The Black Crowes singer, who had agreed on the joint custody of their 12-year-old child after the divorce in 2007, has filed to re-open the agreement, reported E! News.
New documents have surfaced wherein Robinson wants the court to re-evaluate the negotiation with Hudson.
According to the papers, both Hudson and Robinson agreed an evaluator will be assigned from the court to perform a child custody evaluation.
"Thereafter, he/she will issue a written report and make recommendations for developing a parenting plan that addresses legal custody and physical custody, including where Ryder shall reside and visitation rights based on the interest of the child," it read.
