What is a surname if you are married?

What Happens to Your Surname When You Get Married?

Getting married doesn’t automatically change your name—despite what some might assume. In most countries, including the United States, Canada, and the UK, both partners can choose what to do with their surnames after the wedding. There’s no legal requirement to change anything. You can keep your birth name, adopt your spouse’s surname, or create a new one together.

One popular option is to take a common surname. If both partners decide to share the same last name, they must agree on the exact form—this means the name must appear in the same order and with the same styling. For example, if one person wants to hyphenate, both must hyphenate. Consistency matters, especially legally. You can’t have “Smith-Jones” on one passport and “Jones-Smith” on another if you’re opting for a shared surname policy.

Another choice is a compound surname, which combines both partners’ last names—often with a hyphen, like “Miller-Clark” or “Clark Miller.” Some couples use this to honor both family lineages, while others prefer it for equality and identity reasons. It’s worth noting that compound names can sometimes complicate paperwork, especially when dealing with government forms that expect a single surname.

Ultimately, the decision is deeply personal. Some people change their names for tradition, others for simplicity, and many choose to keep things exactly as they are. Marriage is about partnership, and your name is just one way to reflect that. Whether you keep your original surname or create a new one together, what matters most is that the choice feels right for both of you.
