Statute of Limitations for Written Contract in Ireland

7 min read

Published March 22, 2026 • By DocketMath Team

Overview

In Ireland, the statute of limitations for a claim brought on a written contract sets a hard deadline for starting court proceedings. If you file after the limitation period expires, the defendant can raise a time-bar defence, which can prevent the court from granting the remedy you’re seeking.

This article focuses on the general limitation rule most commonly used for contract claims “founded on” simple contracts in writing (rather than claims based on deeds, specialty arrangements, or other specialized categories). It also flags practical “edge cases” that can change the timeline—especially where limitation can be paused, restarted, or extended by the facts of the dispute.

If you want a quick, consistent way to estimate dates, use DocketMath’s /tools/statute-of-limitations calculator. You’ll enter the key dates once, and the tool will compute the likely expiry date for the limitation period you select.

Note: This is not legal advice. Limitation rules can be fact-sensitive (for example, the exact cause of action date, whether a claim is framed as contract vs. something else, and whether any exceptions apply).

Limitation period

The baseline rule: 6 years for simple contracts in writing

For most written contract claims in Ireland, the limitation period is 6 years from when the cause of action accrues. Practically, that usually means the clock starts when:

  • the breach occurs (e.g., non-payment on a due date), or
  • the debtor’s performance becomes due and is not performed, or
  • the contract provides for an installment or demand and payment is missed.

If you issue proceedings after the 6-year period ends, the claim may be struck out or dismissed on limitation grounds (subject to any applicable exception).

How to pin down the “start date” (cause of action accrual)

Because limitation turns on timing, you should be able to answer the question:

  • When did the contract require performance, and was it missed?

Common examples:

  • Invoice due date missed: If an invoice was payable on 1 February 2020, and payment wasn’t made, a typical starting point is around that due date (or the date payment was contractually required).
  • Termination and final amount due: If the agreement required payment of a termination settlement “within 10 days,” the accrual may align with the date those days expired.
  • Installment contracts: Each missed installment can create its own accrual window; however, the overall limitation analysis still depends on how the claim is pleaded and what is being recovered.

What the output typically changes when key inputs move

DocketMath’s calculator is designed around the limitation mechanics. The most important inputs and their effect are:

  • Date breach/performance became due: Moving this date forward shifts the limitation expiry date forward by the same amount of time.
  • Date you plan to issue proceedings: If this falls after expiry, the calculator will flag it as likely time-barred under the selected scenario (unless an exception applies).
  • Scenario selection (written contract): Selecting the “written contract” path applies the 6-year period. Selecting another scenario (e.g., different claim types) would change the calculation.

Key exceptions

Irish limitation law includes exceptions and modifiers that can affect whether the standard 6-year clock applies cleanly. These exceptions often turn on documentary evidence and the precise facts.

1) Acknowledgment or actions that can restart or defeat the limitation defence

A defendant may be treated as acknowledging the debt or obligation in a way that affects limitation. In practice, this can arise where there is:

  • a written acknowledgment of the liability,
  • part payment connected to the same obligation,
  • correspondence or conduct that can be construed as acceptance of the debt.

Practical takeaway: gather communications (emails, letters, statements of account) and transaction history showing whether the debtor recognized the obligation within the limitation window.

2) Fraud, concealment, or deliberate wrongdoing

Where the claim involves conduct amounting to fraud or concealment, limitation outcomes can differ from the ordinary rule. Courts can treat the accrual and discoverability of the claim differently when the claimant could not reasonably have known the basis for the action due to misconduct.

Practical takeaway: if fraud or concealment is genuinely part of the case, document the timeline of when the facts were discovered and what prevented earlier knowledge.

3) Disability and special personal circumstances (narrow but real)

Certain claims may be subject to different timing rules where a claimant is under disability (for example, minority or incapacity) during the relevant period.

Practical takeaway: if any claimant’s personal circumstances are in play, the limitation analysis must be adjusted accordingly. Don’t assume a standard 6-year rule automatically applies without checking the scenario.

4) Claims that are not truly “written contract” claims

Not every claim involving a document is a straightforward “written contract” limitation scenario. For example:

  • negligence claims have different limitation rules,
  • claims framed under other statutory rights may follow different periods,
  • deed/specialty arrangements may fall outside the simple contract framework.

Pitfall: misclassifying the legal basis can lead you to compute the wrong deadline. The limitation period depends on the cause of action, not just the existence of a written document.

Warning: If the contract is unclear about payment triggers, milestones, or dispute mechanics, the “accrual date” can be contested. That contest can be decisive for limitation.

Statute citation

For written contract claims in Ireland (simple contracts in writing), the core limitation period is generally drawn from:

  • **Statute of Limitations (Ireland)
    • The relevant provision for actions on simple contracts is 6 years.

Because statute references can be technical (and can vary by consolidation and amendments), it’s critical that your scenario matches the statutory category the court would apply to the claim. DocketMath’s tool is built to align with the most common “written contract” limitation approach used in practice.

If you want the exact cite for the provision you’re relying on, verify against the current consolidated text used in your matter before filing—especially if your contract is atypical (e.g., deed, specialty, or mixed claims).

Use the calculator

Inputs to enter (and what they mean)

Typically, you’ll supply:

  • Contract type: select Written contract (Ireland)
  • Accrual/start date: the date the right to sue arose (often the due date missed or the breach date)
  • Proceedings date (or target date): the date you would issue proceedings (or the date you’re checking against)

How to interpret the result

The calculator will generally produce:

  • Calculated expiry date: the end of the 6-year limitation period for the selected scenario
  • Timeliness status: whether the proceedings date is before or after expiry

Example (illustrative)

  • Accrual date: 1 February 2020
  • Limitation period: 6 years
  • Expiry date computed: 1 February 2026 (subject to how the tool handles calendar-day conventions)

If you issue on 15 March 2026, the calculator will likely indicate the claim is outside the limitation period for a written contract scenario.

Adjusting for exceptions (how the tool helps)

The calculator can’t determine facts like fraud, concealment, or the legal effect of acknowledgments without inputs from your documents. What it can do is help you:

  • compute the baseline 6-year deadline first,
  • then compare that baseline against event dates that could matter for exceptions (e.g., acknowledgment dates, part payment dates, discovery dates).
