The most common reason couples make a second trip to the clerk's office is showing up without the right documents. Here's exactly what to bring, for both Kentucky and Ohio, so you walk out with your license the first time.

Required for Both States

1. Valid Government-Issued Photo ID — Both Applicants

Both people must bring their own photo ID. One person's ID cannot cover two applicants. Acceptable forms:

  • Driver's license (must be current — not expired)
  • State-issued ID card
  • U.S. passport or passport card
  • Military ID

Expired IDs are not accepted. If your license expired last month, renew it or bring a passport.

2. Social Security Number — Both Applicants

Kentucky and Ohio both require your Social Security number on the marriage license application. You don't always need to present the physical card — many clerks accept the number from memory — but if there's any doubt, bring the card. A mismatch between what you say and what's on file will slow things down.

The thing people forget: Social Security number. Not the card — just the nine-digit number. Most people know their own but can't remember their partner's. Figure this out before you leave for the office, not while standing at the counter.

3. Payment

Fee amounts by area:

  • Kentucky county clerks (NKY): $35.50 — cash or check is reliable; card acceptance varies by office
  • Hamilton County OH Probate Court: $60 — cash, card, or money order
  • Warren County OH: $50
  • Clermont County OH: $55

Cash is always accepted. If you want to pay by card, call ahead — not every Kentucky county clerk processes cards on every day.

4. Both Applicants Present in Person

This isn't a document, but it's a hard requirement: both people must be physically present. You cannot apply on behalf of your partner, and you cannot send a representative. No exceptions in either state.

If Either Applicant Was Previously Married

Both Kentucky and Ohio will ask whether either applicant has been married before, and if so, how that marriage ended. Be prepared with:

  • Final divorce decree — the signed court order, not the initial filing. The date on the document matters.
  • Death certificate — if your previous spouse died
  • Annulment order — if the prior marriage was legally annulled
Common mistake: Bringing the divorce filing receipt instead of the final decree. The filing date and the final decree date are often months apart. Clerks want the final signed order — the one that says "FINAL DECREE OF DISSOLUTION" or equivalent. If you can't find it, your county court clerk's office can provide a certified copy.

Ohio Probate Courts are more likely than Kentucky county clerks to ask for the document upfront. In Kentucky, the clerk may record what you say verbally — but having the paperwork eliminates any ambiguity.

Helpful But Not Always Required

  • Birth certificate — not typically required for adults 18+, but useful if there's a question about your age or if your ID doesn't reflect your legal name after a prior name change
  • Social Security card — useful backup if you don't know your number by heart
  • Your current address — you'll be asked to provide this on the application; know your full address including zip code
  • Parents' names and birth states — some offices (particularly Ohio) ask for this on the application form; know your parents' full names and the states where they were born

What You Don't Need

  • Proof of residence — neither state requires you to live in the county or even the state where you apply
  • Blood test results — no longer required in either Kentucky or Ohio
  • Witnesses — you don't need witnesses to apply for the license (witnesses may be required at the ceremony itself, depending on your officiant)
  • Your partner's ID — you each need your own
