Qualifying Child(ren)
A qualifying child is a child where one or more of his parents are non-resident parents.
Relevant Other Child(ren)
A Relevant Other Child or Relevant Child, is a child other than a qualifying child for whom the NRP or her/his partner receives child benefit.
This can include a child who does not live the parent all the time, i.e. because there is a shared care arrangement for her/him.
Relevant Non-Resident Child(ren)
A Relevant Non-Resident Child or Children is a child of the non-resident parent for whom an application for child support cannot be made because the non-resident parent is liable to pay maintenance for her/him under a maintenance order, an order of a non-British court or under the legislation of a country outside the UK.
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.
