A child cannot change their name without the consent of both parents until they are 18 (or from memory 16 in one state but I forget which).

But they can assume your surname without needing permission. You just start using it as their preferred name. You just have to remember that on official forms you have to use the correct one and for a littler person it can be very confusing as to which name they are supposed to use.

I don't for one moment think that you are being a cow and I know there are a million reasons for not wanting him in your life but you have to think of your daughter for a moment. He is still her father and she has the right to know him and I don't think that it should be you taking that away. If he wants to be a dead beat dad and not care about her in any way then that is something that they are going to have to sort out when she is older but I am not sure that you should be the one pushing him out of her life - it could lead to a lot of resentment later on.

Do you have sort of parenting agreement? If not then I think that this is something that you should get sorted out because he might just surprise you and want more contact. If you get it sorted out when he doesn't care then you get more of what you want.

In relation to CS - is CSA chasing him for it? I would ring them and tell them that you aren't getting it and you really need it.

Also, a lot of people get worried about the whole not leaving the country thing. Were you planning on moving overseas? If you are then you just have to reach an agreement with him in relation to it. A lot of people get upset about it and feel that their rights are being inhibited but to use an analogy if I were to tell you that you couldn't go to the moon you might get upset that I was taking away an option for you but were you really ever wanting to go to the moon? I guess not, so why are you upset about me telling you you cant? The provision is in place to protect parents and children from what can be genuinely dangerous situations but the courts tend to be very sensible about its use in normal day to day affairs.
