Oregon courts grant annulments only when a marriage was never legally valid from its inception, while divorce (called dissolution) ends a valid marriage that existed but no longer works. Under ORS 107.015, annulment requires proving specific grounds such as bigamy, incest, fraud, or lack of capacity that existed at the time of the marriage ceremony. The filing fee for both annulment and divorce in Oregon is $301 as of January 2026, and Oregon has had no mandatory waiting period since the state repealed its 90-day requirement in 2011.

Understanding Annulment in Oregon
Oregon annulment declares that a marriage was never legally valid, essentially erasing it from legal existence. Under Oregon law, courts recognize two distinct categories of invalid marriages: void marriages under ORS 106.020 that are automatically invalid without court action, and voidable marriages under ORS 106.030 that require a court judgment to annul. Approximately 2-3% of Oregon marriage terminations are annulments rather than divorces, reflecting the narrow statutory grounds required. The annulment filing fee remains $301 statewide across all 36 Oregon circuit courts.
Void Marriages Under ORS 106.020
Oregon law declares certain marriages absolutely void from inception, meaning they never legally existed regardless of whether either party seeks court intervention. Under ORS 106.020, void marriages include bigamous unions where either party had a living spouse at the time of marriage, and incestuous marriages between first cousins or closer relatives by blood or adoption. These marriages are invalid whether or not a court declares them void, though obtaining a formal annulment judgment provides legal documentation that can be important for property rights, immigration matters, and future marriages.
Voidable Marriages Under ORS 106.030
Voidable marriages require active court intervention to annul because they appear valid on their face but suffer from defects that permit annulment. Under ORS 106.030, voidable grounds include lack of legal age to marry, lack of sufficient mental understanding to consent to marriage, consent obtained through force or physical duress, and consent obtained through fraud that goes to the essence of the marriage. Unlike void marriages, voidable marriages can be ratified by continued cohabitation after the condition is discovered or cured, which then bars annulment under ORS 107.015.
Oregon Annulment Grounds Explained
Oregon restricts annulment to specific circumstances that existed at the time of the marriage ceremony, not problems that developed afterward. Courts apply strict standards when evaluating annulment petitions because the legal consequence of declaring a marriage void ab initio (from the beginning) is significant. Understanding each ground helps determine whether annulment or divorce better fits your situation.
Bigamy (Existing Spouse)
A marriage is automatically void if either party was already married to another living person at the time of the ceremony. Under ORS 106.020(1), Oregon considers bigamous marriages absolutely void without need for court declaration. This ground applies even when one party genuinely believed their prior marriage had ended through divorce. Oregon courts will grant annulment regardless of how long the parties lived together as a married couple, and ratification through continued cohabitation does not cure this defect.
Incest (Prohibited Familial Relationships)
Marriages between first cousins or closer relatives by blood or adoption are void under ORS 106.020(2). Oregon law computes prohibited relationships using civil law rules, covering both whole and half-blood relatives. However, Oregon specifically exempts first cousins related solely through adoption (not blood), meaning two people who are adopted cousins but share no biological relationship may legally marry.
Fraud Going to the Essence of Marriage
Fraud that fundamentally deceived a party about the nature or purpose of the marriage constitutes grounds for annulment under ORS 106.030. Oregon courts have recognized actionable fraud in cases involving concealment of inability or refusal to have children, marriage solely to obtain immigration benefits without intent to build a life together, and concealment of serious criminal history or undisclosed existing marriage. Fraud must relate to a core aspect of the marital relationship. Simple lies about income, assets, or minor personal history typically do not qualify as grounds for annulment.
Force or Duress
Marriage consent obtained through physical force, threats of harm, or coercion renders the marriage voidable under Oregon law. Courts evaluate whether a reasonable person in the petitioner's position would have felt compelled to marry due to the threatened consequences. Examples include threats of physical violence against the person or their family members, threats to harm or take custody of existing children, and blackmail or extortion conditioning marriage on preventing disclosure of damaging information. The duress must be severe enough to overcome the free will of the person being coerced.
Lack of Legal Age
Oregon requires parties to be at least 18 years old to marry without parental consent, and at least 17 with parental and judicial consent. Marriages involving underage parties without proper authorization are voidable under ORS 106.030. However, if the underage spouse continues living with their partner after reaching legal age, they may be deemed to have ratified the marriage, barring later annulment claims.
Lack of Mental Capacity
A marriage is voidable when either party lacked sufficient mental understanding to consent to marriage at the time of the ceremony. This ground covers cognitive impairments, mental illness that prevented understanding of the nature and obligations of marriage, and temporary incapacity due to intoxication from alcohol or drugs. Oregon courts require evidence that the incapacity existed at the specific moment of marriage, not merely that the person has general mental health challenges.
Understanding Divorce (Dissolution) in Oregon
Oregon exclusively uses no-fault divorce grounds, meaning neither spouse must prove the other did something wrong to end the marriage. Under ORS 107.025, irreconcilable differences is the sole ground for dissolution of marriage in Oregon. Courts do not consider fault in deciding whether to grant a divorce, and Oregon explicitly prohibits courts from considering marital misconduct when dividing property under ORS 107.105.
No-Fault Divorce Process
Oregon divorce proceedings begin when one spouse files a Petition for Dissolution of Marriage with the circuit court, paying the $301 filing fee. The responding spouse then has 30 days to file an Answer after being served. Both parties must exchange complete financial disclosures within 30 days under ORS 107.089. If parties agree on all issues including property division, child custody, and support, an uncontested divorce can finalize in 4-8 weeks. Contested divorces requiring trial typically take 9-15 months to complete.
Oregon's Elimination of Waiting Period
Oregon repealed its mandatory 90-day waiting period in 2011, making it one of the faster states for finalizing divorce. Under the old statute ORS 107.065, courts could not hold hearings on divorce matters until 90 days after service on the respondent. Since repeal, divorces become final immediately upon the judge signing the judgment, with no cooling-off period required. This means spouses who agree on all terms can potentially complete their divorce within weeks of filing.
Comparing Annulment and Divorce Outcomes
While both annulment and divorce legally end a marriage, they produce different legal statuses and may have distinct consequences for specific situations. Understanding these differences helps determine which remedy better suits your circumstances.
Property Division Applies to Both
Oregon courts apply equitable distribution principles under ORS 107.105(1)(f) to divide property in both annulment and divorce cases. Despite the legal fiction that an annulled marriage never existed, Oregon protects both parties by still allowing property division. Courts presume both spouses contributed equally to property acquired during the relationship period and divide assets in a manner that is just and proper in all circumstances. Property division can result in unequal splits of 55/45, 60/40, or other ratios when circumstances warrant.
Children Remain Legitimate
Oregon law protects children born during an annulled marriage by maintaining their legitimacy. Under ORS 107.005, all children conceived or born of parents who married prior to a judgment declaring a marriage void are legitimate. This means annulment does not affect child custody determinations, child support obligations, or inheritance rights. Both parents remain legally responsible for their children regardless of whether the marriage ends through annulment or divorce.
Effect on Marital Status History
The primary distinction between annulment and divorce concerns how the former marriage appears in legal records. After divorce, a person's marital history shows a previous marriage that ended. After annulment, the marriage is treated as having never legally existed. This distinction matters for religious reasons for some individuals, potential immigration consequences in certain situations, specific employment or security clearance applications asking about marital history, and personal preference about how to characterize the relationship.
Oregon Residency Requirements
Oregon applies different residency standards depending on where the marriage was solemnized, making annulment vs divorce Oregon jurisdiction rules important to understand. Under ORS 107.075, couples married in Oregon face no minimum residency period, while those married elsewhere must establish Oregon residency.
Marriages Solemnized in Oregon
If the marriage ceremony occurred in Oregon, either spouse needs only to be a current resident of or domiciled in the state when filing. There is no waiting period or minimum duration requirement. This means Oregonians who married in-state can file immediately upon deciding to seek annulment or divorce.
Marriages Solemnized Outside Oregon
Couples who married in another state or country must satisfy a 6-month continuous residency requirement under ORS 107.075(2). At least one spouse must have lived in Oregon for six consecutive months immediately before filing. Proving residency requires documentation such as an Oregon driver's license, voter registration, utility bills, lease or mortgage documents, or state tax returns showing an Oregon address.
Filing Process and Costs
Both annulment and divorce cases begin in Oregon circuit court, following similar procedural steps despite their different legal theories. Understanding the filing requirements helps prepare for either type of case.
Filing Fees
The filing fee for both annulment and divorce petitions in Oregon is $301 as of January 2026, uniform across all 36 circuit courts. The responding spouse also pays $301 to file an Answer. Oregon courts waive filing fees for petitioners whose household income falls at or below 125% of the federal poverty level, which equals $19,506 for a single person in 2026. Fee waiver applications can be submitted with the initial filing.
Available Court Forms
Oregon provides standardized court forms for divorce proceedings through the Oregon Judicial Department website. However, there are no standardized Oregon court forms specifically for annulment petitions. This means annulment cases typically require attorney assistance to draft proper pleadings, adding potential costs compared to using free divorce forms for self-representation.
Where to File
Petitions must be filed in the circuit court of the county where either the petitioner or respondent resides under ORS 107.086. Oregon has 36 circuit courts covering all counties. Filing in the wrong county can delay proceedings and potentially result in dismissal.
When to Choose Annulment vs. Divorce
Choosing between annulment and divorce in Oregon depends primarily on whether valid annulment grounds exist and how quickly you discovered the problem. Annulment is not simply a faster or easier alternative to divorce. Courts require proof of specific defects that existed at the time of marriage.
Consider Annulment When
Annulment may be appropriate when you discover your spouse was already married to someone else at the time of your wedding, when fraud induced you to marry such as concealment of inability to have children or marriage solely for immigration benefits, when you were forced or threatened into marriage, when either party lacked mental capacity to understand the marriage commitment, or when prohibited family relationships existed. Acting promptly after discovering grounds is important, as continued cohabitation can constitute ratification that bars annulment claims.
Consider Divorce When
Divorce is the appropriate remedy when the marriage was initially valid but simply no longer works. This includes situations where spouses grew apart over time or developed irreconcilable differences, where adultery or other misconduct occurred during an otherwise valid marriage, where communication and relationship problems accumulated, or where one or both parties simply want to end the marriage without alleging defects in its formation. Oregon's no-fault system means you do not need to prove or even allege that your spouse did anything wrong.
Annulment Time Limitations
Oregon law does not specify a fixed statute of limitations for annulment petitions, but courts expect timely action after discovering grounds for annulment. The general principle requires filing promptly, typically within months to a few years of discovering the issue, depending on circumstances. Continued cohabitation after learning of fraud, underage status, or other voidable grounds can constitute ratification under ORS 107.015, permanently barring annulment.
For void marriages such as bigamy or incest, no time limit applies because these marriages are automatically invalid regardless of how long the parties lived together. However, obtaining a formal annulment judgment still requires filing a petition and proving the grounds.
FAQs: Annulment vs. Divorce in Oregon
Can I get an annulment in Oregon just because my marriage was short?
No, Oregon courts do not grant annulments based solely on marriage duration. Under ORS 106.030 and ORS 107.015, annulment requires proving specific grounds such as bigamy, fraud, duress, or incapacity that existed at the time of the wedding. Even marriages lasting only days or weeks require a divorce petition unless valid annulment grounds exist.
How much does an annulment cost compared to divorce in Oregon?
Both annulment and divorce petitions require the same $301 filing fee as of January 2026. However, annulment cases typically cost more overall because Oregon has no standardized annulment forms, requiring attorney assistance to draft pleadings. Attorney fees for annulment average $3,000-$7,000 compared to $2,500-$5,000 for uncontested divorce.
Does Oregon have a waiting period for annulment or divorce?
No, Oregon has no mandatory waiting period for either annulment or divorce. The state repealed its 90-day waiting requirement in 2011. Uncontested divorces can finalize in 4-8 weeks from filing. Annulment cases typically take 3-6 months due to the need to prove specific grounds through evidence and potentially testimony.
Will I still receive property division in an annulment?
Yes, Oregon courts apply equitable distribution under ORS 107.105(1)(f) to annulment cases just as they do in divorce. Despite the legal fiction that an annulled marriage never existed, courts divide property acquired during the relationship period fairly. The presumption of equal contribution applies regardless of whether the marriage ends through annulment or divorce.
Are children from an annulled marriage still legitimate in Oregon?
Yes, Oregon law specifically protects children born during annulled marriages. Under ORS 107.005, children conceived or born before an annulment judgment remain legitimate. Both parents retain full custody rights and child support obligations. Annulment does not affect paternity determinations or inheritance rights.
Can I get an annulment if my spouse lied about wanting children?
Possibly, if the fraud goes to the essence of marriage. Oregon courts have recognized concealment of inability or unwillingness to have children as potential grounds for annulment under ORS 106.030. However, you must prove your spouse intentionally deceived you about this fundamental issue before marriage. Simple changes of mind after marriage do not qualify.
How long do I have to file for annulment in Oregon?
Oregon has no fixed statute of limitations for annulment, but courts expect prompt action after discovering grounds. For voidable marriages involving fraud, duress, or incapacity, continued cohabitation after learning the truth can constitute ratification under ORS 107.015, barring future annulment claims. Filing within months of discovery is advisable.
Can I get an annulment for religious reasons if I do not qualify legally?
No, Oregon courts only grant annulments based on the statutory grounds in ORS 106.020, ORS 106.030, and ORS 107.015. Religious beliefs alone do not constitute legal grounds. However, you can pursue a religious annulment through your church separately from the legal divorce process. Both processes may be necessary if your religion requires annulment but legal grounds do not exist.
What happens to spousal support in an annulment vs. divorce?
Oregon courts can award spousal support in both annulment and divorce cases under ORS 107.105. Despite the legal theory that an annulled marriage never existed, courts retain authority to order transitional, compensatory, or maintenance support based on the same factors applied in divorce proceedings. Support awards depend on factors including marriage duration, income disparity, and standard of living.
Do I need a lawyer for an annulment in Oregon?
While not legally required, attorney representation is strongly recommended for Oregon annulment cases. The state provides no standardized annulment forms, unlike the free divorce forms available through the Oregon Judicial Department. Annulment also requires gathering evidence and proving specific grounds, which typically requires legal expertise. Oregon attorney fees for annulment average $3,000-$7,000.
