To get a legal separation, you file a petition with the family court, superior court, or circuit court (the name depends on your state) in the county where you or your spouse meet the residency requirement. Before you prepare anything, confirm two things: that your state actually recognizes legal separation, and that you meet both the state and county residency periods for the court you plan to use. Where to file a legal separation turns almost entirely on those two questions.
States That Do Not Recognize Legal Separation
Roughly ten states do not offer legal separation as a formal court proceeding. If you live in Delaware, Florida, Georgia, Maryland, Massachusetts, Michigan, Mississippi, Pennsylvania, South Carolina, or Texas, you cannot file a petition for legal separation in the traditional sense. Filing in one of these states without realizing this can cost months and hundreds of dollars in court fees.
Several of these states offer something that does similar work. Georgia, Massachusetts, Michigan, Mississippi, and South Carolina allow what is sometimes called separate maintenance, in which a court can issue orders covering child support, spousal support, and custody while the marriage remains intact. Maryland uses a process called limited divorce that serves a similar function. In Florida, Texas, Pennsylvania, and Delaware, couples can separate physically and sign private agreements, but no court will issue a formal separation decree. If you live in one of those states and want court-enforceable orders without divorcing, search for your state’s specific alternative rather than following general legal separation steps.
Residency and Jurisdiction
Every state that allows legal separation requires at least one spouse to have lived in the state for a minimum period before filing. That period ranges from as little as six weeks to a full year, with six months being the most common. Many states add a second layer: you also must have lived in the specific county where you file for a shorter period, often 90 days. These rules exist to prevent people from shopping for favorable laws by filing somewhere they do not actually live.
The court where you file needs authority over your marriage, and ideally over both spouses and any property at issue. When spouses live in different states, you can usually file in whichever state at least one of you meets the residency requirement. But a court in one state may have limited power to divide property located in another state or to order an out-of-state spouse to pay support. If you and your spouse live apart in different states, talking to an attorney about jurisdiction before you file can save real problems later.
Which County
Within a qualifying state, you file in the county where you meet the local residency requirement. In some states these cases go to family court; in others they go to circuit or superior court. If you are not sure which courthouse handles separations, call the clerk’s office in your county and ask directly.
Military Families
Active-duty service members get special residency treatment. Under the Servicemembers Civil Relief Act, a service member does not lose or gain a state of residence simply because military orders stationed them somewhere new.1Office of the Law Revision Counsel. 50 USC 4001 – Residence for Tax Purposes A soldier stationed in North Carolina for three years can still claim residency in the state they consider home. Military spouses who relocated solely to live with the service member may also keep their original state residency. Military couples often have a choice between the state where they are stationed and the state they call home, but they need to meet the residency period for whichever state they pick.
When Children Are Involved
If your case involves child custody, jurisdiction follows the child, not the parents. Under the Uniform Child Custody Jurisdiction and Enforcement Act, which nearly every state has adopted, the state where the child has lived with a parent for at least six consecutive months immediately before filing is the child’s home state. That state has primary jurisdiction over custody. If you recently moved with your children, you may need to file in the state you left rather than the state where you now live, depending on how long you have been in the new location. Getting this wrong can produce a custody order that a court later refuses to enforce.
Preparing Your Petition and Supporting Documents
The central document is a petition for legal separation. Some states call it a complaint. The petition asks for basic information: full legal names and addresses for both spouses, the date and place of your marriage, and the names and birthdates of any minor children. It also asks what you want from the court, such as a custody arrangement, child support, spousal support, or a division of property and debts.
Most courts require additional forms alongside the petition, including a summons (the document that formally notifies your spouse) and, in many jurisdictions, preliminary financial disclosure forms. The correct forms are usually on your state’s judicial council website, the specific court’s website, or at the county court clerk’s office. Fill them out carefully. Errors or missing information can delay your case or force you to refile.
Financial Disclosures
Most states require both spouses to exchange detailed financial information early in the case. You will typically need to list everything you own, everything you owe, your income, and your monthly expenses, with supporting documents like recent tax returns, pay stubs, and bank statements. This exchange is mandatory. Hiding assets or underreporting income can lead to serious consequences: courts can award a larger share of property to the other spouse, impose financial penalties, or order the dishonest spouse to pay the other side’s attorney fees.
Filing the Petition With the Clerk
Once your forms are complete, file them with the clerk of court in the county where you meet the residency requirement. Most courts accept filings in person at the courthouse, by mail, or through an electronic filing portal.
Expect to pay a filing fee that varies widely by state and county. Fees in many jurisdictions fall between $200 and $400, though some are lower and a few are higher. Payment methods typically include cash, check, money order, or credit card. If you cannot afford the fee, you can ask the court for a fee waiver. Eligibility usually depends on your income relative to the federal poverty guidelines, and the clerk’s office can provide the application. You will need to attach proof of your income or public assistance.
Bring the original petition plus at least two copies: one for your records and one that will go to your spouse. After the clerk accepts your filing, they will stamp the documents with the filing date, assign a case number, and return your copies. That case number goes on every document you file for the rest of the case.
Serving Your Spouse
Filing the petition does not notify your spouse. You are responsible for formally delivering the documents through a process called service of process. Without proper service, the court cannot proceed, because it lacks jurisdiction over your spouse.
Common Service Methods
The most reliable method is personal service, where someone physically hands the documents to your spouse. This is typically done by a county sheriff, a professional process server, or any adult who is not a party to the case. Professional process servers generally charge between $40 and $200 depending on location and difficulty. Some states also allow service by certified mail with a return receipt requested, which produces a signed record that your spouse received the documents. Check your state’s rules, because not every state accepts certified mail for the initial petition.
When Your Spouse Agrees to Accept the Papers
If your spouse is cooperative, many states allow them to sign a voluntary waiver or acceptance of service. Your spouse signs a form acknowledging receipt of the petition, which you then file with the court. A waiver does not mean your spouse agrees with what the petition asks for; it only means they acknowledge receiving it. Your spouse keeps every right to contest the case, challenge jurisdiction, or file their own requests.
When You Cannot Find Your Spouse
If you genuinely cannot locate your spouse after making diligent efforts, some courts allow service by publication, which involves publishing a notice in a local newspaper for a set number of weeks. Courts treat this as a last resort and will require you to document what you did to try to find your spouse before approving it. Service by publication often limits what the court can order, particularly on property division and support.
Filing Proof of Service
No matter which method you use, you must file a proof of service form with the court confirming that your spouse received the documents. This form identifies who served the papers, when, where, and how. Without it on file, your case stalls. If there is an error on the proof of service, the person who served the documents will need to complete a corrected version.
