Yes, a power of attorney can use a credit card belonging to the principal, but only when the POA document grants authority over financial accounts and every charge directly benefits the principal. The agent steps into the principal’s shoes for financial management, not into the principal’s wallet for personal spending. Get that distinction wrong and you’re looking at civil lawsuits, criminal charges, or both.
Does the POA Actually Grant Credit Card Authority
A power of attorney is only as broad as the document says it is. A POA that grants “general authority over banking and financial transactions” typically covers credit cards. A narrower POA that limits the agent to paying specific bills or managing a single bank account might exclude credit card use entirely.
More than 30 states have adopted some version of the Uniform Power of Attorney Act, which includes a provision specifically authorizing agents to “apply for, receive, and use credit and debit cards” when the POA grants general authority over banks and financial institutions. Even in states that haven’t adopted the model law, most broadly drafted POAs cover credit card transactions. Read the actual document. Look for language about financial institutions, credit accounts, or borrowing authority. If it’s not there, you probably don’t have the power to swipe the card.
The type of POA matters too. A durable POA remains in effect if the principal becomes incapacitated, which is usually the whole reason it was created. A non-durable POA expires once the principal can no longer make their own decisions. A springing POA activates only when specific conditions are met, such as a doctor certifying incapacity. If you’re relying on a springing POA, you’ll need proof the triggering event has occurred before anyone will let you use the card.
What You Can Charge on the Principal’s Card
Legitimate use covers expenses that directly benefit the principal and fall within the scope of the POA. In practice, that means maintaining the principal’s established standard of living and covering their ongoing obligations.
- Household necessities: groceries, clothing, personal care items, and prescription medications.
- Recurring bills: utility payments, insurance premiums, medical copays, and property taxes.
- Home maintenance: plumbers, landscapers, and repairs to the principal’s property.
- Medical expenses: doctor visit copays, pharmacy charges, medical equipment, and in-home care costs.
The through-line is simple. Would the principal have spent this money if they were handling their own affairs? If yes, you’re probably on solid ground. If you find yourself rationalizing the charge, that’s a warning sign.
Agents sometimes pay for the principal’s expenses out of pocket first and then want to reimburse themselves. That’s allowed, but it requires careful documentation. Keep every receipt, note the date and purpose of each expense, and record the reimbursement as a clearly labeled transaction. Don’t charge something personal to the principal’s card and call it a reimbursement after the fact. The paper trail matters enormously.
What You Cannot Charge
Any transaction that benefits you rather than the principal is a breach of fiduciary duty. The law calls this self-dealing, and it doesn’t require bad intent. Even agents who plan to “pay it back later” are violating their legal obligations.1Consumer Financial Protection Bureau. Managing Someone Else’s Money: Help for Agents Under a Power of Attorney
Clear violations include:
- Buying personal items for yourself or your family members.
- Paying your own bills, rent, or loan payments.
- Booking personal travel or entertainment.
- Taking cash advances for your own use.
- Making purchases you benefit from, even indirectly, such as buying a car “for the principal” that you primarily drive.
Loyalty runs deeper than avoiding obvious theft. You have to keep the principal’s money completely separate from your own. Don’t commingle accounts, and don’t blur the line between their expenses and yours.1Consumer Financial Protection Bureau. Managing Someone Else’s Money: Help for Agents Under a Power of Attorney
Gifts Are Off Limits Unless the Document Says Otherwise
Making gifts from the principal’s assets, including charging charitable donations or birthday presents to their credit card, is generally prohibited unless the POA document expressly authorizes it. This catches many agents off guard. If the principal always gave $100 to a grandchild for holidays, the agent might assume the tradition should continue. Without explicit gifting authority in the POA, doing so is technically a breach of duty.
When a POA does authorize gifts, they should be consistent with what the principal would have wanted and must not jeopardize the principal’s financial security. Gifts above the federal gift tax annual exclusion (currently $19,000 per recipient for 2026) can also create tax reporting obligations.2Internal Revenue Service. What’s New — Estate and Gift Tax
Getting the Credit Card Issuer to Accept the POA
Having a valid POA and getting a card issuer to honor it are two different experiences. Banks and credit card companies are cautious because they worry about fraud, elder exploitation, and their own liability if they allow unauthorized access.
Common reasons an issuer might push back:
- The POA is several years old, and the institution worries it may have been revoked or that circumstances have changed.
- The POA isn’t durable, and the principal is now incapacitated.
- The institution wants its own in-house form and resists accepting outside documents, even where state law prohibits that practice.
- The POA is missing notarization or witness signatures required by state law.
- The institution suspects the agent is exploiting the principal.
Many states have laws that penalize financial institutions for unreasonably refusing a properly executed POA, including potential liability for attorney fees and damages. If you’re getting pushback, bringing a certified copy of the POA, a valid photo ID, and a calm willingness to escalate to a supervisor often resolves things. For ongoing account management, ask the issuer to add the agent to the account on file to avoid repeat hassles.
Authorized User Is Not the Same Thing
Some families skip the POA process for day-to-day purchases by adding the caregiver as an authorized user on the principal’s credit card. The two arrangements are not equivalent. An authorized user gets a card in their own name linked to the account, but they have no legal ownership and no fiduciary obligations. A POA agent has a legal duty to act in the principal’s best interest and can manage a broader range of financial matters beyond one credit card.
If the principal is still competent, adding the caregiver as an authorized user is often the simplest path for groceries and prescriptions. If the principal is incapacitated or the agent needs broader financial management authority, a durable POA is the right tool. Many families use both.
Records You Have to Keep
An agent has a legal duty to keep records of every receipt, disbursement, and transaction made on the principal’s behalf. This is not optional, and it isn’t something you can reconstruct later from memory. Good records are your best protection if anyone questions a purchase.
For credit card transactions specifically, keep:
- Monthly statements showing every charge.
- Original receipts for each purchase.
- A log noting the date, amount, and specific purpose of every transaction.
- Documentation linking each charge to the principal’s needs.
The CFPB recommends keeping these records organized and available for inspection.1Consumer Financial Protection Bureau. Managing Someone Else’s Money: Help for Agents Under a Power of Attorney Family members, co-agents, or a court-appointed guardian can request an accounting, and in many states the agent must produce records within 30 days of a request.
One practical habit agents overlook: at the register, separate the principal’s purchases from your own into two transactions. It takes an extra minute and eliminates the ambiguity of a mixed receipt that combines your snacks with their prescriptions.
When Your Authority to Use the Card Ends
A POA is not permanent. Your authority to use the principal’s card terminates under several circumstances, and using it after that point creates serious legal liability.
- Death of the principal. A POA terminates the moment the principal dies. The agent has no authority to charge anything after that, even to pay funeral costs or final bills. Those obligations pass to the estate’s executor.
- Revocation. A competent principal can revoke the POA at any time, typically by signing a written revocation and notifying the agent and any institutions holding the document.
- Court order. A court can terminate an agent’s authority if it finds the agent has breached their duties or is otherwise unfit to serve.
- Incapacity, if the POA is non-durable. A non-durable POA expires automatically when the principal loses capacity.
The death scenario is the one that catches people most often. A family member who has managed a parent’s finances for years may not realize that the moment the parent dies, every bit of authority vanishes. Charging the parent’s card the next day for the funeral is technically unauthorized use, even though the intent is perfectly reasonable. The executor handles those expenses.
What Happens If an Agent Misuses the Card
Agents who misuse a principal’s credit card face consequences on two fronts: civil liability and criminal prosecution. Severity depends on how much money was involved and whether the principal was elderly or vulnerable.
Civil Liability
The principal, their family, or their heirs can sue the agent for breach of fiduciary duty. A court can order the agent to restore the full value of whatever was taken, plus interest, and may award attorney fees to the person who brought the lawsuit. Some states allow punitive damages when the conduct was particularly egregious. The agent will almost certainly be removed, and a court may appoint a replacement or a guardian to take over.
Criminal Prosecution
Misusing a principal’s credit card can be prosecuted as theft, embezzlement, or financial exploitation depending on the state. Penalties scale with the amount stolen. Smaller amounts typically bring misdemeanor charges with potential jail time measured in months and fines in the low thousands. Larger amounts, often above $500 to $1,000 depending on the state, can escalate to felony charges carrying potential prison sentences of several years and significantly higher fines.
When the principal is elderly or a vulnerable adult, most states impose enhanced penalties under elder financial exploitation statutes, with stiffer sentences and larger fines than standard theft charges for the same dollar amount. Many states also require financial institution employees to report suspected elder exploitation to adult protective services, so a bank or issuer may flag suspicious transactions before the family notices a problem.
Most agents who get into trouble weren’t scheming from the start. They began with small personal charges they planned to repay, or they gradually stopped distinguishing between the principal’s expenses and their own. Intent doesn’t matter much once the money is gone. Courts look at what happened, not what you meant to happen. If the statements show personal charges, the burden shifts to the agent to explain every one, and “I was going to pay it back” has never been a winning defense.
