Lockyer, 71, cited "irreconcilable differences" in his filing in Alameda County Superior Court, said spokesman Tom Dresslar. The veteran Democratic politician has been married to Nadia Lockyer since April 2003, and they have a 9-year-old son.
Their troubles became known in February when she said she was injured in a violent assault at the hands of her former boyfriend, Stephen Chikhani, a methamphetamine user she met in an addiction treatment program. The California Department of Justice, which took over the assault inquiry from Alameda County, declined to pursue charges against Chikhani.
Nadia Lockyer, 41, resigned in April as Alameda County supervisor, a post she won in 2010 thanks in part to $1.5 million in contributions from her husband's war chest. She said in her resignation statement that she could no longer balance her duties as a mother and supervisor while recovering from addiction and dealing with the "aftermath of interpersonal violence," a reference to the Chikhani incident.
"(Bill) Lockyer wants two things," Dresslar said. "Above all, he wants the matter resolved in a way that serves the best interests of his son. Two, he wants it handled as privately and amicably as possible."
