An original petition for divorce is the document that formally opens a divorce case. The spouse who files it (the petitioner) submits it to a family court in a county where residency requirements are met, and it tells the court who the parties are, why the marriage should end, and what the petitioner is asking for regarding property, debts, support, and any children. Every hearing, order, and negotiation that follows builds on what this petition says, so the details matter.
What Goes in the Petition
The petition identifies both spouses by their full legal names and current addresses. It states the date and location of the marriage, whether there are minor children, and where those children currently live. If children are involved, it lists their names, dates of birth, and living arrangements, because those details drive custody and support decisions later.
The petition also has to show the court has authority to hear the case. Every state sets its own residency threshold. Some require only that you be a resident on the day you file; others require up to two continuous years. A large number of states land in the six-month range, and some add a minimum period of residency in the specific county where you file. Filing in the wrong jurisdiction can get your case dismissed, so confirming you meet your state’s rule is one of the first things to check.
Finally, the petition states the legal grounds for the divorce and lays out what the petitioner wants: a proposed division of property and debts, spousal support, custody, and child support. These are opening positions, not final orders. Your spouse will get a chance to agree, disagree, or propose something different.
Choosing Grounds: No-Fault or Fault
All 50 states allow no-fault divorce, where you state that the marriage is irretrievably broken or that there are irreconcilable differences. You don’t have to prove anyone did anything wrong. This is the most common approach and tends to make the process faster and less adversarial.
About two-thirds of states also still recognize fault-based grounds such as adultery, abandonment, cruelty, or substance abuse. Choosing fault raises the stakes. You’ll need to prove the misconduct, which means more evidence, more court time, and higher legal costs. The potential upside is that some states let judges weigh fault when dividing property, setting alimony, or deciding custody. A spouse who committed adultery, for example, might receive a smaller share of marital assets. That trade-off isn’t guaranteed, and the added conflict can make settlement harder. Most divorce attorneys recommend no-fault grounds unless the fault genuinely affects a financial or custody outcome in your state.
Where and How to File
You file the petition with the clerk of the family court in the county where you (or sometimes your spouse) meet the residency requirement. The clerk assigns a case number that will track every document and hearing from that point on, and gives you a file-stamped copy as proof the case is open.
Filing fees generally run from about $100 to $400, depending on the state and county. If you can’t afford the fee, most courts let you apply for a waiver. You’ll usually fill out a financial affidavit showing your income and assets fall below a set threshold, often tied to the federal poverty level. If the court grants the waiver, you proceed without paying upfront.
Many courts now require or strongly encourage electronic filing through an online portal instead of walking paper documents to the clerk’s office. Where e-filing is mandatory, paper submissions may be rejected. Check your local court’s website before you go, because the rules vary significantly even between counties in the same state.
When you file, the court also issues a summons. This is a one-page document that identifies the court, lists both parties, gives the case number, and tells your spouse how long they have to respond and what happens if they don’t. The summons and the petition travel together and must be delivered together.
Serving Your Spouse
Filing gets the case on the docket, but the case can’t move forward until your spouse is formally served with copies of the summons and petition. This step, called service of process, is what gives the court authority over the respondent. You can’t hand the papers to your spouse yourself; service has to be performed by a neutral third party.
The most common methods are personal delivery by a sheriff’s deputy or a professional process server, and certified mail with a return receipt. Hiring a process server usually costs between $40 and $100 for a straightforward local delivery. Some states also allow service by a private adult who isn’t a party to the case, provided they file a proof of service afterward showing when and how the documents were delivered.
If you genuinely cannot locate your spouse after reasonable efforts, most courts allow service by publication. This means publishing a legal notice in a newspaper for a set period, typically once a week for three consecutive weeks. You’ll file a motion explaining what steps you took to find your spouse and why those efforts failed. A judge reviews the motion and, if satisfied, grants permission. Publication is a last resort, and courts look closely at whether you actually tried to locate the person before approving it.
What Kicks In the Moment You File
Automatic Restraining Orders
In a number of states, filing a divorce petition triggers automatic temporary restraining orders that apply to both spouses immediately. They’re designed to freeze the financial status quo so neither side can drain accounts, cancel insurance, hide assets, or take the children out of state while the case is pending. You don’t have to request them separately; they’re printed on the summons or attached to it. Violating them can bring contempt-of-court sanctions, so read every page of your summons.
Waiting Periods
Most states impose a mandatory waiting period between the filing date and the earliest date a divorce can be finalized. The clock typically starts when the petition is filed or when the respondent is served. Waiting periods range from as short as 20 days to as long as six months, with 30 to 90 days being the most common window. Roughly a dozen states have no waiting period at all, though the practical timeline for paperwork, financial exchange, and getting a court date usually still runs at least a few months.
Temporary Orders
If you need immediate decisions about who stays in the family home, who has custody, or whether either spouse pays support while the case is pending, you can ask the court for temporary orders. Some courts let you file for these at the same time as the petition. A judge holds a short hearing, sometimes only a few minutes long, and issues orders that stay in place until the divorce is finalized or the court modifies them. Temporary orders aren’t a preview of the final outcome, but they set the ground rules both spouses live under during the case. If you and your spouse can agree on these issues, you can submit a written agreement to the court instead of going through a hearing.
What Your Spouse Can Do in Response
After being served, the respondent has a limited window to file a formal response, called an answer. Deadlines vary by state but typically fall between 20 and 30 days from the date of service. The answer lets the respondent agree or disagree with each claim in the petition and state their own position on property, custody, and support.
The respondent can also file a counter-petition alongside the answer. A counter-petition is the respondent’s own set of requests. It might propose a different custody arrangement, ask for spousal support the original petition didn’t mention, or cite different grounds. Filing one also protects the respondent if the petitioner later tries to dismiss the case; once a counter-petition is on file, the divorce can proceed even without the petitioner’s cooperation.
Ignoring a divorce petition is one of the most expensive mistakes a respondent can make. Once the deadline passes without an answer, the petitioner can ask the court to enter a default, then submit a proposed judgment covering property division, custody, support, and debts. If it appears fair and meets legal requirements, the court can approve it as the final decree, and the respondent has no say in any of it. Overturning a default later is difficult and requires a compelling reason, such as never actually receiving the papers or a serious emergency. Filing an answer on time is the single most important thing a respondent can do.
Amending the Petition Later
Divorce cases can last months or even years, and circumstances change. You might discover assets you didn’t know about, a child’s needs might shift, or your income might change. Amending the petition lets you update your claims and requests.
Early in the case, before the respondent has filed an answer, most courts allow amendments without much fuss. After an answer is on file, you’ll generally need to file a motion explaining why the changes are necessary and get the court’s approval. Once amended, the petition has to be served again, and the respondent gets time to respond to the new claims. Courts usually grant amendments as long as they don’t unfairly prejudice the other side or cause unreasonable delay.
One practical point: if you already know your financial picture is complicated or that custody is likely to be contested, put extra time into the original petition. Amendments are allowed, but each one adds cost and delay. A thorough petition at the start means fewer surprises later.
