How to Sign Your Marriage License in Colorado:
The Surprising Truth
At a recent wedding we officiated, the bride shared something that stopped us in our tracks: the issuing county had told her to sign her new last name on the marriage certificate—and even encouraged her to practice her new signature in advance.
Wait, what?
That advice directly contradicted what we’ve always understood: a marriage certificate is a legal document, and it should be signed using your current legal name, not the one you intend to adopt.
So we started digging.
Here’s what we found:
Summit County told us: “It doesn’t really matter what name you use.”
Broomfield County said: “You cannot sign a name different than what is listed.” (We’ve always found their county attorney to be spot-on when it comes to the letter of the law.)
One other County, who we will reserve naming, meanwhile, states on their website that signing your new name is how you initiate a legal name change—even though that’s not how the legal name change process actually works.
As it turns out, there is no statewide standard. The Colorado Secretary of State doesn’t govern marriage certificates. Each county clerk’s office sets its own rules, and yes, they can contradict each other.
So what’s a couple to do?
**Follow the instructions of the county that issues your license** — to the letter.
Even if a friend tells you “we signed with our new names and it was fine,” their license may have come from a county with entirely different policies.
When in doubt, call the county clerk directly and ask for written guidance. This isn’t a detail you want to guess on—getting it wrong can delay recording or even require you to redo paperwork.
