Estate of Arnulfo Sison v. Marie Arnulfa Castillo Sison

Summary

This case involves a child support dispute that originated in 1995 when Marie Arnulfa Castillo Sison sought support from her putative father Arnulfo Sison Sr. A compromise agreement was executed in 1996 establishing monthly support of P2,250, later increased to P6,000 in 2002. When Sison failed to comply, execution proceedings led to the levy and auction sale of his property in Oriental Mindoro, with Marie as the winning bidder. After Sison's death, his estate challenged the validity of the compromise agreement under Article 2035 of the Civil Code, arguing it improperly dealt with future support and filiation. The Supreme Court rejected these arguments, ruling the agreement pertained to present support obligations and was validly executed. The Court emphasized that compromise agreements have res judicata effect and cannot be disturbed absent vices of consent. The case demonstrates the enforceability of support obligations and the finality of compromise agreements in family law disputes.
