A more thorough explanation:

Term: In render
Definition: In render means that something is required to be given or paid. It is a legal term that refers to property that must be surrendered or given up. Examples: - The tenant was in render of the apartment keys to the landlord. - The company was in render of the payment for the services provided. These examples illustrate the definition of in render because in both cases, something was required to be given or paid. The tenant had to surrender the apartment keys to the landlord, and the company had to pay for the services provided. In both situations, the term in render is used to indicate that there is an obligation to give or pay something.
