“The intention of the 2011 order in broad terms was to give the wife money to purchase an alternative home,£2 million as a Duxbury fund, and pension provision by way of a clean break. No court would have expected her to forego maintenance for six years or pay for herself or to pay for her housing mortgage interest as a loan. It seems to me that the fair way forward in this case is to release her from the undertakings to repay the mortgage interest and the maintenance to the extent that she receives the original£1.3 million from the husband upon the sale of RG and£700,000 upon the sale of the Spanish property.”
