Kelsey Grammer has stepped up his legal battle with ex-wife Camille - he wants to go to trial to allow a judge to decide who should gain full custody of their children, according to a report.
The actor parted ways with reality TV star Camille last summer and he has since wed Kayte Walsh.
The ex-couple was expected to seek joint custody of son Jude, six, and daughter Mason, nine, but last month Grammer requested to be recognized as their primary guardian.
Camille has since challenged Grammer's claim, filing her own legal papers for sole custody.
The actor/producer has now submitted further documents revealing the former couple and their two kids are being analysed by a child custody expert - and he wants the custody battle to head to trial when the evaluation is completed, according to TMZ.com.
