A divorcing wife who made legal history when she was awarded a £250,000-a-year payout from her husband has won a 40 per cent increase in her maintenance payments.

Julia McFarlane, 49, who separated from her husband Kenneth in 2000, will receive £350,000 a year even her needs have been put at £150,000.

The new High Court ruling means that she will share in her former husband’s increased income, which has risen from £750,000 at the time of the divorce award to £1.1 million after tax. The award will be reviewed in 2015 when he plans to retire aged 55.

Mrs McFarlane won £250,000 annual maintenance in the House of Lords in 2006, as well as about £3 million in capital for her contribution to her husband’s career — as a wife and mother of their three children.

A City solicitor who had worked with Freshfields, she had given up her career to look after the children. The settlement partly compensated her for lost opportunities while her husband pursued a successful career as an accountant with Deloitte.

She returned to court earlier this year, initially for increased maintenance for the children, but then also to increase her own payments.
