My father left us when we were young, leaving my mother with 9 young children to bring up on her own, my father was never divorced from my mother but we have now found out that he remarried whilst still married to my mother. He died before his second wife and she has also passed away. As their marriage was illegal what can be done. Could I have a claim, could I annul his marriage I know that there was a lot of people who knew aboutr this

What are you actually trying to get out of this? And what country or countries are we talking about. Bigamy or Polygamy isn't illegal in all countries.
