Have to agree with you Joe..If the guy had absolutely no money or interest in his kids he probably could be paid to sign anything.. In this case he will most likely fight to the death for them..(If only because of his Filipino pride)
If he is as contacted as Mark says then he can make just about anything happen..
Sounds like a very complicated arrangement and yet quite common here..
There are many women that get married to foreigners and leave their kids in the P.I.. to support them from foreign lands but in this case who could she leave them with even if she was prepared to do that?
Also Mark...Be careful if you fly back to see this girl and her kids again..This guy could be a real danger to your health if he were to find out or have prior knowledge of your arrival..
