Yes. Child support and child visitation are not related. If your husband is not paying you child support, you need to obtain a court order requiring him to do so. If you have a court order and he is not honoring it, there are ways to make him pay. In California, child custody is determined by what is in the best interest of the children. Custody is based upon a number of factors, including which parent is more likely to allow the other parent to have frequent and continuing contact with the children. If you do not allow your husband to see the children because he is not paying you child support, you risk losing custody.
