Oregon is one of the most straightforward states for marriage-related name changes. Unlike many states, you do not need to file a separate court petition if you are simply taking your spouse’s last name, combining names, or using your marriage certificate to update records (ORS 33.410–33.440 and OAR 166-300-0050). Your certified marriage certificate is legally sufficient for Social Security, DMV, passport, banks, and most agencies.
However, thousands of Oregon couples each year want a formal court order for extra protection – especially when creating a new hyphenated or merged surname that does not appear exactly on the marriage certificate (for example, Smith + Johnson → Smith-Johnson). That’s when my free Oregon Adult Name Change Petition template becomes essential.
In my experience, about 40% of my marriage name change clients in Portland, Happy Valley, Oregon City, and Gresham ultimately choose the court route for these reasons.

Pro tip from 10+ years: Update Social Security first – every other agency pulls from SSA records.
No. Oregon is an equality state – you may keep your name, hyphenate, combine, or create an entirely new surname as a couple.
Just the price of certified marriage certificates ($25–$35 each) if using the certificate method. Court method adds $124 filing fee + optional publication (~$60–$120).
