Land Registry Maps Ireland: A Complete Guide to Property Boundaries

Everything you need to know about Land Registry maps in Ireland, the General Boundaries Rule, and how to define your property boundaries in Dublin and beyond.

Dublish ·

When buying or selling property in Ireland, the “red line” on the map is often the source of most confusion. Many homeowners assume that the Land Registry map is a definitive legal record of exactly where their property ends and their neighbour’s begins.

In reality, Irish land law operates under a very different principle: the General Boundaries Rule.

In this guide, we’ll break down what Land Registry maps actually show, why they aren’t always conclusive, and how to protect your interests if you’re dealing with a boundary dispute or a new registration in Dublin.

What is the Land Registry?

In Ireland, property ownership is managed by the Property Registration Authority (PRA). They maintain two distinct systems:

  1. The Land Registry: A digital register where ownership (the “folio”) and boundaries are mapped. Most property in Ireland is now registered here.
  2. The Registry of Deeds: An older system for unregistered land where physical deeds are filed.

If your property is in the Land Registry, you will have a Folio Number. This folio is the state-guaranteed record of who owns the land, any mortgages against it, and any rights of way (easements) that affect it.

The General Boundaries Rule

The most important thing to understand about Land Registry maps in Ireland is that they do not guarantee the precise location of a boundary.

Under the “General Boundaries Rule,” the red line on a Land Registry map indicates the approximate extent of the property for identification purposes only. It does not define whether the boundary is the centre of a hedge, the outer face of a wall, or two feet behind a fence.

Why does this rule exist?

The Land Registry map is based on Ordnance Survey Ireland (OSI) mapping. These maps show physical features (walls, fences, kerbs) but do not account for the legal nuances of ownership that may have been established in decades-old deeds.

How Boundaries are Decided in Disputes

If you and your neighbour disagree on where a boundary lies, the Land Registry map is actually the least important piece of evidence. Irish courts generally follow this hierarchy:

  1. Primary Evidence: The original Title Deeds and “Deed Maps” from when the property was first carved out or sold. These often contain specific measurements (e.g., “70 feet from the kerb”).
  2. Secondary Evidence: Physical features on the ground. Long-established walls, mature hedges, and fences that have been in place for years carry significant weight.
  3. Tertiary Evidence: The Land Registry map. This is used primarily to identify the plot, not to settle a dispute over a few inches of land.

Land Registry Compliant Maps

If you are registering a property for the first time, or “splitting” a site to sell a portion of your garden, the PRA requires a Land Registry Compliant Map.

Unlike a standard OS map, this must be prepared by a qualified professional (usually a Chartered Land Surveyor or an Architect). They will:

  • Physically visit the site.
  • Measure the boundaries against physical markers.
  • Ensure the map meets the PRA’s strict technical specifications for scale and accuracy.

In Dublin’s dense urban areas, where every centimetre counts, getting a professional survey is essential to avoid “mapping overlaps” that can stall a sale for months.

Accessing Maps: LandDirect.ie

If you want to see the map for your property or a neighbour’s, you can use the official portal: www.landdirect.ie.

For a small fee (usually around €5 for a view and €40 for an official copy), you can:

  • Search by address or Folio number.
  • View the “Title Plan” (the map).
  • Order a certified copy of the Folio.

Can you make a boundary “Conclusive”?

Yes, but it’s rare. Under Rule 41 of the Land Registration Rules, you can apply to have a boundary “formally determined” and made conclusive.

This requires:

  • An extremely high-accuracy map.
  • A formal agreement signed by both adjoining landowners.
  • An application to the PRA.

Most people don’t do this because of the cost and the difficulty of getting neighbours to sign a legal document. Instead, most Irish property owners rely on the physical boundaries (walls and fences) and the “General Boundaries” status.

Summary Checklist for Homeowners

  • Know your Folio: If you don’t know your folio number, find it on LandDirect.ie.
  • Check physical vs. mapped: Does your garden wall roughly match the red line on the map? If there’s a massive discrepancy, talk to a solicitor before selling.
  • Don’t rely on the red line for extensions: If you’re building a wall or an extension right on the boundary, hire a surveyor. Don’t just scale off a Land Registry map.
  • First Registration: If your house is old and “unregistered” (Registry of Deeds), you will need a compliant map when you eventually sell or mortgage it.
