Connecticut Divorce Laws (2026): Grounds, Residency, and Process

To divorce in Connecticut, at least one spouse must meet the 12-month residency requirement, and the most common ground is irretrievable breakdown of the marriage. No separation period is required for that ground. Cases are heard in the Superior Court.

Grounds for divorce in Connecticut

Connecticut recognizes both no-fault and fault-based divorce. The most widely used no-fault ground is that the marriage has broken down irretrievably, stated in a party's sworn complaint or cross-complaint under CGS 46b-40. The court does not require proof of fault and does not require the spouses to have lived apart before filing.

Connecticut also keeps traditional fault grounds. A spouse may allege adultery, fraudulent contract, willful desertion for one year with total neglect of duty, seven years of absence, habitual intemperance, intolerable cruelty, legal confinement for mental illness, or life imprisonment. Fault grounds are less common in practice, but they remain on the books and a court may consider fault when dividing property or setting alimony.

There is a third no-fault route: living apart for incompatibility for 18 or more continuous months before the complaint is filed. This path is rarely used because it requires waiting out the separation, while irretrievable breakdown has no such requirement.

Residency requirement

At least one party must satisfy the residency rule before the court can grant a divorce under CGS 46b-44. The most common path is 12 months of residence in Connecticut before the final decree is entered (not necessarily before filing). Two shorter alternatives exist: domicile in Connecticut at the time of marriage followed by a return to the state, or a cause of divorce that arose after either spouse moved into Connecticut. The plaintiff files the complaint in the Superior Court in the judicial district where either spouse resides.

Waiting period and separation

Connecticut uses a docket-based timing rule rather than a strict day-count from filing.

For contested cases on the regular docket, the matter cannot be heard sooner than 90 days after the return date (the court date stamped on the summons when the case is opened). For uncontested or nonadversarial joint dissolutions, the waiting period shrinks to 30 days from the return date.

Even on the regular docket, spouses do not always have to wait out the full 90 days. If both spouses attest under oath that they have reached a full agreement covering every term of the divorce, they can file a Motion to Waive Statutory Time Period by Agreement of the Parties (Form JD-FM-247) under CGS 46b-67 and ask the court to enter the decree sooner.

A separation requirement is a different concept entirely, and Connecticut largely avoids it. There is no separation requirement for the irretrievable-breakdown ground. The only time a separation period matters is if a spouse chose the 18-months-apart incompatibility route described above, but that is an alternative, not a prerequisite for the common no-fault path.

How property is divided

Connecticut is an equitable distribution state. That means a court divides marital property fairly, taking into account the circumstances of each case, rather than splitting everything down the middle. Connecticut is not one of the nine community property states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin), so there is no automatic 50/50 rule.

The court considers all property, including property brought into the marriage or received as a gift or inheritance, when fashioning an equitable award under CGS 46b-81. Relevant factors include the length of the marriage, the age and health of the parties, occupation and earning capacity, the causes of the breakdown, and the contribution of each spouse to the marital estate. A spouse's waste or dissipation of assets can also affect the outcome.

Separate property is not automatically off the table in Connecticut. The court has broad discretion to assign any property to either party as justice requires, which makes the distinction between marital and separate assets less absolute here than in some other states.

Alimony, custody, and child support

Alimony (called "alimony" in Connecticut statutes), custody, and child support are resolved as part of the divorce or in a related proceeding. A court may award temporary alimony during the case and permanent or time-limited alimony in the final decree. For details on how Connecticut calculates and awards spousal support, see the Connecticut alimony laws page.

Child custody is determined under the "best interests of the child" standard. Connecticut courts favor joint legal custody in most cases, though physical custody arrangements vary. For a full breakdown of parenting plans and the court's approach, see the Connecticut child custody laws page.

Child support in Connecticut follows the Income Shares model set out in the Child Support and Arrearage Guidelines. See the Connecticut child support laws page for current guideline worksheets and deviation criteria. Estimate your obligation with our Connecticut child support calculator.

How to file for divorce in Connecticut

The process follows several clear steps. First, confirm residency. One party must satisfy the 12-month residency requirement (or one of the two shorter alternatives) before the decree can enter.

Second, prepare and file the paperwork. The petitioning spouse (the plaintiff) files a Complaint for Dissolution of Marriage, a Summons (JD-FM-3), and a Notice of Automatic Orders (JD-FM-158) in the Superior Court clerk's office in the appropriate judicial district. Connecticut's Judicial Branch website provides self-help forms.

Third, serve the other spouse. The complaint and summons must be served on the defendant spouse, usually by a state marshal. The defendant has a set period to respond or appear.

Fourth, exchange financial disclosures. Both parties must complete a Financial Affidavit (JD-FM-6) and provide documentation of income, assets, debts, and expenses. This exchange must happen before any settlement or hearing.

Fifth, resolve or litigate. If the parties agree on all issues (property, alimony, custody, and child support), they submit a written settlement agreement for the court to approve. If they disagree, the matter proceeds through case management, mediation if ordered, and potentially a trial before a judge.

Sixth, obtain the final decree. Once the waiting period has passed and all issues are resolved, the court enters a Decree of Dissolution of Marriage. At that point the parties are legally divorced.
