If the biological parents of a child are going through a divorce, they have the right to seek child custody, or parenting time, also called child visitation. The parents of a child can seek custody or visitation, regardless of the fact whether they were ever married or not when the child was born. When courts take a decision, that decision is taken based upon the best interest of a child. Usually, courts are required to take a decision in cases related to disputed child visitation, or custody cases where the parents were never married.
Paternity means the condition of being a father. Establishing paternity means to establish a legal father for a child. When the parents are not married it is important that paternity be legally established.
