can my boyfriend's ex keep his last name?

[Kats1013]

All parties involved live in Tennessee. The man I am dating has been divorced for a little over a year. In the divorce agreement, his ex agreed to take back her maiden name. We recently found out that she is still using his name. Can she do this even though they agreed otherwise? If not, what can he do to stop her?

Thanks so much!!!

My response:

There is no law that can "force" her to revert to a previous name. If she wants to use his last name, because she legally used that name during their marriage, she has every right to do so until she decides to change it.
