Cash. That's what it boils down to for Oksana Grigorieva in her ongoing crusade against Mel Gibson, which is ostensibly about custody of their daughter, Lucia.
The real fight between Oksana and Mel most likely stems from a legal document created before Lucia was even born one year ago, according to a TMZ report.
The Icon Trust, created by Mel and wife Robyn Gibson to provide for their seven children, defines the children as ones born from Mel Gibson or Robyn Gibson.
GETTING HERS: Oksana's apparently determined to.
When the trust was drafted, no one thought Mel or Robyn, married for nearly three decades, would have a child outside the marriage. Enter Oksana Grigorieva.
Sources connected with Mel and Robyn say everyone wants Lucia to be taken care of, but adding her as a beneficiary in Mel's trust creates complex tax issues.
For whatever reason, Mel didn't want that to happen. So when he and Oksana broke up and struck a settlement deal in May, this was one of the key points.
