Spouses Crispin Aquino v. Aquino

Summary

This property dispute involved family members where spouses Aquino owned property occupied by spouses Aguilar (Teresa's sister and brother-in-law) since 1981. Respondents demolished existing house and built three-storey building, contributing P1 million and supervision services, occupying half of third floor rent-free for 20 years. When petitioners demanded vacation in 2003, respondents claimed co-ownership and builder in good faith status. All courts rejected these claims, finding respondents were builders in bad faith due to petitioners' 1983 letter prohibiting construction. Supreme Court ruled Article 1678 inapplicable to occupants by mere tolerance, only to lessees, but allowed reimbursement for necessary preservation expenses under Article 452 without retention rights. Case demonstrates Civil Code provisions on accession, good/bad faith building, and property possession rights.
