The estate of Michael Jackson has earned $310million since the singer's death in June.

The figure, which includes album sales, the concert film This Is It and other merchandise, was revealed in court papers.

The estate's administrators have used $159milllion to pay the singer's debts, which stood at more than $400million when he died, reports Reuters.

"Although there remain unresolved creditor claims, pending litigation and additional challenging business, tax and legal issues, and the estate is not yet in a condition to be closed, the executors have made substantial progress in reducing the estate's debt," the documents state.

The costs include a $900,000 payment to the cemetry where Jackson's body is interred.
