However, there are several situations in which dads are entitled to child support. Kid support is usually paid to the parent who has primary custody of the child. In certain states, unmarried moms enjoy automatic custody rights over their children, but the father must first demonstrate paternity before getting rights to his or her kid. If the mother and father are married, they can agree that the father will be responsible for paying child support. In addition to being responsible for supporting his or her kids, fathers also have the right to visit their children. The amount of time that a dad can expect to spend with his kids depends on the state that it is in but most allow at least weekly visits. Sometimes visitation can be extended further if the judge believes it is in the best interest of the child. States vary when it comes to determining how much money is considered "child support". Some use a formula called "child care costs minus two hundred dollars a month" while others rely on the federal government's guidelines. Most states also offer an option where parents can submit evidence that proves what kind of support would be reasonable if the court isn't sure how to calculate it. For example, one parent might have a high-paying job while another doesn't. By submitting information about their income and expenses, the parents can have the court determine what kind of support would be reasonable. All states require child support to be set in accordance with the needs of the child.
