Mediation is a great way to resolve issues in your divorce without having to litigate them in court. Many Illinois couples utilize mediation because it offers efficiency, cost savings, and greater control over outcomes than traditional litigation. If you are considering divorce in Illinois, you may be considering mediation, and you may also be wondering whether a mediated divorce agreement is actually enforceable under Illinois law.

The answer is, mostly, yes: mediated divorce agreements can be enforceable in Illinois, but it has to be reviewed by a judge and incorporated into the final Judgment of Dissolution of Marriage first.

Understanding Mediated Divorce Agreements

Divorce mediation is a voluntary process in which spouses work with a neutral third-party mediator to resolve issues arising from their divorce, like who is going to keep the house or how they will divide their retirement assets. Parties can mediate issues around the kids, as well

The mediator does not act as a judge and does not take sides. Instead, the mediator facilitates discussion and helps the parties reach mutually acceptable resolutions between themselves.

In Illinois divorce mediation, parties often address:

Division of marital property and debts
Spousal maintenance
Allocation of parental responsibilities
Parenting time
Child support

At the end of the mediation process, the parties may have reached a full settlement or a partial one. The mediator prepares a document called a memorandum of understanding (MOU) summarizing the agreed terms. An MOU is not the same thing as a court order, however. It is not even necessarily a binding contract.

Is a Mediated Divorce Agreement Enforceable?

The enforceability of mediated divorce agreements is primarily governed by Section 502 of the IMDMA (750 ILCS 5/502), which expressly authorizes parties to resolve issues in dissolution proceedings by agreement.

Under Section 502, parties may enter into written settlement agreements. Agreements addressing property division and maintenance will be incorporated into the final divorce decree and become legally binding unless the court finds them to be unconscionable. Agreements affecting children are subject to the court’s independent determination of the child’s best interests. In other words, the court will determine whether the terms of the parties’ agreement concerning parenting time, child support, or the allocation of parental responsibilities is in the best interest of the children before incorporating them into a judgment.

Settlement agreements become enforceable only after being approved by the court and incorporated into the Judgment for Dissolution of Marriage (or another final order). In other words, mediation produces an agreement, but court approval transforms the agreement into an enforceable court order.

What Makes an Agreement Unconscionable?

Illinois courts do not simply “rubber stamp” mediated divorce agreements. Instead, the IMDMA requires the court to review the agreement and assess its fairness.

Under 750 ILCS 5/502(b), a court must honor an agreement between parties concerning property division or maintenance unless the court finds the agreement is unconscionable. While Illinois courts strongly favor settlements, they retain authority to reject agreements that are fundamentally unfair.

Factors courts may consider include:

Disparity in bargaining power
Inadequate financial disclosure
Extreme imbalance in the division of assets

Heightened Scrutiny for Child-Related Issues

Agreements involving children are treated differently. The court has an independent obligation to ensure that provisions regarding parental responsibilities, parenting time, and child support serve the child’s best interests.

Even if both parents agree:

A court may reject parenting arrangements that are not in the child’s best interests.
Child support provisions must comply with statutory guidelines unless the parties can justify agreeing to a higher or lower amount.
Parents cannot permanently waive child support or otherwise bargain away a child’s rights.

The Uniform Mediation Act (UMA)

Illinois has adopted the Uniform Mediation Act (710 ILCS 35/1 et seq.), which strongly protects the confidentiality of mediation communications. Statements made during mediation are generally inadmissible in court. For that reason, oral agreements reached during mediation are difficult to enforce. There are some exceptions to confidentiality in mediation, and written agreements signed by the parties may fall within those exceptions, but those written agreements will be virtually unenforceable if they are not incorporated into a court order.

To recap, once a mediated marital settlement agreement is:

Reduced to writing,
Signed by both parties, and
Approved and incorporated into the Judgment for Dissolution of Marriage,

it becomes fully enforceable as a court order.

At that point, the agreement has the same legal force as a judgment entered after trial. A party who violates the agreement may be subject to enforcement actions, like being held in contempt of court, being fined, or having their wages garnished.

Want Your Mediated Agreement to Hold Up in Court?

You just spent hours mediating your divorce in order to avoid costly litigation. Do not throw away all of your hard work! To maximize enforceability of your mediated agreement under Illinois law, do the following:

Ensure that all parties to the mediation have provided a full and accurate financial disclosure during mediation.
Reduce all terms of the agreement to a detailed written marital settlement agreement.
Have each party review the agreement with independent counsel.
Include clear language in the Judgment of Dissolution of Marriage that the settlement agreement is to be incorporated therein.

Modification and Enforcement After a Judgment is Entered

Once incorporated into a judgment, property division provisions are generally final and non-modifiable. Maintenance, child support, and parenting provisions may be modified later, so long as a party can make a showing of a substantial change in circumstances. If a party doesn’t follow the terms of the agreement, the other party can seek to have the Court enforce the order.

This is why your choice of mediator matters; careful drafting of an MOU at the mediation stage is important because some terms, once approved, are permanent.
