Legal Question in Family Law in Washington

It is difficult to know the answer to your question for sure, because I would need to read the file to answer it accurately. However, my suspicion is that his divorce with his ex-wife is valid. The fact that he lied does not go to the issue of whether or not the court had jurisdiction and thus the ability to dissolve his marriage to his last wife. However, his ex-wife may be able to reopen the divorce to ask for child support or some other relief if she was denied this as a result of him lying about not having a child.

Therefore, I do not think that your marriage was void from the start. I think you simply have to start your own dissolution of marriage proceedings and obtain a divorce through normal channels.

Best of luck,
