UBE Marriage Requirements and Annulment
Last updated: May 2, 2026
Marriage Requirements and Annulment questions are one of the highest-leverage areas to study for the UBE. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.
The rule
To create a valid ceremonial marriage, the parties must satisfy substantive capacity requirements (legal age, mental capacity, single status, and not within a prohibited degree of consanguinity) and procedural formalities (a marriage license and solemnization by an authorized officiant before witnesses). A defective marriage is either VOID (a legal nullity from inception, attackable by anyone at any time, even after a party's death) or VOIDABLE (valid until annulled in a court action brought by the aggrieved spouse, and ratifiable by continued cohabitation after the impediment is removed). Void grounds include bigamy, incest, and same-sex marriage bars (now unconstitutional under Obergefell v. Hodges, so this ground is largely historical), while voidable grounds include nonage, duress, fraud going to the essentials of marriage, and incurable physical incapacity. Federal constitutional doctrine (Loving v. Virginia; Obergefell) bars race-based and sexual-orientation-based marriage restrictions; the Uniform Marriage and Divorce Act (UMDA) and most state codes supply the elements tested.
Elements breakdown
Capacity to Marry (Substantive Requirements)
Both parties must possess the legal capacity to enter the marital contract at the moment of solemnization.
- Both parties of legal age (18, or younger with consent)
- Both parties of sound mind at ceremony
- Neither party currently married to another
- Parties not within prohibited degree of kinship
- Parties consent freely and voluntarily
Procedural Formalities
The state requires specific public-record formalities to validate the marriage absent a recognized exception.
- Valid marriage license issued by state
- Solemnization by authorized officiant
- Mutual present-tense exchange of vows
- Witnesses present (jurisdiction-dependent)
- License returned and recorded after ceremony
Void Marriage
A marriage that is a legal nullity from inception; no court decree is required to establish invalidity, though parties often seek a declaratory annulment for clarity.
- Defect existed at time of ceremony
- Defect is bigamy, incest, or other public-policy bar
- Marriage is void ab initio
- Attackable by any interested party
- Not curable by ratification or cohabitation
Common examples:
- Bigamy: prior undissolved marriage of either spouse
- Incest: marriage between ancestor/descendant or siblings
- Marriage by a party who lacked any capacity to consent (e.g., severe mental incapacity, in many jurisdictions)
Voidable Marriage
A marriage that is valid and produces all marital consequences until annulled in a judicial proceeding brought by the aggrieved spouse.
- Defect existed at ceremony
- Only aggrieved spouse may sue to annul
- Marriage valid until court decree
- Ratifiable by continued cohabitation
- Action subject to laches or statutory limits
Common examples:
- Nonage (underage party who has not ratified)
- Duress (forced marriage)
- Fraud going to essentials (concealed sterility, refusal to consummate, religion-required-for-procreation, or undisclosed pregnancy by another)
- Incurable physical impotence unknown to other spouse
- Intoxication or temporary mental incapacity at ceremony
Common-Law Marriage
In the minority of jurisdictions still recognizing it, an informal marriage formed without license or ceremony when the requirements are met.
- Capacity to marry (both parties)
- Present agreement to be married now
- Cohabitation as spouses
- Holding out publicly as married couple
- Formed in jurisdiction recognizing common-law marriage
Putative Spouse Doctrine
An equitable doctrine protecting a spouse who participated in a marriage ceremony in good faith believing it valid, despite an undiscovered impediment.
- Civil marriage ceremony performed
- At least one party in good faith
- Good-faith party unaware of impediment
- Marriage in fact void or voidable
- Putative spouse retains marital-like rights until learning of defect
Fraud Going to Essentials of Marriage
Misrepresentation about a matter so fundamental to the marital relationship that the deceived spouse would not have consented had the truth been known.
- Material misrepresentation by one party
- Concerns essentials of marital relationship
- Reliance by innocent spouse
- Discovery induces prompt action
- No ratification after discovery
Common examples:
- Concealed inability or refusal to have children
- Concealed pregnancy by another man
- Misrepresented religious commitment central to marriage
- Concealed prior crime affecting marital cohabitation in some jurisdictions
Annulment Decree Consequences
An annulment declares the marriage never existed, but most modern statutes (and UMDA §208) preserve certain incidents to protect children and innocent spouses.
- Marriage declared void ab initio
- Children retain legitimacy by statute
- Court may order property division
- Court may award maintenance in some states
- Putative spouse retains equitable rights
Common patterns and traps
The Void-vs-Voidable Cut
Every annulment question turns on this binary classification. Void grounds (bigamy, incest) cannot be cured, can be raised by anyone, and survive the death of a party for purposes of probate or social-security challenges. Voidable grounds (nonage, duress, fraud, impotence) require an action by the aggrieved spouse, are barred by ratification, and typically die with the party who could have raised them.
A wrong choice will say the marriage is "voidable" when the facts show bigamy or incest, or will say a third party (like a child or creditor) can challenge a voidable marriage when only the aggrieved spouse can.
The Fraud-Essentials Trap
Bar examiners love to test fraud annulments by giving facts where one party lied about wealth, employment, criminal history, immigration status, or personality — none of which qualify as essentials of marriage. Only lies going to sexual relations, capacity or willingness to have children, or fundamental religious commitment central to the marriage support annulment for fraud.
A choice will say "the marriage may be annulled because Reyes lied about being a millionaire" — wrong, because wealth is not an essential of marriage.
The Ratification Cure
Voidable marriages are cured when the aggrieved spouse, after learning the truth or attaining capacity, voluntarily continues marital cohabitation. The exam tests this with timing facts: how long did the spouse stay after discovery? Even brief continued cohabitation after the spouse turns 18 or learns of the fraud often ratifies and bars annulment.
A choice will grant annulment despite facts showing the aggrieved spouse stayed for months after discovering the impediment — ratification bars the action.
The Putative-Spouse Save
When a marriage is void or voidable but one spouse participated in good faith, the putative-spouse doctrine equitably preserves marital rights (property division, support, sometimes inheritance) until the good-faith spouse learns of the defect. This protects the innocent party even though the marriage itself fails.
A choice will deny all relief to the innocent spouse of a bigamist; the better answer recognizes putative-spouse rights to property accumulated during the period of good-faith belief.
The Common-Law Marriage Bait
Most states have abolished common-law marriage, but a recognizing state's marriage is portable under the Full Faith and Credit/place-of-celebration rule. Examiners test by setting facts in a non-recognizing state where the parties merely cohabited and held themselves out — that is NOT a common-law marriage, even if it would be in a recognizing state.
A choice will declare cohabiting parties married because they "held themselves out" — wrong if the conduct occurred in a non-recognizing state and they never were domiciled in a recognizing state during the relevant period.
How it works
Start by classifying the defect: is it void or voidable? That single classification dictates who can sue, when, and whether ratification rescues the marriage. Imagine that Patel marries Liu in March; six weeks later Patel discovers Liu was still married to a previous spouse whose divorce was never finalized. That marriage is VOID — bigamy is a public-policy bar that any interested party (Liu's first spouse, Patel, the state, even a probate creditor) can raise, and Patel and Liu cannot "ratify" it by continuing to live together. Contrast a vignette where 17-year-old Reyes marries without parental consent and then turns 18 and continues cohabiting for two years: that marriage is VOIDABLE for nonage, but Reyes ratified it by adult cohabitation, so a later annulment action fails. The fraud cases are the highest-yield trap: only fraud going to the essentials of marriage (procreation, sexual relations, religious centrality) supports annulment — fraud about wealth, social status, or personal history does not, because the law expects spouses to investigate non-essential matters before marrying.
Worked examples
Which of the following best describes the legal status of the Patel-Reyes marriage and who may challenge it?
- A The marriage is voidable for fraud, and only Patel may bring an annulment action because she is the aggrieved spouse.
- B The marriage is void ab initio for bigamy, and Liu, Patel, or the state may all challenge its validity. ✓ Correct
- C The marriage is valid because Patel entered it in good faith and the putative-spouse doctrine cures the defect.
- D The marriage is voidable for bigamy, valid until annulled, and only Patel may seek the decree.
Why B is correct: A bigamous marriage — one entered while a party has an undissolved prior marriage — is VOID ab initio in every U.S. jurisdiction, not merely voidable. Because it is a legal nullity, any interested party (including the prior spouse Liu, the new spouse Patel, the state, or even a probate creditor) may challenge it at any time. Putative-spouse doctrine may preserve some equitable rights for Patel as the good-faith party, but it does not validate the void marriage itself.
Why each wrong choice fails:
- A: This treats bigamy as fraud (voidable) rather than as the independent void ground it is. Even though Reyes did commit fraud, bigamy is a per se public-policy bar that voids the marriage outright, and any interested party — not just the aggrieved spouse — may challenge. (The Void-vs-Voidable Cut)
- C: The putative-spouse doctrine protects the good-faith spouse's equitable rights but does not transform a void marriage into a valid one. Patel's good faith preserves her ability to claim some marital-like property rights for the period before discovery; it cannot resurrect a marriage that public policy nullifies. (The Putative-Spouse Save)
- D: This combines the right defect (bigamy) with the wrong classification (voidable). Bigamy is void, not voidable — there is no need for a court decree to establish nullity, and standing to challenge is not limited to the aggrieved spouse. (The Void-vs-Voidable Cut)
How should the court rule on Liu's annulment petition?
- A Grant the annulment, because Liu lacked capacity to marry at the time of the ceremony and a defect at inception cannot be cured.
- B Grant the annulment, because the parties failed to comply with the home state's parental-consent formality.
- C Deny the annulment, because Liu ratified the marriage by continuing to cohabit with Reyes after attaining majority. ✓ Correct
- D Deny the annulment, because nonage marriages without parental consent are void and require no judicial decree.
Why C is correct: Nonage is a VOIDABLE ground for annulment — the marriage is valid until the aggrieved minor obtains a decree, and crucially, it is RATIFIABLE. When Liu turned 18 and continued to live with Reyes as a married couple for 14 months, performing classic marital acts (joint property, joint tax returns, holding out as spouses), she ratified the marriage and is now barred from annulling it. Voidable defects existing at inception are cured the moment the aggrieved party voluntarily continues the marriage after gaining capacity or learning the truth.
Why each wrong choice fails:
- A: This wrongly treats voidable nonage as if it were void and unratifiable. Voidable marriages — including those defective for nonage — are specifically curable by post-capacity cohabitation, which is exactly what occurred here. (The Ratification Cure)
- B: Place-of-celebration rules govern: most jurisdictions validate a marriage valid where contracted, and even if the marriage were technically defective for missing parental consent, that is at most a voidable defect — and Liu's adult ratification still bars relief. (The Common-Law Marriage Bait)
- D: Nonage marriages are voidable, not void. They produce all marital incidents until annulled and require an action by the aggrieved minor. Calling them void misclassifies the defect and would (incorrectly) allow third parties to challenge. (The Void-vs-Voidable Cut)
Will Patel's annulment action likely succeed?
- A Yes, because Reyes's misrepresentation went to the essentials of the marital relationship as Patel defined them at the outset. ✓ Correct
- B Yes, because any material misrepresentation that induces a party to marry supports annulment for fraud.
- C No, because misrepresentations about religion are personal beliefs and never qualify as fraud going to essentials.
- D No, because Patel and Reyes lawfully consummated the marriage and ratified it by remaining together for three weeks.
Why A is correct: Fraud supports annulment only when it goes to the ESSENTIALS of marriage — most commonly procreation, sexual relations, or, as here, a fundamental religious commitment that the deceived party clearly identified as central to the marital relationship before the ceremony. Patel made the religious-upbringing condition explicit, conditioned her consent on it, and acted promptly upon discovery without ratifying the marriage (she had not consummated and moved out immediately). The strict-essentials test is satisfied because the lie concerned the religious upbringing of children, a recognized essential category.
Why each wrong choice fails:
- B: This applies an ordinary contract-fraud standard, but marriage law uses a much narrower test. Material misrepresentations about wealth, character, employment, or background — though they would void an ordinary contract — do not support marriage annulment unless they go to the essentials of the marital relationship. (The Fraud-Essentials Trap)
- C: This overstates the rule. Religion does not automatically qualify, but a religious commitment central to procreation and child-rearing — explicitly conditioned on by the innocent party before marriage — falls within the recognized essentials category in most jurisdictions. (The Fraud-Essentials Trap)
- D: The facts say Patel had NOT yet consummated the marriage and moved out immediately upon discovery — there was no ratification. Even if there had been brief cohabitation, ratification requires the aggrieved party to continue marital relations AFTER discovering the truth, which did not occur. (The Ratification Cure)
Memory aid
"BIG VOID, small voidable" — BIGamy and Incest are VOID; everything else (nonage, duress, fraud-essentials, impotence, intoxication) is voidable. For voidable fraud, ask: "Does this lie go to SEX, KIDS, or RELIGION?" If not, it's not essentials.
Key distinction
Void vs. voidable: a void marriage never existed and needs no court action (though parties often seek a declaratory annulment), while a voidable marriage is fully valid — with all marital rights — until the aggrieved spouse obtains a decree, and is curable by ratification.
Summary
Marriage requires capacity plus formalities; defects make a marriage either void (bigamy, incest — attackable by anyone, not ratifiable) or voidable (nonage, duress, fraud-essentials, impotence — only aggrieved spouse sues, and continued cohabitation after discovery ratifies and bars annulment).
