That which is due unconditionally is due now.

Explanation

(English-origin maxim.) An unconditional debt is presently due and payable — the debtor cannot delay payment by claiming no time for performance was specified.

Where this applies

• A contractor finishes building a house and sends the final invoice with no payment due date specified — the full amount is due immediately because the obligation is unconditional.
• A borrower signs a promissory note with no maturity date, and the lender demands payment right away — since no condition was attached, the debt is presently due.
• An employee is owed a bonus with no conditions or timeline attached, and she demands it immediately because what is due unconditionally is due now.
