The law at least in California is that you can use any name you want so long as it is not for the purpose of committing fraud. Go to DMV and get a new driver's license. Take your marriage certificate with you. Contact Social Security to make a name change. You should be OK. If that doesn't work you can file an action with the court for a name change but you certainly don't have to get married again. Good luck.
