The Russian singer attended a closed hearing at a Los Angeles court room yesterday (18.08.10) to continue discussions about the custody of the couple's nine-month-old child, where it is believed her lawyer's bid for her to be the tot's sole carer.
According to a summary posted outside the courtroom, a motion about seizing Lucia's passport was to be debated, a move that would mean neither parent could take the child out of the country.
Mel did not attend the hearing, which also looked at child support and attorney fees.
Oksana, 39, split from the 'Braveheart' actor earlier this year.
Since their bitter split, tapes have been leaked which apparently feature the 54-year-old star assaulting Oksana and launching into several hate-filled and expletive-riddled rants.
The actor is now being investigated by the Los Angeles County Department of Children and Family Services over allegations he assaulted the singer while she was holding Lucia.
He is also being investigated by the Los Angeles County Sheriff's Department over domestic violence claims.
