The Ultimate Illinois Divorce Checklist

Starting a divorce proceeding in Illinois requires strict compliance with legal regulations and adherence to all deadlines. To make the process smoother, we created this checklist of essential tasks and documents you need to know about before divorce proceedings start.

What things should you consider when preparing for divorce? 

It’s helpful to know whether you and your spouse are on the same page about various issues that will inevitably come up in your divorce process. For example, you will want to know whether you will be filing a contested divorce or an uncontested divorce. If you can, find out how you and your spouse align on the following issues.

Asset allocation

Do you expect to stay in the house or move? Are you keeping your car or selling it to split the proceeds with your spouse? What will you do with any vacation properties, boats, investment portfolios, or high-end art pieces the two of you own?

Find out the degree to which you and your spouse agree on your answers to these questions. In divorce, everything you accumulate during marriage must be divided. 

Debt responsibility 

Debts that built up during the marriage will need to be paid as soon as possible. That could mean selling an item attached to a loan, such as a car or house. It could mean closing the credit card account and figuring out who is going to pay any outstanding balances.


If one spouse supported the other spouse financially or made considerably more money than the other, it may be appropriate for them to pay spousal support (alimony). 

The amount of those payments, and how long they will last, will need to be discussed. For example, you may decide that when a certain income threshold is crossed or a certain number of years have passed, spousal support payments will stop.

Child custody and support

The goal of any child custody and support arrangement should be to prioritize the child’s best interests during the divorce and beyond. To that end, talk about what your parenting plan will look like. This includes details about custody and visitation arrangements as well as child support amounts, who will cover the cost of extracurricular activities, who will be responsible for medical care and decisions, and other details. 

Note that both parents are legally obliged to support their children financially after divorce. Regardless of income, it is a parent’s job to make sure each child’s needs are met.

Mediation vs. legal assistance

Mediation is by far the most efficient and cost-effective choice if you find that you and your spouse need help negotiating different aspects of your divorce settlement. Lawyers often require a multi-thousand dollar retainer to get started, and they generally advise courses of action that require you to continue paying for their services. 

You can save a lot of money by working with a mediator instead. Mediators usually charge by the hour at a much lower rate than a divorce attorney. Your mediator will work to help you resolve your issues so everyone’s rights are protected and children are prioritized. 

By working with a mediator, you can save the money, time, and stress involved in going to court.

Type of divorce

As long as you and your spouse can come to an agreement on the major points of your divorce, you can file an uncontested divorce in Illinois. An uncontested divorce is usually preferred over a contested one because it costs so much less.

Though you may need to meet with a mediator or legal professional to reach the “uncontested” status, it will still cost less than working with a trial lawyer who charges a hefty retainer fee.

If you find that you cannot agree with your spouse on the details of your divorce – even with mediation or legal help – you will need to file for a contested divorce. If you go this route, prepare for a considerable amount of paperwork, time investment, and cost.

Why is an Illinois divorce checklist so important to have?

Personal information needed for divorce 

Be prepared to provide this information:

  • Your full name, address, and contact information
  • Your Social Security number and date of birth
  • Your personal identification documents (driver’s license or passport)
  • Your employment details and income documentation

  • Your spouse's full name, address, and contact details
  • Your spouse's Social Security number and date of birth

Marital property and divorce in Illinois 

Illinois defines marital property as assets and debts acquired during the course of marriage. According to Illinois law, marital property must be divided during divorce proceedings in an equitable distribution. It’s important to note that “equitable distribution” does not necessarily translate into a 50/50 split.

Marital homes and real properties

Options include selling the property and splitting its proceeds or having one partner keep the property while buying out the other’s share of the investment.

Financial assets 

This includes bank accounts, investments, and retirement accounts. An equitable division may involve transferring a portion of assets or altering payments of spousal support.

Personal property 

This may include things like furniture and vehicles. Spouses can work out an agreement to sell shared property and split the profits, or they may choose who gets to keep each item.


This may include loans and credit card balances These accounts are typically closed. The responsibility to pay off the remaining balances is divided between spouses based on their respective financial situations.

Business interests and investments

If there is a family business in the mix, unless spouses intend to continue co-ownership, it will either need to be sold, or one party will need to buy out the other. Options involving a sale require a valuation of the business and its assets.

Start the process of separating your lives

Beginning to rebuild your life independent of your marriage is an important part of the divorce process emotionally as well as financially. Take these steps:

Establish individual financial accounts

Achieve financial independence and untangle joint finances. Open a personal bank account and credit card in your name. Do not use any accounts that were used during your marriage.

Organize financial records

Gain clarity on your financial situation. Compile bank statements, tax returns, and investment records. You need to manage expenses and plan for your post-divorce finances. Create a detailed budget that covers living costs, child-related expenses, and savings goals.

Review and update legal documents

Make sure your will, trust, and power of attorney reflect your current wishes. Update beneficiaries and decision-makers in estate planning documents. Manage all paperwork and deadlines efficiently, and implement a system to track documents, court dates, and essential communications.

Establish a parenting plan

Establish cooperative co-parenting for your children's benefit. Keep the lines of communication open regarding parenting schedules and decisions, and maintain a routine that's both stable and consistent for your children.

Seek emotional support

Divorce can be a very trying process mentally and emotionally. Doing the emotional work associated with divorce requires you to take proactive steps. Seek counseling or support groups for assistance, and make time for self-care. Acknowledge the stress and emotional work so you can process it and move forward. 

Special considerations for divorce

Some divorces have unique considerations based on personal factors. 

For example, Illinois military divorce proceedings are governed by the Soldiers and Sailors Civil Relief Act (SSCRA). This act permits postponing divorce proceedings until active duty service ends plus 60 days post-service. This protects active-duty service members and gives them enough time to prepare a response.

For same-sex couples, the same rules apply. However, if one person adopted a child, there may be issues with child custody if they came into the picture later or if they do not have legal custody of the child.
