If you are pregnant and the father of your child refuses to assist you in payment of the expenses while preganant, you should consult with a family law attorney immediately.If you cannot afford one, most counties in this country have a division of their district attorney's office that deal with "aid to families with dependent children" that possibly could assist in child support obligations down the road of the father once the child is born and your boyfriend is decided to be the child's father.You might consider filing a petition in your county's superior court against your boyfriend for assistance in the unborn child's expenses while you are pregnat assuming he admits that the unborn child is his.Good luck.
