Mel Gibson's former partner OKSANA GRIGORIEVA signed an agreement not to chase the actor/director for money if they split - just a month before the pair's alleged violent bust-up in January (10).
The couple ended their relationship in April (10) and the break-up turned nasty when the Russian singer accused her former partner of beating her during a violent argument at the beginning of the year (10). Taped arguments between the pair subsequently surfaced online and the lurid content hit headlines across the world.
It was recently reported that Gibson agreed to hand over $1 million (£666,667) for the return of "all evidence" which would be "destroyed in a manner agreed upon by both parties."
The "evidence" was purportedly the now infamous taped rants, as well as other emails, texts and photographs.
The May (10) document, which was obtained by TMZ.com, also set out a "50-50" custody share of the former couple's daughter, Lucia, and detailed a financial plan for the youngster's future, as well as payments for Grigorieva. The Russian singer later pulled out of the agreement.
But another document found by the website reportedly shows that Grigorieva had already signed papers stating she had no right to claim any of the Lethal Weapon star's vast fortune, which was described as "in excess of $150 million", in December 2009, just weeks before their alleged fight.
According to TMZ.com, the papers stated, "Neither party has promised the other to assist in funding any support for each other or the other party's children from other relationships."
At the time, Gibson agreed his partner could remain in his California home, but that he could evict her with 12 months written notice.
