Can I change back to my maiden name without a divorce?

Yes, adults can change their names at will--it's a matter  of filing out the correct paperwork, but nothing more. There is no requirement for a change in life or marital status. If you do a Google (or equivalent search) for "name change florida" or a similar search phrase, you'll be able to find forms and directions. Remember that there a great many complexities to this: you have to think about bank accounts, insurance policies, other benefits, paychecks or direct deposit, driver's licenses, credit cards, etc. If you remember all the people and businesses you had to notify when you took your husband's name and all the hoops you had to jump through, it will be like, but possibly worse-while you *can* legally change your name without divorce, people won't expect you to, so you'll probably have  extra explaining to do.

Most states follow what is known as the "common law" rule that you can use any name you want as long it is used continuously without "intent to defraud."  So theoretically you can start using your maiden name again as long as you do so on a regular and consistent basis and without intending to avoid creditors or for some other fraudulent reason. Many states allow a Woman to legally use either name during the course of their marriage.  I am not sure if Florida is one of those states but I would say yes you can and then when the divorce is final it will be finally done.  Good luck.
