ADM.4:4.1 - Start from the receiving action

State what each relevant participant needs to decide or perform. A payer may need to establish whether an obligation is discharged; a recipient may need to allocate a receipt to an invoice. The administrative correspondence serves those actions.

Recover each source statement in its own terms. Ask what the participant means by “paid”: an instruction was issued, a transfer settled, or a particular obligation was discharged under an applicable rule. Retain the author, source, intended use and time when those facts affect interpretation. The exact authority of a source matters to the claim for which it is used.

Do not demand a universal vocabulary before an ordinary action can proceed. If a supplied statement is already clear and adequate, use it.
