This is a child who would be considered a qualifying child if an application for child support could be made for her/him. It includes a child who does not live with the non-resident parent and a child whose care is shared between the non-resident parent and someone else. A child who is not a qualifying child and who is habitually resident in the UK can also count as a relevant non-resident child if the non-resident parent is paying maintenance for her/him under another informal maintenance arrangement, i.e. a family-based arrangement.
