Simply fill out your marriage license application and indicate the name each party will use when the marriage is conducted to alter your name. Your marriage certificate, once issued, acts as proof of your name change. You may also submit a petition with the county clerk's office stating that you want your names changed. If you remarry, then your new spouse can request that your former surname be restored. The process is exactly the same as changing your name for the first time. The best way to change your name is by filing some forms with the county clerk's office. They will need copies of your divorce decree or legal separation agreement, which should include the name you wish to have listed on all future documents as well as on your driver's license and other identification cards. A court order is required if one of you has a different last name already. The clerk can advise you on any additional documentation that may be needed. Name changes are useful if you get divorced, separate from your husband or wife, remarry and so on. If you just move away or decide that your married name no longer fits you, you can get a new ID card with your new name on it. Name changes are easy to obtain in Oregon. Simply go to the county clerk's office and follow their instructions.
