Basis and Reasons for the Petition

• She argued that her enrollment in schools, from grade school through college, was under the name Estrella S. Alfon.
• The usage of the name in various facets of her life (e.g., suffrage records, academic diplomas) reflects a well-established identity that differs from her birth name.

Issue:

Legal Sufficiency of the Grounds for Name Change

• Whether the petitioner’s long-standing use of the name Estrella S. Alfon constitutes a proper and reasonable ground for changing her name in open court.
• The issue of whether the change should encompass both her first name and her surname, given that her birth records indicate her father’s surname (Duterte).

Interpretation of Civil Code Provisions

• Whether Article 364 of the Civil Code, which states that legitimate and legitimated children shall principally use the surname of the father, precludes the petitioner from legally adopting her mother’s surname.
• The legal interpretation of the term “principally” in this context – if it implies an exclusive use of the paternal surname or allows for the use of the maternal surname as well.

Applicability of Judicial Precedents

• Whether the precedent set in Haw Liong vs. Republic, which considers factors like the avoidance of confusion and well-established use of a name, applies in determinations of proper or reasonable cause for change of name.
