Delaware offers two distinct legal pathways to end a marriage: annulment and divorce. An annulment in Delaware declares that a valid marriage never legally existed, while a divorce legally terminates a valid marriage under 13 Del. C. § 1506. The filing fee for both proceedings is $165 at Delaware Family Court, and at least one spouse must have resided in Delaware for 6 continuous months before filing under 13 Del. C. § 1504(a). However, annulment requires proving specific grounds such as fraud, mental incapacity, or a void marriage within strict time limits ranging from 90 days to 1 year, whereas divorce requires only demonstrating that the marriage is "irretrievably broken" under 13 Del. C. § 1505.

What Is an Annulment in Delaware?
An annulment in Delaware is a court decree that declares a marriage legally invalid from its inception, meaning the marriage is treated as though it never existed under 13 Del. C. § 1506. Unlike divorce, which ends a valid marriage, annulment erases the marriage from legal record entirely. Delaware Family Court grants approximately 50-100 annulments annually compared to over 3,500 divorces, making annulment relatively rare and reserved for specific circumstances involving fraud, incapacity, or prohibited marriages.
The practical effect of obtaining an annulment versus a divorce in Delaware differs significantly in how you represent your marital status afterward. Following an annulment, you may legally state that you were never married to that person. Following a divorce, you must disclose that you were previously married and are now divorced. This distinction matters for immigration applications, security clearances, religious considerations, and personal preference.
Delaware law distinguishes between void marriages (automatically invalid) and voidable marriages (valid until annulled). Void marriages under 13 Del. C. § 101 include marriages between close relatives (ancestors, descendants, siblings, half-siblings, uncles, aunts, nieces, nephews, or first cousins) and bigamous marriages where one spouse was already legally married. Voidable marriages require court action to invalidate and include marriages involving fraud, mental incapacity, intoxication, or physical incapacity to consummate.
Grounds for Annulment in Delaware
Delaware law under 13 Del. C. § 1506(b) establishes six specific grounds for annulment, each with distinct filing deadlines and evidentiary requirements. The court must grant an annulment if the petitioner proves any of these grounds by a preponderance of the evidence, meaning more likely than not (greater than 50% probability).
Mental Incapacity or Intoxication
A marriage may be annulled when one spouse lacked the mental capacity to consent due to mental illness, cognitive impairment, or intoxication from alcohol or drugs at the time of the ceremony. The aggrieved spouse must file within 90 days of discovering the incapacity. Evidence may include medical records, witness testimony about the spouse's condition during the ceremony, toxicology evidence, or expert psychiatric evaluation. The court examines whether the affected party understood the nature and consequences of the marriage contract.
Physical Incapacity to Consummate
Either spouse may seek annulment when one party was physically unable to consummate the marriage through sexual intercourse, provided the other spouse did not know of this condition before marriage. The filing deadline is 1 year after discovering the incapacity. Medical documentation is typically required, and the incapacity must be permanent rather than temporary. Refusal to consummate does not qualify; the ground specifically requires physical inability.
Underage Marriage Without Consent
Marriages involving a party under 18 years old without proper parental, guardian, or judicial consent may be annulled. Only the underage party or their parent or guardian may file, and the action must commence within 1 year of the marriage date. If the underage party "confirms" the marriage after reaching legal age (typically by continued cohabitation), annulment becomes unavailable. Delaware requires individuals to be at least 18 to marry without parental consent.
Fraud or Misrepresentation
Annulment is available when one party induced the other into marriage through fraudulent acts or misrepresentations that go "to the essence of the marriage." The defrauded spouse must file within 90 days of discovering the fraud. Not all lies qualify; the fraud must concern fundamental aspects of the marriage such as the ability or intent to have children, concealment of a serious criminal history, misrepresentation of religious beliefs central to the marriage agreement, or hiding a serious communicable disease. Financial misrepresentations generally do not qualify unless extraordinarily egregious.
Duress, Threats, or Coercion
A marriage entered under duress, threats, or coercion may be annulled if the aggrieved party files within 90 days of becoming free from the coercive circumstances. The petitioner must demonstrate that they married only because of fear of harm to themselves or others, and that they would not have consented to the marriage absent the threats. Arranged marriages do not automatically qualify; actual threats or force must be proven.
Marriage Entered as Jest or Dare
Delaware uniquely recognizes annulment for marriages entered as a joke, jest, or dare where neither party intended to create a legal marriage. The aggrieved party must file within 90 days of the ceremony. This ground is rarely successful because most marriage ceremonies create binding obligations regardless of subjective intent, and courts require substantial evidence that no genuine marital intent existed.
Void Marriages (No Time Limit)
Marriages that are void under 13 Del. C. § 101 may be annulled at any time before the death of either party. Void marriages include bigamous marriages (where one party was already legally married), marriages between prohibited relatives, and marriages where one party was on probation or parole without the required consent. Either party may petition for annulment of a void marriage, and the court must grant the decree once the prohibited relationship is proven.
Annulment Filing Deadlines Summary
| Ground for Annulment | Who May File | Filing Deadline |
|---|---|---|
| Mental incapacity/intoxication | Aggrieved spouse or legal representative | 90 days after discovery |
| Physical incapacity | Either spouse | 1 year after discovery |
| Underage marriage | Underage party or parent/guardian | 1 year after marriage date |
| Fraud/misrepresentation | Defrauded spouse | 90 days after discovery |
| Duress/threats/coercion | Aggrieved spouse | 90 days after becoming free |
| Jest or dare | Aggrieved spouse | 90 days after ceremony |
| Void marriage (bigamy, incest) | Either spouse | Any time before death |
How Divorce Differs from Annulment in Delaware
Divorce in Delaware legally terminates a valid marriage, acknowledging that the marriage existed but is now irretrievably broken under 13 Del. C. § 1505. Delaware operates as a purely no-fault divorce state, meaning the only ground for divorce is that the marriage is "irretrievably broken" and reconciliation is improbable. This single ground can be established through four different methods: voluntary separation for 6 months, respondent misconduct, mental illness requiring institutional treatment, or general incompatibility with 6 months separation.
The most significant procedural difference between annulment and divorce in Delaware involves the waiting period. Divorce requires a 6-month separation period before the court will finalize the decree under 13 Del. C. § 1503(7), plus a mandatory 30-day "cooling off" period after filing. Annulment has no separation requirement, but imposes strict filing deadlines of 90 days to 1 year depending on the grounds. Separation in Delaware may occur while living under the same roof if the parties maintain separate bedrooms and abstain from sexual relations.
Delaware's no-fault system means you do not need to prove wrongdoing to obtain a divorce. Misconduct such as adultery, abuse, or desertion may help establish irretrievable breakdown without waiting 6 months for separation, but it creates a single no-fault divorce rather than a separate "fault-based" divorce. This contrasts sharply with annulment, which requires proving specific facts about conditions existing at the time of marriage.
Property Division in Annulment vs. Divorce
Delaware applies identical equitable distribution principles to both annulment and divorce proceedings under 13 Del. C. § 1513. The court divides marital property fairly but not necessarily equally, considering factors including marriage length, each party's contributions, economic circumstances, and any dissipation of assets. This means obtaining an annulment does not allow either party to avoid property division obligations.
Marital property subject to division includes assets and debts acquired during the marriage, regardless of title. Separate property (assets owned before marriage or received as gifts or inheritance) generally remains with the original owner. The equitable distribution analysis examines 11 statutory factors, with marriage duration being particularly relevant in short marriages that might qualify for annulment.
One practical difference emerges in very short marriages eligible for annulment. Because the marriage may have lasted only weeks or months before the fraud or incapacity was discovered, there may be minimal marital property to divide. The court considers the brevity of the union when making equitable distribution determinations. However, parties who commingle significant assets or make major purchases during even a brief marriage may face complex property division regardless of whether they pursue annulment or divorce.
Children's Rights: Legitimacy and Custody
Children born during an annulled marriage in Delaware remain legitimate under 13 Del. C. § 1506(d), explicitly protecting children from any legal stigma regardless of the parents' marital status determination. This statutory protection ensures that children of annulled marriages have the same inheritance rights, support entitlements, and legal status as children of valid marriages.
Custody and child support determinations proceed identically whether the underlying proceeding is annulment or divorce. Delaware Family Court applies the "best interests of the child" standard under 13 Del. C. § 722, examining factors including each parent's relationship with the child, the child's adjustment to home and school, and any history of domestic violence. Child support follows Delaware's income shares model, calculating support based on both parents' incomes and the number of children.
Parents in annulment proceedings involving minor children must complete Delaware's mandatory Parent Education Class before the court will finalize the decree. This 4-hour course covers co-parenting communication, the impact of separation on children, and conflict resolution strategies. The $50 course fee applies to both annulment and divorce cases involving children.
How to File for Annulment in Delaware
Filing for annulment in Delaware requires completing specific forms, paying the $165 filing fee (plus $10 court security fee), and serving the other party within 120 days. The petitioner must file in the Family Court of the county where either spouse resides, choosing between New Castle County (Wilmington), Kent County (Dover), or Sussex County (Georgetown).
The required forms include the Petition for Annulment (Form 222), Civil Case Information Statement (CIS), and if children are involved, an Affidavit of Custody/Visitation History. The petition must identify the specific statutory grounds for annulment and include sufficient facts to support each element. Unlike divorce petitions which broadly allege irretrievable breakdown, annulment petitions require detailed factual allegations about the fraud, incapacity, or other qualifying ground.
Service of process costs $10-$100 depending on the method. Options include sheriff service (approximately $40-60), private process server ($50-100), or certified mail with restricted delivery ($10-20). The respondent has 20 days after service to file an answer. If the respondent contests the annulment, the court schedules a hearing where both parties present evidence. Uncontested annulments where the respondent agrees or fails to respond may proceed more quickly, sometimes within 30-60 days of filing.
When to Choose Annulment vs. Divorce
Choosing between annulment and divorce in Delaware depends on your specific circumstances, timeline constraints, and long-term objectives. Annulment offers advantages when you have clear grounds and can meet the strict filing deadlines, particularly if representing yourself as "never married" matters for religious, immigration, or personal reasons.
Annulment may be preferable when the marriage was extremely brief and you discovered fraud or incapacity within the 90-day window, when religious beliefs make annulment more acceptable than divorce, when you wish to avoid the 6-month separation period (annulment has no separation requirement), or when the marriage involves bigamy or other void conditions. However, annulment requires proving specific facts that divorce does not, making it more difficult to obtain.
Divorce is typically the more practical choice when more than 90 days have passed since discovering fraud or incapacity, when you cannot prove any of the specific annulment grounds, when you simply want to end a valid marriage without proving wrongdoing, or when the separation period has already occurred naturally. The no-fault divorce system in Delaware makes divorce relatively straightforward once the 6-month separation requirement is satisfied.

| Cost Category | Annulment | Divorce |
|---|---|---|
| Filing Fee | $165 | $165 |
| Court Security Fee | $10 | $10 |
| Service of Process | $10-$100 | $10-$100 |
| Parent Education Class (if children) | $50 | $50 |

Fee waivers are available for low-income petitioners through Delaware's In Forma Pauperis application. Approval typically requires household income at or below 150% of the federal poverty level, which is approximately $23,895 for a single-person household in 2026.
Religious Considerations
Many individuals seek annulment for religious reasons, particularly in Catholic, Orthodox Jewish, and certain Protestant traditions that view divorce unfavorably. However, civil annulment in Delaware Family Court is entirely separate from religious annulment. A civil annulment does not automatically grant a religious annulment, and vice versa.
Catholic canon law, for example, has its own tribunal system and grounds for annulment that differ substantially from Delaware's civil requirements. A person may receive a civil divorce but a religious annulment, or a civil annulment but be denied a religious one. Individuals with religious concerns should consult both legal counsel for the civil proceedings and their religious institution for any separate religious process.
Impact on Immigration Status
Annulment versus divorce can significantly affect immigration cases, particularly those involving marriage-based green cards. United States Citizenship and Immigration Services (USCIS) examines whether marriages were entered in good faith, and an annulment based on fraud may raise questions about immigration fraud.
If you obtained immigration benefits through a marriage that is subsequently annulled for fraud, USCIS may review whether immigration fraud occurred. Conditional residents who obtained green cards through marriage less than two years old face particular scrutiny. Consult an immigration attorney before pursuing annulment if immigration benefits were obtained through the marriage. Divorce, while requiring disclosure of the marriage, generally poses fewer immigration complications than fraud-based annulment.
FAQs: Annulment vs. Divorce in Delaware
How long do I have to file for annulment in Delaware?
Delaware imposes strict filing deadlines ranging from 90 days to 1 year depending on the annulment grounds under 13 Del. C. § 1506. For fraud, mental incapacity, intoxication, duress, or jest, you must file within 90 days of discovering the condition. For physical incapacity, the deadline is 1 year after discovery. For underage marriage, filing must occur within 1 year of the marriage date. Void marriages (bigamy, incest) have no deadline.
Can I get an annulment if my spouse cheated on me?
No, adultery occurring after the marriage does not qualify as grounds for annulment in Delaware. Annulment requires proving conditions that existed at the time of the marriage ceremony, such as fraud, incapacity, or a void marriage. Adultery may, however, establish that the marriage is irretrievably broken for purposes of divorce under 13 Del. C. § 1505 without requiring the 6-month separation period.
Does an annulment affect child custody or support in Delaware?
Children born during an annulled marriage remain legitimate under Delaware law, with identical custody and support rights as children of divorced parents. The court determines custody based on the child's best interests under 13 Del. C. § 722, and child support follows Delaware's income shares model regardless of whether the parents' marriage was annulled or divorced.
Is property divided differently in annulment versus divorce?
No, Delaware applies the same equitable distribution principles to both annulment and divorce under 13 Del. C. § 1513. The court divides marital property fairly based on 11 statutory factors including marriage length, contributions, and economic circumstances. However, annulments typically involve shorter marriages with less accumulated marital property to divide.
Can I file for annulment if we've been married for years?
Generally no, because annulment grounds typically require filing within 90 days to 1 year of discovering the qualifying condition. The only exception is void marriages (bigamy or incest), which may be annulled at any time before either party's death. If years have passed since discovering fraud or incapacity, divorce is your only option.
What happens if my annulment is denied?
If the court denies your annulment petition, you may file for divorce instead. The denial does not prevent you from seeking divorce on the no-fault ground of irretrievable breakdown under 13 Del. C. § 1505. The 6-month separation period would begin from when you and your spouse last lived together as a married couple.
Do I need a lawyer for annulment in Delaware?
While not legally required, an attorney is strongly recommended for contested annulments due to the burden of proof requirements. Annulment requires proving specific facts about fraud, incapacity, or void conditions, which demands evidence, witness testimony, and legal argument. Uncontested annulments where both parties agree may be manageable pro se (without an attorney). Delaware Legal Help offers resources for self-represented litigants.
Can I get a Delaware annulment if we married in another state?
Yes, Delaware Family Court has jurisdiction over annulments if either spouse has resided in Delaware for at least 6 continuous months under 13 Del. C. § 1504(a). The location of the marriage ceremony does not determine where you can file. However, Delaware law governs whether grounds for annulment exist.
What's the difference between a void and voidable marriage?
A void marriage is automatically invalid under Delaware law and includes bigamous marriages and marriages between prohibited relatives under 13 Del. C. § 101. A voidable marriage is legally valid until annulled by court decree and includes marriages involving fraud, incapacity, or duress. Void marriages may be annulled at any time; voidable marriages have strict filing deadlines.
Does Delaware recognize legal separation as an alternative?
No, Delaware does not have a formal legal separation procedure. However, parties must be separated for at least 6 months before the court will finalize a no-fault divorce under 13 Del. C. § 1503(7). Separation may occur while living under the same roof if the parties maintain separate bedrooms and abstain from sexual relations. Neither annulment nor divorce requires a separate legal separation filing.
