The Oklahoma name-change process
Most legal name changes in Oklahoma that aren't tied to a marriage or divorce go through the District Court (Civil). You file where you live — District Court in the county where you have resided for at least 30 days (with 30+ days of Oklahoma domicile). The filing fee is $154–$170 (typical $165, 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 3–8 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 Oklahoma driver's license, then your passport — in that order, because each one checks the last.
