Pfa against daughters father..custody rights?

He is either stupid or bluffing. Any person with common sense would know that if he seeks cusotdy you will go for child support. And, if you go for child support he will seek custody. I think you have little to worry about now. However, he is playing games with you so that you do not seek child support. You should consult a lawyer or legal aid where you live to learn about how to get child support and what his chances of getting some custody/visition might be.
