"It is further hereby agreed and declared that the division garden walls or fences (if any) on the North and South sides of the piece of land hereby conveyed shall be party walls or fences and maintainable accordingly and shall be erected to the approval of the Architects of the Vendor as to one-half of the thickness thereof on the property hereby conveyed and as to the other half thereof on the adjoining land now formerly of the Vendor."
"the dividing garden wall or fence (if any) on the North side of the said property and the wall on the South side thereof shall be party walls or fences and maintainable accordingly and any wall or fence on the North shall be erected to the approval of the Architects of the Vendor as to the one half of the thickness thereof on the said piece of land hereby conveyed and as to the other one half thereof on the adjoining land."
"The clear intention, therefore, in my judgment, was that the party wall or fence erected between the two properties was intended to be a party wall owned by both parties. Originally, it seems there was in fact a wooden fence between the properties and there is little dispute but that that was a party fence, but that fence was eventually removed and in about 1979 the defendant erected a wall which we can now see in the various photographs and plans, about 6 or 9 inches behind the line of the fence, and he regarded that as his wall.
"... in order to ascertain whether the defendant has trespassed on the plaintiffs' land, or indeed pruned trees excessively, it seems to me necessary first to ascertain where the boundary between the premises is. In my judgment, the clear intention of Clause 4, and of the parties who lived on both sides up until 1979 at any rate, was that the fence was the party wall, and whilst I accept that the defendant deliberately built his wall inside the fence line, he must have been aware of the provision of Clause 4 because it appears in his own title or document of title, which is at page 71 in the bundle, and he decided to build this wall without, as I say, any consultation with his neighbours."
"The defendant says that he pruned the trees back to where he believed the boundary was. Well, I accept that evidence. It seems to me that is correct but, unhappily for the defendant, the boundary, as I find it, is not where he thought it was. Consequently, I do find that the defendant trespassed onto the plaintiffs' property and was not entitled to use the remedy of self-help as he claimed he was doing."
"The plaintiff and defendant were neighbouring owners of two of the three parts into which a house and grounds had been divided and a dispute arose as to the boundary line between their two gardens. The plaintiff claimed that the line ran between two points A and B, on a plan (the `purple' line) and that this would be found to be so on a true construction of the conveyance to him, supported by the respective conveyances to the predecessor of the defendant and to the owner of the third part of the house and grounds, the plaintiff contending that the conveyances were admissible evidence because of possible admissions therein against the common vendor's interests and because of the doctrine of contemporanea expositio . The plaintiff also relied on an oral agreement between himself and the personal representatives of the defendant's predecessor defining the boundary line."
"... on the evidence, there was an agreement between the plaintiff and the defendant's predecessor which was for a boundary along the `purple' line, and since this supported the conclusion already reached on the true construction of the plaintiff's conveyance, the plaintiff would succeed on his alternative claim based on the boundary agreement."
"Has, then, anything happened to alter or confirm this position? I turn to the alleged boundary agreement of September 29, 1960. In brief, this arose out of the preparations for the sale of Brooklands No. 1 made by Mr Shorthouse's executor. A Mr Burn, employed by agents for the executor, came to the not surprising conclusion that some steps ought to be taken to define the boundaries of Brooklands No. 1 before putting it up to auction. He accordingly obtained instructions to visit the property and agree the boundaries on behalf of the executor; and it has not been suggested that Mr Burn lacked authority to make a boundary agreement binding on the executor. Having examined the conveyances and the other documents, he visited Brooklands with an assistant, Mr Thomas, and proceeded to stake out the boundaries.
"... I hold that the plaintiff nevertheless succeeds on his alternative claim based on the boundary agreement."
"Now a boundary agreement may constitute a contract to convey land. The parties may agree that in return for a concession by A in one place, straightening the line of division, B will make a concession in another place; and the agreement may thus be one for the conveyance of land."
"In this case, the boundary on the conveyance, as I have construed it, coincides with the boundary on the agreement, and so the agreement is not registerable. If the two boundaries had not coincided, because, for example, the true construction of the conveyance yields a different boundary, then the agreement would have been an agreement whereby in fact it was agreed that land belonging to one should thenceforward belong to the other."
