Contacts with children may be regulated in the divorce decree, e.g.:
in detail in a schedule of meetings / phone calls (with specific dates and hours of meetings) or
very wide / unlimited – each time individually agreed between the parents.
If you prefer contact with the child to be regulated in detail by the court, you may request various forms of keeping in touch with children, in particular:
maintaining correspondence,
using other means of distance communication, including electronic means of communication,
being with the child – visits, meetings, taking the child away from his / her place of permanent residence and direct communication (the court may decide that the parent may take the child abroad as part of the contact).
