Ad hoc was first used in Britain as early as 1545 in Latin texts rather than English. The English of that era was strongly influenced by Latin as used by the church and by educators.

English borrowed the Latin phrase ‘ad hocin’ the mid-1500s when the expression was quickly being adopted into legal and judicial writings.

Ad hoc spreads as a term in such contexts in the 1800s. A Louisiana Code of Practice for civil law from 1839, for example, lists the various situations where a person, such as a minor, may be assigned what is called a curator ad hoc, a “caretaker for this purpose.” An 1869 judicial report from the state of New York, as another instance, describes forming ad hoc committees by the courts to investigate specific matters.
