Purpose - This paper aims to examine the remedies currently available in Ireland to resolve boundary disputes to assess the importance of the role played by adverse possession in this context. It also examines the potential impact of certain reforms in this area of law.Design/methodology/approach - The research methodology is primarily doctrinal, although a comparative approach is adopted for the purposes of assessing whether certain lessons can be learned from recent reforms to the English law on adverse possession and the Australian approach to resolving boundary disputes, which relies heavily on mistaken improver and building encroachment legislation.Findings - This paper demonstrates how the current law leaves certain mistaken improvers or encroachers on neighbouring land without a remedy, as they cannot rely on the doctrine of proprietary estoppel or adverse possession. If Ireland decides to replicate the English good faith requirement in relation to adverse possession of boundary land, the remedial vacuum facing these mistaken improvers or encroaching builders will become more pronounced. It is submitted that any such reform should be supplemented by the introduction of legislation akin to that operating in Australia which would facilitate the consideration of a broad range of factors and provide for flexible remedies to resolve such difficulties. It is also submitted that the legislation imposing such a good faith requirement should be carefully drafted to avoid the potential interpretative difficulties associated with the English reforms.Originality/value - Boundary disputes are an unfortunate fact of life. The prevalence of boundary disputes and high costs associated with boundary litigation makes this review and critique of the current law and potential reforms highly relevant.
