Yes, you can reopen your case if your ex lied about his property. In every divorce, both spouses are required to make a complete financial disclosure.
If your spouse lied, that is a very serious infraction that most judges would highly disapprove of. You can reopen the property division aspect of your case.
In order to do so, it would be best to hire an attorney. It’s highly possible that the judge would order your ex to pay your attorney’s fees, since his malfeasance necessitated the case being reopened.
In other cases, if your divorce is final and you don’t like the outcome, you must appeal. You can appeal any ruling, but strict time limitations apply, so it’s best to make a decision about the appeal quickly.
In order to appeal, there are complicated, technical procedures that must be followed. In order to successfully appeal, you must show there was some mistake of the law or procedure that was not filed, or there is some information that was not considered.
Just because you did not like the outcome of the divorce does not mean that you can successfully appeal the judge’s ruling.
Most people are excited to put a divorce behind them, and do not relish the thought of opening it again. If your ex lied about his property during the divorce, in most cases it will be worth the effort of reopening the case in order to get property to which you are entitled.
