Establish legal residence in Oklahoma. Obtaining an Oklahoma driver's license or signing a lease can help you prove that you are an Oklahoma resident. You must have resided in Oklahoma for at least 30 days to petition for a name change.
Assemble a list of your creditors. Some Oklahoma courts require you to submit this list to the court clerk to obtain a name change. If you are in doubt as to whether this is required, ask the court clerk of the county court in the county of your residence.
Complete a name change petition. Although the Oklahoma state government website does not offer a name change petition for download, some websites have them available for sale. Alternatively, you may draft your own petition. It must include your current name, your address, a statement of how long you have lived in Oklahoma, your desired new name, an explanation of the reasons for changing your name and a statement that you are not seeking a name change for any fraudulent or illegal purpose or to evade debts. It must also include a statement in which you confirm that the contents of your petition are true to the best of your knowledge and belief.
Sign and date your name change petition in the presence of a notary public.
File your name change petition with the county court in your county of residence. Include a certified copy of your birth certificate, a list of your creditors (if required) and the filing fee. The filing fee is set by the local court. The court will set a hearing date and notify you.
Publish a public notice of your petition in a newspaper in general circulation in your county. The newspaper must be authorized to publish legal notices. Your notice must include the case name and number, the time and location of the hearing and a statement that anyone may file a written objection to your petition before the hearing. You must publish the notice at least ten days before your hearing is scheduled. You only need to publish it for one day.
Attend your name change hearing. If it is approved, the court will make a copy of the court order available to you.
Replace your identity documents, such as your driver's license and Social Security card, using a copy of the court order as evidence of your new name.
