Prominent Fort Worth attorney Jeff Kearney will be replaced by Emily Munoz Detoto of Houston.
Kearney filed a motion Thursday asking that he be withdrawn from the case after a Jeffs representative called, asking for his termination.
The court in remote Schleicher County, Texas, where Jeffs is being held without bail, hasn't yet ruled on the motion. Jeffs retained Munoz Detoto, as co-counsel last week.
Jeffs dismissed well-known Austin attorney Gerry Morris in January, mere hours after hiring him.
The head of the Fundamentalist Church of Jesus Christ of Latter-Day Saints goes to trial July 25 on charges of aggravated sexual assault of a child.
He faces a separate bigamy trial.
