A quitclaim deed releases a person’s (the grantor’s) interest in a property without establishing the interest or even ownership. While a quitclaim deed does not establish ownership, it does prevent the grantor from later seeking to establish an interest in the property.
In colloquial English, a quitclaim deed states "I relinquish any interest or claim upon the property, whether or not I have any such interest or claim." For most purposes, a title company will not clear a title solely based on quitclaim deeds. When selling real estate, the seller is often required to sign a quitclaim deed.
