My wife and her ex-husband are both from Brazil and were married there before coming to the US. He moved back to Brazil and she filed for divorce in the United States. She also began divorce proceedings in Brazil. The divorce was finalized in Massachusetts in 2008, but four years later, she still has not finalized the divorce proceedings in Brazil. I was not aware of this when we married.
My question is whether or not she is still legally married to her ex-husband in terms of Massachusetts law? I am trying to determine whether or not I have valid grounds for annulment.
