When one spouse files for divorce, that spouse is the plaintiff (also called the petitioner), and the other spouse, who receives the papers and must respond, is the defendant (also called the respondent). The labels are assigned purely by who acts first. Neither label gives a legal edge on custody, property division, or support, though filing first does carry a few practical advantages worth understanding.
What the Filing Spouse Does
The spouse who starts the case prepares and submits a document to the local court, usually called a petition for dissolution of marriage or a complaint for divorce, depending on the state. The petition identifies both spouses, states the grounds for divorce, and lays out what the filing spouse is asking for: a proposed custody arrangement, a division of property and debts, and any request for spousal support.
Filing the petition officially opens the case and establishes which court has authority over the divorce. The filing spouse is then responsible for delivering copies of the petition and a court summons to the other spouse through a legally recognized method called service of process. The filing spouse cannot hand-deliver the papers personally. Most states allow service through a professional process server, a sheriff’s deputy, another adult who is not a party to the case, or certified mail with a return receipt. When a spouse cannot be located after reasonable effort, courts may allow service by publication, meaning a notice is printed in a local newspaper for a set period.
What the Receiving Spouse Does
Once served, the other spouse becomes the respondent or defendant and has a limited window to file a written answer with the court. Response deadlines vary by state but typically fall between 20 and 30 days after personal service within the state. Service by mail or service on a spouse in a different state often triggers a longer deadline, sometimes 60 or even 90 days.
The answer lets the respondent agree with some or all of the petition’s requests, dispute specific claims, or raise new issues the petitioner left out. Reading the petition carefully matters here. Any request the respondent doesn’t contest can be treated as uncontested, and anything the respondent wants that isn’t in the petition won’t be addressed unless the respondent raises it.
Why Ignoring the Papers Is a Serious Mistake
When a respondent fails to file an answer by the deadline, the petitioner can ask the court for a default judgment. A default essentially means the court treats the respondent’s silence as agreement. The judge can then grant the divorce on the terms laid out in the original petition without the respondent’s input. The petitioner generally cannot receive anything beyond what they specifically requested in the petition, so courts won’t improvise extra relief. But the respondent loses the ability to contest custody, support, property division, or anything else.
Undoing a default judgment is possible but difficult. The respondent typically must show a valid reason for missing the deadline, such as never actually receiving the papers or a serious medical emergency, and courts are not generous with excuses. Responding on time, even if only to ask for more time, is always better than staying silent.
Filing a Counterclaim
Along with the answer, the respondent can file a counterclaim, sometimes called a counter-petition. A counterclaim is the respondent’s chance to make their own requests rather than only reacting to the petitioner’s proposals. If the petitioner asked for primary custody, for example, the respondent’s counterclaim can request a different custody arrangement, spousal support, or a different split of marital property. Without a counterclaim, the case moves forward based only on what the petitioner asked for, and the respondent is left playing defense on someone else’s terms.
A counterclaim also prevents the petitioner from walking away from the case. The petitioner can generally dismiss their own petition before trial, but if the respondent has filed a counterclaim, that counterclaim stands as an independent request for divorce and must be resolved on its own.
Does It Matter Who Files First?
Filing first doesn’t give you a legal advantage on the issues that matter most. Courts decide custody, support, and property division based on the facts of the case, not on who submitted paperwork first. That said, there are a few practical benefits to being the petitioner that can shape how the process unfolds.
- Choice of venue. When spouses live in different counties or different states, the petitioner picks where to file, assuming they meet residency requirements. That choice can determine which state’s laws apply, how far each party has to travel for hearings, and whether key witnesses are nearby. If both spouses meet residency requirements in different states, it becomes a race to file first.
- Preparation time. The petitioner controls the timeline leading up to filing, which means time to organize financial records, consult an attorney, and plan logistics before the other spouse even knows the case exists. The respondent is reacting under a deadline.
- Temporary orders at filing. The petitioner can request temporary court orders at the same time they file the petition. These orders can address custody, child support, spousal support, and restrictions on selling marital assets or running up joint debt while the case is pending. The respondent can request the same orders, but only after being served and filing an answer, which builds in a delay.
- Presentation order at trial. If the case goes to trial, the petitioner typically presents their evidence and witnesses first. This isn’t decisive, but framing the issues before the other side responds can influence how the judge perceives the case from the start.
None of these advantages change the legal standard a judge applies. In practice, preparation and positioning matter, especially in high-conflict divorces or cases that cross state lines.
Plaintiff or Petitioner, Defendant or Respondent
Some states call the filing spouse the petitioner and the other the respondent. Others use plaintiff and defendant. A few states use one set of terms for no-fault cases and the other for fault-based filings. The labels are interchangeable in meaning: one spouse starts the case, the other responds.
No court treats a defendant in a divorce the way it treats a defendant in a criminal case. The word carries no stigma, no presumption of wrongdoing, and no procedural disadvantage. If your paperwork says respondent where you expected defendant, or vice versa, you’re looking at a difference in local convention, not a difference in your legal rights.
