Age Requirements

You must meet these age requirements in order to be considered eligible to apply for a marriage license.

  • Legal age for marriage in the State of Idaho for both applicants is 18 years-of-age.
  • Applicants who are 16 or 17 years old must be accompanied by a parent or legal guardian. Parents will need to show an original birth certificate to prove they are able to sign the affidavit; legal guardians must supply a certified copy of their appointment of guardianship. The applicant must present one of the following three items:
    • Current driver’s license
    • Passport
    • State ID card

    Parent or legal guardian must complete the following:

    • Affidavit of Consent to Marriage of Minor

    Parents or legal guardian will need to bring in a State or Federally issued picture ID for the Affidavit of Consent to be notarized.

  • Anyone who is younger than 16 years old cannot obtain a marriage license.
  • Applicants that are more than 3 years apart in age cannot obtain a marriage license if both parties are not 18 years old.

Other Requirements

You must also meet these requirements in order to apply for a license in Idaho.

Blood tests are not required. However, both parties must read and sign the Marriage License Affidavit.

Applicants cannot be first cousins or nearer kin.

A license can be issued one day after the final date of a divorce.

License Conditions

Licenses may be obtained from any county within Idaho and can only be used within the state. You do not need to be a resident of Idaho to use the license. Licenses must be returned to the county in which they were purchased for recording.

There is no expiration date on your marriage license.

Certified Copy

Once the marriage has taken place, the completed marriage license is returned to the County Clerk. Certified copies of marriage licenses will cost $2.00.

Legal Copies
The certified document is considered the legal copy, and can be used by the applicants to change their name on items like a driver's license or social security card.

A non-recorded marriage certificate will be provided. This is not a legal document and may not be used as proof of marriage. If an issued license is lost or destroyed, it can be replaced at the County Clerk’s office.
