A will can potentially be contested by an interested party, such as an heir who feels unfairly excluded, though a will that is clearly written, properly signed, and correctly witnessed is generally harder to successfully challenge.
General information
- Common grounds for a challenge include claims about mental capacity, undue influence, or improper signing.
- Following your state's exact signing and witnessing rules is one of the best protections against a successful challenge.
- A self-proving affidavit can make it easier to admit a will to probate without needing witnesses to testify in person.
Service steps to consider
- Make sure your will is signed and witnessed exactly according to your state's requirements.
- Consider a self-proving affidavit if your state allows one.
- Discuss any concerns about a likely challenge with a licensed attorney.
