I agree with Attorney Johns. Additionally, you should know that, if necessary, changing your name under circumstances you described is a simple process. You can pick up a form at your county's department of court records and pay a small filing fee. That should be all there is to it.
I also agree with the previous responders. I would call and ask. If it is an issue, speak with a local attorney or go to the prothnotary or law library. Any of those resources will help you with this matter if it does infact have any imapct on you receiving the spuosal benefits.
