    Medical and Financial Authority Between Partners

    Authority to act for a partner comes from signed documents, not from the relationship, and the four that matter can be put in place long before anyone needs them.

    State rule 7 min read Authority For unmarried partners with no legal standing to act for each other, married couples who assume the certificate covers everything, anyone facing surgery, deployment, or a serious diagnosis

    The short answer

    A health care proxy, an advance directive, a HIPAA authorization, and a durable financial power of attorney together let a partner speak for you when you cannot. Married couples get some of this by default but not all of it, and unmarried partners get none of it. All four are signed while you still have capacity, and none can be created afterward.

    An abstract figure of numbered rules standing in for the questions this page answers about medical and financial authority between partners.

    What authority do partners have without any documents?

    Less than almost everyone assumes, and for unmarried partners, close to none. Hospitals and banks do not ask about relationships. They ask about legal standing, and legal standing comes from a document or from a statute that names you.

    Marriage supplies part of it. Most states place a spouse at or near the top of the list of people who may make medical decisions for an incapacitated adult when no proxy was named, and providers routinely treat a spouse as the person to talk to. That default is genuinely useful, but it is a default, meaning it applies only when nothing else was signed, and it varies from state to state in ways you will not learn until you need it.

    Marriage supplies almost nothing on the financial side. A spouse cannot sign for the other spouse's individually held brokerage account, cannot refinance a mortgage on property titled in the other spouse's name, and cannot manage a business interest that belongs to the other spouse. Unmarried partners are outside every default, which is why the documents below are not optional for them. The wider set of gaps unmarried couples live with is set out in property and debt for couples who never marry.

    Which documents actually do the work?

    Four, and each does something the others do not. Signing three of them and skipping the fourth leaves a specific and predictable hole.

    DocumentWhat it authorizesWhat it does not cover
    Health care proxy or medical power of attorneyNaming a person to make treatment decisions if you cannotAccess to your records; anything financial
    Advance directive or living willYour own instructions about life-sustaining treatmentSituations you did not anticipate
    HIPAA authorizationLetting providers release records and speak to a named personAny power to decide anything
    Durable financial power of attorneyManaging accounts, bills, property, taxes, insuranceMedical decisions; Social Security payments
    Beneficiary designations and willWho receives what after deathAnything at all while you are alive

    The word durable on a financial power of attorney is not decoration. An ordinary power of attorney lapses precisely when the principal becomes incapacitated, which is the moment you needed it. Durable language keeps it alive. A springing power takes effect only on incapacity, which sounds safer but forces the agent to prove incapacity before a bank will act, and that proof can take weeks.

    Note also that a power of attorney does not reach federal benefit payments. The Social Security Administration does not accept powers of attorney and instead uses its own representative payee process, which requires a separate application and its own findings. Assuming your document covers benefits is a common and consequential mistake.

    Why does a partner need a separate records authorization?

    Because deciding and knowing are different permissions. Federal health privacy rules restrict who a provider may share information with, and while providers have discretion to speak with people involved in a patient's care, discretion is exactly what you do not want to rely on at two in the morning with an unfamiliar charge nurse.

    A HIPAA authorization removes the judgment call. It names the person, states what may be released, and lets staff act without weighing whether the disclosure is permitted. It is short, it is often free, and every hospital and medical practice has a form. Sign one at each provider you use regularly, and sign a standalone one you can carry.

    Do the same for other information-holders. Insurers, pharmacies, and long-term care facilities each maintain their own authorization process. And keep the list current: an authorization naming a former partner is worse than none, because staff will follow it.

    How are these documents signed and where should they live?

    Execution formalities vary by state and matter more than the wording. A document that says exactly the right thing but was signed without the witnesses your state requires can be refused.

    • Capacity. The signer must understand what they are signing. This is why these are done early, not during a hospitalization.
    • Witnesses. Most states require one or two adult witnesses for health care documents, and many disqualify anyone who is the named agent, a treating provider, or an heir.
    • Notarization. Financial powers of attorney are commonly notarized and sometimes must be, particularly if they will be recorded against real estate.
    • Recording. A power of attorney used for real estate transactions may need to be recorded with the county land records office.
    • Copies. Give one to your agent, one to your primary provider, and keep one somewhere accessible rather than in a safe deposit box only you can open.

    Where a signature must be acknowledged, the limits of what a notary can do are worth understanding before you pay for one, because a notary confirms identity and signature but does not confirm that a document is legally sufficient. That distinction, and when a remote online notarization is accepted, is covered in notarization, remote notarization, and what a notary cannot do.

    Worth knowing

    Financial institutions frequently refuse powers of attorney they consider too old, too broad, or not on their own form. Many states have statutes penalizing unreasonable refusal, but arguing the point takes time you may not have. Ask each bank and brokerage now whether they will accept your document, and complete their internal form as a backup.

    What happens if nobody signed anything?

    Someone goes to court. When an adult loses capacity without having named an agent, the only way to obtain authority is a guardianship or conservatorship proceeding, in which a judge appoints a decision-maker after a hearing.

    It is a poor substitute in every respect. It costs money for filings, evaluations, and usually lawyers. It takes weeks at best, while bills go unpaid and treatment decisions wait. It is a public proceeding, so a private medical situation becomes part of the court record. The judge decides who is appointed, and family members who object are entitled to be heard, which means an unmarried partner can be displaced by a relative who has not been present for years. And the appointed guardian often faces ongoing court supervision, including accountings and permission requests for significant decisions.

    Meanwhile, in the absence of a proxy, medical decisions fall to a statutory list of surrogates. That list typically runs spouse, adult children, parents, siblings, and then other relatives. Unmarried partners appear on some state lists in a low position and are absent from others entirely. If your partner is the person you want deciding, the only way to be sure is to say so in a signed document.

    What keeps these documents from failing when you need them?

    Maintenance, mostly. The documents themselves rarely fail; the surrounding facts change and nobody updates them.

    Review the named agents after any significant change in the relationship. A separation does not automatically revoke a power of attorney in every state, and a former partner holding financial authority is a serious exposure. Revoke in writing, notify every institution that has a copy, and destroy the outdated originals. Where a marriage ends, some states revoke a spouse's appointment automatically, but relying on that when the fix takes ten minutes is a bad trade.

    Check that the documents still match the assets. A power of attorney drafted before you bought a business or a rental property may not grant the specific powers those require, and many states insist that certain authorities, such as making gifts or changing beneficiary designations, be stated expressly. Confirm that beneficiary forms on retirement accounts and life insurance still name the right person, since those override a will entirely.

    Finally, tell your agent where everything is and what you would want. A document that nobody can find does no work. If you are married, keep a certified copy of the marriage certificate with these papers, because some institutions will still ask for it, and the way agencies verify marital status is described in how marriages are recognized across state and national borders.

    What to remember

    1. Capacity is the gate: every one of these documents must be signed before the crisis, never during it.
    2. A health care proxy covers decisions while a HIPAA authorization covers access to records, and you need both.
    3. A durable financial power of attorney survives incapacity; an ordinary one does not, which defeats the purpose.
    4. Marriage supplies default medical standing in most states but does not supply authority over separate accounts.
    5. The alternative to these documents is a guardianship case, which is public, slow, and expensive.

    Other questions people ask

    Will a hospital accept a document signed in another state?

    Usually yes. Most states honor an advance directive validly executed elsewhere, and hospitals are generally willing to follow a clear document rather than argue about formalities. Problems arise with unusual formats or missing witness signatures. If you move or spend long periods in another state, signing a version that meets that state's rules removes the argument.

    Can a partner get information from a bank without a power of attorney?

    Not for an account they do not hold. Banks disclose account information only to account holders and to agents named in a power of attorney the bank has accepted. Some institutions require their own form in addition to yours. Ask each institution what it accepts before you need it, because acceptance is decided at the counter.

    What is the difference between a living will and a health care proxy?

    A living will states what treatment you want or refuse in specified circumstances. A health care proxy names a person to decide when circumstances arise that you did not anticipate. The proxy is more flexible because no document can predict every scenario. Most people should have both, kept consistent with each other.
