Legal Documents Every Sibling in a Caregiving Family Should Know About

You may not be the sibling who holds the power of attorney. But if your parent has a medical emergency and the sibling who does hold it isn’t reachable, everyone needs to know what documents exist and where they are. Legal documents in a caregiving family shouldn’t be one sibling’s private knowledge. This guide explains what each document does and why every sibling should understand them before the documents are needed.

This guide explains what the key legal documents are, what they do, and how families can put them in place before they’re needed. This is informational — an attorney in your state can advise on the specifics for your situation.

Why These Documents Matter

Without the right legal documents:

• Hospitals and doctors cannot share your parent’s health information with you. HIPAA privacy rules treat adult patients as autonomous individuals, and unless your parent has explicitly authorized it, providers can’t tell you what’s happening.
• You cannot make medical decisions for your parent if they become unable to make them for themselves, unless you have legal authority to do so.
• You cannot manage your parent’s finances, pay their bills, or handle their accounts — even if they want you to and even if you’re their closest family member.
• If your parent becomes incapacitated without documents in place, someone may need to go to court to become their guardian or conservator, which is expensive, slow, and often painful for the family.

Getting these documents in place is one of the most practical things a family can do for a parent who is aging.

Healthcare Power of Attorney (Healthcare Proxy)

A healthcare power of attorney (sometimes called a healthcare proxy or medical power of attorney) is a legal document in which a person designates someone to make medical decisions on their behalf if they become unable to make them for themselves.

What it covers:

• Decisions about medical treatment, surgery, hospitalization
• Decisions about starting or stopping life-sustaining treatment
• Choices about where care is provided (home, hospital, nursing facility)
• Anything else related to medical care when the person can’t speak for themselves

What it doesn’t cover:

• Financial matters
• Property or assets

The person named is called a healthcare agent or healthcare proxy. They are legally authorized to make healthcare decisions based on what they believe the person would want — ideally guided by conversations they’ve had and by the living will (see below).

How to get it: This document typically requires an attorney, though many states have statutory forms that can be completed without one. Requirements (witnesses, notarization) vary by state.

Financial Power of Attorney (Durable Power of Attorney)

A financial power of attorney (often called a durable power of attorney, or DPOA) authorizes someone to manage financial and legal matters on another person’s behalf.

What it can cover:

• Banking and investments
• Paying bills
• Managing property
• Filing taxes
• Handling insurance
• Making gifts or transferring assets

Durable vs. general: A standard (general) power of attorney becomes invalid if the person becomes incapacitated — the opposite of when you need it most. A durable power of attorney remains in effect even if the person becomes mentally incapacitated. When planning for aging, you want durable.

Springing vs. immediate: Some powers of attorney “spring” into effect only when a specific condition is met (usually incapacity confirmed by physicians). Others take effect immediately. Each approach has tradeoffs — an elder law attorney can advise on what makes sense for your situation.

This is a significant document. The person named has substantial authority over your parent’s finances and assets. It should be someone they trust deeply, and ideally a backup agent should be named as well.

Living Will (Advance Directive)

A living will (also called an advance directive or directive to physicians) is a document in which a person specifies what medical treatment they want — or don’t want — if they become unable to communicate their wishes.

Common topics:

• Use of life-sustaining machines (ventilators, feeding tubes)
• Resuscitation preferences (CPR)
• Organ donation
• Preferred setting for end-of-life care (hospital, home, hospice)
• Comfort care preferences

A living will provides guidance to the healthcare agent and to medical providers. Even with a healthcare agent in place, having your parent’s own wishes documented in writing is important — it makes it easier for the agent to advocate confidently and reduces the emotional weight of decision-making.

How to get it: Most states have standard forms. An attorney isn’t required, though legal review is helpful. The document must typically be witnessed and/or notarized.

POLST / MOLST (Physician’s Orders)

A POLST (Physician Orders for Life-Sustaining Treatment) — called MOLST, MOST, or other names in some states — is different from an advance directive. It is an actual physician’s order, signed by a doctor, that specifies what treatments a patient should or should not receive.

When it matters: POLST forms are most relevant when a person is already seriously ill or near the end of life. Unlike a living will (which instructs caregivers on what the person would want), a POLST is a medical order that emergency responders and care providers are required to follow.

Without a POLST: If your parent has a cardiac arrest at home and doesn’t have a POLST in place, emergency responders are legally required to attempt resuscitation — even if that’s not what your parent would have wanted.

How to get it: A physician, nurse practitioner, or physician assistant completes the form with the patient. It belongs where care providers can find it quickly — typically posted in a visible location at home.

HIPAA Authorization

The Health Insurance Portability and Accountability Act (HIPAA) restricts who medical providers can share patient information with. A HIPAA authorization is a signed document in which your parent explicitly authorizes specific people — you, a sibling, a care coordinator — to receive their health information.

Why it matters: Even with a healthcare power of attorney in place, providers sometimes require a separate HIPAA authorization to share day-to-day information (test results, appointment summaries, prescription records) with family members. Having this in place prevents frustrating situations where a doctor can’t update you on your parent’s condition because you’re not formally authorized.

How to get it: Most medical practices have their own HIPAA authorization form. Ask at your parent’s primary care office and any specialist offices they see regularly.

When to Get These Documents

The honest answer: before you need them.

These documents require the person to be mentally competent at the time they sign. Once dementia, a stroke, or another condition has affected your parent’s ability to understand what they’re signing, it may be too late. If your parent has a new diagnosis of mild cognitive impairment, act quickly.

For families whose parents are still healthy, now is a natural time. A straightforward conversation framed around planning — “We want to make sure we know what you’d want and that we can help if something happens” — tends to go better than one framed around crisis or decline.

Where to Keep These Documents

Documents are only useful if they can be found when they’re needed.

• Give copies to the named healthcare agent and financial agent
• Give copies to your parent’s primary care physician and any specialists
• Keep the original in a secure but accessible location (not a safe deposit box that requires court access to open)
• Know where the documents are before you need them — and make sure siblings and other involved family members know where they are too

Some families keep a summary document that lists what documents exist, where they are, and who the agents are. This is particularly valuable when care is coordinated across siblings or when a parent travels or spends time in multiple locations.

Finding Help

Elder law attorneys specialize in exactly these documents and can ensure they are properly drafted for your state. Many offer free initial consultations. To find one, the National Academy of Elder Law Attorneys (NAELA) has a search directory at naela.org.

Area Agencies on Aging often have low-cost legal aid referrals. Use the Eldercare Locator at eldercare.acl.gov to find your local agency.

Keeping Caregiving Organized

When these documents are in place, day-to-day caregiving coordination — knowing who’s handling what, who was at the last appointment, what the doctor said — becomes an ongoing family effort.

Zenia Care gives caregiving families a shared, organized space for exactly this: medications, appointments, tasks, and care updates accessible to everyone who should have them.
