There are 3 types of deeds, Quit claim, warranty and I forget the third. Quit claim essentially says IF I own something, it is now yours, it doesn't warranty that you actually own anything. It's just easy to do on your own though a Warranty deed isn't that difficult to do by yourself either. It's great for changes between family, friends and adding or deleting people from the ownership. It's been said but I don't know for certain, that you can't get title insurance if there is a quit claim deed in the lineage.
DVC uses quit claim deeds when they buy back under ROFR.
