My FH was previously married and left his ex in June of 2015 and filed for divorce later that month. By November of 2015 they had gone to court and received temporary orders for everything (split of property, custody of their child, etc). His ex and her attorney were responsible for drawing up the final divorce decree. Two years later and less than 5 months from our wedding and we just found out his divorce was never finalized...and his ex knew the whole time and kept it that way. FH is in the wrong for not checking in with his attorney but he received a draft of the divorce decree and assumed it was done...all that was missing was his exs signature and then she had to go before the judge with FHs attorney once she signed.
ETA: the issue is that the ex, or I guess current wife, has made it clear she plans to make it difficult. She has even taken to social media sayin. "Ps we are still married so good luck with the wedding" with a big smiley emoji
