Every parent, but also the child have a right of access and visitation. This would be considered to be child custody law. The subject of this right of access and visit is the personal interaction between parent and child. Incidentally, this right belongs to parents as well as to other persons (such as siblings) if this is beneficial to the best interests of the child. The law assumes that in view of the development of the child, both parents should have lively contact with him. It makes sense that both parents agree together, as the visit contacts of the child to the parent are exercised, in which the child does not live permanently. If the right of access with his child is withheld from a parent, the family court can be called. In cases of dispute, courts usually give a visit to the parent who does not live with the child every 14 days. In cases where the parents are particularly divided and the judge is of the opinion that the child is involved negatively in the parents' conflicts, the judicially pronounced treatment can even be less common, in extreme cases, the family court even pronounces prohibition of access to a parent. On the other hand, if there are particularly close relationships with the child, courts also give more interaction, especially if the transfer of the children from one parent to the other parent works in a harmonious way. If the judge is in the dark as to what the right of access to the welfare of the child looks like, or who should get the right of custody or residence, the court will seek an expert opinion, for example, a child psychologist. The interests of the child can be represented by a mediator ("advocate of the child") who is specifically employed by the family court in disputed cases.
