Will disputes involving mental incapacity can be complicated and emotionally charged.

At OC Trial Group, APC, we assist clients in Orange County in both challenging and defending wills on the grounds of mental incapacity, providing the guidance needed to protect your interests in these complex disputes.

What Is Mental Incapacity in the Context of a Will?

Mental incapacity refers to a condition where an individual is unable to understand the consequences of their decisions, including making a will. In California, the law requires that the testator (the person creating the will) must have the mental capacity to make decisions about their property and the people who will inherit it. This includes:

  • Understanding the nature of the act (creating a will)
  • Recognizing the extent of their property
  • Comprehending who their heirs are and how their assets should be distributed
  • Understanding the effects of their decisions on their loved ones

A person may be considered mentally incapacitated if they are suffering from conditions such as dementia, severe mental illness, or cognitive decline due to age or medical conditions.

How to Prove Mental Incapacity in Will Disputes

Proving mental incapacity in a will dispute requires compelling evidence. Courts will consider several factors to determine whether a person had the mental capacity to create a valid will. Some key pieces of evidence include:

  • Medical Records and Testimony: Doctor’s notes, psychological evaluations, and medical expert testimony can help establish whether the testator was mentally sound at the time the will was made.
  • Witness Statements: Witnesses who were present when the will was signed can provide testimony regarding the testator’s behavior and decision-making ability.
  • Prior and Subsequent Wills: Comparing the contested will with previous versions can shed light on whether the testator’s wishes have changed suddenly or unusually, which may indicate a lack of capacity.
  • Cognitive Tests: In some cases, medical assessments or cognitive testing may be used to determine whether the testator understood the nature of the will and the effects of their decisions.

If you are challenging a will on the grounds of mental incapacity, gathering this type of evidence will be vital.

Defending Against Mental Incapacity Claims

If you are defending a will from a mental incapacity challenge, there are steps you can take to bolster the validity of the will:

  • Show the Testator’s Mental Capacity at the Time of Signing: Evidence that the testator was of sound mind at the time of signing the will can help counter claims of incapacity. This may include witness statements or testimony from those who observed the testator during the signing process.
  • Incorporate a Will Contest Waiver: If the will includes a no-contest clause, it may discourage anyone from challenging it, making it harder for parties to claim mental incapacity.
  • Consider the Testator’s History: If the testator had previously made decisions that align with the will’s distribution of assets, this may support the argument that they were not mentally incapacitated when the will was created.
