because he is financially responsible for the child! just because he decides he wants nothing to do with the child doesn't negate his responsibility! he is not a sperm donor, he is the father. whether you are still together or not, you created a child together and he is responsible for paying for contributing to it's upbringing!

the government helps you out with support while you raise your child, provided the parents are supporting the child as well. it is not up to the tax payer or the government to support a child simply because the parent decides they dont want to. it is completely reasonable for minimum payment to be made if the caring parent won't make an effort to have the non-caring parent support their child. there are obviously exceptions to the rule (where DV is involved, or genuine cases of paternity unknown) - but simply not chasing it because the other parent is being a deadbeat is a cop out.

the CSA will do all the chasing, so there is no need for you or your child to have any contact - but the other parent SHOULD be held responsible.
