In early modern usage, the term requisition (from Latin requirere, “seek,” “explore,” “demand”) appears in two main contexts.
1) In early modern legal language, requisition means quite generally to explore or investigate something; more specifically, it can also mean a house-to-house search or the requisition of a notary. In the 19th century, it was understood primarily as the request of an agency for legal assistance in a special document (requisitorial document).
