The Wyoming name-change process

Most legal name changes in Wyoming that aren't tied to a marriage or divorce go through the District Court. You file where you live — District Court in the county where you live. The filing fee is $100–$120 (typical $120, varies by county), so confirm the exact amount with your county clerk before you file.

After you file, you publish a legal notice in a newspaper. From filing to a signed order usually takes 8–16 weeks.

Once the judge signs your order, order several certified copies right away — you'll hand one to Social Security, the DMV, and the passport agency, in that order.

After your order: who to notify

The name change isn't finished at the courthouse. Update Social Security first, then your Wyoming driver's license, then your passport — in that order, because each one checks the last.
