An attorney-in-fact affidavit of full force and effect is a sworn, notarized statement in which an agent confirms that the power of attorney they’re using is still valid at the moment of the transaction. Banks, title companies, brokerages, and county recorders routinely require it before they’ll let anyone act for someone else, because the original power of attorney could have been revoked, the principal could have died, or the agent’s authority could have ended in ways the paper itself doesn’t show. Section 119 of the Uniform Power of Attorney Act specifically allows any person asked to accept a power of attorney to request this certification from the agent and rely on it without further investigation.1Mississippi Secretary of State. Uniform Power of Attorney Act More than 30 states have adopted some version of the Act.
What the Affidavit Certifies
The document is built around a set of sworn statements the agent makes under penalty of perjury. Wording varies by state, but the core declarations track the model statutory form and cover the same ground everywhere the Uniform Act has been adopted.
The agent certifies:
- That the principal is alive. Every power of attorney terminates at the principal’s death, including durable ones.
- That the power of attorney has not been revoked and the agent’s authority has not been terminated, to the agent’s knowledge.
- For a springing power, that the triggering event has occurred, most often that the principal has become incapacitated as defined in the original document.
- For a successor agent, that the prior agent is no longer able or willing to serve.
The affidavit also carries the identifying information that ties it to the underlying power of attorney: the full legal names of the principal and agent exactly as they appear on the original, the date the power of attorney was signed, and the jurisdiction where it was executed. If the original was recorded, include the recording reference number so the third party can verify the chain of authority without a separate records search.
Accuracy on these details is not optional. A misspelled name, a wrong date, or a recording number that doesn’t match gives the institution a reason to reject the document and delay the transaction. Transcribe identifying information directly from the original power of attorney rather than working from memory.
How the Type of Power of Attorney Changes What You Certify
The kind of power of attorney behind the affidavit changes what the agent needs to prove.
Durable Powers of Attorney
A durable power of attorney survives the principal’s incapacity, so the agent can continue acting even if the principal can no longer make decisions. The certification is straightforward: the agent swears the principal is alive and the power hasn’t been revoked. The principal’s current mental state is not something the agent has to address, because the power remains valid regardless.
One point that trips people up: “durable” does not mean the power survives death. Every power of attorney ends when the principal dies. Durable only means it survives incapacity. After death, authority passes to the executor or personal representative of the estate.
Springing Powers of Attorney
A springing power sits dormant until a triggering event occurs, usually the principal’s incapacity. The certification adds a layer: the agent must declare that the triggering condition has been met. In practice, that often means attaching a physician’s affidavit or whatever proof of incapacity the original power of attorney defined as sufficient.
Springing powers create real friction at the transaction stage. The third party may want to see the medical documentation, and institutions differ on what they’ll accept. Some states have moved away from springing powers for exactly this reason. If you’re working with one, expect the verification process to take longer and bring supporting documents to the first meeting.
Completing and Notarizing the Affidavit
The agent fills out the form, but it has no legal force until it’s notarized. That means appearing in person before a notary public, not mailing a signed form. The notary verifies the agent’s identity through government-issued ID and administers an oath or affirmation.
For an affidavit, the correct notarial act is a jurat, not an acknowledgment. The difference matters. With an acknowledgment, the notary only confirms that the signer appeared and identified themselves. With a jurat, the notary administers an oath, the signer must sign in the notary’s physical presence, and the notary certifies that the signer swore to the truth of the contents. Because this document contains sworn factual statements, it requires a jurat. Using the wrong notary certificate can render the affidavit legally ineffective.
The finished document needs the notary’s official seal, signature, commission expiration date, and jurisdiction. Missing any of those elements gives the receiving institution grounds to reject it. Check that everything is filled in before you leave the notary’s office.
Scheduling is often the real bottleneck. Some title companies and financial institutions want the affidavit executed within days of closing, so waiting until the last minute to find a notary can create avoidable delays.
Presenting the Affidavit to the Third Party
Most institutions want an original notarized affidavit, not a photocopy. Keep a copy for your records before handing over the original. If you haven’t already provided the underlying power of attorney, the institution will ask for that too; the affidavit supplements the power, it doesn’t replace it. Some practitioners recommend providing a certified copy of the original power of attorney rather than surrendering the original, since you may need it for transactions with other parties.
For real estate transactions, the affidavit typically has to be recorded with the county recorder’s office alongside the deed or mortgage documents. The original power of attorney usually must be recorded as well, or at minimum include recording reference information.
Under the Uniform Power of Attorney Act, once the agent presents an acknowledged power of attorney and the institution requests a certification, the institution generally has seven business days to accept the power, reject it with a valid reason, or request additional items like a certification, translation, or legal opinion. After receiving the certification in satisfactory form, it typically has five more business days to accept or reject. These timelines come from the model act; actual deadlines depend on how your state adopted it.
When a Third Party Won’t Accept the Affidavit
Some institutions drag their feet or refuse outright even when presented with a valid, notarized affidavit alongside the original power of attorney. Banks in particular have a reputation for rejecting powers of attorney based on age, form, or vague policy reasons. The Uniform Power of Attorney Act was written to address these refusals.
Under the Act, a third party that unreasonably refuses to accept an acknowledged power of attorney may face a court order mandating acceptance, liability for damages as if it had refused to deal with the principal directly, and responsibility for the agent’s reasonable attorney’s fees and costs.1Mississippi Secretary of State. Uniform Power of Attorney Act The fees provision gives the threat teeth: an institution that loses doesn’t just have to accept the power of attorney, it has to pay the agent’s legal bills.
Institutions do have legitimate grounds for refusal. They can reject an affidavit if they have actual knowledge the power of attorney has been terminated, if accepting would violate federal law, if the agent refuses to provide a requested certification or legal opinion, or if they have a good-faith belief the principal may be subject to abuse or exploitation by the agent. An institution that reports suspected elder abuse to adult protective services is protected from liability for the resulting delay.
If the affidavit is rejected, the institution must usually provide a written explanation. Common rejection reasons include mismatched names between the affidavit and the power of attorney, missing notary elements, or a form that doesn’t comply with state statutory requirements. Many of these are fixable. If a rejection seems pretextual, citing the relevant section of your state’s power of attorney act in a follow-up letter often changes the institution’s calculation.
Securities Transfers Need More Than a Notary Seal
One area where a notarized affidavit alone is not enough is securities transfers. If the agent needs to transfer stocks, bonds, or mutual fund shares held in the principal’s name, the transfer agent will almost certainly require a Medallion Signature Guarantee in addition to the affidavit. A notary seal will not substitute.
A Medallion Signature Guarantee can only be provided by a financial institution that participates in one of the recognized Medallion programs, such as a commercial bank, brokerage, credit union, or savings association. The guaranteeing institution takes on financial liability for the authenticity of the signature, which is why the securities industry requires it for ownership transfers. Contact the institution holding the securities before preparing documents to confirm exactly what’s needed, since requirements can vary by transfer agent and account type.
Consequences of a False Certification
The affidavit is made under penalty of perjury. Under federal law, anyone who willfully makes a false statement under penalty of perjury faces up to five years in prison, a fine of up to $250,000, or both.2Office of the Law Revision Counsel. 18 USC 1621 State perjury laws carry their own penalties on top of that.
An agent who uses a false affidavit to access someone’s bank accounts or transfer property can also face federal charges for wire fraud, bank fraud, or aggravated identity theft.3Department of Justice. Identifying and Prosecuting Power of Attorney Abuse On the civil side, the principal or their estate can sue for the full amount taken plus damages, and courts routinely impose constructive trusts and disgorgement orders.
Every declaration on the affidavit should be something the agent genuinely believes to be true at the moment of signing. If there is any doubt about whether the principal is alive, whether the power of attorney was revoked, or whether a springing event actually occurred, verify before signing rather than certify and hope.
