Boundary & Fence Agreement (Ireland)

A Boundary & Fence Agreement in Ireland defines the rights, restrictions, and obligations attaching to a particular parcel of land and binds the owners who take it, and is governed by the Land and Conveyancing Law Reform Act 2009.

The LCLRA 2009 effected a thorough reform of the law of real property in Ireland, replacing much of the pre-1922 common law and statutory framework with a modern, accessible statutory code. Part 4 of the LCLRA 2009 deals with co-ownership and shared boundaries, and Part 8 deals with easements and profits à prendre — both of which are relevant to boundary and fence disputes. Section 2 of the LCLRA 2009 defines 'land' broadly to include all land, buildings, mines, minerals, and any estate, interest, or right in or over land, including boundary features such as walls and hedges.

The Registration of Title Act 1964 governs the registration of title to land in Ireland through the Land Registry (administered by the Property Registration Authority — PRA). For registered land (which now comprises the majority of land in Ireland following the completion of compulsory registration in all counties), boundaries are shown on the Land Registry map, but section 85 of the 1964 Act makes clear that the map is indicative only and not conclusive as to boundary positions. The Land Registration Rules 2012 (S.I. No. 483 of 2012) provide a procedure for registering a 'determined boundary' — a fixed boundary agreed by neighbouring owners — which becomes binding on successors in title.

Boundary disputes between neighbours are among the most common and most costly forms of property litigation in Ireland. Disputes arise from a variety of causes: ambiguous or missing title documents; physical changes to boundary features (removal or replacement of hedges, fences, or walls); encroachments by one owner onto the other's land; and claims of adverse possession under the Statute of Limitations 1957. The LCLRA 2009 and the Mediation Act 2017 both encourage the resolution of property disputes by agreement rather than litigation, and a written boundary agreement registered in the Land Registry provides the most durable solution.

Conveyancing practice in Ireland historically used 'T' marks on title maps to indicate ownership of boundary features — a 'T' mark on the inner side of a boundary on one owner's title map indicates that the boundary feature belongs to and must be maintained by that owner. However, T marks are not always present on older titles, and many deeds are silent on boundary maintenance obligations, leading to uncertainty and disputes. A written boundary and fence agreement supplements the title documentation and removes ambiguity.

Solicitors acting on property transactions in Ireland are required by the Law Society of Ireland's Conveyancing Committee guidelines to raise boundary queries with the seller's solicitor as a standard part of the requisitions on title process. Where a boundary issue is identified, the solicitor acting for the buyer will typically refuse to advise the client to proceed with a purchase until the boundary uncertainty is resolved, as it could affect the marketability of the property and the ability to obtain a mortgage. A Boundary and Fence Agreement prepared and executed before the sale, and lodged with the PRA as a determined boundary, can resolve the defect and allow the transaction to proceed without delay. For new residential developments, developers routinely establish boundaries between units by reference to the planning permission maps and the architectural drawings, and these boundary positions are recorded in the Land Registry folio maps for each individual property upon registration. Neighbouring landowners who identify a discrepancy between the physical boundary and the title map at any stage — whether on purchase, on planning a development, or following a survey — should engage a SCSI-registered chartered surveyor to prepare a report and a boundary map, and a solicitor to draft and register the appropriate boundary agreement.

An Irish Boundary and Fence Agreement is needed whenever neighbouring property owners wish to formally record the location of their common boundary, allocate ownership of and maintenance responsibility for boundary structures, resolve an existing boundary dispute, or prevent future disputes that might arise on a change of ownership or the passage of time.

You need a Boundary and Fence Agreement when you are: purchasing property and the boundary with the neighbouring property is uncertain, disputed, or not clearly shown on the title documents; erecting a new fence or wall on or near the boundary with a neighbouring property and want to record the agreed boundary line and each owner's rights and obligations in relation to the structure; replacing or repairing an existing boundary feature (such as an old hedge, stone wall, or timber fence) and want to agree with the neighbour on the type, location, and cost of the replacement; in dispute with a neighbour about the location of a boundary or the ownership or condition of a boundary structure, and want to resolve the dispute by agreement rather than litigation; selling or re-mortgaging property and the solicitor has identified a title defect or uncertainty relating to a boundary that must be resolved before the transaction can proceed; or planning to build an extension, erect a structure, or carry out landscaping works near the boundary and want to confirm the works do not encroach on the neighbour's land.

From the perspective of both property owners, a written boundary and fence agreement provides legal certainty and prevents future disputes. When a property changes hands, the new owner inherits all boundary disputes and uncertainties — a clear written agreement registered in the Land Registry binds future owners and provides a definitive record of the agreed boundary position.

For solicitors acting on property transactions, a title defect caused by a boundary dispute or uncertainty can delay or prevent a sale, as a purchaser's solicitor will typically refuse to advise the client to proceed with a purchase where a boundary is uncertain or disputed. A written boundary agreement executed by the current owners and registered in the Land Registry (as a determined boundary under the Land Registration Rules 2012) resolves the defect and supports the transaction.

For property developers, boundary clarity is essential at the planning and construction stage — uncertainty about boundaries can delay planning permission applications, cause disputes with neighbouring landowners during construction, and create title defects that affect the marketability of completed units.

Under the Residential Tenancies Act 2004 as amended by the Residential Tenancies (Amendment) Act 2019, the Residential Tenancies Board (RTB) registers all tenancies and adjudicates disputes. Section 12 of the Residential Tenancies Act 2004 sets landlord obligations. The Land and Conveyancing Law Reform Act 2009, Section 51, governs property transfers. The Property Registration Authority (PRA) maintains the Land Registry under the Registration of Title Act 1964.

A thorough Irish Boundary and Fence Agreement should contain the following key provisions to clearly define the boundary between neighbouring properties, allocate ownership of and maintenance responsibility for boundary structures, and provide for the resolution of future disputes.

The parties clause identifies both property owners by full name, address (including Eircode), and PPS number, and describes them as the 'Owner of Property A' and 'Owner of Property B' (or similar designations) for ease of reference throughout the agreement.

The property description clause identifies each property by its full address (including Eircode), folio number (for registered land), and the name of the county in which it is registered. It should also confirm that each owner is the registered owner of their respective property in the Land Registry.

The boundary demarcation clause is the most important provision in the agreement. It describes precisely where the boundary between the two properties runs, using measurements from fixed points (such as boundary posts, building corners, or road edges), references to the agreed survey plan (attached as an exhibit to the agreement), and — where appropriate — GPS coordinates of key boundary points. The clause should confirm that the boundary described in the agreement supersedes any earlier description in the title deeds where there is a conflict.

The survey plan exhibit consists of a detailed map or survey plan prepared by a SCSI-registered chartered surveyor, showing the agreed boundary line by reference to accurate measurements from fixed physical features. The plan must be signed by both owners and the surveyor, and a copy must be lodged with the PRA for registration as a determined boundary.

The boundary structures clause identifies each fence, wall, hedge, ditch, bank, or other structure that forms part of or lies adjacent to the boundary, describes the current condition of each structure, and records whether each structure is (a) located entirely on Property A, (b) located entirely on Property B, or (c) located on the boundary (a 'party structure'). For each structure, the clause states the respective ownership.

The maintenance and repair clause allocates responsibility for maintaining and repairing each boundary structure identified in the boundary structures clause. For structures owned by one party, that party is responsible for maintenance at their own cost. For party structures, the parties share maintenance costs equally (or in such other proportions as they agree) and must consult each other before undertaking significant works.

The planning and regulatory compliance clause addresses who is responsible for obtaining any planning permission required in connection with the replacement, alteration, or erection of boundary structures, and confirms that all works will be carried out in compliance with the Building Control Acts 1990 to 2014 and the Planning and Development Regulations 2001.

The Land Registry registration clause obliges both parties to cooperate in applying to the PRA for registration of the agreed boundary as a determined boundary under Rule 19 of the Land Registration Rules 2012, and to sign all documents required for that purpose. The costs of registration (PRA fees, surveyor's fees, and solicitor's fees) are to be shared equally.

The dispute resolution clause provides that any future dispute about the boundary or about the boundary structures shall first be referred to mediation under the Mediation Act 2017 before either party may bring court proceedings, and nominates a SCSI-registered surveyor as the expert to determine any technical dispute about the precise location of the boundary.
