Quick answer
There is no single countdown for every old debt. You may need to track the Prescription Act period, a response date in a demand or credit notice, and a court deadline at the same time. These clocks do different work. A letter's requested reply date does not decide when prescription began, and a possible prescription defence does not suspend a summons.
How to use this guide
The safest approach is to build a calendar from the contract, debt category and service records, then verify each legal deadline under its own source. If court process has arrived, obtain advice immediately instead of waiting for the prescription calculation to be completed.
First clock: the applicable prescription period
Section 11 of the Prescription Act lists several periods. It includes 30 years for specified debts such as judgment debts and debts secured by mortgage bonds, 15 years for certain State debts, six years for debts arising from listed instruments and a residual three-year period for other debts. The category must be established before a date is calculated.
Do not describe every consumer account, invoice, loan or suretyship as a three-year debt. Confirm the instrument, parties and any other legislation that may govern the claim.
Second clock: when the debt became due
Under section 12, prescription generally starts when the debt is due, subject to statutory qualifications. Identify the contractual maturity date, instalments, performance date, default, cancellation and any acceleration clause. Where demand is mentioned, determine whether it is genuinely required to complete the claim or merely sets a period for payment after the right to claim already exists.
The Constitutional Court in Trinity Asset Management v Grindstone Investments held that wording making payment occur after demand did not necessarily permit the creditor to choose indefinitely when prescription would begin. The decision requires a fact-specific reading; it does not create a shortcut that demand is always irrelevant.
Third clock: knowledge and delayed completion
Section 12 also deals with the creditor's knowledge of the debtor and the facts from which the debt arises. That enquiry may affect the starting point, but it is based on evidence and the statutory standard rather than the date on which a creditor says it opened a file.
Section 13 lists circumstances that may delay completion of prescription. If a relevant impediment existed near the end of the ordinary period, the section can produce a different completion date. Record the start and end of the possible impediment and obtain advice on the specific paragraph rather than adding a generic extension.
Fourth clock: acknowledgement and service events
An express or tacit acknowledgement of liability can interrupt running prescription under section 14, after which a fresh period may begin as the section provides. Put payments, signed acknowledgements, promises, instalment requests and settlement communications on the calendar. The issue is their objective legal effect in context, not the label used by either party.
Service of process claiming payment can interrupt prescription under section 15. Record the service date and the result of the proceedings. The interruption can lapse if the claim is not successfully prosecuted to final judgment, and different consequences follow if judgment is abandoned or set aside. The date a summons was issued is therefore not a sufficient substitute for the service and case history.
A summons creates its own urgent timetable
Magistrates' Court and High Court procedures are governed by different rules and forms. Ordinary summons procedure often gives a short period to deliver a notice of intention to defend, followed by further pleading deadlines. Read the exact served document, court, service date and current rule instead of relying on a generic internet statement that everyone has the same number of “business days”.
Negotiating, requesting statements, complaining to a regulator or asking the plaintiff for time does not itself deliver a notice to defend. A late notice may sometimes be delivered before default judgment under the relevant rule, but relying on that possibility can expose the debtor to default and costs.
If judgment already exists, rescission and enforcement issues have separate rules and factual requirements. A prescription argument about the original debt should not be treated as an automatic way to remove an existing order.
National Credit Act dates are not universal debt dates
Where the claim is under a credit agreement to which the National Credit Act applies, sections 129 and 130 create a pre-enforcement framework. The agreement type, consumer, default history, delivery of the statutory notice and procedural status all matter. Those provisions should not be imported into an ordinary trade invoice or other excluded transaction.
Section 126B also addresses prescribed debt under qualifying credit agreements. It does not remove the need to classify the agreement, preserve the response and deal with court process correctly.
Build one calendar with separate columns
Use columns for the event, source document, legal issue, date, proof and action required. Include:
- each contractual due date and alleged default;
- relevant knowledge evidence and any section 13 impediment;
- every possible acknowledgement or part payment;
- issue and service of court process and later case events;
- dates in demands, credit notices and complaint responses; and
- the precise filing or appearance deadline on any served court document.
Mark uncertain dates instead of inventing precision. Ask the lawyer which deadline controls the immediate next step and what can be investigated in parallel.
FAQs
Do all ordinary debts prescribe three years after the last payment?
No. The debt must first be classified, and the start, delay and interruption rules must be applied to the actual agreement and events.
Does asking the creditor for more time pause a summons?
Not by itself. Use the deadline on the served process and current court rule unless a valid extension or court step changes it.
Is the summons issue date enough to interrupt prescription?
Section 15 focuses on service of process, and the later result of the proceedings also matters. Obtain the return of service and case history.
Should I wait for a full prescription opinion before defending?
No if court time is running. A lawyer can address the immediate procedural filing while the deeper chronology is investigated in parallel.
