Is it necessary for me to deed property over if I am not in the will? My father died and my mother said he did not have a will.

The correct term is "quitclaim," not "quick claim." The purpose of having you execute such a deed is to relinquish whatever rights you may have in the property. If there was no named joint owner of the property with your father, upon his death ownership of the property passes as provided under his will, or, if there is no will, to his heirs at law. You are one of his heirs. Apparently your mother's attorney has decided that you have acquired, or may have, some interest in the property under the laws of intestacy and she wishes you to relinquish your interest to her.
