I am confused. Something must be missing.
FL cannot simple "not recognize" a KY judgment. They must. It is in the Constitution. Your ex could have set it aside, but to "not recognize" it makes no sense.
Your ex should have filed a motion to set it aside in KY, or filed a Custody Action (not a divorce) in FL, but for FL to not recognize a valid KY order does not make sense. Furthermore, if I understand this right, there was NO child born during the marriage, because your child was actually born prior to the marriage.
The Florida Divorce should have been entered "nunc pro tunc," which means its entered prior to your second marriage, OR the Florida divorce should have dealt with only child support
, custody, and property, but NOT status. In other words, the KY divorce stands as far as the actual severing of the marriage.
IMHO Jane is either married to XXXXX XXXXX or John Doe, and should not marry XXXXX XXXXX.
BTW, did you have an attorney in FL? I'm assuming you didn't. And I don't think it is relevant that XXXXX XXXXX had or didn't have notice. There is a valid KY judgment that he needs to deal with.
Wow... what a mess. I hate to say it, but you really need a Family Law
attorney in Florida to straighten this out.
