What is Annulment?

An annulment declares a marriage legally invalid from its inception, treating it as though it never existed. Unlike divorce, which ends a valid marriage, annulment requires proving specific defects—fraud, bigamy, incest, duress, mental incapacity, or non-consummation—existed when the marriage occurred.

In the United States, annulment laws vary significantly by state. California Family Code § 2210 recognizes six grounds for voidable marriages, while New York Domestic Relations Law § 140 lists seven distinct categories. Florida has no annulment statute, relying entirely on case law precedent to define void and voidable marriages. Texas Family Code Chapter 6 requires filing within 90 days for underage marriages but allows unlimited time for bigamy claims.

In Canada, annulment falls under both federal and provincial jurisdiction. Ontario's Annulment of Marriages Act and Quebec Civil Code Article 380 govern procedural requirements, while the federal Marriage (Prohibited Degrees) Act (R.S.C., 1985, c. 19) establishes uniform prohibitions on incestuous marriages across all provinces and territories. Canadian courts distinguish between marriages that are void ab initio (automatically invalid) and voidable marriages requiring court declaration.

How Does Annulment Work in the United States?

Understanding Annulment in the United States

Annulment in the United States operates under state law, with each jurisdiction establishing distinct grounds, procedures, and time limits. Unlike divorce, which terminates a valid marriage, annulment declares the marriage was never legally valid from its inception under California Family Code § 2212, New York Domestic Relations Law § 140, Texas Family Code § 6.001, and similar state statutes.

Void vs. Voidable Marriages

US courts distinguish between void and voidable marriages, a distinction critical to understanding annulment rights. Void marriages are automatically invalid and include bigamous marriages (where one spouse was already legally married) and incestuous marriages between close blood relatives. Under California Family Code § 2200, marriages between parents and children, ancestors and descendants, and siblings are void ab initio. Texas Family Code § 6.201 similarly declares void any marriage entered into when a prior marriage remains undissolved.

Voidable marriages remain legally valid until a court grants an annulment. Common grounds include fraud, duress, mental incapacity, underage marriage without proper consent, and physical incapacity to consummate. California Family Code § 2210 enumerates six specific grounds: age, prior existing marriage, unsound mind, fraud, force, and physical incapacity. New York Domestic Relations Law § 140 adds mental illness continuing for five years as a seventh ground.

State-Specific Grounds and Requirements

California provides the most detailed statutory framework under Family Code §§ 2210–2212. Filing fees average $435–$450 in most counties (2025), with uncontested cases taking 4–12 weeks. Fraud-based annulments must be filed within four years of discovery per § 2211(d), while physical incapacity claims have a four-year deadline from the marriage date.

Texas Family Code Chapter 6 establishes specific grounds including: underage marriage (§ 6.102, requiring filing within 90 days), intoxication preventing consent (§ 6.105), impotence (§ 6.106), fraud/duress/force (§ 6.107), mental incapacity (§ 6.108), and concealed recent divorce (§ 6.109). The filing fee is approximately $300–$350 depending on county.

New York Domestic Relations Law Article 9 governs annulments with seven statutory grounds under § 140: bigamy (§ 140(a)), underage marriage (§ 140(b)), mental illness (§ 140(c)), physical incapacity (§ 140(d)), consent obtained by force or duress (§ 140(e)), fraud (§ 140(e)), and incurable mental illness for five years (§ 140(f)). Physical incapacity claims must be filed within five years of the marriage. New York filing fees total approximately $210 for the index number plus additional fees.

Florida uniquely has no annulment statute. Florida courts rely entirely on case law to adjudicate void and voidable marriages, applying common law principles derived from English law. Grounds recognized through Florida case law include bigamy, incest, fraud affecting the essence of the marital relationship, duress, underage marriage, permanent impotence, and mental incapacity. Without statutory guidance, filing procedures follow standard civil action rules under Florida Rule of Civil Procedure 1.070.

Time Limits and Statutes of Limitation

Time limits for seeking annulment vary by ground and state:

GroundCaliforniaNew YorkTexas
Underage Marriage4 years after reaching 18Until reaching legal age90 days from marriage
Fraud4 years from discovery3 years from discoveryNo specific limit
Force/Duress4 years from marriageAny time (before cohabitation)No specific limit
Physical Incapacity4 years from marriage5 years from marriageNo specific limit
BigamyDuring lifetime of partiesDuring lifetime of partiesNo time limit

These deadlines under California Family Code § 2211, New York Domestic Relations Law § 140, and Texas Family Code Chapter 6 are strictly enforced—missing them forecloses annulment as an option.

Financial and Property Implications

Unlike divorce, annulment does not automatically trigger equitable distribution laws. Because the marriage is declared never to have existed, standard community property (in states like California under Family Code § 760) or equitable distribution rules may not apply. However, courts protect innocent parties through the "putative spouse" doctrine.

Under California Family Code § 2251, a putative spouse—one who believed in good faith the marriage was valid—can receive property division and spousal support as if divorced. Texas Family Code § 2.401 provides similar protections. Courts divide property acquired during the putative marriage as if it were community property, preventing unjust enrichment.

Children born during an annulled marriage remain legitimate under California Family Code § 7540, Texas Family Code § 160.204, New York Domestic Relations Law § 24, and similar state statutes. Parenting time arrangements and child support obligations follow standard family law procedures regardless of the marriage's validity.

Filing Costs and Processing Times

Filing fees range from $160 (North Dakota) to $450+ (California), with the national average around $300–$350. Total costs for uncontested annulments typically range from $500 to $2,000 including filing fees, service of process ($50–$100), and basic attorney fees ($200–$400/hour for 5–10 hours of work). Contested annulments can exceed $5,000, particularly when proving fraud or mental incapacity requires expert testimony.

Processing times vary significantly: straightforward uncontested cases may conclude within 4–12 weeks, while contested annulments requiring hearings can take 6–18 months. Unlike California divorce (which requires a six-month waiting period under Family Code § 2339), annulments have no mandatory waiting period once grounds are established.

How Does Annulment Work in Canada?

This section covers the federal Divorce Act and provincial variations.

Understanding Annulment in Canada

Annulment in Canada operates under a complex framework combining federal and provincial jurisdiction. The federal government has exclusive authority over marriage and divorce under Constitution Act, 1867, Section 91(26), while provinces regulate the solemnization of marriage and property matters under Section 92(12). This division means annulment procedures vary by province while fundamental grounds remain consistent nationwide.

Federal Framework

The Marriage (Prohibited Degrees) Act (R.S.C., 1985, c. 19) establishes uniform rules prohibiting marriages between persons related by blood, adoption, or marriage within specified degrees. Section 2(2) declares such marriages void ab initio—automatically invalid without requiring court declaration. The federal Civil Marriage Act (S.C. 2005, c. 33) affirms marriage as "the lawful union of two persons to the exclusion of all others," implicitly rendering bigamous marriages void.

Unlike divorce, which is governed exclusively by the federal Divorce Act (R.S.C., 1985, c. 3), annulment procedures fall primarily under provincial superior court jurisdiction. This means Ontario, British Columbia, Quebec, and Alberta each have distinct procedural requirements despite sharing common substantive grounds.

Provincial Variations

Ontario governs annulments through the Annulment of Marriages Act (R.S.O. 1990, c. A.18), which incorporates English ecclesiastical law and grants the Superior Court of Justice exclusive jurisdiction. The Marriage Act (R.S.O. 1990, c. M.3), Section 7, prohibits issuing marriage licenses to persons lacking mental capacity due to intoxication or other impairment. Common grounds include: bigamy, prohibited degrees of relationship, lack of mental capacity, duress or fraud, underage marriage without parental consent (required under Section 5(2) for minors aged 16–18), and non-consummation due to incapacity. Ontario annulment costs typically exceed uncontested divorce costs because no "desk order" process exists—court appearances are mandatory.

Quebec applies civil law principles under the Civil Code of Québec (C.C.Q.). Article 380 C.C.Q. permits any interested person to request marriage nullity when formation conditions were not respected. Article 365 C.C.Q. requires free and enlightened consent from both parties. The three-year limitation period from marriage (Article 380 C.C.Q.) does not apply when the marriage violated rules of "public order." Quebec annulments must be filed in Superior Court, with jurisdiction established when one spouse is domiciled in Quebec at the time of application.

British Columbia applies common law principles through the Supreme Court of British Columbia. Grounds mirror other common law provinces: bigamy, prohibited degrees, lack of consent due to duress or intoxication, mental incapacity, fraud, and non-consummation. The Family Law Act (S.B.C. 2011, c. 25) ensures that even after annulment, former spouses may claim parenting arrangements, child support, spousal support, and property division under Part 5 (Property Division) and Part 7 (Child and Spousal Support).

Alberta follows similar common law principles, with the Court of King's Bench issuing Nullity Decrees. The Family Law Act (S.A. 2003, c. F-4.5) governs post-annulment support and property claims. At least one party must be an Alberta resident to file. Grounds include: bigamy, prohibited relationship degrees, consent obtained through threats to physical safety, intoxication preventing understanding of the ceremony, mistaken identity, non-consummation due to incapacity, and underage marriage without parental consent and without subsequent consummation.

Void vs. Voidable Marriages in Canada

Canadian law distinguishes between void ab initio marriages and voidable marriages. Void marriages are automatically invalid from their inception—no court order is required, though a declaration may be obtained for practical purposes. Examples include bigamous marriages (prohibited under Criminal Code Section 290) and marriages within prohibited degrees under the Marriage (Prohibited Degrees) Act.

Voidable marriages remain valid until a court declares them null. The Supreme Court of Canada in Kerr v. Kerr (1934) established that nullity suits "seek not to dissolve an existing marriage, but to declare that no marriage exists." Common voidable grounds include: fraud or misrepresentation about fundamental matters, duress or coercion, mental incapacity at the time of ceremony, and non-consummation due to physical or psychological incapacity.

Children, Support, and Property Rights

Annulment does not affect children's legitimacy. Under provincial family law statutes, children born during void or voidable marriages retain full legal rights. Ontario's Family Law Act (R.S.O. 1990, c. F.3), Section 1, extends the definition of "spouse" to include persons in void or voidable marriages who entered in good faith, ensuring they can claim support.

Parenting arrangements (formerly "custody" under pre-2021 terminology) and decision-making responsibility continue to be determined based on the children's best interests under the Divorce Act, Section 16, and provincial equivalents. Child support follows the Federal Child Support Guidelines (SOR/97-175) regardless of the marriage's validity.

Spousal support claims following annulment vary by province. In Ontario, a spouse who entered the marriage in good faith may claim support under the Family Law Act despite the marriage being declared void. British Columbia's Family Law Act similarly permits support claims post-annulment. Property division depends on whether the "spouse" definition in provincial legislation encompasses void marriages.

Religious vs. Civil Annulment

Religious annulments granted by churches or other religious institutions have no legal effect in Canada. The Supreme Court of Canada has consistently held that civil marriage and its dissolution are matters of federal jurisdiction. A Catholic tribunal annulment, for example, does not alter legal marital status—only a civil court order or divorce accomplishes that. Individuals seeking to remarry after religious annulment must still obtain either a civil annulment or divorce to be legally free to marry.

Process and Costs

Annulment applications must be filed with provincial superior courts (Superior Court of Justice in Ontario, Superior Court in Quebec, Supreme Court in British Columbia, Court of King's Bench in Alberta). Unlike divorce, there is no simplified "desk order" process—annulments typically require court hearings and evidence presentation.

Costs exceed uncontested divorce fees. Ontario uncontested divorces may cost $500–$1,500 using the simplified procedure, while annulments commonly cost $3,000–$10,000+ due to mandatory litigation. Alberta and British Columbia report similar cost differentials. The requirement to prove specific grounds through evidence—often including witness testimony, medical records, or documentation of fraud—increases both time and expense.

Frequently Asked Questions About Annulment

What is the difference between annulment and divorce?

Annulment declares a marriage legally void from its inception under California Family Code § 2212, New York Domestic Relations Law § 140, or equivalent provincial statutes—treating it as though it never existed. Divorce ends a valid marriage. Annulment requires proving specific defects (fraud, bigamy, incapacity) existed when the marriage occurred.

Link to this question
How long do you have to file for an annulment?

Time limits vary by ground and jurisdiction. California Family Code § 2211 allows four years from fraud discovery. New York Domestic Relations Law § 140(d) requires physical incapacity claims within five years of marriage. Texas Family Code § 6.102 requires underage marriage claims within 90 days. Bigamy claims have no time limit in most jurisdictions.

Link to this question
How much does an annulment cost in the US?

Filing fees range from $160 (North Dakota) to $450+ (California). Total costs for uncontested annulments average $500–$2,000 including service of process and basic attorney fees. Contested annulments requiring hearings and expert testimony can exceed $5,000 according to 2025 court fee schedules.

Link to this question
What are valid grounds for annulment?

Common grounds under California Family Code § 2210, New York Domestic Relations Law § 140, and Texas Family Code Chapter 6 include: fraud affecting the marriage decision, bigamy, incest, marriage under duress or force, mental incapacity at the ceremony, intoxication preventing consent, physical incapacity to consummate, and underage marriage without proper consent.

Link to this question
Can I get an annulment in Canada?

Yes, but annulments are rare and require proving specific grounds under Ontario's Annulment of Marriages Act, Quebec Civil Code Article 380, or common law principles in other provinces. Grounds include bigamy, prohibited degrees (Marriage (Prohibited Degrees) Act), fraud, duress, mental incapacity, and non-consummation. Unlike divorce, there is no simplified desk order process.

Link to this question
What happens to property if a marriage is annulled?

Because annulment declares the marriage never existed, standard community property (California Family Code § 760) or equitable distribution rules may not apply automatically. However, putative spouse protections under California Family Code § 2251 and similar state doctrines allow innocent parties who believed the marriage was valid to receive property division and support.

Link to this question
Are children from an annulled marriage legitimate?

Yes. Under California Family Code § 7540, Texas Family Code § 160.204, New York Domestic Relations Law § 24, and Canadian provincial family law statutes, children born during annulled marriages retain full legal legitimacy. Parenting arrangements and child support obligations continue regardless of the marriage's validity.

Link to this question
How long does an annulment take?

Processing times vary by jurisdiction and complexity. Uncontested annulments typically take 4–12 weeks in most US states. Contested cases requiring hearings can take 6–18 months. Unlike California divorce (which requires a six-month waiting period under Family Code § 2339), annulments have no mandatory waiting period once grounds are established.

Link to this question
Is a religious annulment the same as a legal annulment?

No. Religious annulments granted by churches or religious tribunals have no legal effect in the US or Canada. Under federal jurisdiction in both countries, only civil court orders dissolve marriages legally. Individuals must obtain civil annulment or divorce to be legally free to remarry, regardless of religious declarations.

Link to this question
What is a putative spouse?

A putative spouse is someone who believed in good faith their marriage was legally valid. Under California Family Code § 2251, Ontario's Family Law Act Section 1, and similar provisions, putative spouses may claim property division, spousal support, and other rights despite the marriage being declared void—preventing unjust enrichment of the other party.
