Resolving Boundary Issues Caused by Digital Mapping Errors

Resolving boundary issues: How Mullins Treacy LLP Solicitors Can Help Resolve Uncertain Property Boundaries Caused by Digital Mapping Errors

Introduction

As property mapping in Ireland has moved from traditional paper-based plans to digital systems, many landowners have discovered that their registered boundaries no longer align accurately with fences, hedges, or site layouts on the ground. This misalignment often results from the digitisation process used by the Property Registration Authority (PRA), where hand-drawn maps were converted to modern coordinate grids, sometimes shifting boundaries by several metres.

When this occurs, planning applications, sales, or development projects can be delayed or challenged. A solicitor plays a crucial role in resolving these issues – by interpreting what your registered map legally represents, comparing it to historic deeds and surveys, and working with a qualified surveyor to produce corrected, PRA-compliant mapping.

At Mullins Treacy LLP Solicitors, we can liaise with the PRA or local planning authorities to rectify inaccuracies, protect your ownership rights, and ensure your property plans and boundaries are legally and practically aligned.

The Process

When property boundaries are unclear due to digital mapping errors, Mullins Treacy LLP Solicitors guide you through a structured process. We begin by reviewing your title deeds, planning documents, and historical maps to identify discrepancies.

Our team of specialist property solicitors then coordinate with a local surveyor to carry out an accurate boundary assessment. Once verified, we advise on legal options, negotiate with neighbours or authorities if needed, and can represent you in formal proceedings. This ensures clarity, security, and peace of mind over your property boundaries.

1. Interpret What the Registered Map Actually Means

At Mullins Treacy LLP Solicitors, we understand how Land Registry maps (Folio maps) work – and importantly, what they don’t represent:

• We know that Land Registry boundaries are “general boundaries”, not exact survey lines
• We can explain how your registered title (folio) and the digital map relate to the physical features on the ground – like hedges, fences, or walls.
• We can help you determine whether a discrepancy is just within normal tolerance, or something that needs correction.

2. Check Your Title Documents and Historical Maps

Our solicitors can:

• Review your folio and filed plan (official Land Registry documents).
• Compare these to old paper maps, deed maps, or Ordnance Survey maps from before digitisation.
• Identify whether the apparent error was introduced during the digital conversion process (a known issue when maps were scanned and georeferenced).
• If the digital map doesn’t match the legal description or old deeds, we can use that evidence to challenge or correct it.

3. Work with a Mapping or Land Survey Expert

While our team of solicitors deals with the legal side, we’ll often bring in:

• A chartered land surveyor or mapping consultant to take accurate GPS coordinates.
• The expert can prepare a map compliant with PRA requirements (e.g., ITM coordinates ^[1] ) to support a correction or boundary application.
• Our team will then formally use this as part of an application to rectify the boundary or lodge a Form 17 (Mapping Correction) with the Property Registration Authority (PRA).

4. Deal with Neighbour or Boundary Disputes

• If the boundary issue affects a neighbour (e.g., a hedge or fence now appears inside the “wrong” plot on the digital map):
• We can negotiate with the adjoining owner.
• If needed, we can lodge a Section 85 Land Registration Act 2006 application to the PRA for a determination of boundary.
• Our team handle the legal notices, consents, and affidavits that accompany such applications.

5. Rectify or Defend Your Title with the PRA

Our solicitors can formally request:

• A rectification of the register if the PRA made an error when digitising.
• A new filed plan if a boundary was misplaced.
• Or represent you if the PRA requires further clarification or objections arise.
• We know the PRA’s internal procedures and how to phrase correspondence to get traction.

6. Protect Your Position Before a Sale or Build

If you’re selling, buying, or planning development near a disputed or uncertain boundary:

• Our solicitors can ensure your contract and mapping are legally defensible.
• We’ll prevent you from selling land you don’t own (or vice versa) – a surprisingly common problem in rural areas with digitised mapping.
