Pinnel’s Case (1602) 5 Co Rep 117a stands for the rule that payment of a lesser sum on the day a greater sum is due is not good consideration to discharge the whole debt — unless there is some fresh consideration (e.g. payment earlier, at a different place, by a different thing, or other added benefit).

Key area: Consideration (Contract Law) – Part payment of debt
Facts
Cole owed Pinnel £8 10s.
Pinnel agreed to accept £5 2s 6d, paid early, as full settlement of the entire debt.
Later, Pinnel sued Cole for the remaining balance.
Cole argued that Pinnel had already accepted the part payment as full satisfaction.
The Legal Issue
Is part payment of a debt, on the due date or earlier, good consideration for discharging the whole debt?
The Rule (The Pinnel’s Rule)
Acceptance of a part payment of a debt is not good consideration for a promise to discharge the whole debt — so the creditor may still claim the remainder. In short: part payment of a debt (without more) does not extinguish the balance.
If you owe $100 and pay $60, that does not legally settle the entire debt unless something extra is given.
Why?
Because the debtor is doing less than what they are already obligated to do.
The Exceptions
Later developments like Foakes v Beer (House of Lords) accepted/affirmed the rule that part payment is not good consideration for discharge of the balance — the rule in Pinnel’s Case was applied.
However, judicial decisions over the years have recognised a number of exceptions that operate to limit the rule’s rigidity.
A creditor’s promise to accept less may be binding where there is something more than mere part payment, for example:
- Fresh/extra consideration (e.g., giving something other than money).
- Payment earlier, or at a different place or in a different form, at the creditor’s request.
- A sealed deed effecting the release.
- Composition with creditors / insolvency arrangements.
- Promissory estoppel (equity): If the creditor promises to accept less and the debtor reasonably relies to their detriment, equity may prevent the creditor resiling (refer High Trees / Denning J on promissory estoppel). These developments have limited Pinnel’s rigidity in practice.
The Court’s Decision in Pinnel’s Case
Cole’s early part payment could be good consideration. But Cole did not plead this exception properly. So Pinnel won the case.
