Life & Style has exclusively learned that Josh Duggar will be questioned under oath about the cheating scandal that rocked his family in 2015.

It was revealed that the father-of-four, who has been married to wife Anna since 2008, had become a member on Ashley Madison, a dating service that caters to individuals looking to have an affair. But according to a lawsuit brought against the 29-year-old, he used the image of LA DJ Matthew McCarthy on his profile without permission.

In Touch reported last month that Josh had been served legal papers in the lawsuit, and the plaintiff’s lawyer, Michelle Iarusso, tells Life & Style that she will be asking questions about his activity on both Ashley Madison and OKCupid “to know the extent of the fraudulent conduct.”

“We need to know if there are people out there who think that they have been in touch with our client because Josh was pretending to be him,” Michelle explains. The fact that he admitted to molesting five underage girls, four of whom were his siblings, in the early 2000s also affects the case.

“That makes my client’s forced association with Duggar all the more painful for him,” Michelle shares. “He certainly would rather not have been associated with a child molester. And prospective employers didn’t like it, either.”

According to documents obtained by In Touch, Matthew argues that Josh’s use of his photo resulted in loss of work, harassment from the public, and prolonged pain and embarrassment.

Happy birthday, Josh. We love you, your amazing wife and sweet children. We pray that you diligently follow and serve…

News of the lawsuit came shortly after the oldest Duggar announced that his wife is pregnant with their fifth child. “For nearly the last two years, we have quietly worked to save our marriage, focus on our children, and rebuild our lives together as a family,” they wrote in a joint statement. “We are delighted to share with you that we are expecting a new baby boy later this year.”
