Charlie Sheen's anniversary payment

May 5, 2010, 9:30 GMT

Charlie Sheen pays wife Brooke Mueller $300,000 for every year they are married, according to the pre-nuptial agreement they signed.

The couple - whose marriage has been on the rocks since Charlie was arrested on Christmas Day (25.12.09) following allegations he threatened to kill Brooke - agreed to the deal before they tied the knot in May 2008 and the payment is valid for the first 10 years of marriage.

If they divorce before then and between anniversaries, the money will be divided according to time.

The document, which was obtained by website Gawker, stated: "Charlie shall pay to Brooke... the annual sum of $300,000 (the 'Anniversary Payment'), payable within 30 days of the anniversary of marriage."

Brooke can send Charlie a notice of default if he fails to pay and the payment will accrue interest.

Within the first 180 days of their marriage, Brooke received $500,000 and received stakes in Charlie's homes and if they do decide to divorce she will be given a $100,000 relocation fee and whichever of the actor's cars she is currently driving.

Charlie - who has 13-month-old twin sons, Max and Bob, with Brooke - also has to pay all of his spouse's living expenses.

However, Brooke will not be able to stake a claim in Charlie's hit TV show 'Two and a Half Men', something which his ex-wife Denise Richards already has a stake in.

The document read: "Such gross income received is subject to commission expense, other business expenses, income taxes and certain provisions of an agreement pending finalisation between Mr. Sheen and his ex-wife."

Although the couple are currently living apart, they recently said they had no plans to divorce and wanted to save their marriage for the sake of Max and Bob.

In March, Charlie, 44, pleaded not guilty to assaulting Brooke as he faces three charges - felony menacing, misdemeanour third degree assault and misdemeanour criminal mischief - stemming from her allegations he threatened to kill her with a knife. A trial date has been set for July 21.

Both Charlie and Brooke have been in rehab since the allegations receiving treatment for their respective addictions.
