Tan v. Local Civil Registrar of Makati City
REITERATIONFacts
The Antecedents: Petitioner Kimric Casayuran Tan, a former natural-born Filipino now a British citizen, sought to change his registered surname from "Tan" to "Casayuran." He claimed that although his birth certificate lists his surname as Tan and his father as Carlos Tan, he has never used the surname Tan and never knew his father, who abandoned him and his mother in infancy. Instead, he has consistently used the name "Kimric Florendo Casayuran," incorporating his mother's maiden name and surname. This name has been used in his schooling, official documents, marriage certificate, and his daughter's birth certificate. Procedural History: The petitioner filed a Petition for Change of Name before the Regional Trial Court (RTC) of Las Piñas City. The RTC, after publication and hearing, denied the petition, finding that Kimric failed to prove he was widely known by the name "Kimric Casayuran" and that the discrepancies in his documents cast doubt on his credibility. The Court of Appeals (CA) affirmed the RTC's decision, holding that the petitioner's use of his mother's maiden name was not a valid reason for changing his surname and that it created confusion regarding his parentage. The CA also found it suspicious that Kimric claimed to have only recently discovered the discrepancy in his surname. The Petition: Kimric Casayuran Tan filed a Petition for Review on Certiorari under Rule 45 of the Rules of Court, seeking to reverse the CA's decision. He argued that he has been using the name "Kimric Florendo Casayuran" since childhood, and all his official and personal documents, including his marriage certificate and his daughter's birth certificate, reflect this name. He contended that using "Tan" would cause confusion and embarrassment, as it is not the name by which he is known in his community. The Office of the Solicitor General (OSG) raised a procedural issue, arguing that the RTC lacked jurisdiction due to a defective publication of the notice of hearing. The Supreme Court, however, found that the OSG, by actively participating in the proceedings, was estopped from questioning the RTC's jurisdiction. The Court then ruled on the merits, finding that Kimric had sufficiently established a proper and reasonable ground for the change of name, primarily to avoid confusion and embarrassment, and granted the petition.
Issue(s)
Whether the Supreme Court has jurisdiction over the petition despite alleged defects in the publication of the notice of hearing. Whether Kimric is entitled to a change of name from "Tan" to "Casayuran."
Ruling
The Supreme Court granted the petition, reversing and setting aside the decisions of the Court of Appeals and the Regional Trial Court. The Civil Registrar of Makati City was directed to change petitioner's name from "KIMRIC CASAYURAN TAN" to "KIMRIC FLORENDO CASAYURAN."
Ratio Decidendi
On the issue of jurisdiction: The Supreme Court ruled that the OSG is estopped from questioning the RTC's jurisdiction. The OSG actively participated in the proceedings before the RTC, including cross-examining witnesses, and had ample opportunity to raise the issue of jurisdiction earlier. To allow the OSG to question jurisdiction at this late stage would make a mockery of the judicial process and render the proceedings before the RTC inutile. The Court reiterated that a proceeding for change of name is an in rem proceeding requiring strict compliance with jurisdictional requirements, particularly publication, but found that the State's interests were adequately protected by the public prosecutor's participation. The publication of the Order, which included both the name used and the name sought, satisfied the purpose of informing the public. On the entitlement to a change of name: The Supreme Court found that Kimric sufficiently established a proper and reasonable ground for the change of name, primarily to avoid confusion. The records showed that Kimric had been using the name "Kimric Florendo Casayuran" since at least 1988, when he was ten years old, and continued to use it for over 33 years. Numerous official documents, including Philippine and British passports, school records, driver's license, and marriage certificate, bore this name. His wife and daughter also used the surname Casayuran. The Court noted that compelling him to use "Tan" would inevitably lead to confusion and require alteration of all his official documents, as well as those of his family. The discrepancy in the place of birth between his birth certificate and other documents was attributed to his mother's inadvertence when he was a child, and did not detract from his consistent use of the name "Casayuran" for most of his life. The Court emphasized that a change of name does not affect one's parentage or legitimacy, as the birth certificate remains the primary record for such matters.
Main Doctrine
A petition for change of name may be granted upon a showing of a proper or reasonable cause or compelling reason therefor, such as to avoid confusion, provided that the State's interests are protected and the petition is not filed for fraudulent purposes. Estoppel may bar the State from questioning jurisdiction if it actively participated in the proceedings.
