Frequently Asked Questions

How much does it cost to contest a will in the US?
A will or trust contest can cost from $10,000-$25,000 for a matter that settles early to $75,000-$200,000+ if it goes to trial with depositions and expert witnesses on capacity or undue influence. Contingency arrangements are sometimes available for strong claims, but many probate lawyers bill hourly.
Who pays attorney fees in a US will contest?
Under the American Rule, each side generally pays its own attorney fees regardless of outcome. Some states allow fees to be paid from the estate if the contest was brought in good faith, and a personal representative defending the will can often use estate funds. A no-contest clause can penalize a losing challenger.
What is a no-contest clause?
A no-contest (in terrorem) clause disinherits any beneficiary who challenges the will or trust and loses. Its enforceability varies by state: some states enforce it strictly, others (like Florida) refuse to enforce it, and many will not enforce it if the challenger had probable cause. It raises the stakes of contesting.
What are the grounds to contest a will in the US?
Typical grounds are lack of testamentary capacity, undue influence, fraud, forgery, improper execution (not signed or witnessed per state law), and revocation by a later will. The contestant generally bears the burden of proof, and courts start from a strong presumption that a properly executed will is valid.
