The former STONE TEMPLE PILOTS singer's ex-wife Mary Forsberg filed court documents on Dec. 30 asking to be named the executor of Weiland's will (Weilandwas married to his third wife Jamie Wachtel at the time of his death). Forsberg also filed a copy of the will, written in April 2007, with his signature as proof, according to papers obtained by PEOPLE. 

 

Weiland had about $2 million to his estate, and also created a trust that has undisclosed assets. 

 

Forsberg, who was his second wife, is the mother of Weiland's two children Noah, 15, and Lucy, 13. The mother of two penned her memories of Weiland and their marriage as well as his drug abuse in her memoir called Fall to Pieces. She also wrote an emotional letter in Rolling Stone days following Weiland's death. "The truth is, like so many other kids, they lost their father years ago. What they truly lost on December 3rd was hope," she wrote with contributions from her kids. 

 

The former Velvet Revolver band member married his third wife Jamie Wachtel in 2013. Weiland's first wife is Janina Castenada, whom he was married to from 1994 - 2000. 

 

Weiland died at the age of 48 on Dec. 3 while on tour with his band The Wildabouts in Bloomington, Minnesota. The Hennepin County Medical Examiner's Office in Minnesota said a mix of cocaine, ethanol (alcohol), and MDA (a relative of ecstasy) led to the rock star's death. The press release, obtained by PEOPLE, also mentioned Weiland's history of cardiovascular disease, asthma, and multi-substance dependence as "significant conditions".
