Capacity and Estate Planning: When Is It Too Late to Sign?
New Title
New Paragraph
In Florida, a person can sign a will or revocable trust if they understand what they own, who their family is and the effect of the document. A diagnosis of dementia does not automatically prevent signing, but once that understanding is gone, the family's main option is usually a court guardianship.
We often get calls from families after a parent's memory has started to slip. The first question is always the same: is it too late?
The legal standard
Florida requires a person making a will to be "of sound mind" (§ 732.501). Courts look at whether the person understood, in a general way, the nature and extent of their property, their relationship to the people who would naturally inherit, and the practical effect of the will. The capacity needed to create a revocable trust is the same as for a will (§ 736.0601). A power of attorney is a contract, so the person must understand what authority they are giving.
What a diagnosis does and doesn't mean
- Early-stage dementia or memory loss does not automatically mean a person lacks capacity.
- Capacity is measured at the moment of signing. People can have good days and bad days.
- A lawyer meets with the client, often privately, to confirm they understand and are acting freely.
- Where there is doubt, a letter from the treating physician can help support the plan.
What happens if it's too late
If a person can no longer understand and sign, no one can sign a power of attorney or health care surrogate for them. Family members can often make medical decisions as a health care proxy (§ 765.401), but for finances the usual path is guardianship under Chapter 744 of the Florida Statutes, which requires a court case, an examining committee, ongoing court reporting and annual costs. See our comparison of guardianship and power of attorney.
Plan while you can
A durable power of attorney, a health care surrogate designation and a preneed guardian designation cost far less than a guardianship and let you choose who helps you. If a loved one has a new diagnosis, call us promptly. Timing matters.
