It wouldn’t matter. Just because you get divorced doesn’t allow a spouse to testify against marital privilege.
Incorrectly stated. A spouse is allowed to testify against their spouse. The state is not allowed to force them to do it.
Wrong.
“The spousal testimonial privilege which applies only in criminal cases lasts only as long as the marriage does. Additionally, the privilege belongs to the spouse who is being asked to testify. Once a couple divorces, a former spouse can no longer invoke the privilege to avoid testifying in a criminal case, and the other spouse cannot assert the privilege to prevent that testimony from being admitted into evidence on the basis of the privilege.”
