If a rural homestead of a single adult person, not otherwise entitled to a homestead, is part of one or more parcels containing a total of more than 100 acres, the person may voluntarily designate not more than 100 acres of the property as the homestead.
(b) If an urban homestead of a family, or an urban homestead of a single adult person not otherwise entitled to a homestead, is part of one or more contiguous lots containing a total of more than 10 acres, the head of the family and, if married, that person’s spouse or the single adult person, as applicable, may voluntarily designate not more than 10 acres of the property as the homestead.

(c) Except as provided by Subsection (e) or Subchapter B, to designate property as a homestead, a person or persons, as applicable, must make the designation in an instrument that is signed and acknowledged or proved in the manner required for the recording of other instruments. The person or persons must file the designation with the county clerk of the county in which all or part of the property is located. The clerk shall record the designation in the county deed records. The designation must contain:
