The method for the coexistence of self written wills and written wills: if one of the wills is notarized and there is conflict between the two wills, the conflicting part shall be treated as a notarized will rather than a notarized will. If two wills have not been notarized and multiple wills are in conflict, the latter will will prevail over the earlier one. If there is no conflict between the two wills, they shall take effect respectively according to law.
