In the Philippine legal system, the rights of illegitimate children—those born out of wedlock—are protected under the Family Code of the Philippines and supplemented by landmark Supreme Court rulings regarding scientific evidence. Establishing filiation is the primary hurdle for securing support and successional rights.
I. The Legal Status of Illegitimate Children
Under Article 175 of the Family Code, illegitimate children are established by the same evidence as legitimate children. They are entitled to use the surname of their father if their filiation is expressly recognized through:
- The record of birth appearing in the civil register.
- An admission of paternity in a public document or a private handwritten instrument signed by the parent.
In the absence of these documents, filiation must be proved through court action, where DNA testing has become the gold standard.
II. Compulsory DNA Testing: The Rule on DNA Evidence
The Supreme Court, in the case of Herrera v. Alba, and later through the Rule on DNA Evidence (A.M. No. 06-11-5-SC), formalized the use of genetic testing in paternity suits.
1. Application for DNA Testing Order
A party (usually the mother or the child) may file a petition for compulsory DNA testing. The court does not grant this automatically; the petitioner must show a prima facie case or a reasonable possibility that the respondent is the biological father.
2. The Testing Process
- Sample Collection: Biological samples (usually buccal swabs or blood) are taken from the child, the mother, and the alleged father.
- Chain of Custody: The court ensures a strict chain of custody to prevent tampering or contamination.
- Standard of Probability:
- If the value of the Paternity Index is 99.9% or higher, a rebuttable presumption of paternity arises.
- If the probability is lower, it may still be considered corroborative evidence but is not conclusive.
3. Refusal to Undergo Testing
While the court cannot physically force a person to undergo a medical procedure against their will, a respondent’s "unjustifiable refusal" to submit to a DNA test can be used as a "disfavorable inference" against them under the rules of evidence.
III. The Claim for Child Support
Once filiation is established—either through voluntary recognition or a court-ordered DNA result—the right to support becomes demandable.
1. Nature of Support
Under Article 194 of the Family Code, support (sustento) comprises everything indispensable for:
- Sustenance and dwelling.
- Clothing and medical attendance.
- Education (including transportation and school supplies).
2. Amount of Support
There is no fixed "table" for child support in the Philippines. According to Article 201, the amount is "proportionate to the resources or means of the giver and to the necessities of the recipient." It is subject to the Principle of Variability: the amount can be increased or decreased by the court depending on the changing needs of the child or the financial capacity of the father.
IV. Procedural Steps for Filing
To legally compel a father to pay support via DNA testing, the following steps are generally followed:
- Filing of Petition: A "Petition for Compulsory Recognition and Support" is filed in the Regional Trial Court (Family Court) where the child resides.
- Motion for DNA Testing: During the trial, the petitioner moves for a DNA order.
- Judgment of Paternity: If the DNA results are positive, the court issues a decision declaring the respondent as the biological father.
- Order of Support: The court concurrently orders the father to provide monthly financial support. The court may also order Support Pendente Lite (temporary support) while the case is ongoing if the evidence of filiation is sufficiently strong.
V. Enforcement and Sanctions
Failure to comply with a court order for support can lead to:
- Civil Contempt: Fines or imprisonment until the order is obeyed.
- Criminal Liability: Under Republic Act No. 9262 (Anti-Violence Against Women and Their Children Act), the "willful deprivation of financial support" is considered a form of economic abuse, punishable by imprisonment and fines.
- Hold Departure Order: To prevent the payor from leaving the country to evade obligations.
