Selling half a property to partner?

[Tim Barry]

Hey all, I purchased my first rental on my own and then teamed up with a partner (family member) and have bought several more 50/50. I was wondering what needs to be done to sell half the one I own to him? Can we just do something simple,fill out something and he's on the deed and he cuts me a check? Does a title company need to be involved like any regular closing we've done? Thanks in advance!
