The amount of child support is 15 to 25 percent of the parent's salary that is required to pay maintenance. Exactly how much is decided by the court, taking into account other considerations. Aspects: First, it is very important how much a child has so-called financial needs, as a sick child may have much higher financial needs than a healthy one. The court will also take into account if the child has his or her own income. It also matters how much income the parents have and what their financial situation is. The court must take into account how many foster children have a child in a household with him or her. The amount of child support is also affected by the fact that the child or the parent raising him or her receives this kind of social benefit. These factors affect how much a fixed amount of child support is awarded by the court. If the person liable for child support has no claim or just does not confess, the child support may be charged against other property or movable property in civil proceedings. If there is no declared claim and no assets, not much can be done. :(
