Article 263

The action to impugn the legitimacy of the child shall be brought within one year from the recording of the birth in the Civil Register, if the husband should be in the same place, or in a proper case, any of his heirs.

If he or his heirs are absent, the period shall be eighteen months if they should reside in the Philippines; and two years if abroad. If the birth of the child has been concealed, the term shall be counted from the discovery of the fraud. (113a)
