LOS ANGELES (AP) -- Documents state an agreement has been reached in a lawsuit involving Heath Ledger's $10 million life insurance policy. The filings seek to establish a court guardian to represent Ledger's 3-year-old daughter, Matilda Rose, who is the policy's beneficiary. An attorney has requested a closed hearing for late next month. An attorney for Ledger sued ReliaStar Life Insurance Co. last year, claiming the company was refusing to pay the actor's death benefits. The attorney claimed the insurer was refusing to pay because it wanted to investigate whether Ledger's death was a suicide. A coroner ruled Ledger's death last January was from an accidental prescription drug overdose. Calls to attorneys handling the case weren't immediately returned Thursday.
