In most states, there is no minimum age for notarizing a minor’s signature. What matters is whether the child can be properly identified and whether they understand what they’re signing and are doing it voluntarily. A notary who’s satisfied on both counts can proceed; a notary who isn’t should refuse. The practical complications, acceptable ID for someone without a driver’s license, when a parent needs to be in the room, how passport consent forms work, are where families actually get stuck.
Capacity Is the Real Threshold
No widely adopted notary statute sets a specific birthday as the cutoff for having a signature notarized. What determines whether a minor can participate is legal capacity: whether the signer understands the document’s purpose and is signing willingly.
A notary evaluating a minor’s capacity typically asks open-ended questions. Can the child explain what the document does? Do they know why they’re signing it? Are they acting on their own, or does something feel off? If the minor can’t answer coherently or shows signs of being pressured, the notary should refuse the service. Many state laws explicitly authorize notaries to decline a notarization when they’re not satisfied the signer is competent or acting voluntarily.
This matters because a minor’s signature on a contract is generally voidable, meaning the minor can later disaffirm the agreement and walk away from it. The voidability doesn’t invalidate the notarization itself, but it’s part of why notaries take extra care here. A notary who proceeds despite obvious signs that the child doesn’t understand what’s happening risks administrative penalties, loss of commission, or civil liability if someone is harmed by the flawed notarization.
Signature by Mark
Very young children or those who cannot write their name may sign using a mark, typically an “X.” Several states allow this but require one or more witnesses to be present when the mark is made. A common practice is for one of those witnesses to print the child’s name next to the mark. Witness requirements differ by state, so check local rules before relying on this option.
When a Notary Should Refuse
A notary who believes a minor lacks capacity should refuse the notarization and note the refusal in their journal. The refusal itself is not a legal problem for the notary. Proceeding when red flags are present is. Common grounds for refusal include a minor who cannot communicate the document’s purpose, visible signs of coercion from an accompanying adult, or a child who seems confused about what they’re agreeing to.
Proving the Minor’s Identity
The biggest practical hurdle is identification. Most teenagers don’t have a driver’s license, and younger children almost never have government-issued photo ID. Notaries generally accept a U.S. passport or a state-issued identification card. A few states also accept military dependents’ ID cards. School IDs, despite being common, are not acceptable for notarization in most jurisdictions.
Rules on expired identification vary. Some states require the ID to be current. Others accept recently expired documents if they were issued within a certain window. There is no universal five-year rule, despite what some guides suggest. If you’re planning a notarization for a child without a passport, applying for a state-issued non-driver ID card or a passport well in advance usually solves the problem.
Credible Identifying Witnesses
When a minor has no acceptable photo ID at all, many states allow one or two credible identifying witnesses to vouch for the signer under oath. Depending on the state, the witness must either be personally known to the notary or present their own valid government ID. The notary administers an oath compelling the witness to swear they know the signer. A witness who lies under that oath commits perjury, which under federal law carries a potential sentence of up to five years in prison.1Office of the Law Revision Counsel. 18 USC 1621 – Perjury Generally
The notary records the witness’s name, address, and the type of ID they presented. Not every state requires a formal journal, but keeping one is best practice, and states that mandate journals typically require these witness details.
When a Parent Needs to Be There
Whether a parent needs to be present depends on the child’s age, the document, and the state. Many jurisdictions expect a parent or legal guardian to accompany a minor during notarization, both to confirm the child isn’t being coerced and to provide an additional identity reference. Some documents, particularly travel consent forms and medical authorizations, require both the minor’s signature and a parent’s signature.
When a parent is present, a careful notary will direct the capacity questions to the child, not the parent, and watch for signs that the adult is answering for the child or applying pressure.
Representative Signatures for Very Young Children
When a child is too young to sign at all, a parent can sign as a representative. The parent signs their own name, usually adding a designation like “as parent and natural guardian of [child’s name].” The notary then notarizes the parent’s signature, not the child’s. To do this, the parent must present proof of the relationship. A birth certificate listing the parent is the most common form of proof, though court-issued custody orders or guardianship papers also work. The parent’s identity is verified using the same ID standards as any other signer.
When Only One Parent Appears
When one parent appears and the document normally requires both parents’ consent, the appearing parent must provide evidence of sole legal custody. Acceptable proof includes a court order granting sole custody, a birth certificate listing only the appearing parent, or a notarized written consent from the absent parent accompanied by a copy of that parent’s ID. Without one of these, the notary should decline.
Passport Consent Forms for Children Under 16
By far the most common reason families need a notarization involving a minor is a passport application. For children under 16, the State Department requires both parents or guardians to appear in person when submitting the application. When one parent cannot attend, that parent must complete Form DS-3053, a Statement of Consent, and have it notarized.2U.S. Department of State. Apply for a Child’s Passport Under 16
The absent parent signs DS-3053 in front of a notary public or passport acceptance agent. The notary cannot be related to the person signing. The parent must present valid government-issued photo ID to the notary and attach a clear photocopy of both the front and back of that ID to the form.3U.S. Department of State.

A few details trip people up. The notarized consent expires 90 days after signing, so timing matters. If the consent lapses before the application is submitted, a new form must be signed and notarized. For parents living abroad, DS-3053 may need to be notarized at a U.S. embassy or consulate rather than by a local foreign notary.3U.S. Department of State.

If neither parent can appear with the child, both parents must submit notarized consent, and a third party such as a grandparent can present the application with the child. That third party needs a notarized statement from both parents granting permission, plus copies of both parents’ photo IDs.2U.S. Department of State. Apply for a Child’s Passport Under 16
Emancipated Minors
An emancipated minor sits in a different legal category. Once a court grants an emancipation decree, the minor gains many of the legal rights of an adult, including the ability to enter contracts and sign documents without parental consent. From a notary’s perspective, an emancipated minor should be treated essentially like an adult signer.
The practical challenge is proving the emancipation. The minor should carry a certified copy of the emancipation decree, meaning a copy bearing the court clerk’s official stamp verifying it’s authentic. Notaries aren’t typically trained to evaluate court orders, so if the document looks legitimate, bears the court’s seal, and the minor can produce valid ID, the notarization can proceed. Obtaining several certified copies from the court clerk in advance is worth the effort, since you’ll likely need them repeatedly.
Can a Minor Use Remote Online Notarization
As of 2024, at least 47 states and the District of Columbia have enacted laws permitting some form of remote online notarization, where the signer appears via a live audio-video connection rather than in person. The rules for RON sessions generally mirror in-person requirements: the signer must be identified, must show awareness and willingness, and the session is typically recorded.
Whether a minor can use RON depends on the state’s specific statute. Some RON laws don’t address minors explicitly, which means the same capacity and identification rules apply as in a face-to-face setting. The State Department accepts electronically notarized passport consent forms where RON is legal in the notary’s state.2U.S. Department of State. Apply for a Child’s Passport Under 16
What It Costs
Notary fees are set by state law and the range is wider than most people expect. Per-signature fees for standard notarial acts like acknowledgments and jurats run from as low as $2 in some states to $25 in others. A handful of states set no maximum fee at all. Mobile notaries who travel to your location charge additional travel fees that can easily exceed $50, and those travel charges are usually unregulated. If both parents are signing a passport consent form, the per-signature fee applies to each signature separately.
