You cannot cancel a marriage within 30 days. No state offers a cooling-off period, a return window, or any procedure that lets you undo a wedding simply because you changed your mind soon after. If you want out of a marriage you just entered, the law gives you two options: annulment or divorce. Which one applies has almost nothing to do with how long you’ve been married and almost everything to do with what was true on the day of the ceremony.
The Two Real Options
People treat “annulment” and “divorce” as interchangeable, but they do different things. An annulment is a court’s declaration that a valid marriage never existed. A divorce ends a marriage that was legally valid. After a divorce, you were married and now you aren’t. After an annulment, in the eyes of the law, you were never married in the first place.
The length of the marriage is not the test for either one. A one-day marriage can only be annulled if a specific legal defect existed at the ceremony. A 20-year marriage can be annulled on the same grounds. The court looks at what was true when you got married, not at what has happened since.
When Annulment Is Actually Available
A court will only grant an annulment if you prove a specific legal defect existed at the time of the wedding. The recognized grounds are:
- Fraud or misrepresentation about something so fundamental that the other spouse would not have agreed to the marriage if they had known. Concealing an inability to have children, hiding a serious infectious disease, hiding a prior undissolved marriage, or marrying solely to obtain immigration benefits generally qualifies. Lying about income, personal habits, or character usually does not.
- Duress or coercion, where one party was forced or threatened into the marriage and did not freely consent.
- Mental incapacity, where one party could not understand the nature of the marriage contract because of severe mental illness, intellectual disability, or extreme intoxication.
- Undisclosed physical incapacity to consummate the marriage.
- Underage marriage without the required parental or judicial approval.
- Bigamy, where one spouse was already legally married to someone else.
- Incest, where the spouses are closely related by blood.
Bigamy and incest make a marriage void automatically. It was never legally valid, and technically you don’t need a court order to end it, though getting a formal declaration creates an official record and resolves questions about property. The other grounds make a marriage voidable, which means it is treated as valid until a court says otherwise. For those, you have to file, prove your case, and get a judge to invalidate the union.
“I regret it” and “we don’t get along” are not grounds. Neither is a rushed Las Vegas ceremony on its own. If nothing on the list above describes your situation, annulment is not available and divorce is the only path.
Act Fast: The Ratification Trap
If you do have grounds, the worst thing you can do is wait. Most states impose deadlines for filing annulment based on the specific ground. Fraud claims commonly must be filed within a set number of years after the fraud is discovered. Underage marriage claims often must be filed before the younger spouse turns 18 or within a short window after.
More dangerous than a filing deadline is ratification. If you discover that your spouse committed fraud, or that another ground for annulment exists, and you keep living together as a married couple, the court will treat that as acceptance of the marriage. Once ratified, annulment disappears as an option and divorce becomes your only way out. Continuing to share a home, share finances, and carry on as spouses signals to a judge that you’ve forgiven the defect. The moment you learn of a serious problem, the clock starts.
Ratification applies to voidable marriages, not void ones. A bigamous marriage stays void no matter how long the parties cohabitate afterward. But for fraud, duress, or mental incapacity, staying together after the truth comes out kills the annulment claim.
Divorce for a Very Short Marriage
If annulment grounds don’t apply, divorce is the way out, even after only a few weeks of marriage. A two-week marriage is just as eligible for divorce as a two-decade one.
Every state now allows no-fault divorce. You do not have to prove your spouse did anything wrong. You tell the court the marriage has broken down and cannot be repaired. The phrasing varies by state; the concept is the same everywhere.
Short marriages are usually simpler to divorce than long ones. There is typically little marital property to divide, spousal support is unlikely to be awarded, and the financial entanglement that complicates longer divorces barely exists. Simpler is not the same as instant, though.
Waiting Periods
Most states impose a mandatory waiting period between filing and finalization. These range from about 20 days in states like Florida, West Virginia, and Wyoming to six months in California and Delaware. Common waiting periods fall in the 30-to-90-day range. A few states, including Nevada, Illinois, Minnesota, and New York, impose no mandatory waiting period, though normal processing time still applies. Even when both spouses agree on everything, you cannot finalize the divorce until any waiting period expires.
Summary Dissolution
Some states offer a streamlined procedure called summary dissolution, designed for exactly this situation. Eligibility requirements vary but generally include a marriage of five years or less, no minor children, no real estate, limited marital property and debts (often capped at a specific dollar amount), and both spouses agreeing to waive spousal support. Where it’s available and you qualify, summary dissolution involves less paperwork, fewer court appearances, and lower costs than a standard divorce. Not every state offers it, so check whether yours does.
The Residency Problem for People Who Eloped
You cannot file just anywhere. Every state requires at least one spouse to have lived there for a minimum period before filing for divorce, ranging from six weeks in the most lenient states to a full year in the strictest. Many states also require residency in the specific county where you file.
This trips up people who married quickly while traveling. If you got married in Las Vegas but live in a state with a six-month residency requirement, you may need to wait before you can file at home. Annulment residency rules sometimes differ; in some states you can file for annulment in the state where the ceremony took place even if neither spouse lives there. Getting this wrong means the case gets dismissed.
Religious Annulment Is a Separate Track
A religious annulment and a civil annulment are different proceedings with different standards, and one has no effect on the other. A religious annulment, such as one granted by the Catholic Church, declares that a marriage was not sacramentally valid under church doctrine. It has no legal force. You can receive a religious annulment and still be legally married, and you can receive a civil annulment while your church still considers you married. If you need both, pursue them separately.
How the Filing Works
Starting an annulment or a divorce follows roughly the same steps. You file a petition with the family court in the county where you or your spouse lives. The petition identifies both spouses and states the legal basis for your request, whether that’s an annulment ground or irreconcilable differences.
Filing fees run from about $50 to $450, with most jurisdictions charging between $150 and $350. If you cannot afford the fee, you can request a fee waiver. Courts grant waivers to people who receive certain public benefits, whose household income falls below a set threshold, or who can show that paying would prevent them from meeting basic living expenses. File the waiver request at the same time as your petition.
After filing, you have to formally notify your spouse through a process called service. A neutral adult who is not involved in the case delivers a copy of the petition and a court summons in person. The summons tells your spouse how long they have to respond, typically 20 to 30 days. A professional process server generally costs $20 to $100; in some places the sheriff’s office will serve papers for a small fee. If your spouse cooperates, many states allow them to sign a written waiver acknowledging receipt, which skips the formal delivery.
When both spouses agree on everything, many annulments and short-marriage divorces can be resolved without a trial. If your spouse doesn’t respond within the deadline, you can ask the court for a default judgment. Either way, nothing is final until a judge signs the order.
