You can get a divorce after 3 months of marriage in every U.S. state. No state sets a minimum length of marriage before you can file, so a three-month marriage ends through the same legal process as a thirty-year one. The short duration usually makes everything simpler: fewer assets to split, almost no chance of alimony, and a straightforward path to finalization. What actually controls your timeline is your state’s residency requirement and its mandatory waiting period, not the length of your marriage.
The Three Clocks That Control Your Timeline
Three separate rules can slow down a short-marriage divorce. They work independently and can stack.
Residency
Before a court can hear your case, at least one spouse must have lived in the state long enough to establish jurisdiction. A handful of states, including Alaska, South Dakota, and Washington, have no durational requirement at all, meaning you can file as soon as you establish residence with the intent to stay. Nevada and Idaho sit at the short end with six-week minimums. Several states require six months or a full year of continuous residency before you can file.1Justia. Residency Requirements for Divorce If you recently moved, this requirement alone could delay your filing by months.
Mandatory Waiting Period
Even after you file, most states impose a cooling-off period before a judge can finalize the divorce. The shortest are around 20 days (Idaho, Montana, West Virginia, Wyoming), and a large number of states fall in the 30-to-90-day range. California stands out with a six-month mandatory wait measured from the date your spouse is served. A few states, including Alaska, Florida, Nevada, and New Jersey, have no mandatory waiting period at all, meaning an uncontested case can theoretically close as soon as the paperwork is processed.
These waiting periods generally cannot be waived just because your marriage was short. The clock has to run.
Separation Requirements
Some states require you to live separately for a set period before you can be granted a no-fault divorce. North Carolina and South Carolina both require one year of separation. Louisiana requires 180 days, or 365 if children are involved. Virginia requires six months with no children, or one year with children.2Justia. Legal Separation in Divorce – 50-State Survey For a three-month marriage, a one-year separation rule means you’ll wait longer for the divorce than the marriage itself lasted. In those states, check whether fault-based grounds let you skip the separation period.
Should You Consider Annulment Instead?
A short marriage sometimes qualifies for annulment, but the bar is much higher than most people expect. A divorce ends a valid marriage. An annulment declares the marriage was never legally valid, and you need to prove a specific defect existed from the start.
Courts recognize annulment grounds like fraud (one spouse hid a prior marriage, a criminal record, or an inability to have children), duress (being forced or threatened into the ceremony), bigamy, or mental incapacity at the time of the wedding. Regretting the decision or discovering incompatibility does not qualify. Because annulments require proving those narrow circumstances, they’re far less common than divorces, and if you can’t meet the burden, you’ll need to file for divorce anyway.
One consequence worth knowing: if you get an annulment, the IRS treats you as if the marriage never existed. You’d need to file amended tax returns for any year affected, changing your filing status to single for those periods.3Internal Revenue Service.

The Faster Route: Summary Dissolution
Several states offer a streamlined process called summary dissolution or simplified divorce, designed for uncomplicated cases. A three-month marriage without children is often a textbook candidate. Exact eligibility varies by state, but the general requirements look like this:
- Short marriage, typically five years or less
- No minor children born to or adopted by the couple
- Total marital assets and debts fall below state-set thresholds
- Both spouses agree on dividing whatever property and debts exist, and both waive spousal support
Summary dissolution usually involves less paperwork, lower filing costs, and no court hearing. Ask the clerk’s office or check your state court’s website for simplified filing options before starting the full divorce process.
Grounds: Almost Always No-Fault
Every divorce requires a legal reason, or grounds. Every state allows no-fault divorce, where you cite irreconcilable differences or irretrievable breakdown and the court doesn’t require proof of who caused the split.4Legal Information Institute. Fault Divorce For a three-month marriage, no-fault is almost always the right choice. Fault grounds like adultery or cruelty require evidence, extend the timeline, and increase costs, and in most states they give you no meaningful advantage in the outcome. The main scenario where fault might matter is if your state imposes a lengthy separation period for no-fault divorce but allows immediate filing on fault grounds.
Property, Debts, and Spousal Support
Property division after three months is usually the simplest part. Courts split assets into separate property (what each spouse owned before the marriage, plus gifts and inheritances received individually) and marital property (what was acquired during the marriage).5Legal Information Institute. Marital Property After three months, the vast majority of what you own is separate property and stays with whoever brought it in.
Marital property after such a short period is usually limited to a few paychecks’ worth of income, maybe some household purchases, and any joint debts. If marital funds went toward paying down one spouse’s separate debt, like a car loan or student loan, the other spouse might have a reimbursement claim, though the amounts involved are typically small enough to resolve in a settlement.
Joint bank accounts and credit cards deserve immediate attention. Either spouse can legally withdraw from a joint account at any time, and both spouses remain liable for joint credit card debt regardless of who ran up the charges. Some states automatically issue restraining orders when a divorce is filed that prevent either party from depleting accounts or running up debt. Even where no automatic order exists, documenting all account balances and recent transactions before filing protects you from disputes later.
Alimony after a three-month marriage is exceptionally rare. The premise of spousal support is that one spouse became financially dependent during a longer marriage, often by leaving the workforce or supporting the other’s career. Three months doesn’t create that kind of dependency. Courts weigh length of marriage more heavily than almost any other factor in spousal support decisions, and after such a brief marriage the presumption is that both parties can return to their pre-marriage financial positions without help.
What Filing Actually Looks Like
Once you’ve met your state’s residency requirement, the process follows a standard sequence.
You start by filing a Petition for Dissolution of Marriage, sometimes called a Complaint for Divorce, with the circuit or family court in your county. The petition identifies both spouses, states the grounds for divorce, and outlines what you’re asking for regarding property and debts. Court filing fees range from under $100 in some states to over $400 in others. Many courts offer fee waivers for people who meet income guidelines.
After filing, you must formally deliver the divorce papers to your spouse through a process called service. Most states require a third party (a process server, sheriff’s deputy, or another adult not involved in the case) to hand-deliver the documents.6Justia. Serving and Answering a Divorce Petition If your spouse is cooperative, many states allow them to sign a waiver of service, which skips the formal delivery step and saves time.
A three-month marriage with few assets and no children is the ideal candidate for an uncontested divorce, where both parties agree on all terms. You draft a settlement agreement covering the division of any property and debts, both spouses sign, and the court reviews and approves it without a trial. This is where most short-marriage divorces end.
If you hit a snag, mediation is worth trying before litigation. A mediator can often resolve disagreements in a single session for a fraction of what a contested case costs.
Loose Ends: Taxes, Insurance, and Your Name
Your tax filing status depends on whether you’re married or divorced on December 31 of the tax year. If your divorce is finalized by that date, you file as single (or head of household if you qualify). If the divorce is still pending on December 31, you’re still legally married for tax purposes and must file as married filing jointly or married filing separately.3Internal Revenue Service. Publication 504 (2025), Divorced or Separated Individuals For a three-month marriage filing in the same year, rushing to finalize before year-end could affect which return you file.
If you’re covered under your spouse’s employer health plan, divorce is a qualifying event under the federal COBRA law that entitles you to continue that coverage for up to 36 months at your own expense.7U.S. Department of Labor. Separation and Divorce The plan must be notified of the divorce, and you generally have 60 days from receiving the COBRA election notice to sign up. COBRA premiums are typically expensive because you pay the full cost plus an administrative fee, but the coverage bridges the gap until you find your own plan through an employer or the health insurance marketplace.
If you changed your name when you married, the easiest time to change it back is during the divorce itself. Most states let you include a name-restoration request directly in your divorce petition or settlement agreement, and the judge writes the change into the final decree. You then use that court order to update your driver’s license, Social Security card, and other records. Skip this step during the divorce and you’ll likely need to file a separate name-change petition later, with its own filing fee and paperwork.
