An Idaho marriage license is issued by any county recorder’s office in the state, and both applicants must appear together in person with photo ID and Social Security numbers. The fee runs about $28 to $30, and there is no waiting period and no blood test, so you can legally marry the same day you pick up the license. The license is good statewide, meaning you can apply in one county and hold the ceremony in another.
Who Can Apply
If you are 18 or older and unmarried, you can apply on your own with no extra paperwork beyond the application itself.1Idaho State Legislature. Idaho Code Section 32-202 – Persons Who May Marry
Applicants who are 16 or 17 face tighter rules. You need written consent from a parent or legal guardian, notarized and filed with the county recorder. You cannot marry someone 18 or older if the age gap is three years or more. If both parties are minors, each must submit an original or certified copy of a birth certificate. No license is issued to anyone under 16.1Idaho State Legislature. Idaho Code Section 32-202 – Persons Who May Marry
Certain family relationships are barred outright. Marriages between parents and children, grandparents and grandchildren or any ancestor-descendant pairing, siblings of whole or half blood, and uncles or aunts with nieces or nephews carry no legal effect from the moment they occur.2Idaho State Legislature. Idaho Code Section 32-205 – Incestuous Marriages First-cousin marriages are also prohibited in Idaho.
What to Bring to the Recorder’s Office
Bring a valid photo ID such as a driver’s license or passport. Both applicants must provide Social Security numbers on the application.
If you have never been assigned a Social Security number, you will need a letter from the Social Security Administration confirming that, a valid unexpired passport, and proof of lawful entry into the United States such as a visa stamp or I-94 traveler log.3Idaho State Legislature.

The application itself asks for full legal names, current addresses, birthplaces, and the full names and birthplaces of each applicant’s parents. If either of you has been married before, expect to disclose when and how that marriage ended.
The license fee is roughly $28 to $30 depending on the county, and most offices charge about $2 for a certified copy of the recorded certificate. Payment methods vary. Some counties take credit or debit cards; others want cash or check. Call ahead.5Twin Falls County. Marriage Licenses – Twin Falls County
Applying in Person
Both of you must appear together. One person showing up alone will not work, because the office verifies identities and witnesses both signatures in person.4Ada County Clerk.

The license does not expire. You can hold it for weeks or months before the ceremony, though county offices generally suggest applying within a year of your planned wedding date.6Kootenai County, ID. Frequently Asked Questions
Common-Law Marriage in Idaho
Idaho does not recognize common-law marriage formed on or after January 1, 1996. Living together and presenting yourselves as a married couple does not create a legal union; you need both a license and a solemnized ceremony. Common-law marriages established in Idaho before that 1996 cutoff remain valid.7Idaho State Legislature. Idaho Code Section 32-201 – What Constitutes Marriage, No Common-Law Marriage After January 1, 1996
Who Can Perform the Ceremony
Idaho authorizes a defined list of officiants. On the government side, that includes current and qualifying retired justices of the state supreme court, court of appeals judges, district judges, and magistrate judges, along with the current or former governor, the current lieutenant governor, any current mayor, any current federal judge, and current tribal judges or approved tribal officials from an Idaho Indian tribe. Retired judges must be drawing a retirement benefit from the judges’ retirement system or the public employee retirement system for their judiciary service to qualify.8Idaho State Legislature. Idaho Code Section 32-303 – By Whom Solemnized
Any priest or minister of any denomination may officiate. The statute does not distinguish between traditionally ordained clergy and those ordained online, which is why ministers ordained through organizations like the Universal Life Church regularly perform Idaho weddings. Some recorders may ask for proof of ordination, so your officiant should keep credentials handy. Officiants do not have to register with any government office before performing a ceremony.
Filing the Certificate
The ceremony is not the last step. Your officiant must sign the marriage certificate and return it to the county recorder’s office that issued the license within 30 days. Filing late is a misdemeanor, and the officiant can face a fine of $20 to $50.9Idaho State Legislature. Idaho Code Section 32-402 – Certificate and Return
Until the certificate is recorded, your marriage does not appear in the public record, which matters when you need proof for insurance enrollment, tax filing, survivor benefits, or a name change. Once the certificate is processed, you can request certified copies for about $2 each.5Twin Falls County. Marriage Licenses – Twin Falls County Order a few extras upfront.
Changing Your Name
Marriage in Idaho does not automatically change your legal name. If you plan to take your spouse’s last name, the order of updates matters.
Start with the Social Security Administration. You can request a replacement card with your new name online in some cases, or by visiting a local SSA office with your certified marriage certificate. The new card arrives by mail in 5 to 10 business days.10Social Security Administration. Change Name with Social Security
Once Social Security has your updated name, visit an Idaho Transportation Department office to update your driver’s license. Bring your certified marriage certificate, which must show a seal and document number confirming it was recorded. The DMV will not process the name change until Social Security has been updated first.11Idaho Transportation Department.
