Actor-director Mel Gibson will pay the mother of his toddler daughter $750,000 under a settlement disclosed Wednesday that allows her and the child to remain in their Sherman Oaks mansion.

Oksana Grigorieva will be paid in three installments, the final one coming in January 2016 under a deal that will allow her to stay in the home she shares with their daughter, Lucia.

When Lucia reaches 18 years old, the home must be sold and the proceeds placed in a trust for her, said L.A. County Superior Court Judge Peter D. Lichtman.

Gibson and Grigorieva, a Russian musician, will have joint legal custody.

Last summer, Grigorieva agreed to a settlement worth $16 million but later said she consented under duress.

That deal came after lawyers for Grigorieva demanded $20 million and revealed she had secretly recorded vulgar, racist rants made by Gibson during their time together.

The episode turned into one of Hollywood's ugliest splits with the tapes being posted online, derailing Gibson's comeback attempt after a 2006 drunk driving arrest during which he spewed anti-Semitic insults.

An L.A. County Sheriff's Department investigation into claims of extortion against the girlfriend did not result in charges. Gibson pleaded no contest to a misdemeanor battery charge involving Grigorieva.

The new agreement bars Gibson and Grigorieva from writing books about their relationship.

Gibson spoke briefly in court and thanked the judge for bringing the case to a "reasonable conclusion."
