Yes, a person acting under a power of attorney can use the principal’s credit card, 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. Getting that line wrong can lead to civil lawsuits, criminal charges, or both.
Does Your POA Actually Authorize Credit Card Use
A power of attorney gives the agent only the authority the document spells out. A POA granting “general authority over banking and financial transactions” typically covers credit cards. A narrowly drafted POA limited to paying specific bills or managing a single account may not.
More than 30 states have adopted some version of the Uniform Power of Attorney Act, which specifically authorizes 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 isn’t there, you probably can’t swipe the card.
The type of POA matters too. A durable POA stays in effect if the principal becomes incapacitated, which is usually the whole reason it was created. A non-durable POA ends once the principal can no longer make their own decisions. A springing POA only activates when a specific condition is met, such as a doctor certifying incapacity. If you’re relying on a springing POA, expect to show proof that the triggering event has occurred before any institution lets 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 their established standard of living and meeting their ongoing obligations.
- Household necessities: groceries, clothing, personal care items, and prescription medications.
- Recurring bills: utilities, insurance premiums, medical copays, and property taxes.
- Home maintenance: plumbing, landscaping, or repairs on the principal’s property.
- Medical costs: doctor visit copays, pharmacy charges, medical equipment, and in-home care.
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.
Accepting an appointment as an agent creates a fiduciary relationship, meaning you owe the principal an unusually high level of loyalty and care. Every charge must serve the principal’s interests, not yours. You must keep the principal’s money completely separate from your own, avoid even the appearance of a conflict, and manage their finances with the care a reasonable person would use handling someone else’s property.1Consumer Financial Protection Bureau.

Reimbursing Yourself for Out-of-Pocket Costs
Agents sometimes pay the principal’s expenses from their own funds first and then want reimbursement. That’s allowed, but it requires careful documentation. Keep every receipt, note the date and purpose, and record the reimbursement as its own clear transaction. Don’t charge something personal to the principal’s card and label it a reimbursement after the fact. If anyone later questions the transaction, the paper trail needs to tell the story for you.
What You Cannot Charge on the Principal’s Card
Any charge 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 well-meaning agents who plan to “pay it back later” are violating their legal obligations.
- Personal items for yourself or your family members.
- Your own bills, rent, or loan payments.
- Personal travel or entertainment.
- Cash advances for your own use.
- Purchases you benefit from even indirectly, like buying a car “for the principal” that you primarily drive.
The CFPB’s guide for POA agents uses that last example directly: if you use the principal’s money to buy a car you claim is for driving them to appointments, but mostly use it for your own errands, that’s a conflict of interest even though the original purchase had a legitimate purpose.1Consumer Financial Protection Bureau.

Gifts Are Off Limits Unless the Document Says Otherwise
Making gifts from the principal’s assets, including charitable donations or birthday presents charged to their credit card, is generally prohibited unless the POA expressly authorizes it. This catches many agents off guard. If the principal always gave $100 to a grandchild for the holidays, continuing the tradition may feel natural. Without explicit gifting authority in the POA, it’s still a breach of duty. Where a POA does authorize gifts, they must be consistent with what the principal would have wanted and must not jeopardize their financial security.
Getting the Credit Card Company to Accept the POA
Having a valid POA and getting a financial institution to honor it are two different experiences. Banks and credit card issuers are cautious because they worry about fraud, elder exploitation, and their own liability.
Common reasons for pushback:
- The POA is several years old and the issuer worries it may have been revoked.
- The POA isn’t durable and the principal is now incapacitated.
- The institution insists on its own in-house POA form, even where state law discourages that.
- Notarization or witness signatures required under state law are missing.
- The institution suspects abuse and declines the transaction.
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 hitting resistance, bring a certified copy of the POA and a valid photo ID, and be ready to escalate calmly to a supervisor. For ongoing use, ask the issuer to place the agent on the account’s file so you don’t repeat the process every month.
Authorized User vs. POA Agent
Some families skip the POA process at the register entirely by adding the caregiver as an authorized user on the principal’s card. The two tools do different work. An authorized user gets a card in their own name linked to the account, which makes purchases seamless, but has no ownership of the account and no fiduciary obligations. A POA agent carries legal duties to the principal and can manage a much wider range of financial matters than one credit card.
If the principal is still competent, authorized user status is often the simplest path for day-to-day purchases like 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.
Keep Records of Every Charge
An agent has a legal duty to keep records of every receipt, disbursement, and transaction made on the principal’s behalf. This isn’t optional and can’t be reconstructed from memory a year later.
For credit card use specifically, hold onto:
- Monthly statements showing every charge.
- Original receipts for each purchase.
- A log noting the date, amount, and specific purpose of each 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. In many states, the agent must produce records within 30 days of a request.
A practical habit worth adopting: at the register, ring up the principal’s purchases separately from your own. It takes an extra minute and eliminates mixed receipts where your snacks sit next to their prescriptions.
When Credit Card Authority Ends
A POA isn’t permanent. The agent’s authority to use the card terminates in several situations, and using the card afterward can create serious liability.
- Death of the principal. A POA ends the moment the principal dies. The agent has no authority to charge anything to the card afterward, even to pay funeral costs or final bills. Those obligations pass to the executor or personal representative.
- 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 on file.
- Court order. A court can terminate the agent’s authority after finding a breach of duty or other unfitness to serve.
- Incapacity, if the POA is not durable. A non-durable POA automatically expires when the principal becomes incapacitated.
The death scenario trips people up the most. A family member who has been managing a parent’s finances for years may not realize that the moment the parent dies, every bit of their authority vanishes. Charging the parent’s card the next day for the funeral is technically unauthorized use, even when the intent is entirely reasonable.
What Happens if You Misuse the Card
Agents who misuse a principal’s credit card face consequences on two fronts: civil liability and criminal prosecution. Severity depends on the amount 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 taken, plus interest, and can award attorney fees to the person bringing the suit. Some states also allow punitive damages where the conduct was egregious. The agent will almost certainly be removed, and a court may appoint a replacement or a guardian to take over financial management.
Criminal Prosecution
Misuse can be charged as theft, embezzlement, or financial exploitation depending on the state. Penalties scale with the amount taken. 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 with potential prison terms 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, which carry 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 the bank or card issuer may flag suspicious activity before the family notices anything is wrong.
Most agents who end up in trouble didn’t set out to steal. They started with small personal charges they intended to repay, or gradually stopped drawing the line between the principal’s expenses and their own. Intent carries little weight once the money is gone. If the statements show personal charges, the burden falls on the agent to explain every one, and “I was going to pay it back” is not a defense that works.
