Georgia Power of Attorney and Dementia: Capacity Rules and Timing

A dementia diagnosis does not automatically destroy someone's ability to sign a power of attorney in Georgia. But the window closes permanently once the disease progresses beyond a certain point — and most families don't realize how narrow that window is until it's already shut.

What "Capacity" Means Under Georgia Law

To sign a valid power of attorney, the principal must have "contractual capacity" — the legal ability to understand and agree to a contract. Under Georgia law, this means the person must understand:

• What they're signing — that this document gives another person authority over their finances or healthcare decisions
• Who they're naming — that they're choosing a specific individual to act as their agent
• What powers they're granting — the general scope of authority the document provides
• The consequences — that the agent will be able to act on their behalf and make binding decisions

A person doesn't need to understand every legal nuance of the Uniform Power of Attorney Act. They need to grasp the basic concept: "I'm giving this person the right to handle my money and property."

Early and Moderate Dementia: The Window Is Still Open

Early-stage Alzheimer's and many forms of moderate dementia leave contractual capacity intact. A person who forgets where they put their keys, repeats questions, or needs help with complex financial tasks may still clearly understand that they're naming their daughter as their financial agent.

Georgia courts recognize the concept of "lucid intervals" — periods of clarity during which an otherwise impaired person has sufficient capacity to execute legal documents. A power of attorney signed during a lucid interval is valid, even if the principal was confused earlier that day or becomes confused again afterward.

The practical challenge is proving the lucid interval existed at the moment of signing. Two precautions help:

Medical documentation. Have the principal's physician evaluate and document their mental capacity on the same day as the signing. A letter stating that the doctor examined the patient and found them oriented, alert, and capable of understanding the document provides strong evidence of capacity.

Video recording. Record the signing session on video. The recording should show the principal responding to questions about what they're signing, who they're naming as agent, and what powers they're granting. This visual evidence is difficult to challenge later.

When the Window Closes

Once dementia progresses to the point where the principal cannot understand what a power of attorney does, no amount of careful signing procedures can create a valid document. A POA signed by someone without capacity is void from inception — it never had legal force, and any transactions the agent performed under it can be challenged and reversed.

Signs that capacity has likely been lost:

• The person cannot identify who they're naming as agent
• They cannot explain, even in simple terms, what the document does
• They respond to every question with agreement but show no actual comprehension
• Their physician has documented severe cognitive decline

What to Do When It's Too Late

If a family member has already lost capacity without a power of attorney in place, the only path forward in Georgia is court-supervised guardianship. A family member petitions the Probate Court for appointment as guardian of the person (healthcare decisions) and/or conservator of the property (financial decisions).

Guardianship proceedings require a court filing fee of $209 under the standardized SB 232 schedule, plus attorney fees typically ranging from $2,000 to $5,000. The court appoints a guardian ad litem to independently evaluate the situation, and the appointed guardian must post a surety bond, file asset inventories, and submit annual accountings.

Don't Wait for the Diagnosis

The strongest protection is executing a power of attorney before any cognitive concerns arise. A diagnosis of mild cognitive impairment or early-stage dementia should be treated as an emergency — not because the person lacks capacity today, but because the window is now visibly shrinking.

The Georgia Power of Attorney Kit walks families through the execution process with capacity considerations built in, including guidance on medical documentation and the witness requirements that apply specifically when signing with someone whose capacity may be questioned.
