The Pros and Cons of Separation vs. Divorce

The Pros and Cons of Separation vs. Divorce

Legal separation and divorce are two distinct legal processes under Illinois law. A legal separation keeps the marriage intact while spouses live apart under court orders; a divorce legally dissolves the marriage and brings finality.

Each path carries real consequences for support, parenting, property, and benefits. We help Illinois spouses weigh the options and choose the step that fits their situation, whether that is separation, divorce, or staying the course for now.

Key Takeaways:

  • Legal separation and divorce are separate legal processes in Illinois.
  • Simply moving out of your marital home does not automatically make you legally separated (you have to petition for it in “the circuit court of the county in which the petitioner or respondent resides or in which the parties last resided together as husband and wife”.
  • A legal separation does not end your marriage, but spouses may become subject to one or more court orders due to their decision to separate.
  • Illinois courts can issue binding orders on child custody, child support, and spousal support during a legal separation.
  • Only a court-entered Judgment of Dissolution of Marriage ends a marriage.
  • Spouses who are legally separated cannot remarry, but those who are divorced can
  • In some situations, staying legally married while living apart allows one spouse to retain critical benefits like health insurance or pension eligibility (which is one of several factors that may inform your marital decisions)

The primary difference between legal separation and divorce comes down to one fundamental point: whether your marriage ends.

Legal separation does not end your marriage. It is a court-recognized status that allows spouses to live apart under enforceable orders, while remaining legally married. To become legally separated in Illinois, two things must happen:

  1. You must move to a different residence. Half measures, like sleeping in separate bedrooms, do not qualify. Living in different buildings on the same property (think: a detached building) could potentially satisfy the requirements for legal separation.
  2. You must file for legal separation with the appropriate circuit court in Illinois: Barrington residents file with either the Cook County Circuit Court or the Lake County Circuit Court, for example. The law says that “the circuit court of the county in which the petitioner or respondent resides or in which the parties last resided together as husband and wife” may hear a petition for legal separation. You can find your designated local court through the Illinois Courts website.

Once the court accepts the filing, a judge can issue orders on parenting time, child support, and spousal support. In contrast, those protections do not exist without a formal filing.

A Divorce Ends the Marriage. What Else Does It Do?

If you want to end your marriage in Illinois, you get divorced. Once a court enters a Judgment of Dissolution of Marriage under the Illinois Marriage and Dissolution of Marriage Act, the marriage is legally over.

That judgment will also address issues frequently associated with divorce, such as:

  • Division of marital assets and debts
  • Allocation of child custody and parenting time
  • Child support payment schedules and amounts
  • Alimony and spousal support

Once the court enters that judgment, both spouses are legally free to remarry. They can even remarry one another, if they choose to.

Yes. Legal separation is not required before filing for divorce in Illinois. Many couples skip the separation step, feeling strongly that the marriage cannot be salvaged.

Rather than enduring two separate legal proceedings (for separation and then divorce), couples who know it’s over can just get divorced.

The difference between legal separation and divorce is not just a legal distinction. There are also practical considerations. For some couples, separation is the right choice for specific financial, personal, professional, and even religious reasons.

Reason #1: Spouses Need a Break, But Aren’t Ready to End the Marriage

For couples not yet ready to end the marriage, legal separation offers a structured middle ground. It is a break with defined conditions, and living apart under a court order can give both spouses a realistic look at:

  • Separate households and finances where each spouse manages their own residence and expenses independently
  • Court-ordered custody arrangements, through which parenting time is clearly defined and governed
  • Whether divorce, reconciliation, or indefinite separation makes sense, as legal separation allows spouses to keep options open in a way that a divorce does not 

Illinoisans who aren’t ready to accept the finality of divorce may view legal separation as a logical, less permanent alternative.

Reason #2: Benefits Are at Stake

In some cases, one spouse depends on the other’s employer health insurance or has not yet qualified for their pension or Social Security benefits. The Social Security Administration outlines how marital status affects spousal benefit eligibility.

Even if couples might otherwise get divorced, preserving access to a spouse’s benefits can be an ample reason to legally separate, rather than dissolve a marriage.

Reason #3: Religious or Cultural Beliefs Prohibit Divorce

For some spouses, faith or cultural values make divorce a problematic or even prohibited step. Legal separation may be an alternative that affords many of the benefits of divorce without technically dissolving a marriage.

Reason #4: Protecting the Kids 

Legal separation orders can provide children with a sense of structure while their parents work through a difficult transition and figure out the next steps. Children may benefit from the predictability afforded by:

  • Parenting time schedules
  • A parental decision-making framework (dictated through custody rights)
  • Legally enforced support obligations (affording some degree of financial stability for children)

These clear, court-ordered ground rules can reduce conflict and uncertainty during a difficult time in children’s lives.

When Might Divorce Be the Right Choice for Spouses in Illinois?

For many couples, legal separation is an unnecessary step. Separating would simply delay the inevitable for couples whose differences are irreconcilable. It can, therefore, be a problem for them that legal separation means:

  • You remain legally married, meaning you cannot remarry, and financial ties remain in place in ways that a divorce would resolve permanently.
  • Separation lacks finality because issues such as property division are not permanently resolved during a separation but are addressed through a Judgment of Dissolution of Marriage.

In contrast, couples who are certain the marriage is over often find that divorce addresses all of these issues in a single proceeding.

For couples who are certain the marriage is over, divorce is often the more cost-effective path. The reason is straightforward: legal separation requires its own filings, attorney fees, and court orders. If you separate only to eventually participate in divorce proceedings, that may mean twice the legal costs.

How Should Illinoisans Approach the Decision Between Separation and Divorce?

If you’ve thought about legal separation, divorce, or another resolution to marital issues,  consider the following before making a decision:

  • Assess your financial picture first: Determine whether any benefits (such as health insurance, pension eligibility, or Social Security) depend on you remaining married. Many clients find it helpful to consult a financial advisor from our team alongside their attorney before making this call. Financial considerations, such as spousal support and child support, are also worth considering before proceeding with either separation or divorce.
  • Think about what your children need: Court-ordered parenting time during a separation can provide near-immediate structure, and that can be a plus. Consider whether that stability is a priority in your marital decision-making.
  • Pinpoint your goals: If you want finality, closure, and the right to remarry, a legal separation cannot deliver those outcomes. If you need time to think and evaluate or have benefit-related reasons to stay married, separation may serve you better in the short term.
  • Know the legal requirements for a legal separation: Remember that in Illinois, physically leaving the home does not qualify as a legal separation. Without a court filing, you have no enforceable orders on custody, support, or property.
  • Talk to an Illinois divorce attorney from our team: The choice between separation, divorce, or status quo has long-term consequences for spouses, children, property, benefits, and parental rights. Getting legal guidance before you file constitutes fairly basic due diligence, given the stakes of such decisions.

Q: Do my spouse and I have to live in separate homes to be legally separated in Illinois?

A: Living apart generally supports a legal separation, but the status itself comes from the court order, not the move. The step that creates it is filing a petition for legal separation in the proper circuit court. Until a judge enters orders, living separately gives you no enforceable terms on support, parenting time, or property.

A: A legal separation can continue indefinitely in Illinois. There is no automatic expiration date, and the separation remains in effect until one or both spouses file for divorce or the court modifies the existing orders.

Q: Can I date while legally separated in Illinois?

A: You can date while legally separated, but you cannot marry another person until your divorce is finalized. Because you are still legally married during a separation, entering a new marriage would be considered bigamy under Illinois law.

A: Usually not, if divorce is the likely endpoint. A legal separation has its own filing fees, court orders, and attorney time, and a later divorce repeats much of that work. Spouses who are confident that the marriage is over often spend less by filing for divorce once rather than paying for two separate proceedings.

Separation vs. Divorce Questions Answered by Our Illinois-Based Attorneys

Many spouses in Illinois considering separation or divorce ask us:

Yes. Unlike divorce, a legal separation in Illinois requires both spouses to agree. If your spouse objects and wants a divorce instead, the court can treat the petition as a divorce filing.

What happens to health insurance coverage during a divorce in Illinois?

When a divorce is finalized, a spouse covered under the other’s employer health plan typically loses that coverage. In contrast, legal separation allows coverage to continue because the marriage remains intact. If health insurance is a deciding factor in your marital decisions, you should review your plan’s terms with one of our attorneys before filing.

Not necessarily. Illinois legal separation orders may not be automatically recognized or enforceable in another state. If you or your spouse plans to relocate, that potential interstate complication is worth discussing with a family law attorney on our team.
