Denise Richards claims her ex-husband Charlie Sheen has not been paying his child support payments and that he owes $500,000 (NZ$775,000).
The New York Post says Richards has filed court documents against the Two and a Half Men actor for not paying his share of raising their two daughters, Sam, 15, and Lola, 14.
Richards, who stars in The Real Housewives of Beverly Hills, wants a judge to force her wayward ex-husband to cough up the dough.
"[Charlie] has squandered over $24,000,000 ($A37 million) from the sale in his interest in Two and a Half Men to pay his personal debts and to support his extravagant lifestyle at the expense of support payments for his children," read the papers, the Post obtained.
