Arturo Gatti's younger brother says he's fighting over the late boxer's estate because he wants to make sure his niece and nephew get the money.

Fabrizio Gatti testified at a civil trial in Montreal on Monday that he doesn't want any money for himself.

The Gatti clan and Amanda Rodrigues, the boxer's widow, are in a bitter dispute over who should get his $3.4-million fortune. Rodrigues has a will signed in Quebec just three weeks before Gatti's 2009 death that leaves everything to her and cuts out his daughter from a previous relationship.

The Gatti family contends a 2007 will drafted in New Jersey that leaves the estate to his mother and daughter Sofia should be recognized.

But nobody can find a signed copy of that will.

The family is also disputing the theory that Gatti committed suicide while on vacation in Brazil.  

Fabrizio Gatti says he and his family saw Gatti's son, Arturo Jr., for the first time in more than two years this past weekend.

The visit was organized after Rodrigues told the court last week that Ida Gatti, Arturo's mother, could see the boy whenever she wanted.
