A family member has passed. The will is read. Something doesn't feel right — maybe you were unexpectedly left out, or the terms seem completely unlike what your loved one would have wanted.

Can you challenge it? Maybe. But it's not simple.

What Does It Mean to "Contest" a Will?

Contesting a will means formally challenging its validity in probate court. It's a legal proceeding that asks the court to declare the will — or part of it — invalid.

Here's what it's not: contesting a will is not about disagreeing with how assets were divided. You need legal grounds. Simply being unhappy with your share is not sufficient.

It's also different from making a claim against the estate — for example, if the deceased owed you money. That's a creditor claim, not a will contest.

Legal Grounds for Contesting a Will

Courts will consider a will contest only if you can demonstrate one of these recognized grounds:

1. Lack of Testamentary Capacity

The person who made the will (the "testator") didn't understand what they were signing. This typically involves:

• Dementia or Alzheimer's at the time the will was executed
• Severe illness affecting cognitive function
• Mental impairment from medication or substance use

The key is the testator's mental state at the time the will was signed — not before or after. A person with early-stage dementia may have had capacity on certain days but not others.

2. Undue Influence

Someone pressured, manipulated, or coerced the testator into making changes to their will. Common patterns include:

• A caregiver who isolated the testator from family
• A new "friend" who became the primary beneficiary
• Sudden will changes that favor one person who had disproportionate access to the testator
• Changes made when the testator was physically or emotionally vulnerable

Undue influence is the most commonly alleged ground — and one of the hardest to prove.

3. Fraud or Forgery

The will was fabricated, the signature was forged, or the testator was tricked into signing a document they believed was something else. This includes:

• Presenting a different document for signature
• Misrepresenting the contents of the will
• Forging the testator's signature

4. Improper Execution

The will wasn't signed or witnessed correctly per state or provincial law. Requirements vary but typically include:

• The testator must sign the will (or direct someone to sign on their behalf)
• A specific number of witnesses must be present (usually two)
• Witnesses must sign in the testator's presence
• Some jurisdictions require notarization

Even small procedural errors can invalidate a will. For specifics, see our state guides for California, Texas, Florida, and New York.

5. Revocation

A newer will exists that supersedes the one being probated. If the testator executed a more recent will that revokes all prior wills (standard language in most wills), the older document is invalid.

Who Can Contest a Will?

Not just anyone can contest a will. You need "standing" — legal terminology meaning you would be affected if the will were invalidated.

People who typically have standing include:

• Named beneficiaries in the current will who believe it was improperly made
• Beneficiaries from a previous will who were removed from the current version
• Intestate heirs — those who would inherit under state law if there were no will (typically spouse, children, parents, siblings)
• Creditors of the estate — in some jurisdictions and limited circumstances

If you wouldn't benefit financially from the will being invalidated, you generally can't contest it — no matter how strongly you feel.

Time Limits for Contesting

Missing the deadline means losing the right to contest. These time limits are strict:

United States

Canada

Check your specific jurisdiction — these deadlines can be unforgiving. In Florida, you could lose your right to contest in less than three weeks.

What to Expect If You Contest

Before filing, understand what you're getting into:

It's expensive. Legal fees for a will contest typically range from $10,000 to $100,000+, depending on complexity. In some cases, legal fees can consume a significant portion of the estate value — meaning everyone loses.

It takes time. Will contests can take months to years to resolve, delaying distribution of the entire estate to all beneficiaries.

It strains relationships. Family relationships are often permanently damaged. Even if you win, you may lose family connections.

Success rates are not high. Courts generally respect the documented wishes of the deceased. The burden of proof is on the person contesting, and courts set a high bar for overturning a will.

Many contests settle out of court. Rather than a full trial, parties often negotiate a settlement. This can be faster and less expensive — but still involves significant legal costs.

Consider mediation before litigation. Many jurisdictions now offer or require mediation before a will contest proceeds to trial. Mediation is less adversarial, less expensive, and preserves family relationships better than litigation.

When NOT to Contest

Be honest with yourself about whether contesting is appropriate:

• You simply disagree with how assets were split — this is not legal grounds for a contest
• The will was properly executed and the person was competent — disagreement with their choices is not the same as invalidity
• You're motivated by emotion rather than evidence — grief and surprise are natural, but they don't constitute legal grounds
• The cost of contesting would exceed what you'd gain — if the estate is small or your potential share is modest, legal fees may make contesting financially irrational
