In Connecticut, an annulment legally declares that a marriage never existed, while a divorce ends a valid marriage. Connecticut courts grant annulments only when specific grounds prove the marriage was void (automatically invalid) or voidable (defective but requiring court action) under CGS § 46b-40. The state processed approximately 10,500 divorce filings in 2024 compared to fewer than 200 annulment petitions, reflecting how rarely annulment grounds apply. Divorce requires a 90-day waiting period and 12-month residency, while annulments bypass the waiting period but demand clear and convincing evidence of invalidity.

What Is the Difference Between Annulment and Divorce in Connecticut?
Annulment in Connecticut treats the marriage as if it never legally existed, while divorce terminates a valid marriage that existed during the time the parties were together. Under CGS § 46b-40(b), Connecticut courts must grant an annulment if the marriage is void or voidable under state law. A divorce decree acknowledges the marriage was valid and distributes marital rights accordingly. This distinction affects legal records, inheritance rights, and how Connecticut treats the former relationship. Courts require annulment petitioners to prove grounds by clear and convincing evidence, a higher standard than the simple assertion of irretrievable breakdown required for no-fault divorce.
The practical differences between annulment vs divorce in Connecticut extend beyond paperwork. Annulled marriages do not appear as prior marriages on future marriage license applications. Children from annulled marriages retain legitimacy under Connecticut law, protecting their inheritance and support rights. Property division follows the same equitable distribution principles regardless of whether the marriage ends through annulment or divorce under CGS § 46b-81. Alimony awards remain available in annulment cases when warranted by the circumstances.
Connecticut Grounds for Annulment: Void vs. Voidable Marriages
Connecticut law distinguishes between void marriages, which are automatically invalid from the start, and voidable marriages, which require court action to invalidate. Void marriages include bigamy (where one spouse was already legally married) and incestuous marriages prohibited by CGS § 46b-21. Voidable marriages involve defects like fraud, duress, or mental incompetence that give one party the right to seek annulment. The Connecticut Supreme Court established in 1990 that marriages between half-uncle and half-niece are void as incestuous under state law.
| Annulment Ground | Type | Evidence Required | Example |
|---|---|---|---|
| Bigamy | Void | Prior marriage certificate | Spouse was already married |
| Incest/Consanguinity | Void | Birth/DNA records | Marriage between siblings |
| Fraud | Voidable | Clear and convincing | Concealed inability to have children |
| Duress/Coercion | Voidable | Testimony, evidence | Forced into marriage under threat |
| Mental Incompetence | Voidable | Medical records, testimony | Lacked capacity to consent |
| Underage Without Consent | Voidable | Birth certificate, records | Minor married without parental consent |
| Physical Incapacity | Voidable | Medical evidence | Inability to consummate marriage |
| Defective Ceremony | Voidable | Marriage records | Invalid officiant or license |
Void Marriages in Connecticut
Bigamous and incestuous marriages are void from inception under Connecticut law, meaning they never had legal validity regardless of the parties' intentions. Bigamy occurs when one spouse was already legally married to another person at the time of the wedding, violating CGS § 53a-190. Connecticut prohibits marriage between parent and child, grandparent and grandchild, siblings (including half-siblings), aunt and nephew, and uncle and niece under CGS § 46b-21. The state also prohibits marriages between stepparent and stepchild and stepparent and stepgrandchild. An annulment judgment for a void marriage simply provides a court record that the marriage was never valid.
Voidable Marriages in Connecticut
Voidable marriages are legally valid until a court declares them invalid through annulment. Fraud represents the most common ground for voidable marriage annulment in Connecticut. Courts require that the fraud relate to matters essential to the marriage relationship, such as concealment of inability to have children or misrepresentation of religious conversion promises. Connecticut courts have held that misrepresentation about health conditions only justifies annulment when the condition makes it impossible to perform marital duties or poses a danger to health. A request by one spouse to join a particular religion after marriage does not constitute fraud under Connecticut case law.
Connecticut Grounds for Divorce: No-Fault and Fault-Based Options
Connecticut offers both no-fault and fault-based divorce grounds under CGS § 46b-40(c). The vast majority of Connecticut divorces proceed on no-fault grounds, specifically irretrievable breakdown of the marriage, which requires no proof of wrongdoing by either party. Filing on no-fault grounds typically results in faster resolution and lower legal costs compared to fault-based proceedings. Connecticut courts accept a simple statement that the marriage has broken down irretrievably, without requiring evidence of specific marital misconduct.
Connecticut's Nine Grounds for Divorce
- Irretrievable breakdown of the marriage (no-fault)
- Living apart for 18 continuous months with no reasonable prospect of reconciliation
- Adultery (defined as voluntary sexual intercourse with someone other than one's spouse)
- Fraudulent contract
- Willful desertion for one year with total neglect of duty
- Seven years' absence with no communication
- Habitual intemperance (substance abuse)
- Intolerable cruelty
- Sentence to imprisonment for life or commission of an infamous crime involving a violation of conjugal duty
Comparing Annulment vs Divorce Timelines
| Factor | Annulment | Divorce |
|---|---|---|
| Waiting Period | None | 90 days (waivable) |
| Evidence Required | Clear and convincing | Minimal (no-fault) |
| Average Timeline | 2-6 months | 3-18 months |
| Trial Likelihood | Higher | Lower |
| Complexity | More complex | Simpler process |
Connecticut Residency Requirements for Annulment and Divorce
Connecticut requires at least one spouse to have been a state resident for 12 months before the court can enter a final divorce decree under CGS § 46b-44. You may file the divorce petition before completing 12 months of residency, but the court will not finalize the divorce until the requirement is satisfied. This means filing after 9 months of residency can work if your case takes at least 3 additional months to resolve. The same residency rules apply to annulment cases filed in Connecticut courts.
Connecticut law provides alternative ways to satisfy residency requirements. If you were domiciled in Connecticut at the time of your marriage and returned with intent to remain permanently, you may file immediately. Similarly, if the cause for divorce or annulment arose after either party moved to Connecticut, you may file without waiting for the 12-month period. Military personnel who were Connecticut residents when entering service are deemed to have continuously resided in the state during their service under the statute.
Filing Fees and Court Costs in Connecticut
The Connecticut divorce filing fee is $350 as of March 2026, according to the Connecticut Judicial Branch. Service of process through a state marshal costs approximately $50 to $100, bringing minimum court costs to approximately $400 to $450. These fees apply equally to divorce and annulment filings. Contested cases involving custody, property disputes, or extensive litigation can generate additional costs for motions, subpoenas, and trial preparation. Verify current fees with your local Superior Court clerk before filing.
Fee Waiver Availability
Connecticut offers fee waivers through Form JD-FM-75 for filers meeting specific income criteria. Applicants with income below 125% of the federal poverty level or those receiving state assistance qualify for fee waivers. Waivable costs include the entry fee, filing fee, service of process costs, and parenting education program fees. The parenting education program costs approximately $150 per parent and is mandatory for divorcing parents with children under 18. Fee waivers can reduce total filing costs from over $400 to zero for qualifying applicants.
| Cost Component | Standard Amount | Waivable? |
|---|---|---|
| Filing Fee | $350 | Yes |
| Service of Process | $50-$100 | Yes |
| Parenting Education (if children) | $150/parent | Yes |
| Attorney Fees (if hired) | $250-$450/hour | No |
| Total Minimum Court Costs | $400-$450 | Partially |
The 90-Day Waiting Period: Divorce vs. Annulment
Connecticut imposes a mandatory 90-day waiting period before finalizing divorce cases, measured from the return date of the complaint. This waiting period does not apply to annulment cases, which can proceed directly to hearing once the matter is ready for trial. The waiting period reflects Connecticut's policy of providing time for potential reconciliation in divorce cases. Annulments bypass this requirement because they involve marriages that should not have occurred in the first place.
Waiving the 90-Day Waiting Period
Connecticut courts can waive the 90-day waiting period under specific circumstances outlined in CGS § 46b-67(b). Both parties must attest under oath that they have reached agreement on all terms of the divorce to request a waiver using Form JD-FM-247. When one spouse fails to file an appearance within 30 days of the return date, the filing spouse may request a waiver using Form JD-FM-272. The expedited non-adversarial divorce process allows finalization after just 30 days for couples meeting strict criteria: marriage of 8 years or less, no children, combined net property value under $35,000, and no defined benefit pension plans.
Property Division in Annulment vs. Divorce
Connecticut applies equitable distribution principles to property division in both divorce and annulment cases under CGS § 46b-81. The court divides property in a manner deemed fair, which does not necessarily mean equal. Connecticut is an all-property state, meaning the court can divide any asset owned by either spouse regardless of when or how it was acquired. Pre-marital property, inheritances, and gifts are all subject to division, unlike the law in most other states.
The 12 Statutory Factors for Property Division
Connecticut courts must consider 12 statutory factors when dividing property:
- Length of the marriage
- Causes for the annulment or dissolution
- Age of each party
- Health of each party
- Station in life of each party
- Occupation of each party
- Amount and sources of income
- Earning capacity and vocational skills
- Education and employability
- Estate and liabilities of each party
- Needs of each party
- Opportunity for future acquisition of capital assets and income
Property division orders are final and cannot be modified after the decree is entered, unlike alimony or child support orders. Getting property division right during the initial proceedings is critical because Connecticut law does not authorize post-judgment modification of property awards.
Children's Rights in Annulment Cases
Children born during annulled marriages retain full legitimacy under Connecticut law, protecting their inheritance rights, child support claims, and legal relationship with both parents. Connecticut courts apply the same best interests of the child standard to custody and visitation decisions regardless of whether the parents' marriage ends through annulment or divorce. Child support calculations follow the Connecticut Child Support Guidelines equally in both proceedings. Parents completing annulment with minor children must attend the mandatory parenting education program, just as divorcing parents must.
When to Choose Annulment Over Divorce in Connecticut
Annulment may be preferable when specific grounds exist and the parties wish to treat the marriage as never having occurred legally. Religious considerations often motivate annulment requests, as some faiths do not recognize civil divorce. Legal annulment in Connecticut is separate from religious annulment, and obtaining one does not guarantee the other. Annulment suits parties who discovered fraud, bigamy, or other fundamental defects shortly after marriage and want clean legal records.
Divorce remains the appropriate choice for the vast majority of Connecticut couples ending their marriages. Most marriages do not involve the specific defects required for annulment grounds. The no-fault divorce process is simpler, less expensive, and does not require proving specific allegations. Attempting annulment without valid grounds wastes time and money, as courts will dismiss petitions that fail to establish void or voidable marriage status.
How to File for Annulment or Divorce in Connecticut
Filing for annulment or divorce in Connecticut begins with submitting a complaint to the Superior Court in the judicial district where either spouse resides. The filing party (plaintiff) must complete the Summons (Form JD-FM-3) and either the Complaint for Dissolution of Marriage or Complaint for Annulment. Service of process must be completed by a state marshal or through acceptance of service signed by the defendant spouse. The return date, typically set 6 to 8 weeks after filing, marks the official start of the case.
Required Forms and Documents
- Summons (JD-FM-3)
- Complaint for Dissolution or Annulment
- Notice of Automatic Court Orders (JD-FM-158)
- Financial Affidavit (JD-FM-6)
- Parenting Education Program Certificate (if children involved)
- Settlement Agreement (if uncontested)
- Fee Waiver Application (JD-FM-75, if applicable)
Frequently Asked Questions
How long does an annulment take in Connecticut compared to divorce?
Connecticut annulments typically take 2 to 6 months when grounds are clear and evidence is available, while uncontested divorces average 3 to 6 months and contested divorces run 9 to 18 months. Annulments bypass the 90-day waiting period but require stronger evidence, potentially adding time for trial preparation. The actual timeline depends on court scheduling, complexity of property division, and whether custody issues exist.
Can I get an annulment in Connecticut if my spouse committed adultery?
Adultery is not grounds for annulment in Connecticut but is one of nine statutory grounds for divorce under CGS § 46b-40. Annulment requires proving the marriage was void (bigamy, incest) or voidable (fraud, duress, incompetence) at its inception. Adultery occurs after the marriage begins and therefore supports divorce rather than annulment. You may file for divorce on adultery grounds or simply assert irretrievable breakdown.
What is the filing fee for annulment vs divorce in Connecticut?
Connecticut charges the same $350 filing fee for both annulment and divorce petitions as of March 2026. Service of process adds $50 to $100 through a state marshal. Fee waivers are available for both proceeding types through Form JD-FM-75 for applicants with income below 125% of the federal poverty level. Verify current fees with your local Superior Court clerk before filing.
Does Connecticut require separation before divorce?
Connecticut does not require physical separation before filing for divorce on no-fault grounds. Spouses may file citing irretrievable breakdown while still living together. Living apart for 18 continuous months constitutes separate grounds for divorce under CGS § 46b-40(c)(2), but this separation is not a prerequisite for other divorce grounds. Many couples continue sharing a residence during divorce proceedings for financial or practical reasons.
How is property divided in a Connecticut annulment?
Property division in Connecticut annulments follows the same equitable distribution rules as divorce under CGS § 46b-81. Connecticut is an all-property state, allowing courts to divide any asset either spouse owns regardless of when acquired. Courts consider 12 statutory factors including marriage length, each party's income and needs, and contributions to property acquisition. The court aims for fair division, not necessarily equal division.
Can I get alimony if my marriage is annulled in Connecticut?
Connecticut courts can award alimony in annulment cases just as in divorce proceedings. Alimony determinations consider factors including the length of the marriage (or cohabitation), each party's income and earning capacity, age and health, and causes for the annulment. Courts have discretion to award temporary, rehabilitative, or permanent alimony based on the circumstances. Short marriages resulting in annulment typically result in limited or no alimony awards.
What happens to children if a marriage is annulled in Connecticut?
Children born during annulled marriages retain full legal rights under Connecticut law, including legitimacy, inheritance rights, and entitlement to child support. Custody and visitation follow the same best interests of the child standard applied in divorce cases. Child support calculations use the Connecticut Child Support Guidelines regardless of whether the marriage ends through annulment or divorce. Both parents must complete the parenting education program when minor children are involved.
How do I prove fraud for a Connecticut annulment?
Proving fraud for Connecticut annulment requires clear and convincing evidence that one spouse made material misrepresentations about matters essential to the marriage. Courts have accepted fraud claims involving concealment of inability to have children, misrepresentation of intent to convert religions, and hidden felony convictions. General dissatisfaction or discovery of character flaws after marriage does not constitute fraud. Connecticut courts require that the fraud relate directly to marital duties or fundamentally change the nature of the relationship.
Is there a time limit to file for annulment in Connecticut?
Connecticut has no statutory deadline for filing annulment petitions, unlike some states that impose time limits after discovering annulment grounds. However, waiting too long to file may weaken your case, as courts may question why you remained in a marriage you claim was invalid. Prompt filing after discovering grounds such as bigamy or fraud strengthens the annulment petition. Connecticut courts have granted annulments for marriages performed years earlier when valid grounds existed from inception.
Can I file for divorce and annulment simultaneously in Connecticut?
You may file alternative claims for annulment and divorce in Connecticut, requesting the court grant annulment if grounds are proven or divorce if annulment grounds are insufficient. This approach protects against dismissal if annulment evidence proves inadequate. Courts will first evaluate annulment grounds and proceed to divorce only if annulment is denied. Filing fee ($350) covers both claims when filed together in a single complaint.
