The dispute apparently traces back to seven unreleased songs, according to TMZ.
The legal documents reportedly describe an "unlawful attempt to strong-arm Chris' Estate into turning over certain audio recordings created by Chris before he passed away." Vicky Cornell says the songs, which appear to be among her late husband's final recordings, were "solely authored by Chris; contain Chris' own vocal tracks; and were bequeathed to Chris' Estate" for the benefit of his family.
