"Time limit for actions to recover land. 15.

"Accrual of right of action in case of present interests in land 1. Where the person bringing an action to recover land, or some person through whom he claims, has been in possession of the land, and has while entitled to the land been dispossessed or discontinued his possession, the right of action shall be treated as having accrued on the date of the dispossession or discontinuance. ..… Accrual of right of action in case of future interests ..… 5(1) Subject to sub-paragraph (2) below, a tenancy from year to year or other period, without a lease in writing, shall for the purposes of this Act be treated as being determined at the expiration of the first year or other period; and accordingly the right of action of the person entitled to the land subject to the tenancy shall be treated as having accrued at the date on which in accordance with this sub-paragraph the tenancy is determined. (2) Where any rent has subsequently been received in respect of the tenancy, the right of action shall be treated as having accrued on the date of the last receipt of rent. ..… Right of action not to accrue or continue unless there is adverse possession 8(1) No right of action to recover land shall be treated as accruing unless the land is in the possession of some person in whose favour the period of limitation can run (referred to below in this paragraph as "adverse possession"); and where under the preceding provisions of this Schedule any such right of action is treated as accruing on a certain date and no person is in adverse possession on that date, the right of action shall not be treated as accruing unless and until adverse possession is taken of the land. (2) Where a right of action to recover land has accrued and after its accrual, before the right is barred, the land ceases to be in adverse possession, the right of action shall no longer be treated as having accrued and no fresh right of action shall be treated as accruing unless and until the land is again taken into adverse possession. ..… "
“134. Estoppel by convention arises out of an agreed statement of facts or law, the truth of which has been assumed by convention of the parties as a basis of their relationship. When the parties have so acted in their relationship upon the agreed assumption that the given state of facts or law is to be accepted between them as true, that it would be unfair on one for the other to resile from the agreed assumption, then he will be entitled to appropriate relief: see Spencer Bower on Estoppel by Representation (4th ed.) page 180. Commonly, such an estoppel arises where parties contract together on terms which mean one thing, but then conduct their relationship under that contract by reference to a subsequently formed convention between them that it means something else: see for example Amalgamated Investment and Property Co Limited v. Texas Commerce International Bank Limited[1982] QB 84 . 135. Estoppel by convention may nonetheless arise otherwise than in a contractual context: see for example Commissioners for Her Majesty's Revenue and Customs v. Benchdollar Limited[2010] 1 All ER 174 , in which a convention was established between HMRC and a number of persons alleged to be liable for employers' NIC to the effect that a certain course of conduct was effective to prevent time running against HMRC under the Limitation Acts, when in law it was not. 136. In the present case, counsel were content to accept, subject to one small adjustment proposed by Mr Spink, the summary of the relevant principles in paragraph 52 of my judgment in Benchdollar, after a review of the relevant authorities….. The summary is as follows: "…. the principles applicable to the assertion of an estoppel by convention arising out of non-contractual dealings, to be derived from Keen v. Holland, and the cases which comment upon it, are as follows: i) It is not enough that the common assumption upon which the estoppel is based is merely understood by the parties in the same way. It must be expressly shared between them. ii) The expression of the common assumption by the party alleged to be estopped must be such that he may properly be said to have assumed some element of responsibility for it, in the sense of conveying to the other party an understanding that he expected the other party to rely upon it. iii) The person alleging the estoppel must in fact have relied upon the common assumption, to a sufficient extent, rather than merely upon his own independent view of the matter. iv) That reliance must have occurred in connection with some subsequent mutual dealing between the parties. v) Some detriment must thereby have been suffered by the person alleging the estoppel, or benefit thereby have been conferred upon the person alleged to be estopped, sufficient to make it unjust or unconscionable for the latter to assert the true legal (or factual) position." 137. Mr Spink's suggested adjustment was to part (i) of that summary, where I suggested that the common assumption must be "expressly shared between them". Mr Spink submitted that the crossing of the line between the parties may consist either of words, or conduct from which the necessary sharing can properly be inferred, relying on note 2 at page 180 of Spencer Bower (op. cit.) and The August Leonhardt[1985] 2 Lloyd's Rep 28 at 34-5. I accept that submission.”
“Estoppel by convention may arise where both parties to a transaction “act on assumed state of facts or law, the assumption being either shared by both or made by one and acquiesced in by the other”
“….[the Probate Judge] cannot be said, by virtue of the language of section 9 of the Administration of estates Act 1925 to be a trustee within the meaning of that word for any of the purposes of theTrustee Act 1925 . He has no duties whatsoever to perform. No obligations fall upon him. It is a mere matter of necessary convenience and protection which has led to the introduction of section 9….; and although reference is made to the ordinary, the position of [the Probate Judge] appears to me to be different from the position of the ordinary The title of the diocesan bishop of the place where the property in question was situated; the name was used to distinguish the bishop’s exercise of the Church’s jurisdiction in cases of intestacy from his extraordinary or peculiar jurisdiction (see Dyke v Walford[1846] 13 ER 557 at page 578). , in that, whereas the ordinary had, at any rate in later times, thrown upon him the obligation to discharge debts before holding the balance to pious uses, no such obligation is thrown on [the Probate Judge]. The whole operation of that section is that where the condition is fulfilled of a person dying intestate, his estate, real and personal, vests in [the Probate Judge], and that property remains vested in him until the second condition is fulfilled, namely that administration is granted in respect of that property.”
