Can DNA evidence be used to prove paternity in the Philippines?

Answer

Yes. DNA testing is an accepted — and in many cases conclusive — means of proving or disproving paternity and filiation in the Philippines. The Supreme Court has recognized its use, and the Rule on DNA Evidence (A.M. No. 06-11-5-SC) governs how DNA testing is ordered, taken, and evaluated by the courts.

A high probability of paternity from a valid DNA test carries strong evidentiary weight, while a result excluding the putative father is conclusive that he is not the biological parent. An action to claim illegitimate filiation that rests on open possession of status or other proof must generally be brought during the lifetime of the alleged parent; where it rests on the record of birth or a signed admission, the time limit is different.
