After making the last post, looking at the advertisement menu above, I noticed an ad for quitclaim deeds.
Under the california section it defined quitclaim deed thus;
Quitclaim deed: A real property deed which transfers (conveys) only that interest in the property in which the grantor (seller) has title, quitclaims are often made to family members, divorcing spouses, or in other tranactions between people well known to each other. Quitclaim deeds are also used to clear up questions of full title when a person has a possible but unknown claim or interest in the property.
