I can share some general knowledge about quitclaim deeds with you. Whether executing one will lead to the results you are looking for, I don't know.

A quitclaim deed is one where an individual conveys all interest they have in a property to the grantee named on the deed. They differ from you typical deed which is known as a warranty deed because there the grantor "warrants" that they have clear title to the proprety being granted. If it turns out that they didn't have clear title to the property that they appeared to convey to the grantee then they could be on the hook for some legal and financial recourse. With a quit claim deed they are merely giving up whatever claim they in the property (if any) to the grantee named in the deed. I could quitclaim the Brooklyn Bridge to you, but I doubt that you would then own it. But if the grantor in the deed did have valid title to the property then, once conveyed, a quit claim deed is just as strong and binding as a warranty deed.

Hope this helped.
