Legal Separation vs. Divorce in Connecticut: Key Differences
Connecticut Offers Both Options
Connecticut is one of the states that recognizes legal separation as a formal court action, separate from divorce. Under C.G.S. § 46b-40, you can file for either a "dissolution of marriage" (divorce) or a "legal separation" through the Superior Court. Both follow nearly identical procedures, use the same forms, and go through the same court system.
The critical difference: a legal separation does not end your marriage. You remain legally married, which affects your ability to remarry, your tax filing status, and certain benefits like health insurance and Social Security.
How the Processes Compare
The filing process for legal separation mirrors divorce almost exactly:
| Element | Legal Separation | Divorce |
|---|---|---|
| Complaint form | JD-FM-159 (check "legal separation") | JD-FM-159 (check "dissolution") |
| Service of process | Same — marshal or waiver | Same |
| Filing fee | $360 | $360 |
| Financial Affidavits | Required — JD-FM-6 | Required — JD-FM-6 |
| Automatic Court Orders | Yes — JD-FM-158 | Yes — JD-FM-158 |
| 90-day waiting period | Yes | Yes |
| Property division | Court divides equitably | Court divides equitably |
| Alimony | Court can order | Court can order |
| Child custody/support | Court can order | Court can order |
| Marriage status | Still legally married | Marriage terminated |
Both actions address the same practical issues — property, debt, support, and children. The court has the same authority to divide assets and order support in either proceeding.
Why Some People Choose Legal Separation
Health insurance. This is the most common reason. If one spouse is covered under the other's employer health plan, divorce typically ends that coverage. Legal separation keeps the marriage intact, and many employer plans continue to cover a legally separated spouse. Check your specific plan — some treat legal separation the same as divorce.
Religious or personal beliefs. Some couples object to divorce on religious grounds but need court orders addressing finances, custody, or living arrangements. Legal separation provides court-enforced terms without dissolving the marriage.
Social Security benefits. If you have been married for at least 10 years, you may be eligible for Social Security spousal or survivor benefits based on your spouse's earnings record. Legal separation keeps the marriage alive, preserving this eligibility. If you are close to the 10-year mark, legal separation can be a strategic bridge.
Hope for reconciliation. Some couples use legal separation as a structured pause — getting court-ordered financial boundaries and custody arrangements while leaving the door open for reconciliation.
Immigration considerations. In some immigration contexts, maintaining the legal marriage is important for pending visa petitions or residency applications. Legal separation provides court protection without triggering the immigration consequences of divorce.

Converting Between Separation and Divorce
Connecticut allows either spouse to convert a legal separation into a divorce — or vice versa — under certain conditions.
If you have a legal separation decree and later want to divorce, you can file a motion to convert it to a dissolution. You do not need to start the entire process over, but the court will revisit the terms of your agreement since circumstances may have changed.
Similarly, if you filed for divorce but decide you prefer legal separation, you can amend your complaint before the final decree is entered.
When Divorce Is the Clearer Choice
For most people, divorce is the better option if the marriage is truly over. Legal separation creates an indefinite legal limbo — you have all the obligations of a court-ordered settlement but cannot remarry, and you remain legally tied to your spouse for tax, debt, and estate purposes.
If health insurance is the only reason you are considering legal separation, compare the cost of your spouse obtaining independent coverage (through the ACA marketplace or COBRA) against the ongoing legal and practical complications of staying married. In many cases, the math favors a clean divorce.
Filing Either Action in Connecticut
Whether you choose legal separation or divorce, the filing steps are the same: prepare the Summons (JD-FM-3), Complaint (JD-FM-159), and Automatic Court Orders (JD-FM-158); serve your spouse; file with the clerk; exchange Financial Affidavits; attend the Resolution Plan Date; and submit your agreement for court approval.
