Both cooperative divorce and collaborative divorce can be helpful, but they are two different things.

What Is Collaborative Divorce in Illinois?
Collaborative divorce is a very structured process to ending your divorce. You both enter into a contract-based process outlined by the Illinois Collaborative Process Act. Each person gets an attorney who is trained in collaborative divorce. The team might also have neutral professionals such as:
- A financial neutral
- A child specialist
- A divorce coach or communication facilitator
Spouses agree to exchange information and work together to find a settlement. If the process ultimately fails, both of the attorneys have to withdraw. The parties then hire new counsel and proceed to litigation in court.
What Is Cooperative Divorce in Illinois?
Cooperative divorce is less formal. No specific law governs the process and you don’t need a participation agreement. Both spouse agree to negotiate with one another before litigation to try to avoid court as much as possible.
Key features of cooperative divorce include:
- Attorneys don’t have to leave the case if negotiations fail.
- The process can more informally use mediation and negotiation.
- Spouses maintain more flexibility in how the case progresses.
Key Differences Between Cooperative and Collaborative Divorce in Illinois
Both options focus on negotiating an agreement, rather than a protracted legal battle. But how they get there is very different.
1. Level of Formality
Collaborative divorce is a very structured process. The agreement outlines:
- Expectations of the parties
- Rules for communication
- Confidentiality
- Requirements of attorney withdrawal if the process fails
Cooperative divorce is much less formal. You get to control the negotitations and can keep your attorneys if things don’t work out.
2. Attorney Withdrawal Requirement
This is the most significant difference.
- In collaborative divorce, both attorneys must withdraw if the case moves to litigation. This rule is designed to keep everyone committed to settlement.
- In cooperative divorce, attorneys can continue representing their clients in court if negotiations stall.
3. Use of Neutral Professionals
Collaborative divorce will often use other professionals to help resolve problems. These often focus on financial issues, parenting disputes, or communication problems.
Cooperative divorce may use neutrals, but it is optional. You have control over who else gets involved in the process.
4. Transparency and Information Sharing
Both processes encourage voluntary disclosure, but collaborative divorce requires it. Collaborative divorce uses the agreement to obligate each person to give complete information without having to use formal discovery.
In a cooperative divorce, you have the same idea, but you could still use traditional discovery tools if needed.
5. Court Involvement
Collaborative divorce happens outside of court unless you reach a full agreement. There are no hearings or motions in front of the court.
Cooperative divorce might utilize limited court appearances, especially for temporary orders before you agree.
6. Flexibility vs. Commitment

Collaborative divorce offers a structured, team‑based environment but requires full commitment to settlement. If the process fails, spouses must start over with new attorneys.
Cooperative divorce offers flexibility. Spouses can negotiate, mediate, or litigate as needed without resetting the case.
