Short overview

This short overview is intended to summarise the case, issues and outcome so far as they are supported by the judgment.

AI confidence in this short overview: medium

This appeal concerned title to a short driveway (the Disputed Land). The First-tier Tribunal found that a lost 1960 conveyance did include the Disputed Land and that the appellants had not established adverse possession because they lacked exclusive possession and intention to possess for the required period. The appellants' later acts (mainly from 2019) were insufficient to found long possession, and the FTT accepted that omission from first registration could be explained by changed topography.

Ratio decidendi

This summary is intended to identify the ratio decidendi, meaning the legal reasons for deciding and the binding part of the decision.

AI confidence in this ratio decidendi summary: medium

The judgment treats key questions about the terms of a lost conveyance and competing title as primarily factual matters for the tribunal, requiring appellate courts to show caution and deference to FTT fact-findings. It also indicates that historic plan shading and changed physical topography can legitimately explain an omission from first registration, and that acts carried out after the relevant limitation period cannot establish the long period of possession necessary for adverse possession.

Obiter dicta

This summary is intended to identify obiter dicta, meaning observations made by the way that were not necessary to deciding the case and are not binding.

AI confidence in this obiter dicta summary: medium

The tribunal commented (obiter) that late disclosure and failure to seek specific disclosure during trial may undermine later applications for rehearing, and that commonplace, neighbourly shared use of a surface feature can make inferring exclusive possession difficult.
