Filiation is the legal relationship between a child and their parents, and it can be legitimate or illegitimate. It is established by primary evidence: the record of birth appearing in the civil register, or a final judgment; or an admission of legitimate (or illegitimate) filiation in a public document or a private handwritten instrument signed by the parent. In the absence of these, filiation may be proved by secondary evidence: the open and continuous possession of the status of a legitimate (or illegitimate) child, or any other means allowed by the Rules of Court and special laws. Voluntary recognition of an illegitimate child is commonly made by signing the birth certificate or executing an affidavit of acknowledgment. Modern practice strongly recognizes DNA evidence as a reliable means of proving or disproving biological parentage. Establishing filiation matters because it determines the child's rights to use a surname, to support, and to inherit. There are also prescriptive periods and rules on who may bring the action to establish or impugn filiation.
