Dear Kitchen,
A true quitclaim does not even convey property, because a true quitclaim deed (QCD) does not have words of conveyance. Simply, Grantor quitclaims unto Grantee, etc...
What that means is that Grantor "Quits" any claim to the property that Grantor possesses at that instant in time. The QCD has no effect on any after-acquired title.
Most landmen and title examiners like a QCD about as much as a Sheriff's Sale.
Best,
Buddy Cotten
