Etymology
The word is a modern English compound formed by adding the common negative prefix "non-" to the existing adjective "custodial." The core concept stems from Latin custodia, meaning "a guarding, protection, custody," which itself derives from custos, meaning "guardian, keeper, watcher." The prefix "non-," also from Latin, straightforwardly negates the base term. Thus, the literal construction "not relating to custody" evolved to its primary modern legal usage, specifying a parent who does not have primary physical care of a child, and a secondary financial usage for services that do not hold client assets.
