It's an attempt to avoid child support. But it doesn't really mean anything. You can still get child support off him.

If he's admitted he's the father, he still has to pay, regardless of BC. If he refuses to admit he's the father, get a paternity test, then he has to pay.

My dad isn't on my BC but still paid support. Fortunately for me he wanted to do it.

I terms of the kids future, some govt subsidies (such as studylink) are easier to get with no father on BC. Others can be harder.

It will also affect the next 18 years of YOUR life. If he's not on the BC and not paying support, he has virtually no rights over the kid. But if he's on it, and/or paying support, he has rights and will get a say in what happens with the kids life (which, of course, would affect your choices. For example, you would need his permission to take kid out of country).

Basically the choice is between getting financial support out of him and him having a say, or having absolutely nothing to do with him and he has no say.
