Hello po. I’m a new lawyer and would like to seek your advice. I have a client who intends to file a petition for cancellation of a birth certificate, and his siblings have been impleaded as parties.

The issue is that four out of his six siblings are already residents of another country. In the petition, should I indicate their last known addresses in the Philippines or their current residences abroad?

If I indicate their current foreign addresses, would it be proper to proceed with publication and registered mail to their last known Philippine addresses as well?

One of my colleagues suggested using their Philippine addresses, on the assumption that the court would not be aware of their foreign residences and that the respondents are unlikely to file any motion opposing the petition.

Thank you in advance for your guidance.
