Los Angeles, California - Amber Heard is facing a legal battle on a new front, this time with her insurance company.

New York Marine and General Insurance Co. filed a lawsuit against the Aquaman actor Friday in federal court, seeking a ruling about whether it has to pay Heard after her unsuccessful defense of a defamation lawsuit brought by her ex-husband, Johnny Depp. The insurance company said in the lawsuit that it doesn’t believe it has an ongoing obligation to defend Heard.

A spokesperson for Heard was not immediately available for comment Friday.

"An actual controversy has arisen and now exists between Plaintiff, on the one hand, and Heard, on the other hand, with regard to the duties and obligations owed between Plaintiff and Heard under the Policy with respect to indemnity" for her actions in the Depp case, the insurance company said in its filing.

The complaint lodged in US District Court in California is the latest potential legal challenge for Heard. It comes a little more than a month after the verdict in the drawn-out, highly publicized trial before a jury in Virginia to decide the merits of Depp’s claim that Heard had defamed him, and Heard’s countersuit.

The trial involved weeks of contentious testimony, including Heard’s graphic allegations of sexual violence during their marriage. Depp denied Heard’s allegations of domestic abuse.

In 2019, Depp brought a $50 million libel case over his ex-wife’s December 2018 op-ed in the Washington Post, in which Heard described herself as "a public figure representing domestic abuse."

The op-ed did not mention Depp by name, but the Pirates of the Caribbean performer maintained that it was clear that he was the subject of the essay.

Last month, Depp won a more than $10-million judgment against Heard after the six-week trial. Depp won three claims against Heard, while Heard won one of three claims she brought against Depp in her $100-million countersuit.

Now her insurance company says it does not believe it has to pay Heard on the policy, which provided liability protection up to $1 million.

The lawsuit said the insurance company had written a policy for Heard in 2019.

"Plaintiff contends it has no duty to defend Heard based on California Insurance Code 533," the insurance company said in its complaint. The state code provides that "an insurer is not liable for a loss caused by the willful act of the insured," the lawsuit said.

The insurer said it had initially advised Heard it would provide a legal defense, but under California law, it did not have to provide an indemnity for her actions.

"The jury’s factual findings establish that Heard’s liability is caused by the willful act(s) of Heard," New York Marine and General Insurance Co.'s suit said.

Heard plans to appeal the jury’s decision in the defamation case.
