The mother of the late Alice in Chains singer Layne Staley is suing her son's former band over royalties.  According to the Seattle Post Intelligencer, a lawsuit was filed on May 2 in King County Superior Court.

Nancy McCallum, Staley's mother, is saying she is owed half of the money that Staley would've earned if he were alive and in the band.  That would be about 16 percent of the band's current income.

But, the band has attempted to cut her out of any further payment, except for the royalties from song that Staley wrote or co-wrote.  Most of Alice in Chains' music was written by guitarist Jerry Cantrell.  Cantrell and Staley split the lyric writing duties.

The band offered McCallum $341,000 to end their business relationship.  But, that is apparently much less than she has recieved since her son's death.

The band has also said that McCallum attempted to trademark the name "Alice in Chains."

Staley, Jerry Cantrell, Sean Kinney, and Mike Starr started Alice in Chains in 1987.  The band enjoyed multi-platinum success in the early 1990s.  But, they were mostly inactive throughout much of the second half of that decade, due to Staley's drug addiction.  Layne Staley died on April 5, 2002.
