FACTBOX-The 'big three' divorce cases

By Jennifer Hill

LONDON (Reuters) - Three high profile divorce hearings are being heard in February.

Here are the details:

* Mills versus McCartney

Paul McCartney and Heather Mills are facing off in one of the biggest and most bitter divorce battles in showbusiness history this month -- with a slice of his Beatles fortune at stake.

Mills, the 40-year-old former model whose marriage to the pop icon lasted less than four years, represented herself in court after sacking her lawyers, albeit with the help of several friends.

McCartney, one of the founders of the world's most famous pop group, is worth an estimated 825 million pounds.

Legal experts believe Mills is asking for up to 50 million pounds from McCartney, 65, and that he may be prepared to offer only half that sum.

Financial provision for their daughter, Beatrice, 4, is likely to be a key consideration.
