LOS ANGELES – A business management and accounting firm sued Courtney Love for nearly $1 million on Tuesday, claiming she failed to pay them a share of profits from the sale of Nirvana's publishing catalog.

Love is the widow of Nirvana singer Kurt Cobain. The five-page lawsuit filed in Los Angeles Superior Court Tuesday afternoon claims she sold a portion of his share of Nirvana's publishing catalog for $19.5 million.

Los Angeles-based London & Co. alleges Love broke an oral contract to share 5 percent of any of her earnings or those from her company, The End of Music.

That company, according to the lawsuit, was created to manage Cobain's intellectual property, including his career with Nirvana.

London & Co. claims its share from the sale would have been $975,000.

Love controlled most of the rights to Cobain and Nirvana's work after his suicide in 1994.

The former Hole front woman sold a portion of her rights to Nirvana's publishing catalog in 2006. It was unclear late Tuesday whether that is the deal London & Co. is claiming a share of. The attorney who filed the suit did not immediately return a phone message left after hours Tuesday.

A phone message left for Love's publicist and an e-mail sent to her attorney were also not returned Tuesday evening.
