find your state's exact deadline at once. If probate has not opened, some courts allow an advance caveat; first check when probate is required.
How the process works, step by step
First, get a candid attorney review of standing, ground, and evidence before spending money. Second, file the objection in probate court within the deadline; the executor and beneficiaries are then notified. Third comes discovery: documents, depositions, and medical and financial records.
Fourth, most courts push parties toward mediation, where many contests settle for a compromise share. Fifth, if settlement fails, trial follows, with the contestant generally bearing the burden of proof. Either side may appeal, adding time and cost.
What it costs — and who pays
Assume you pay your own costs up front. Attorneys commonly charge $250 to $500 per hour, sometimes more in major cities. An early settlement may cost $5,000 to $10,000; trial can run $50,000 to $100,000 or more per side, per average cost guides. Add filing fees, depositions ($2,000 to $5,000 each), and experts ($3,000 to $7,500 each). Contingency fees are uncommon, so ask early about retainers.
Illustrative example: contesting a $120,000 share, settling after discovery at $15,000 to $30,000 in costs, leaves $90,000 to $105,000 if you win — but a $15,000 to $30,000 loss if you lose. At $60,000 trial costs, even a win leaves far less. Illustrative ranges only, not a quote. For uncontested context, see how long probate takes, how much probate costs, and estate-planning attorney fees.
No-contest clauses: do they stop you?
A no-contest (in terrorem) clause says a challenger forfeits what the will gave them. It only binds named beneficiaries, not an heir left nothing who would inherit under intestacy or an earlier will. In most states it is not enforced with probable cause — facts leading a reasonable person to believe the challenge had a real chance. Florida is an exception, where such clauses are generally unenforceable, as no-contest guidance explains.
Weigh it against your stake: if the will leaves you $80,000 and your challenge is speculative, losing could cost that plus legal fees. If left little or nothing, or your evidence is strong, it may be a paper tiger.
Realistic chances — and alternatives
Be honest about the odds. Courts presume a properly executed will valid, the testator cannot testify, and you carry the burden. Success usually needs concrete evidence — signing-period medical records, a witness to pressure, or a document expert proving forgery — not a conviction that "this isn't what they wanted." If evidence is thin, a smaller settlement is often better.
Alternatives help: an attorney's letter may prompt settlement; mediation keeps the result in your hands. To spare your own family this, consider ways to avoid probate disputes. Decide quickly: the deadline most often ends a contest.
This is general US guidance only; law varies by state and deadlines are strict. Consult a probate attorney in your state before filing — not legal advice.
