"Loan Facility This letter records the terms on which I, Douglas Watson Brown, have lent Phyllis Edna Clothier of 23 Parklands Ave, Groby, the sum of£200 per month on an ongoing basis. Once signed, this letter will create a legally binding agreement between the parties. The terms are as set out below. 1. Douglas Brown will make payments of£200 per month to Phyllis Clothier. 2. This amount may be varied at any time without notice by Douglas Brown. 3. The loan is to be secured by way of Phyllis Clothier providing Douglas Brown with the title deeds of the property owned and occupied by her. 4. Should Phyllis Clothier sell her property the loan will be repaid in full as a condition of returning the title deeds, if repayment is not possible then the outstanding balance will form a charge against the property in favour of Douglas Brown 5. Should Phyllis Clothier die before the loan is repaid, then the estate shall repay the loan in full plus any interest up until the date of the repayment. 6. The loan shall attract interest of 0.75% every month on the outstanding balance. For the avoidance of doubt please see appendix 1."
"The rules of law restricting the assignability of contracts are, however, by no means limited to contracts of personal service. In the case of contracts for the sale of goods, for example (unless the contract expressly or by implication covers the purchaser and his assigns), the seller is entitled to rely on the credit of the purchaser as to refuse to recognize any substitute. Similarly, the purchaser is entitled to rely upon the seller and hold him responsible for due performance."
"I may add that a possible confusion may arise from the use of the word ‘assignability’ in discussing some of the cases usually cited on this subject. Thus, in British Waggon Co and Parkgate Waggon Co v Lea the real point of the decision was that the contract which the Parkgate company had made with Lea for the repair of certain wagons did not call for the repairs being necessarily effected by the Parkgate company itself, but could be adequately performed by the Parkgate Company arranging with the British Waggon company that the latter should execute the repairs. Such a result was not dependent upon the assignment of contract at all. It depends on the view that the contract of repair was duly discharged by the Parkgate company by getting the repairs satisfactorily effected by a third party. In other words, the contract bound the Parkgate company to produce a result, not necessarily by its own efforts, but, if it preferred, by vicarious performance through a sub-contractor or otherwise."
