How do party wall disputes work under Irish property law?

What the Law Says

Unlike England and Wales, Ireland has no statutory party wall regime. Instead, rights and obligations concerning shared walls are governed by common law doctrines—including nuisance (unlawful interference with use or enjoyment of land), trespass (physical encroachment), negligence (failure to maintain causing damage), and easements (e.g., right to support). Section 35 of the Civil Liability Act 1961 imposes liability for damage caused by failure to maintain a structure that supports adjoining land or buildings. The Law of Property Act 1925 (as applied in Ireland via the Application of English Law Act 1878 and subsequent jurisprudence) informs principles of implied easements of support, though these are strictly construed. Courts determine rights based on title deeds, historical usage, and evidence of long-standing mutual benefit or necessity.

Practical Steps

First, review your title deeds and any registered burdens on the folio at the Property Registration Authority (PRA) — these may expressly grant or restrict rights over the party wall. If works are proposed (e.g., cutting into the wall for structural alterations), obtain written consent from the adjoining owner; absence of consent risks claims in trespass or nuisance. Engage a qualified building surveyor or structural engineer to assess impact and document pre-existing conditions. If a dispute arises, attempt resolution via mediation (e.g., through the Legal Services Regulatory Authority’s approved mediators) before issuing proceedings. For urgent matters involving imminent risk of collapse or damage, apply ex parte to the Circuit or High Court for an interim injunction under Order 84 of the Rules of the Superior Courts.
