Jobe,
Interesting topic, Quitclaim deeds. I'm hoping you've noticed what both definitions say, and is in agreement with what I originally said, that a quitclaim deed ONLY conveys interest in real property in which the grantor HAS title. As the 2nd definition also says it's a tool to clear up a title as well, but DOES NOT IMPLY the grantor actually has a claim or interest in said real property.
Just as an example, I owned a home a few years ago. I COULD grant you a Quitclaim deed on that property. You could even pay me, say, $1500, for it if you like. Does that mean that you now own that home? Not necessarily. In fact, in this case, absolutely not. When I sold that home 10 years ago, my interest was sold with it. In other words, after the sale, I have no legal interest in that property whatsoever -- especially after signing documents conveying ANY and ALL interest to the buyers -- , and any subsequent quitclaim deed I may sell you on that property would be worthless.
Now, let's just say that there WAS a part of that home -- a detached garage -- that somehow was on a separate title. This is just an educated guess on my part, but I don't think a Quitclaim deed granted to YOU would ever result in you successfully getting that garage from the new owners. Get the picture? Possession really IS 9/10th's of the law in that regard.
