The family of deceased boxer Arturo Gatti was at the Montreal courthouse Monday asking a judge to review the former world boxing champion's will after his entire inheritance was left to his wife, Amanda Rodrigues and his children.

Gatti's family said the signed testament, drawn up on June 17 - three weeks before his death - is not valid. Gatti's fortune is estimated at several million dollars.

Rodrigues, 23, was arrested in Brazil in July after Gatti's body was found in an apartment he was renting in the beachfront town of Recife. He had died of choking via Rodrigues's purse strap, the autopsy showed. Rodrigues was release three weeks later, after Brazilian authorities declared the death a suicide.

Gatti's family refuses to believe claims his death was a suicide. In early August, they asked coroners in Montreal to perform a second autopsy on his body. The results are so far inconclusive.

Gatti, 37, had drawn up a will in 2007 in New Jersey that left his savings to his mother, Ida.

"The alleged document signed in New Jersey, is inexistent at this stage, so the only document we have - the only existing will, according to us - is the testament that was signed in Quebec before a notary in June." Said Pierre-Hugues Fortin, Rodrigues's lawyer.
