If you were providing health insurance for your spouse before you filed for divorce, the answer is “Yes”. In California, any existing health insurance policies must be maintained until a divorce is finalized. When a divorce is filed, a Summons is issued by the Court which specifically states, in part:

“Starting immediately, you and your spouse or domestic partner are restrained from: cashing, borrowing against, canceling, transferring, disposing of, or changing the beneficiaries of any insurance or other coverage, including life, health, automobile, and disability, held for the benefit of the parties and their minor children.”

A party in the middle of divorce may face serious penalties if they remove their spouse from an existing plan. If there is a cost to maintaining the plan, you could consider filing a motion with the court to address that issue until the divorce is finalized.
