Proving your testamentary capacity as you develop an estate plan

On Behalf of Kerley & Talken PC | Oct 14, 2025 | Estate Planning

Disputes over an estate plan can fracture family relationships and even lead to costly litigation. Many such disputes arise when beneficiaries are surprised by final decisions.

One way to reduce the risk of conflict is by proactively demonstrating testamentary capacity, which is the legal ability to make informed decisions about your estate. Documentation and thoughtful planning can protect your wishes and shield your legacy from disputes.

Schedule a formal capacity evaluation

A cognitive assessment by a physician or psychologist provides objective evidence of your mental fitness. This is especially vital if you’re older, have a condition that affects cognition or expect family conflict. Obtain written documentation of the evaluation to include in your estate planning records.

Involve trusted witnesses during signing

Having neutral, credible witnesses present when you sign estate plan documents can help confirm your mental clarity and voluntary intent. Choose individuals who are not beneficiaries and who can attest to your demeanor, understanding and independence at the time of signing.

Keep detailed records of your planning process

Maintain a timeline of meetings, drafts and estate planning decisions. Include notes that show you considered alternatives, understood potential consequences and made your choices independently. Records like this can help prevent future claims of testamentary incapacity.

Consider video documentation

Some individuals choose to record a video of themselves discussing their estate plan. While this is not a legal requirement, a video record can be a powerful tool to show your clarity, intent and autonomy at the time of signing your will and other estate plan documents.

Taking these steps when creating your estate plan allows you to have greater confidence that your final wishes and your family’s inheritances are secure.
