The homestead of a family shall not be conveyed or encumbered by a spouse without consent of the other spouse. The consent shall be evidenced by each spouse joining in the conveyance by signing their names thereto, and also by acknowledgment thereof. Consent of a nonowner spouse shall not be required where the homestead property is conveyed or encumbered by an owner spouse who holds title to the property as sole and separate property.
