A divorce decree could be invalid if a judge's decisions were based on incorrect information or if the judge made errors affecting the outcome. If one party concealed assets or debts from the other, that could be grounds for appeal or modification.
There is one item that can be modifiable but is not always: maintenance (also known as spousal support or alimony). Your judgment can include one of two types of maintenance: Non-Modifiable Term Maintenance – This is maintenance for a set period of a time (for example: for 18 months following the divorce).
Yes, you can amend a marital settlement, with both parties agreeing.
You can absolutely change it before filing. You can even change it after filing if the other side has not responded and if you need to change it after that, you can ask the Court's permission.
Parenting time and child support, which are also part of a final decree, may also be modifiable. At the time a divorce is finalized by court order, so are visitation and custody agreements.
Amending Your Divorce Decree via a Change of Circumstances If one party undergoes a material or other substantial change in their life situation, they may be able to seek a modification of the original divorce decree. The party must have a significant change in these cases.
In order to change your divorce decree, parenting plan, or other court orders from your divorce, you must file a Petition for Modification. To initiate the process, you must file a petition with the circuit court in the county where the original order was entered.
The only way to reopen your case is if there is some noncompliance with the original Judgment for Dissolution. You need to consult in person with an experienced family law practitioner.
