The three documents
If a stroke happened tomorrow, who could legally pay your parent's mortgage, talk to their doctors, or say what they would have wanted? Without three specific documents, the honest answer is often no one — until a judge decides. This is the paperwork that keeps those decisions inside the family, and it only works if it's signed while your person can still legally sign.
What the three documents are
- Durable power of attorney (financial). Names a trusted person to handle money and property — pay bills, manage accounts, deal with insurance. "Durable" is the key word: it keeps working after the person loses capacity, which is the whole point (American Bar Association — americanbar.org).
- Healthcare proxy (healthcare power of attorney). Names who makes medical decisions when your person can't. Doctors need one named decision-maker; without it, disputes between equally loving children go unresolved at the worst possible bedside moment.
- Advance directive / living will. States what treatment your person would and wouldn't want — life support, resuscitation, tube feeding. Most state forms combine this with the healthcare-proxy appointment in one document (National Institute on Aging — nia.nih.gov).
What they cost — including free
Advance directive and healthcare proxy forms are free in every state — AARP keeps the official forms for all 50 states and D.C. downloadable at aarp.org, and CaringInfo (the hospice organizations' nonprofit) does the same at caringinfo.org. Witnessing and notarization rules vary by state and are printed on the forms.
With an attorney, a 2026 survey of 909 U.S. law firms found a financial power of attorney alone runs a median ~$300, and a complete will-based package — will, both powers of attorney, advance directive — a median of about $1,000, usually flat-fee (legaltemplates.net). For anything involving significant assets, a home, or Medicaid timing, families generally use an elder-law attorney — that conversation overlaps with the five-year window.
What happens without them: guardianship court
If someone loses capacity with no documents, the family's remaining path is petitioning a probate court for guardianship or conservatorship: a court petition, medical evaluations, a court investigator, an attorney appointed for your person, a hearing — commonly running several thousand dollars uncontested and far more if relatives disagree, followed by permanent court supervision with annual reports. The person loses legal rights a judge doesn't restore lightly. Every elder-law source we can find describes it the same way: the expensive, public, slow version of the decision the documents would have made private and instant.
POLST — the fourth document, for the seriously ill only
A POLST (Portable Medical Orders; called MOLST/MOST/POST in some states) is different: it's a medical order signed by a clinician, for people already seriously ill or frail — and unlike a living will, emergency crews can follow it. Healthy adults don't need one; every adult needs an advance directive (National POLST — polst.org).
Where the public record stops — and who to ask
Which forms does your state use, and does your family's situation call for an attorney? That answer depends on your state and your situation, and it belongs to the people who decide it — not to us. Here is who has it, and exactly what to ask so you arrive prepared instead of lost.
Who to ask: your Area Agency on Aging (many run free or low-cost legal-assistance programs for 60+ under the Older Americans Act); an elder-law attorney for anything involving assets or Medicaid timing
What to ask them:
- Does our AAA have a legal-assistance program that helps with these documents at no cost?
- What are our state's witnessing and notarization requirements for each document?
- Should our power of attorney take effect now, or only upon incapacity — and how is incapacity determined here?
- Is there anything in our situation (property, blended family, early dementia signs) that makes attorney drafting safer than the free forms?
You now know more than most people who walk into that office. That is the whole point of this page.
Who helps you locally — free, and on your side. You do not have to figure this out alone. Your Area Agency on Aging gives free options counseling; reach any of them through the federal Eldercare Locator at 1-800-677-1116 or eldercare.acl.gov (Administration for Community Living). More on the four people who help — and what each one does — on Who helps me locally.
Quick answers
What legal documents does an elderly parent need?
Three core documents, per the American Bar Association and National Institute on Aging: a durable power of attorney for finances, a healthcare proxy (healthcare power of attorney) for medical decisions, and an advance directive/living will stating treatment wishes. A POLST — portable medical orders — is a fourth for people who are already seriously ill. All must be signed while the person still has legal capacity.
How much does a power of attorney cost?
A 2026 nationwide survey of 909 law firms found a financial power of attorney costs a median of about $300 from an attorney, and a complete will-based estate-planning package (will, powers of attorney, advance directive) a median of about $1,000, usually flat-fee. Advance directive and healthcare proxy forms themselves are free from every state — AARP and CaringInfo host the official forms.
What happens if a parent becomes incapacitated without a power of attorney?
The family generally must petition a probate court for guardianship (over the person) and/or conservatorship (over finances): medical evaluations, a court investigator, an appointed attorney, and a hearing — typically thousands of dollars even uncontested, far more if contested — followed by ongoing court supervision. The documents exist precisely to keep that decision inside the family instead.
