Is my daughter's marriage still valid since it contains a last name that is no longer legally her last name?

Question Details: My daughter got married this week. She presented her driver's license at the courthouse at the time of the marriage. However, the last name on her driver's license isn't her legal last name anymore. My husband, her stepdad. legally adopted her a few months ago in another state. Her birth certificate and last name was legally changed but she hasn't gotten around to changing her driver's license or SS card yet. She presented her driver's license, as well as filed out the marriage license application, and signing her marriage certificate, using her old last name which is not her legal last name anymore.
