Yes, you can notarize a minor’s signature. The process is similar to notarizing an adult’s, but there are extra steps around identity verification and parental consent that you need to get right. Here is what to know before you do it.

The Basic Rule

There is no minimum age for notarization in most states. If the person can understand what they are signing and appear before you voluntarily, you can notarize their signature. The same notarial acts apply: acknowledgments, jurats, oaths. The difference is in how you verify identity and whether a parent or guardian needs to be involved.

Verifying a Minor’s Identity

Most minors do not have a driver’s license, so you need an alternative way to confirm who they are — the same acceptable-ID rules apply, just with younger faces. Options include:

• Passport: A U.S. passport or passport card works for any age. If the minor has one, use it.
• State-issued ID card: Some states issue non-driver ID cards to minors. These are acceptable.
• School ID: Some states accept school identification. Others do not. Check your state’s rules.
• Parent or guardian identification: Some states allow a parent to identify their own child under oath. The parent swears to the minor’s identity, and you record the parent’s ID information in your journal.
• Credible witnesses: If the minor has no ID and the parent is not present, some states allow credible witnesses who know the minor to vouch for their identity — see how a credible witness works.

Minor Comprehension Requirements

Comprehension is required at any age: you cannot notarize for someone who does not understand what they are signing. For a minor, you need to be satisfied that they understand:

• What the document is (e.g., “this is a letter giving your other parent permission to take you to Mexico”)
• That they are signing it voluntarily
• That they are not being pressured by anyone in the room

You do not need to explain the legal consequences of the document. That is a lawyer’s job. You just need to confirm the minor is aware of what they are doing.

Parental Consent

Here is the honest state of the law: most states impose no blanket parental-presence rule for notarizing a minor, and the ones that address minors at all usually do it through document-specific rules or through the practical reality that a minor with no ID needs a parent anyway. The parent’s real function is confirming the child is signing voluntarily and identifying the child when the minor has no ID of their own. Schools, courts, and airlines drive the stricter practice — a travel consent letter or passport application often needs a parent’s notarized signature regardless of what notary law says. The safe default: have a parent or guardian present, and if your state’s handbook says nothing about minors, that presence solves both the identity and the voluntariness question in one step.

Document the parent’s presence in your journal. Record the parent’s name, their relationship to the minor, and how you verified the parent’s identity.

Common Documents for Minor Notarizations

• Travel consent letters: When a child travels with only one parent, airlines and immigration authorities often require a notarized letter from the absent parent consenting to the trip.
• Passport applications: Both parents typically need to sign a child’s passport application, and those signatures may need to be notarized if one parent cannot appear in person.
• Name change petitions: Court procedures for changing a minor’s name often require notarized consent from both parents.
• School enrollment forms: Some private schools require notarized enrollment documents.
• Medical consent forms: When a child is staying with a non-parent (grandparent, family friend), a notarized medical consent form authorizes that person to seek treatment.

What to Record in Your Journal

• The minor’s name and age (or date of birth)
• How you verified the minor’s identity (parent oath, passport, school ID, etc.)
• The parent or guardian’s name and relationship to the minor
• How you verified the parent’s identity
• Type of notarial act performed
• The document type (e.g., “travel consent letter”)

When to Decline

Decline the notarization if:

• The minor clearly does not understand what they are signing (very young children, for example).
• The minor appears to be under pressure from a parent or guardian. If a parent is telling the child “just sign it” and the child looks uncomfortable, stop.
• You cannot verify the minor’s identity through any acceptable method.
• No parent or guardian is present and your state requires one.
