Limitation of actions refers to the legally prescribed time limits within which a claimant must commence court proceedings, after which a claim becomes time-barred and generally cannot be pursued. In practice, it governs when civil claims in contract, tort/delict, personal injury, debt, property and other areas must be issued. The concept is given statutory effect: primarily the Limitation Act 1980 (England and Wales), the Prescription and Limitation (Scotland) Act 1973, the Limitation (Northern Ireland) Order 1989 and the Statute of Limitations 1957 (Ireland), each setting out specific limitation or prescription periods, rules on accrual of causes of action and provisions for postponement (for example, fraud, concealment, mistake, disability and latent damage). In England and Wales, Northern Ireland and Ireland, limitation is generally a procedural defence which must be pleaded, whereas in Scots law prescription can extinguish the underlying obligation. Limitation of actions is crucial in assessing claim viability, advising on pre‑action strategy, drafting proceedings, and evaluating settlement and litigation risk. Lawyers must identify the correct limitation or prescription period, consider any extension or suspension provisions, and diarise long-stop dates to avoid claims becoming irrecoverable.
