Pascoe v Turner

Pascoe v Turner [1979] 1 WLR 431 is an English land law case, a case of proprietary estoppel.
Facts.
The husband, was a fairly successful man of commerce and at all material times was and had been building up some capital assets which he invested in purchases of private and commercial property. After 10 years living in a house registered in his name with his wife, he left for a mistress. Soon he offered marriage, which she declined. They found a house in 1965 which he bought and he thereafter clearly assured her it would be hers. On the back of this she redecorated, buying carpets and curtains, improved and repaired, but there was never any written agreement or conveyance. Work she carried out and/or paid for:
Then there was a quarrel. He decided to throw her out of the house if he could. In April 1976 his solicitors wrote to her giving her two months notice "to determine her licence to occupy", and demanded possession in June 1976. She refused to go. 
In this action he sued her for possession of what he regarded as his legal home; she counterclaimed for an order to give effect that he held the house on trust for her (and her heirs and assigns absolutely) and that the contents of the house belonged to her. 
Judgment.
The Court of Appeal held the mistress occupied the house under a bare licence, and had received an imperfect gift of the house. No trust could be inferred, but the encouragement to improve the house in the belief it was hers created a proprietary estoppel. A mere licence can be defeated by a sale of the house, so to comply with equity the legal owner, her ex-cohabitee was ordered to execute a conveyance.
