I have to say....I agree primarily with Broken .... men do have to just deal with the decision a woman makes when she falls pregnant. Yes, yes sex leads to babies, both parties know that, but it is then solely in the woman's hands what she does from there.
If you are bringing a little person into the world already knowing the father doesn't want anything to do with them (so sorry to hear that, I am in that same boat now with my 5yr old, ex partner has cut all contact) then you need to be prepared and able to deal with this 100% on your own. I don't believe you should have to at all, and it's not the fluffy pc thing to say, but the stark reality is, if he doesn't want to contribute in any way, you need to make sure you have the potential to provide everything your child needs. It's your duty as a mother. It's his duty as a father too, but again, without sugar coating, it's your decision to continue with the pregnancy even though he made his feelings very clear about what his involvement would be if you did.
I don't just mean the money either, he's already said he knows he has to pay something, but he'll probably do that begrudgingly, I mean you (until you meet someone else) will be doing all of the parenting.
I'm not trying to be a neg head, sincere congratulations on your pregnancy. I'm just speaking as someone no longer with DS' biological father, and I asked myself do I want to spend my life pestering for contact, chasing CSA/maintenance payments, or do I accept I am more than capable of providing for my own child, so whilst it's wrong that I have to be mum/dad/breadwinner all rolled into one, the reality is I am. And you need to be prepared to be able to be all those things too.
In answer to your questions, if not on the birth cert, yes you can still claim maintenance, and yes, he can apply to the courts for a contact order, and unless you can show a good reason why he must not see the child (but he's not been in his/her life for x months/years makes no difference) then you have to "make the child available" for him.
