Singer Courtney Love has been sued by a business management and accounting firm because she didn’t pay a share of profits after selling a portion of Nirvana’s publishing catalog. According to The Associated Press, Tuesday, the firm sued Courtney Love for about $1 million.

The widow of Nirvana singer Kurt Cobain should have paid the Los Angeles-based London & Co. $975,000, after she made an oral agreement that she would pay the company 5% of any of her earnings or those from The End of Music, her company. The five-page lawsuit claimed that the singer sold a portion of Nirvana’s publishing rights for $19.5 million, reported The Associated Press.

The End of Music was created to take care of Cobain’s intellectual property, including his career with Nirvana. Courtney Love has been managing most of the rights of Cobain’s and Nirvana’s work after the artist killed himself in 1994.

It is not sure if the lawsuit referred to the deal made in April, when Love unloaded 25 percent of her Nirvana holdings to Larry Mestel, founder of Primary Wave Music Publishing and former Virgin Records executive.

Courtney Love’s rep was not reached for comment.

Apparently Love initially controlled about 98 percent of Nirvana’s song catalog. The other members of the band and Universal Music Group had to fight the singer to receive the permission to release a greatest- hits album in 2002.

The lawsuit was filed Tuesday in Los Angeles Superior Court.
