What this means in practice
Deadlines for will contests are often short and strictly applied. Knowing exactly which event starts the clock in the state where the will is probated, such as the date of admission, the date notice was mailed, or the date of publication, matters as much as knowing the length of the period.
Only people with a legal stake in the estate can usually contest a will, such as heirs who would inherit without the will or beneficiaries named in an earlier will. A contest also needs a recognized legal ground. Being disappointed with the amount left to you is generally not enough on its own.
A no-contest clause (also called an in terrorem clause) says a beneficiary who challenges the will loses their gift. Whether such a clause is enforced, and whether there is an exception for challenges brought with probable cause or in good faith, depends on state law. Anyone weighing a challenge, and anyone drafting a will, can check the state statute and may want to talk to a probate attorney.
General information, not legal advice. Laws change, and cities can add their own rules, so check the current statute before you rely on it.
