The Gibsons' $900-Million Divorce

Mel Gibson and wife Robyn met after the filming of "Mad Max" in the '70s. The two have been married for 28 years, have a $900 million fortune... and no pre-nuptial agreement.

TV judge Jeanine Pirro tells "Extra," "She was a dental assistant and he was an unknown actor when they married. There is no pre-nup."

Pirro is a former prosecutor and she says with California's standard of 50/50 divorce settlements, the stakes are huge on both sides. Pirro says, "California law is very clear. 50/50 anything maintained or attained during the marriage."

The list of assets is staggering! They share a $26-million Costa Rican pad, a $15-million island in Fiji, a $42-million church Mel is building in Malibu and the $12-million Malibu home they purchased from David Duchovny and Tea Leoni. The Gibsons also own second home in Malibu that they bought for $1.9 million and a 9-acre piece of property in L.A. valued at $3.5 million.

Pirro believes Robyn will get exactly 50% of the couple's fortune, "She'll probably get $450 million." If Robyn is awarded half, it would make previous record settlements in Hollywood look like chump change.

Basketball megastar Michael Jordan's ex-wife Juanita received $168 million and Neil Diamond's ex, Marcia, was awarded $150 million. Steven Spielberg's first wife, actress Amy Irving, walked with $100 million.
