IPA: //nɒnˈkʌstəˌdiəl//
KK: /nɑnˈkʌstəˌdiəl/
Relating to a situation where a parent does not have full custody of their child, often sharing custody or having limited time with the child.
The noncustodial parent is allowed to visit the children on weekends.
Noncustodial → It is formed from "non-" (meaning not) and "custodialis" (from Latin "custodia", meaning custody or guardianship). The word refers to a situation or arrangement that does not involve custody or guardianship.
Think of 'not' ('non-') being involved in 'guardianship' ('custodia') — that's why noncustodial means not having custody.
