Kabayan, its better if you consult a lawyer regarding your queries.

This forum is not the proper venue for you to asks such questions. It involves other people as well one baby.

Its correct that you fight for your baby's right but it should be on a proper venue and not on a public forum.

Try to talk to him first and if there's no positive response then you should seek for a legal advise or legal move but whatever would be the outcome you should be prepared for the consequences of your actions.

Goodluck
