Why some Right to Light claims fail before they even start
Before you sue, check your title. We expose the common pitfalls, Consent, Unity of Seisin, and Light Obstruction Notices, that kill claims instantly.
Why some Right to Light claims fail before they even start
It is very easy to spend money on modelling and letters, only to discover the claim was never viable. The smart first step is often a title and acquisition check, not a 3D model.
Here are the common early failure points.
1) You never acquired the right
Most rights of light are acquired by long use under section 3 of the Prescription Act 1832, which requires 20 years’ enjoyment, without interruption, and not enjoyed by written consent.
If your key windows are newer than you think, or the relevant period cannot be proved, the claim can fail at the first hurdle.
2) Your documents contain written consent
Section 3 makes written consent a direct bar to acquiring a prescriptive right.
This comes up in leases and estate documents where development is permitted, or where the drafting effectively amounts to written consent to the passage of light.
3) Unity of ownership, you cannot have an easement over your own land
A basic principle is that you cannot acquire an easement against yourself. Michael Barnes KC discusses the fee simple rule and the way unity of ownership or possession affects prescription in rights of light, with particular rules depending on whether the claim is under the 1832 Act or lost modern grant.
4) A Light Obstruction Notice has interrupted the clock
A Light Obstruction Notice (LON) under the Rights of Light Act 1959 creates a notional obstruction for one year, designed to interrupt prescription.
Two practical points really matter:
- If you want to challenge a LON, proceedings must generally be issued within one year of registration.
- If a prescriptive right had already been acquired under section 3, failure to challenge within the year can, in some circumstances, destroy the ability to rely on that right under the Act.
This is why checking the Local Land Charges register can be critical.
5) Your building has changed, and the window history is not what you think
Rights of light are tied to apertures in buildings. If windows have been permanently blocked up, or the structure has been altered so the benefit of the right is effectively abandoned, that can change the landscape. Michael Barnes KC explains how abandonment and alteration can affect the position, and why these questions can be fact sensitive.
6) Lost modern grant is not a simple fallback
If a strict 1832 Act case is difficult, lawyers may look at lost modern grant. But Michael Barnes KC makes clear that the interaction between lost modern grant and the 1959 Act can be complex, and it is not a casual alternative route.
Practical early checks before you spend money
- Review title and lease documents for written consent or development clauses.
- Build a window timeline, when were key apertures created or altered.
- Search Local Land Charges for Light Obstruction Notices.
- Only then commission heavier modelling if the claim clears these hurdles.
