CNN -- A judge has tentatively ruled a lawsuit accusing a concert promoter of contributing to Michael Jackson's death can go to trial.

The wrongful death lawsuit was filed by Jackson's three children and his mother, against his concert promoter A-E-G Live.

The judge has ordered Doctor Conrad Murray to meet with Jackson lawyers next month for a deposition.

Lawyers for Jackson's children contends Murray was hired and supervised by A-E-G Live executives, and that they were negligent in hiring Murray.

Murray was convicted of involuntary manslaughter in Jackson's 2009 death.

The wrongful death trial is set for April.
