What is a no-fault divorce and how does it work?

Last updated 2026-07-09

What is a no-fault divorce, exactly?

A no-fault divorce ends a marriage without either spouse having to prove the other committed adultery, abandonment, cruelty, or any other marital fault. You tell the court the marriage is over and can't be fixed. The legal wording changes from state to state, but the idea is the same everywhere: you don't need a villain.

Most states use the phrase "irreconcilable differences." Others say "irretrievable breakdown of the marriage" or "incompatibility." California, which passed the first true no-fault law in the country in 1969 under the Family Law Act, uses "irreconcilable differences that have caused the irremediable breakdown of the marriage." ^[1] The words differ. The standard is identical.

Before no-fault existed, a spouse who wanted out had to allege and often prove something like adultery or extreme cruelty in open court. That meant airing private details before a judge, hiring investigators, and frequently exaggerating or flat-out inventing misconduct just to get the paperwork through. No-fault laws killed that requirement.

The opposite is a fault-based divorce, which still exists as an option in many states. Fault grounds can sometimes shift alimony or property division. But in practice most couples, even in states that allow fault, file on no-fault grounds because it's faster, cheaper, and less of a fight. More on that below.

Is no-fault divorce available in every state?

Yes. Every state allows no-fault divorce. New York was the last holdout, adopting no-fault grounds in October 2010. ^[2] Since that date, no American has been legally required to prove marital misconduct to get divorced.

States still differ in a few ways that matter:

Separation requirements. Some states make you live apart for a set period before you can file or before the divorce is granted. North Carolina requires one year of separation. ^[3] South Carolina requires one year on no-fault grounds. Louisiana's covenant marriage requires two years. Most states have no separation requirement at all.

Residency requirements. Every state requires at least one spouse to have lived in the state for a minimum period before filing. That runs from six weeks in Nevada to six months in most states, up to one year in several others.

Fault as an option. About 30 states still let you allege fault if you want to, and fault can matter in those states for dividing property or setting alimony. You can always choose no-fault instead. Nobody is forced to use fault grounds.

Here's the takeaway. Wherever you live, you can get a no-fault divorce. The only real variables are how long you wait and what the court charges to file.

State	No-fault ground language	Separation required?	Residency requirement
California	Irreconcilable differences	No	6 months [4]
Texas	Insupportability	No	6 months [5]
New York	Irretrievable breakdown (6+ months)	No (breakdown is 6 mo.)	1 year (or 2 yr. marriage in state) [2]
Florida	Irretrievable breakdown	No	6 months [6]
North Carolina	Irretrievable breakdown	1 year	6 months [3]
Illinois	Irreconcilable differences	No (6 mo. sep. creates presumption)	90 days
Nevada	Incompatibility	No	6 weeks

How does no-fault divorce differ from an uncontested divorce?

People mix up these two terms constantly, and the confusion makes sense. They're related, but they're not the same thing.

No-fault is a legal ground, meaning the reason you give the court for why the marriage is over. Uncontested means both spouses agree on all the terms: property, debts, children, support. You can have a no-fault contested divorce, where both parties agree the marriage is broken but fight bitterly over who keeps the house. You can also have an uncontested fault divorce in theory, though almost nobody does.

The combination you want, the one that keeps costs low and timelines short, is an uncontested no-fault divorce. Both spouses sign a settlement agreement covering everything, cite irreconcilable differences or whatever your state calls it, and submit the paperwork together or with one spouse serving the other without a dispute. The court reviews it, a judge signs it, and you're done.

For a closer look at the paperwork side, the divorce papers guide walks through what every state requires you to file.

What are the grounds for a no-fault divorce?

The ground is the legal reason you put on the divorce petition. For a no-fault divorce, that ground is almost always one of three things:

1. Irreconcilable differences (California, Texas, Illinois, most others) 2. Irretrievable breakdown of the marriage (Florida, New York, North Carolina, many others) 3. Incompatibility (Nevada, Oklahoma, a handful of others)

You don't have to explain what caused the breakdown. You don't have to list incidents. You don't have to prove anything. California Family Code section 2310 lists irreconcilable differences and incurable insanity as the only two legal grounds for divorce in that state, and once irreconcilable differences are established, the court "shall" grant the divorce. ^[1] Most states follow the same logic: you state the ground, the court accepts it, the marriage ends.

One thing trips people up. In states where a separation period creates a legal presumption of breakdown (Illinois uses six months, New York's law references a breakdown that has existed for at least six months), you don't have to actually prove the marriage has been over that long. The separation period, or your sworn statement that the breakdown has existed, is enough.

Fault grounds, by contrast, require evidence. Adultery, abandonment, extreme cruelty, habitual drunkenness, felony conviction. Each state has its own list. If you're wondering whether fault grounds might get you a better financial outcome in your state, run that by a divorce attorney before you file. The answer varies sharply by state and by judge.

What are the steps to file a no-fault divorce?

The process is more procedural than hard. Here's the general sequence for an uncontested no-fault divorce, which fits most states:

1. Confirm you meet residency requirements. One of you has to have lived in the state long enough. Check your state court's self-help center for the exact number. Most state court websites list it clearly.

2. Prepare the petition and settlement agreement. The petition (sometimes called a complaint or application) is the document that formally starts the case. It names both spouses, states the no-fault ground, and asks the court to grant the divorce. The settlement agreement, also called a marital settlement agreement or separation agreement, covers everything you've agreed on: property, debts, whether any alimony is owed, and, if you have kids, custody and support. Some states fold these into one packet. Others use separate forms.

3. File with the clerk and pay the filing fee. You file in the county where either spouse lives. Filing fees run from about $70 in Wyoming to over $400 in some California counties, with most states landing in the $150 to $350 range. ^[7] Some courts charge extra for service of process or document certification.

4. Serve your spouse (or have them waive service). Even in an uncontested case, the law requires formal notice to the other spouse. Usually the non-filing spouse signs an Acceptance of Service or Waiver of Service form, which means you skip hiring a process server.

5. Wait out any mandatory waiting period. Many states impose a waiting period between filing and final judgment. California's is six months from service of the petition. ^[4] Others are as short as 20 days (Texas) or 60 days (Florida). Some states have none.

6. Submit the final decree for the judge's signature. In a truly uncontested case, you usually don't appear in court. You submit a proposed final judgment or decree, the judge reviews it, signs it, and the clerk sends you certified copies. A few states require a brief hearing even for uncontested cases.

Services like DivorceClear offer a $149 document packet that prepares all the state-specific forms for you. Worth considering if you'd rather not spend hours figuring out which forms apply to your situation.

For a walkthrough of what each document does, the divorce papers guide covers it form by form.

How long does a no-fault divorce take?

Shorter than most people expect, as long as it's uncontested. Contested divorces can drag on for one to three years. Uncontested no-fault divorces usually finish in one to six months.

The biggest variable is your state's mandatory waiting period. California's six-month cooling-off window means even a couple that agrees on everything can't get a final decree in less than six months from service of the petition. ^[4] Texas has a 60-day waiting period from filing. Florida requires 20 days. Several states, including Nevada and Alaska, have no mandatory waiting period at all.

Court backlog is the other variable nobody talks about. In some high-volume counties, getting a judge to sign your final decree can take eight to twelve weeks even after you've submitted everything correctly. Rural counties tend to move faster. If speed matters, call the clerk's office and ask how long their current queue is for uncontested family law matters.

Minor children add time. Expect the process to run at least a few weeks longer than average no matter your state, because courts read parenting plans more carefully.

How much does a no-fault divorce cost?

Filing fees are the baseline, and your state or county court sets them. Across the country they run from about $70 to over $435. ^[7] A few examples:

• California (Los Angeles County): about $435 to file a petition ^[4]
• Texas: about $250 to $350 depending on county ^[5]
• Florida: about $408 in most counties ^[6]
• New York: about $335 ^[2]
• Illinois: about $289 in Cook County

If you genuinely can't afford the filing fee, every state has a fee waiver process. You submit a financial affidavit, and if your income is low enough (usually at or below 125% to 200% of the federal poverty level), the fee is waived. Ask the clerk's office or check your state court's self-help center.

Past the filing fee, your costs depend on how you handle the paperwork. Hiring a divorce lawyer for even an uncontested case typically runs $1,000 to $3,000 on the low end, and a lot more if things get complicated. Online document services cost $100 to $350 for the full packet. Doing it yourself from your state court's blank forms costs nothing beyond printing.

The total out-of-pocket for a true DIY uncontested no-fault divorce, filing fee plus a document service, usually lands somewhere between $300 and $700. That's the realistic range for most people reading this.

Can a spouse refuse or block a no-fault divorce?

No. This is one of the biggest practical effects of no-fault law. A spouse can't prevent you from getting divorced in a no-fault state by simply refusing to consent.

If your spouse doesn't respond to the divorce petition within the time allowed (usually 20 to 30 days after service), you can request a default judgment. The court then grants the divorce based on your petition alone, dividing property and resolving other issues under state default rules.

If your spouse does respond and contests the terms but not the divorce itself, the case becomes contested over those specific issues (property, children, support). The divorce still happens. The judge can rule on each contested issue, and no one can be kept married against their will.

The only real lever a reluctant spouse has is stalling by contesting terms, which runs up legal fees and stretches the timeline. That's a real cost. But the marriage still ends.

It wasn't always this way. Before no-fault laws, a spouse could sometimes block a divorce by denying fault allegations or by claiming a defense like recrimination (arguing the other spouse was also at fault). No-fault law wiped out those defenses.

Does no-fault divorce affect property division or alimony?

In most states, choosing fault or no-fault grounds has little or no effect on how property gets split or whether alimony gets awarded. Most states divide marital property under equitable distribution rules that focus on financial factors, not marital misconduct.

That said, in some states, marital misconduct can still be a factor a judge weighs when setting alimony or dividing property. Virginia bars a spouse who committed adultery from receiving spousal support in most cases, regardless of the divorce grounds used. ^[8] North Carolina lets a judge consider marital fault in alimony decisions. If you're in a state where fault genuinely shifts financial outcomes and you think you have a strong fault claim, explore it with an attorney before you file on no-fault grounds.

For most couples filing an uncontested case, though, this is theoretical. You're dividing what you both agree to divide, and the court is mostly checking that the agreement doesn't wildly shortchange one spouse or harm the children.

For support questions, the alimony guide covers how courts calculate spousal support and what factors they actually weigh. If children are involved, a child support calculator gives you a realistic ballpark before you finalize anything.

What is the history of no-fault divorce in the United States?

California enacted the Family Law Act of 1969, signed by then-Governor Ronald Reagan, becoming the first U.S. state to drop fault as a requirement for divorce. ^[1] The law took effect January 1, 1970. Within a decade, most states followed.

By 1985, every state had some form of no-fault option. But several states required either fault grounds or a separation period of one to five years before no-fault grounds could be used, which effectively limited access. New York was the notable exception: until 2010, it allowed no-fault divorce only after a formal separation agreement had been in place for at least one year. If both spouses didn't agree to a separation agreement, fault grounds were the only path. ^[2]

New York's 2010 amendment to Domestic Relations Law Section 170 added "irretrievable breakdown" as a standalone ground, requiring only that a spouse state under oath that the marriage had broken down irretrievably for at least six months. That closed the last gap in U.S. divorce law.

The policy debates over no-fault law keep going. Some researchers argue no-fault reforms reduced domestic violence by letting trapped spouses leave more easily. Others have studied effects on divorce rates and children's outcomes. The data is genuinely mixed and contested. One widely cited study by economist Leora Friedberg (1998) estimated that no-fault laws accounted for about 17% of the rise in divorce rates between 1968 and 1988, though later researchers have disputed the direction and size of that effect. ^[9]

Do I need a lawyer for a no-fault divorce?

No. You have a right to represent yourself in civil court, including family court, in every state. Self-represented litigants in family law are common enough that most state court systems have built dedicated self-help centers just for them.

The California Courts self-help center, the Texas Law Help site, and their equivalents in nearly every other state provide blank forms, instructions, and in many cases interactive form-filling tools at no cost. ^[4][5] If you and your spouse agree on everything, the paperwork is genuinely manageable without a law degree.

A lawyer earns the fee when the case is contested, when there are substantial assets with complicated ownership histories, when a business needs valuation, or when one spouse holds far more financial knowledge or bargaining power than the other. In those situations, the cost of a divorce attorney is usually justified by the outcome.

For a straightforward uncontested no-fault divorce with no complex assets and no minor children, plenty of couples handle the process themselves. DivorceClear's $149 document packet is one way to get properly formatted, state-specific forms without doing the research yourself, which most people find saves several hours of frustrating document hunting.

One honest note. Even in an uncontested case, having a lawyer review your settlement agreement before you sign is a smart move if you have a pension, real estate equity, or any asset where the value isn't obvious. A one-hour consultation fee is much cheaper than unwinding a bad agreement later.

What about covenant marriage: is no-fault divorce still available?

Three states, Arizona, Arkansas, and Louisiana, offer covenant marriage as an option. Couples who choose covenant marriage when they wed agree to a stricter set of divorce rules: mandatory premarital counseling, a longer separation requirement (usually two years for no-fault), and limited fault grounds if they want to divorce sooner.

Here's the key word: choose. Covenant marriage is opt-in. If you and your spouse entered a standard civil marriage, even in Arizona, Arkansas, or Louisiana, no-fault divorce rules apply to you the same as everywhere else. Only couples who specifically declared a covenant marriage when they married (or converted to one later by mutual agreement) are bound by the stricter rules.

Covenant marriages are rare. Louisiana, which created the first covenant marriage law in 1997, has seen only about 1% to 2% of marrying couples pick the covenant option. ^[10] If you're unsure what type of marriage you entered, check your marriage certificate or the county records where you married.

Frequently asked questions

What does 'irreconcilable differences' mean legally?

It means the marriage has broken down and can't be saved, and neither spouse needs to explain why. Courts accept the statement at face value. No evidence, witnesses, or explanation of specific incidents is required. The California Family Code, which originated the term, treats irreconcilable differences as sufficient cause for divorce without any further finding of fault on either side.

Can I get a no-fault divorce if my spouse cheated?

Yes. Infidelity doesn't prevent you from using no-fault grounds, and in most states it won't change how property is divided. You simply cite irreconcilable differences and proceed. In a handful of states like Virginia, adultery can affect alimony eligibility for the cheating spouse, but it won't block the divorce itself and doesn't require you to allege fault if you'd rather not.

How is a no-fault divorce different from a legal separation?

A legal separation is a court-recognized status where spouses live apart and divide responsibilities without ending the marriage. The marriage still exists legally: neither person can remarry. No-fault divorce ends the marriage entirely. Some couples use legal separation as a transitional step, or for reasons like maintaining health insurance coverage, but it's a separate legal status and not required before filing for divorce in most states.

What if my spouse won't sign the divorce papers?

If your spouse refuses to sign, the divorce can still happen. After you file and properly serve them, they have a deadline (usually 20 to 30 days) to respond. If they don't respond, you request a default judgment. If they respond but contest terms, the case becomes contested and a judge decides the disputed issues. No-fault law means your spouse can't block the divorce by simply refusing to participate.

Does no-fault divorce mean the divorce is automatically uncontested?

No. No-fault describes the legal ground you cite, not whether the spouses agree. You can file a no-fault divorce where both spouses fight bitterly over assets, custody, and support. That's a contested no-fault divorce, and it can be expensive and slow. Uncontested means both parties agree on all terms. The two concepts are independent of each other.

How long do I have to be separated before filing a no-fault divorce?

It depends on your state. Many states have no separation requirement at all. North Carolina requires one year of separation. South Carolina also requires one year. New York's law requires you to state the breakdown has existed for at least six months. Nevada, Florida, Texas, California, and most others have no mandatory separation period before filing, though some have waiting periods after filing before the divorce is final.

Will a no-fault divorce affect my Social Security benefits?

Divorce itself doesn't eliminate Social Security spousal benefits if the marriage lasted at least 10 years. You may be eligible to claim up to 50% of your ex-spouse's benefit if yours is lower, as long as you're 62 or older and unmarried. The Social Security Administration's rules apply regardless of whether your divorce was fault-based or no-fault. The grounds used have no effect on this calculation.

Are there states where no-fault divorce is harder to get?

It's available everywhere, but access varies. States with long mandatory separation periods (North Carolina's one year, South Carolina's one year) make the timeline much longer. Covenant marriage states (Arizona, Arkansas, Louisiana) apply stricter rules to couples who chose that marriage type. High filing fees in some California and Florida counties can also be a practical barrier, though fee waivers are available for lower-income filers.

Does a no-fault divorce require going to court in person?

Usually not, for a truly uncontested case. Most states allow you to submit your final judgment paperwork by mail or electronically, and a judge signs it without either party appearing. Some states do require a brief final hearing even for uncontested cases. Check your local court's instructions or self-help center. If your case is contested on any issue, a hearing becomes much more likely.

Can I file for no-fault divorce online?

You can prepare and sometimes submit your divorce paperwork online, depending on your state. Several state courts have e-filing systems for family law cases. What you can't do online is complete the legal process without ultimately filing with your county court. Online document preparation services help you create the correct forms; you still have to file them with the clerk and pay the fee.

What happens to a prenuptial agreement in a no-fault divorce?

A valid prenuptial agreement generally remains enforceable regardless of which divorce grounds you use. No-fault grounds don't invalidate a prenup. Courts review prenups for procedural validity (voluntary signature, full disclosure, no unconscionability) and then apply them to divide property and set support. If your prenup has terms that depend on proving fault (some do), those provisions may become inapplicable when you file no-fault.

How does no-fault divorce affect child custody decisions?

Custody is decided on the best interests of the child standard, which has nothing to do with which divorce grounds you used. No-fault grounds don't help or hurt your custody position. Courts look at parenting capacity, each parent's relationship with the child, stability, and similar factors. Serious misconduct like abuse or neglect can still be raised in custody proceedings regardless of the divorce grounds used.

What's the difference between a contested and uncontested no-fault divorce in terms of cost?

Substantial. An uncontested no-fault divorce typically costs $300 to $700 total including filing fees and document preparation. A contested no-fault divorce, where spouses litigate property, custody, or support, commonly costs each spouse $5,000 to $30,000 or more in attorney fees depending on complexity and duration. The filing fee is the same either way; it's the attorney time that drives contested costs up.

Is a no-fault divorce final once the judge signs it?

Yes. Once the judge signs the final decree of divorce (also called a final judgment of dissolution in some states), the marriage is legally ended. Both spouses are free to remarry. The decree is a permanent court order. Some terms within it, particularly child custody and support, can be modified later if circumstances change substantially, but the divorce itself is not reversible.
