Late Soundgarden singer Chris Cornell's widow and ex-wife are locked in a legal battle over the dispensation of his estate, which is estimated to be worth $20 million.

According to court documents obtained by The Blast, Vicky Cornell filed a petition to administer Chris’ estate following his death. She lists the sole beneficiaries of her husband's last will and testament, which was signed in 2004, as herself and the Cornell Family Trust. Vicky had two children with her husband, Toni and Christopher.

However, Cornell's first wife, Susan Silver, and the daughter they had together, Lillian, are claiming in court they are owed child support from a 2004 divorce settlement. Susan also believes she is owed a percentage of Cornell’s royalties. They want an accounting of the estate to determine just how much they are owed.

Vicky Cornell has objected to both claims and is seeking to dismiss them, but both parties are also apparently attempting to settle their issues outside of court. Some of the issues stem from college tuition payments for Lillian, who took a leave of absence from school without notifying the estate.

Chris Cornell committed suicide in May 2017 at the age of 52. He was honored last January with a tribute concert in Los Angeles, featuring performances from Metallica, Foo Fighters and many others, as well as members of Soundgarden and Cornell's other band, Audioslave.
