A New York bank generally must honor a properly executed statutory short form power of attorney unless it has “reasonable cause” not to. After you present the original or an attorney-certified copy, the bank has 10 business days to do one of three things: honor it, reject it in a written statement of reasons sent to the principal and the agent, or ask you for an agent’s affidavit. Refusing only because the document is not the bank’s own form is not a valid reason.
Can a New York bank refuse a power of attorney?
Only with reasonable cause. Section 5-1504 of the General Obligations Law says no third party doing business in New York may refuse, without reasonable cause, to honor a properly executed statutory short form power of attorney. The law lists what counts as reasonable cause and what does not.
| Situation | Reasonable cause to refuse? |
|---|---|
| The agent will not provide an original or an attorney-certified copy | Yes |
| The bank, in good faith, refers the matter or reports to adult protective services | Yes |
| It knows or reasonably believes the principal has died, or is incapacitated and the power is not durable | Yes |
| Fraud, duress or undue influence is suspected | Yes |
| The bank has actual notice that the power was revoked or ended | Yes |
| The document is not the bank’s own form | No, if that is the only reason |
| Time has passed since the document was signed | No, if that is the only reason |
| There is a time gap between the principal’s and the agent’s acknowledgments | No, if that is the only reason |
The statute lists ten reasonable-cause situations in all. One more limit is worth knowing: the law does not make a bank accept a form that is not a statutory short form power of attorney. A custom document drafted by a lawyer may be accepted, but the bank is not required to.
What must the bank do within 10 business days?
The clock starts when you present the document. The three possible responses come with their own follow-up deadlines:
| The bank’s response | What it must do | Next deadline |
|---|---|---|
| Honor the power of attorney | Accept it and let the agent act | None |
| Reject it in writing | Send a written statement of reasons to the principal and the agent, for example nonconforming form, missing or wrong signature, invalid notarization or unacceptable identification | After a written response from you, the bank has seven business days to honor it or issue a final written rejection |
| Ask for the agent’s affidavit | Require an acknowledged affidavit that the power is still in effect | Seven business days after a compliant affidavit to honor it, unless reasonable cause exists |
These time limits do not apply to the Department of Audit and Control, state public retirement systems, or the Department of Health and social services districts that run Medicaid and other public health insurance. The law also lets a bank rely on the agent’s certification on factual matters, and ask for an opinion of counsel on legal matters if it states the reason in writing.
What makes a New York power of attorney valid?
Under section 5-1501B, a statutory short form must be signed and dated by the principal while they have capacity, or by someone else in the principal’s presence and at their direction who is not the agent. The principal’s signature must be acknowledged, as for a real property deed, and two witnesses must watch the signing. The witnesses cannot be named as agents or as permissible gift recipients. The agent also signs, with an acknowledged signature. The print must be at least 12-point, and the wording must substantially follow the statutory “Caution to the Principal” and “Important Information for the Agent.”
The power usually takes effect when the agent’s signature is acknowledged. If it is written to start later, or upon an event, it takes effect only after that date or event. Before you go to the bank, check three things on your parent’s document: both signatures are notarized, two witnesses signed, and the powers include banking. That last item matters because the form has the principal choose which areas of authority the agent holds.
What can an agent do with a parent’s bank account?
The banking-transactions power in section 5-1502D lets the agent keep, change, close and move money in and out of existing accounts, open new accounts in the principal’s name, use a safe deposit box, write and sign checks, withdraw funds, and receive bank statements. It also covers endorsing checks, taking overdrafts or signing notes, and paying or contesting taxes.
There is a limit. Without express authorization in the Modifications section of the form, or in a separately signed and acknowledged document, the agent cannot add or remove joint account holders or change the beneficiary of a Totten trust account. Separately, the “Important Information for the Agent” in the statutory form says not to use the principal’s assets to benefit yourself or others, or to make gifts, unless specifically authorized.
How do you use the power of attorney at the bank? Step by step
- Call the branch or the bank’s legal department first. Ask what they need to see and whether they want to review a copy before your visit.
- Bring the original or an attorney-certified copy, plus your own photo ID. A bank may have reasonable cause to refuse if you will not provide the original or a certified copy.
- Write down the date you presented it. The 10-business-day period counts from presentation, so ask for a written acknowledgment of receipt.
- Be ready to sign an agent’s affidavit. The law says requiring an acknowledged affidavit that the power is in effect is not unreasonable. It states that you know of no revocation or termination, no modification affecting the transaction, and, if you are a successor agent, that the prior agent can no longer serve.
- Sign as agent. The statutory form says to sign the principal’s name followed by your signature and “as Agent.”
- If rejected, read the reasons. If a defect can be fixed, fix it and respond in writing. The bank then has seven business days to honor it or give a final written rejection.
What are your duties as the agent?
Being named an agent creates a fiduciary relationship. Section 5-1505 requires the agent to act as a prudent person dealing with another’s property, follow the principal’s instructions or, if there are none, act in their best interest, and avoid conflicts of interest.
- Keep the principal’s money separate from yours, except for property the two of you already owned jointly when the power was signed.
- Do not pay yourself or make gifts to yourself unless the document specifically allows it.
- Keep records of all receipts, disbursements and transactions. Within 15 days of a written request, you must provide them to listed parties, including a monitor, co-agent, successor agent, certain government entities or a court evaluator.
- Expect personal liability if you violate these duties or act outside your authority.
A practical habit: keep every receipt and a simple running ledger from day one, and put your parent’s care costs on it. If a sibling asks questions years later, the answer is already written down.
When does a power of attorney end?
Under section 5-1511, it ends when the principal dies, when the principal revokes it, if the principal becomes incapacitated and the power is not durable, or when a court order revokes it, among other events. An agent’s authority also ends on the agent’s death, incapacity or resignation, or on divorce from the principal unless the document says otherwise. Signing a new power of attorney does not by itself revoke an earlier one. Revocation should be a signed, dated document delivered to the agent, and you should tell the bank in writing. A bank that acts in good faith without actual notice is protected.
What if the bank still says no?
Ask for the refusal in writing, then talk to an elder law attorney. Section 5-1510 allows a special proceeding in court to compel a bank to accept the power of attorney, and under 5-1504 the court may award damages, including reasonable attorney’s fees and costs, if the bank acted unreasonably. That special proceeding is the exclusive remedy for a violation. It is a last resort, so fix the document first if the bank’s written reasons point to a real defect.
Paying for a parent’s care from their account
Many agents first use the power of attorney to pay home care bills. The form is not a health care decision-maker: its own caution says the agent cannot make health care decisions, which are handled by a separate health care proxy. For guardianship and the difference between the two, see our guide to power of attorney and guardianship in New York. For costs, see the cost of home care in New York. If your parent may apply for Medicaid, get legal advice before moving or gifting money, and read about Medicaid spend-down.

Frequently asked questions
Can a New York bank refuse a power of attorney?
Only with reasonable cause. Examples include the agent refusing to provide an original or attorney-certified copy, suspected fraud or undue influence, or actual notice that the power was revoked. Refusing only because it is not the bank’s own form is not reasonable.
How long does a bank have to accept a power of attorney in New York?
Ten business days after you present the original or an attorney-certified copy. In that time it must honor it, reject it in writing with reasons, or request the agent’s affidavit.
Does my parent’s POA need to be notarized and witnessed in New York?
For a statutory short form, yes. The principal’s and the agent’s signatures must be acknowledged, and two witnesses who are not named as agents or gift recipients must watch the principal sign.
How should I sign checks or documents as agent?
The statutory form says to sign the principal’s name followed by your signature and “as Agent.”
Can I add myself to my parent’s joint account using the POA?
Not unless the document expressly authorizes it. Without that, the agent cannot add or remove joint account holders. Gifts to yourself also need specific authorization.
Does a power of attorney work after my parent dies?
No. A power of attorney ends when the principal dies. After that, the estate’s legal representative handles the accounts. Tell the bank right away.
