Public rights of way are a defining feature of the English and Welsh countryside. They provide access across private land for walkers, riders and, in some cases, vehicular users. Whilst many landowners assume that the legal position is determined solely by the rights of way shown on the Definitive Map and Statement, the reality is considerably more complex. Historical public rights may continue to exist even where they are not recorded on the Definitive Map, creating significant risks for owners, developers and lenders dealing with rural land.

The Definitive Map: Conclusive, But Not Comprehensive

The Definitive Map and Statement maintained by local highway authorities is often described as the legal record of public rights of way. Section 56 of the Wildlife and Countryside Act 1981 provides that the Definitive Map is conclusive evidence of the existence of the rights shown upon it.

However, what is frequently overlooked is that the map is generally not conclusive evidence that no other public rights exist. A route omitted from the Definitive Map may nevertheless remain a public highway if sufficient evidence can be produced to establish its existence.

The origins of this issue lie in the creation of Definitive Maps following the National Parks and Access to the Countryside Act 1949. The surveying process was extensive but far from perfect. Many historical routes were overlooked, disputed or simply omitted. In some cases, local knowledge was lost before claims could be made. Consequently, there remains a substantial body of potentially unrecorded public rights across rural England and Wales.

Establishing Historical Rights

Historical public rights of way may arise through several mechanisms.

1. Firstly, a route may have been expressly dedicated as a highway centuries ago through deeds, inclosure awards, tithe records or other documentary evidence.
2. Secondly, rights may have arisen through presumed dedication. Under section 31 of the Highways Act 1980, uninterrupted public use of a route “as of right” for a period of 20 years can give rise to a presumption that the landowner intended to dedicate it as a highway.
3. Thirdly, rights may be established at common law where long public use, together with evidence of acquiescence by the landowner, supports an inference of dedication.

Claims for modification of the Definitive Map frequently rely upon historical documentary sources. Parish records, Ordnance Survey maps, estate plans, Finance Act 1910 records and old highway surveys may all be used to demonstrate that a route historically carried public rights.

The Continuing Threat of Unrecorded Routes

For rural landowners, the principal difficulty is uncertainty.

A title investigation may reveal no registered easements and the Definitive Map may show no public rights crossing the land. Nevertheless, a local user group, parish council or access organisation may later uncover evidence suggesting that a historical route exists.

Where sufficient evidence is produced, an application may be made for a Definitive Map Modification Order (“DMMO”). If successful, a previously unrecorded footpath, bridleway or restricted byway may suddenly appear across land that has been treated as private for decades.

The consequences can be significant. Agricultural operations may be disrupted, development opportunities constrained and property values affected. Landowners who have fenced, cultivated or built over a route may face enforcement issues or pressure to restore public access.

The risk is particularly acute in relation to strategic development sites on the edge of settlements where historical routes can interfere with site layouts, access roads and housing schemes.

The 2031 Deadline and Its Legacy

The Countryside and Rights of Way Act 2000 introduced a mechanism intended to address the backlog of historical claims. The legislation originally contemplated a cut-off date of 1 January 2026, after which certain historical rights of way predating 1949 would be extinguished if not recorded.

However, implementation has been delayed and transitional arrangements continue to evolve. Although the policy objective remains to provide greater certainty, the anticipated “closing of the books” has not yet delivered the finality many landowners hoped for.

As a result, historical claims remain a live issue. Local authorities continue to receive DMMO applications based on archival research, and volunteer organisations have undertaken extensive projects to identify potentially omitted routes.

Practical Risks for Landowners

Landowners should be cautious about assuming that the absence of a route from the Definitive Map eliminates all risk.

Due diligence for rural transactions should include a review of historical mapping and available documentary evidence, particularly where development is contemplated. Developers and lenders increasingly seek specialist rights of way searches and advice where land has significant strategic value.

Landowners should also be alert to public use of informal paths. Although not every worn track will become a highway, prolonged and unchallenged public use may support future claims for presumed dedication. Appropriate signage, permissive path agreements and periodic challenges to unauthorised use may assist in preventing new rights from arising.

Where there is a credible risk that a historical route could be the subject of a modification application, landowners may wish to consider whether a pre-emptive application for a diversion or stopping-up order is appropriate. In some cases, taking proactive steps to regularise or relocate a potential route can offer a greater degree of control than responding reactively to a DMMO. However, such an approach is not without risk. Initiating a diversion or closure process may bring the existence of a potentially claimable historical route into focus and alert third parties to evidence that might otherwise have remained untested. Careful strategic consideration is therefore required in each case. Specialist advice is essential both in assessing the strength of any underlying historical evidence and in determining whether the potential benefits of pre-emptive action outweigh the risk of effectively prompting a claim.

Where a potential historical route is identified, early investigation is often preferable to waiting for a formal modification application. Understanding the strength of the evidence can inform commercial decisions, development design and negotiations with local authorities.

Conclusion

The Definitive Map remains the cornerstone of the public rights of way system, but it is not an infallible or exhaustive record. Historical highways may continue to exist despite their absence from the map, and the process of uncovering and recording such routes remains active.

For rural landowners, this creates an enduring tension between certainty of ownership and the preservation of historical public access. The risk is not merely theoretical. Unrecorded rights can emerge many decades after land has been acquired, potentially affecting agricultural management, development potential and property value.

Until the law achieves greater finality regarding historical claims, prudent landowners, developers and advisers must continue to treat the absence of a route from the Definitive Map as the beginning of the enquiry rather than the end of it.

FAQs

Can a public right of way exist if it is not on the Definitive Map?

Yes. In England and Wales, the Definitive Map is conclusive evidence that a recorded right of way exists, but it is not conclusive that no other rights exist. Unrecorded routes may still be legally valid if supported by sufficient historical or user evidence.

What is a Definitive Map Modification Order (DMMO)?

A DMMO is a legal process used to amend the Definitive Map and Statement. Applications can be made to add, upgrade, downgrade or remove a public right of way based on evidence such as historical records or long-term public use.

How can historical rights of way be proven?

Historical rights may be established through documentary evidence such as:

• Inclosure awards
• Tithe maps
• Ordnance Survey mapping
• Estate records
• Finance Act 1910 documents

They may also arise through long-term public use under section 31 of the Highways Act 1980.

What risks do unrecorded rights of way pose to landowners or developers?

Unrecorded routes can:

• Disrupt development layouts
• Reduce land value
• Lead to enforcement action
• Require reinstatement of access

These risks often arise unexpectedly, even where no right is shown on the Definitive Map.

How can landowners prevent new public rights of way from arising?

Landowners can take proactive steps such as:

• Displaying clear signage (e.g. “Private – no public right of way”)
• Challenging unauthorised use periodically
• Entering permissive path agreements

Legal advice should be sought to ensure compliance and effectiveness.

What is the 2031 deadline for historical rights of way?

Current legislation aims to introduce a cut-off date (now expected in 2031) after which certain unrecorded pre-1949 rights may be extinguished if not added to the Definitive Map. However, the rules are complex and transitional provisions apply.

Should I investigate potential rights of way before buying or developing land?

Yes. Specialist rights of way searches and legal advice are strongly recommended for rural or development land in England and Wales. Early investigation can identify risks and inform design, valuation and negotiation strategies.
