Challenging a will begins with determining whether you have legal standing, identifying valid legal grounds, filing a petition with the probate court, gathering evidence, and presenting your case before a judge or mediator. A will cannot be challenged simply because someone is unhappy with the outcome. Courts generally require evidence of undue influence, lack of mental capacity, fraud, improper execution, or the existence of a newer valid will. Because strict deadlines apply and courts presume wills are valid, acting quickly and gathering strong evidence is essential.
Successful will contests are uncommon because the burden of proof falls on the person challenging the will.
Challenging a will means disputing its legal validity in court. You might believe the will was created under suspicious conditions or doesn’t represent the true intentions of the deceased. This challenge can delay or even change the distribution of assets in an estate.
The probate process verifies a will and handles the distribution of a person’s estate. However, when someone raises concerns about the will, a court may need to investigate before any property can be passed on to heirs.
Only people with legal standing may challenge a will. That means you must be directly affected by the outcome of the estate. You may have standing if:
If you’re unsure about your standing, consult a probate attorney before moving forward.
You cannot challenge a will just because you are unhappy with it. You must have valid legal grounds. The most common reasons include:
The person writing the will (the testator) must understand:

Undue influence happens when someone pressures or manipulates the testator into changing their will. This often involves:
If family members believe someone manipulated the deceased into changing a will, learn more about proving undue influence and how courts evaluate these claims.
If the will was forged or the testator was tricked into signing it, that’s fraud. For instance, someone might have slipped a will in front of the testator and claimed it was another document. Forged signatures also fall into this category.

Will contests are complex. Start by speaking with an estate or probate attorney. They can help determine if you have a valid claim and guide you through the process.

Each state has its own filing requirements, so check with the probate office or use an attorney.

You may also need expert witnesses such as doctors or handwriting analysts.
Your case may go to mediation or a full trial.

A woman makes a new will days before her sudden death, leaving everything to a new spouse and disinheriting her adult children. The children challenge the will, claiming undue influence and improper witness signatures. The court may investigate and possibly reinstate an earlier will.
Can you challenge a will after it has been accepted by the court? Yes, but timing is key.
