Quitclaim Deed
A deed that transfers whatever interest the grantor happens to own — with no warranty of title — common in title curative work and family transfers.
A quitclaim deed conveys whatever interest, if any, the grantor actually owns, and makes no promise that the grantor owns anything at all. There is no warranty of title and no obligation to defend the grantee. If the grantor owns nothing, the grantee receives nothing — but with no recourse.
Despite that thinness, quitclaim deeds are workhorses of title curative. They are used to clear a possible cloud (an old reservation, a misdescribed tract, a stray heir's potential interest) and to move minerals among family members or into a mineral trust where everyone trusts the title already.
For an arm's-length purchase, insist on a warranty deed instead — a quitclaim shifts all title risk to you. Heirs cleaning up an estate often combine quitclaims with an affidavit of heirship. This is general information, not legal advice.
