In all cases where a deceased person has left a widow or husband, as the case may be, or other heirs at law, then such widow or husband or other heirs at law, or both, who may be entitled by law to inherit from the deceased person, shall be entitled to have the homestead exempt, whether selected, designated or declared for by said decedent in his lifetime or not, and such person or persons so entitled to inherit by law may select, designate or declare for such homestead on or any of the real property of which said decedent died seized and possessed, and have the same set apart to them, or either of them, as the homestead of the decedent.
