A sudden stroke, a fall, or the slow progress of dementia can leave an older adult unable to pay bills, manage investments, or talk to a bank about a suspicious withdrawal. When that happens, the person’s adult children often assume they can simply step in. In most states, they cannot — not without either a signed legal document naming them in advance or a judge’s order handed down months later.
The Financial Power of Attorney: Authority Signed in Advance
A durable power of attorney is a document an account holder signs while still mentally competent, naming an “agent” who can pay bills, manage investment accounts, file taxes, and handle property on the account holder’s behalf. The word “durable” matters: it means the authority keeps working even after the person who signed it becomes incapacitated, unlike an ordinary power of attorney, which lapses the moment the signer can no longer make decisions. This is generally the fastest and least expensive route to financial help, because the document itself — not a judge — grants the authority.
Because the account holder chooses the agent and can spell out exactly what the agent may and may not do, a bank or brokerage can generally act on the document within days once it is presented, verified, and, in some states, notarized or recorded. No court filing, hearing, or ongoing supervision is required unless a dispute arises, according to the Consumer Financial Protection Bureau’s Managing Someone Else’s Money guide series.

The Fiduciary Duties That Come With the Authority
Signing a power of attorney does not hand an agent a blank check. The CFPB’s guide for agents describes the role as a fiduciary duty with four core obligations: acting only in the account holder’s best interest, managing the money and property carefully, keeping the account holder’s funds separate from the agent’s own, and keeping detailed records of every transaction. An agent who mixes funds, pays themselves without express authorization in the document, or makes gifts to themselves or other family members that were not clearly intended by the account holder can be removed, sued, or, in cases involving outright theft, referred to prosecutors.
Presenting the document is not always the end of the process, either. A bank or brokerage sometimes refuses to accept a power of attorney it has not seen before, asking the agent to fill out its own in-house form instead, a problem if the account holder has already lost the capacity to sign anything new. The CFPB’s guidance recommends providing certified copies to every institution as soon as the authority is needed, escalating to a supervisor if front-line staff balk, and involving an attorney if the institution still refuses, since state law in many cases requires financial institutions to honor a validly executed power of attorney.
Court-Ordered Guardianship: The Fallback When No Document Exists
When an older adult becomes incapacitated without ever signing a power of attorney, a family member typically must petition a probate or surrogate’s court to be appointed guardian of the property, sometimes called a conservator depending on the state. The CFPB’s guide for this role notes it is reserved for people who have already been appointed by a court and given the legal duty and power to manage another person’s finances. Getting there usually requires medical evidence of incapacity, notice to relatives who may object, and a hearing before a judge decides who serves and under what limits.
Once appointed, a guardian of property does not operate with the same freedom an agent under a power of attorney has. Many states require the guardian to post a surety bond, file an inventory of the parent’s assets, and submit annual accountings to the court detailing every dollar spent — obligations that continue for as long as the guardianship remains open.
The Cost of Waiting Until a Crisis Forces the Issue
Guardianship proceedings carry expenses a signed authorization avoids entirely: attorney fees to file the petition, court filing costs, fees for a court-appointed evaluator to assess capacity, and often an ongoing bond premium tied to the value of the estate being managed. The process can stretch for months, and during that gap, no one has clear legal authority to pay a mortgage, respond to a bank’s fraud hold, or move money out of a struggling investment account. Guardianship filings are also public court records, meaning a family’s financial affairs — and any disagreement over who should be in charge — become part of the public docket rather than staying private.
Disputes are not rare. Adult siblings sometimes disagree about who is best suited to serve, and a contested guardianship can turn into a lengthy and expensive legal fight layered on top of an already difficult family situation.
Putting a Power of Attorney in Place Before It Is Needed
A financial power of attorney only works if it is signed while the account holder still has the mental capacity to understand and execute it — waiting until after a diagnosis or a hospitalization can be too late. The CFPB’s guides recommend naming a trusted agent and, where the law allows, a backup agent, deciding whether the authority takes effect immediately or only upon a doctor’s certification of incapacity, and giving copies of the signed document to the agent, an alternate, and the account holder’s bank or brokerage well before it is ever needed. Reviewing the document periodically, and updating it if a relationship or state of residence changes, keeps it usable when the time comes.
Families who never got the paperwork signed are not without options, but the CFPB’s separate guide for court-appointed guardians and conservators makes clear that route runs through a courtroom, not a signature — a distinction that can mean the difference between managing a parent’s finances within days or waiting months for a judge’s permission.
