1. I regret to say that in order for this agreement you made with the father to bind the son, who is his successor in title, the original agreement would have had to have been in writing and if necessary registered against your neighbour's folio. This is because the Statute of Frauds provides that all agreements in relation to property must be in writing in order to be valid. Here in order to be able to bind the son you would have needed to reduce the agreement with the father to writing and to have registered it against his folio in the Land Registry. Otherwise, an agreement restricting the development rights of your neighbour's property is not valid. So here the oral agreement is no longer enforceable as the party who agreed with you is now dead. It does not bind anyone else unless it was reduced to writing.
