Sir Paul McCartney's estranged wife Heather Mills has been forced to sell her home - after legal fees left her millions of dollars in debt. The 40-year-old will move back to her former residence in Brighton England, after selling her Robertsbridge, East Sussex country estate in order to collect the cash deposit of $1 million (GBP500,000) she put down on the property. That sum came from the sale of a converted barn given to her by the ex-Beatle after their split in May 2006. But the former model has not profited from the sale of her nine-bedroom mansion, as it sold for $6.5 million (GBP3.25 million) - the same price she paid six months ago for the home, which also boasts two staff cottages, horse stables and a gym. In an appearance on U.K. TV show GMTV last year (31Oct07), the glamour model-turned-activist admitted her divorce battle with MCCartney has left her $3 million (GBP1.5 million) in debt.
