Madonna and Guy Ritchie are due to be divorced at the high court in London tomorrow.

The couple announced last month that their seven-year marriage was over, and the case is listed for a "quickie" divorce under the names Ciccone M L v Ritchie G S.

Madonna, 50, and film director Ritchie, 40, are entitled to attend the 10am hearing before a judge in the high court family division but are not expected to do so.

Ritchie, who is believed to be worth £30m, is reported to have no desire to seek any of Madonna's estimated £300m fortune. Access to the couple's children was said to be Ritchie's primary concern, a source told the Evening Standard.

It is believed that the couple's two boys, eight-year-old Rocco and adopted David Banda, three, will split their time between Britain and the US while Madonna's daughter from a previous relationship, 12-year-old Lourdes, will stay with her.

Also today Slavica Ecclestone, the wife of Formula One mogul Bernie, filed for divorce. Ecclestone is estimated to have a personal fortune of £2.4bn, according to this year's Sunday Times Rich List, which could put his wife in line for a record divorce payout.

Slavica Ecclestone, a former model from Croatia and the mother of their two daughters, is already one of Britain's richest women.

She has engaged divorce lawyer Liz Vernon, who made headlines in 2004 when she secured a third of Arsenal and England footballer Ray Parlour's future earnings for his ex-wife Karen for a four-year period.

A spokeswoman for Slavica Ecclestone said today's announcement had been prompted by media speculation about the couple's personal life. They met in the early 1980s at the Italian Grand Prix, where Slavica, who is 28 years her husband's junior, was modelling T-shirts for Armani.

The highest divorce payout ever awarded by a British court was the £48m made to Beverley Charman in 2006 after her 28-year marriage to insurance broker John Charman.

The couple had total assets of £131m. Beverley Charman refused her husband's initial offer of £20m.
