Statute of Limitations for Written Contract in Singapore

Overview

Run this scenario in DocketMath using the Statute Of Limitations calculator.

In Singapore, the time limit to sue on a written contract is generally 6 years under the Limitation Act (Cap. 163).

In practical terms, that means most claimants must file their court action within 6 years from the date the cause of action accrues. For written contract disputes, the “accrual” date is often linked to the breach—for example, when a payment becomes due and remains unpaid, or when a contractual deliverable is due and is not delivered in accordance with the agreement. The exact accrual point can depend on the contract’s wording and the nature of the obligation (single due date vs. instalments, conditions precedent, late performance, etc.).

This limitation framework is designed to balance:

• giving time to investigate and prepare a claim, and
• promoting legal certainty by preventing very old disputes from being litigated indefinitely.

Limitation period

For contract claims founded on a written contract, the baseline limitation period is 6 years from when the cause of action accrues.

To estimate your deadline, start by building a simple timeline:

1. Identify the event that constitutes the breach.
2. Identify the date the breach gave rise to a right to sue (the accrual date).
3. Apply 6 years (then check whether any exceptions modify the result).

Common fact patterns and how they can affect accrual

1) Payment due but unpaid (typical breach)

If the contract says payment is due on 1 March 2024, and you sue for the unpaid amount, the cause of action often accrues when payment becomes due and remains unpaid. The general deadline is then 6 years from that accrual date.

2) Deliverables due on a specific date

If goods or services were due on 15 July 2023, and they were not delivered (or were delivered late in a way that constitutes breach), the accrual date can track the scheduled performance date—subject to the contract’s terms and what counts as defective or late performance.

3) Ongoing obligations (series of breaches)

Where the contract involves repeated duties (e.g., monthly instalments), each missed payment can create its own cause of action. In many cases, that leads to a rolling accrual—so the deadline may differ for each instalment as it falls due and is not paid.

How to estimate your deadline quickly (worksheet-style)

What changes the timeline

Even with a baseline of 6 years, outcomes can change due to:

• when the cause of action actually accrues (especially for instalments and continuing breaches),
• certain events that can affect limitation analysis (e.g., acknowledgments in the right circumstances),
• statutory exceptions that can suspend, extend, or modify the standard period.

Key exceptions

Several exceptions and modifying rules may mean the “6 years” result is not a perfect fit.

1) Accrual: when the law says you could sue

Limitation is anchored to when the cause of action accrues—not just when the contract was signed or when problems were first noticed. For many written contract claims, accrual aligns with:

• the breach date, or
• the date performance became due and was refused/failed.

2) Acknowledgment or part-payment (time may be affected)

Certain limitation rules can treat particular conduct by the defendant as relevant. For example, an acknowledgment of the debt/claim or part-payment may affect limitation—but only if the statutory conditions are met.

3) Fraud or concealment (where relevant)

Singapore’s limitation framework includes mechanisms that can account for situations involving concealment or fraud, particularly where such issues affect when the claimant could reasonably discover the basis of the claim. Complexity alone usually does not automatically extend time—the applicable statutory conditions must be satisfied.

4) Disability or other special circumstances (less common)

Where the claimant is under a relevant legal disability (for example, incapacity as defined by statute), different rules can apply to when time starts or how it runs. These are highly fact-specific.

5) Mixed or alternative causes of action can create multiple deadlines

Even if a dispute involves a written contract, the claim might be pleaded through different legal bases (e.g., misrepresentation, restitution, tort, or statutory claims). Different causes of action can carry different limitation rules, so it’s important to identify what you are actually suing on.

Practical takeaway: treat the “6-year written contract” baseline as your starting point, then confirm whether your pleadings and remedies stay within that category.

Statute citation

The relevant framework is set out in the Limitation Act (Cap. 163).

For actions founded on a contract in writing, the general limitation period is typically 6 years, subject to:

• how and when the cause of action accrues, and
• any statutory exceptions or modifying rules that apply to your facts.

Use the calculator

DocketMath’s Statute of Limitations calculator estimates the deadline for a Singapore written contract claim using the core limitation period (typically 6 years under the Limitation Act (Cap. 163)).

Use the tool here: /tools/statute-of-limitations

Inputs to enter

1. Accrual date / breach date: the date the cause of action accrued (often tied to when payment became due and unpaid, or when performance became due and failed).
2. Claim type: select written contract so the calculator applies the 6-year baseline.

How outputs change with your inputs

• If your accrual date moves forward, the calculated deadline generally moves forward by the same amount.
• If you accidentally use the contract signing date instead of the accrual date, the deadline may look wrong (because signing date ≠ accrual date in many cases).
• If you select the wrong claim category, the calculator may apply a different baseline period, changing the result materially.

Checklist before you rely on the output

Gentle disclaimer: This is general information and an estimation tool, not legal advice. If the accrual date or exceptions are unclear, consider getting professional guidance.
