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. You need an alternative way to confirm who they are. 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.
Minor Comprehension Requirements
Yes. You cannot notarize for someone who does not comprehend what they are signing, regardless of age. For a minor, this means 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
Most states require a parent or legal guardian to be present when you notarize a minor’s signature, or at minimum to have provided written consent. The parent’s role is to confirm that the minor is signing voluntarily and to provide identification for the child if the minor does not have their own ID.
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.
Frequently Asked Questions
Can a parent sign on behalf of a minor?
No. The minor must sign the document themselves. A parent consents to the notarization, but they cannot sign in the minor’s place on the document.
Does a minor need ID for notarization?
If the minor has a passport or state ID, use it. If not, most states allow a parent to identify the child under oath. Some states accept school IDs. Check your state’s rules.
What documents do minors typically need notarized?
Travel consent letters (when a child travels with one parent), passport applications, name change petitions, school enrollment forms, and medical consent forms.
