Legal Question in Family Law in Connecticut

Upon divorce, joint tenants in the real estate (you and your ex-husband) becomes tenants in common, meaning that if either of you die, your share of the real estate is passed to your heirs, not each other. However, the decree should be recorded on the land records to preserve your heir's rights. It's best if you see an attorney to make sure everything is in order.

So, that being said, your children could own the property with your ex-husband. If they agree with your ex-husband and do not want your fiance in the house, he would have to move out.
