Hello Guys
Please Help

I am British and lived in the Philippines for 2 years in 04/06 and during that time my eldest son came to visit and got a neighbour pregnant and came home before the birth.

OK for 2 years I have been trying to get my grandson a UK birth certificate and feel I am almost there, but need to know what steps I take now.

I am in receipt of the following documents from over a period of time which was a headache believe me

1 x Affidavit of paternity from Philippines embassy sworn and signed by my son and to use his surname on the birth certificate

1 x local Pangasinan birth certificate (In Fathers Surname)

2 x NSO Certificates from Manila

1 x Civil Registry Office (Manila) Certification of Paternity

1 x Authentication document (Dept of Foreign Affairs) Manila

1 x Affidavit of late registration

See, told you it was a headache. Can I register him with a UK birth cert in the UK with these documents or do I have to send his mother to a consulate ?

Passport I can obtain once he has his birth cert.
I value anyones help.
Thank you guys
