Anybody from Mississippi or know about law?

I have a friend who lives in Mississippi and made a poor choice to move down with his girlfriend whom he was already having a ton a different issues with. As his bff, I suggested that He don't do it, know the problems are worse. He finally figured out a way to get her name of the lease, but she will not voluntarily go. He is a sweet guy so he isn't gonna throw her things out on the sidewalk. What can he legally do. He said there was some law stuff there that makes it a bit diffucult to get her out.
