Power of attorney for an elderly parent: a practical guide
A power of attorney (POA) is the single most useful legal document for an aging parent — and the one most families wait too long to put in place. This guide explains what a POA does, the two types you need, how to set one up, and what your options are if your parent has already lost the capacity to sign.
What a power of attorney does
A POA is a written authorisation that lets one person (the 'agent' or 'attorney-in-fact') act on another person's behalf. It does not transfer ownership of anything — your parent stays in control until they choose otherwise or lose capacity. Without a POA, families often have to go to court for a guardianship or conservatorship, which is slow, expensive (typically $3,000–$10,000) and public.
The two types every elderly parent needs
Financial POA (sometimes called a 'durable POA' or 'general POA'): lets the agent pay bills, manage bank accounts, file tax returns, sell property and apply for Medicaid. Healthcare POA (also called a 'healthcare proxy' or 'medical POA'): lets the agent make medical decisions if your parent can't speak for themselves. These are usually two separate documents and may have different agents.
Durable vs springing
A 'durable' POA stays in effect even if your parent becomes incapacitated — this is what you want for aging parents. A 'springing' POA only activates after a doctor certifies incapacity, which sounds safer but causes long delays and often requires multiple physician statements. Most elder-law attorneys recommend durable.
How to set one up
Use an elder-law attorney where possible — fees are typically $200–$600 for a basic financial and healthcare POA pair, far less than a contested guardianship. State-specific forms are also available from your state bar association or AARP. Documents must be signed in front of a notary; many states also require two witnesses. The agent does not need to be present at signing.
Choosing the right agent
Pick someone who is organised, honest, lives close enough to act, and will outlive your parent. Don't default to the eldest child — pick the most suitable one. Name a successor agent in case the first can't serve. Avoid co-agents (two people who must agree) unless family dynamics demand it; they slow everything down.
Common mistakes
Waiting until after a dementia diagnosis (by then, capacity may be in dispute). Using a generic online form that omits state-specific powers (e.g. the right to make gifts for Medicaid planning). Not telling banks and brokerages — some institutions require their own internal POA forms. Forgetting to update healthcare wishes alongside the POA (a living will / advance directive is a separate document covering end-of-life choices).
What if my parent has already lost capacity?
If your parent can no longer understand what they're signing, you cannot get a POA — you must petition the court for guardianship (of the person) and/or conservatorship (of finances). Start with the probate court in your parent's county and expect $3,000–$10,000 in legal fees. The court appoints a guardian, often the family member who applied, and supervises decisions ongoing.
