To file for legal separation in Tennessee, you file a Complaint for Legal Separation in the circuit or chancery court of the county where you or your spouse lives, state your grounds, serve your spouse under the Rules of Civil Procedure, and — if you’re using irreconcilable differences — wait out a 60-day or 90-day statutory period before the court enters a final decree. The marriage stays intact throughout; the court can still divide property, order support, and set custody.1Justia. Tennessee Code 36-4-102 – Legal Separation
Confirm You Meet the Residency Requirement
At least one spouse must have lived in Tennessee for six months before filing. The residency statute is written for divorce, but because legal separation uses the same grounds framework and is filed as an alternative to a divorce complaint, courts apply the same jurisdictional rule.2Justia. Tennessee Code 36-4-104 – Residence Requirements If the conduct behind the separation happened entirely outside Tennessee and is not ongoing, the six-month clock is what gives a Tennessee court the power to hear the case at all.

Choose Your Grounds
Your complaint has to state grounds using the same language as a divorce complaint.1Justia. Tennessee Code 36-4-102 – Legal Separation Most people use irreconcilable differences, the no-fault option. It has two conditions: both spouses have to agree to it, and the court has to approve a written agreement resolving every disputed issue. If your spouse won’t cooperate, or if you can’t reach agreement on custody, support, and property, this ground isn’t available.
The fault-based grounds only one spouse has to assert, but you have to prove them. They include adultery, abandonment for at least one year, inappropriate marital conduct (a broad category covering cruelty and mistreatment), habitual drug or alcohol abuse that developed after the marriage, felony conviction with a prison sentence, and attempted murder. The spouse making the accusation carries the burden of proof, which is why fault cases take longer and cost more.
Prepare and File the Complaint
The case starts with a Complaint for Legal Separation filed in the circuit or chancery court of the county where you or your spouse lives. The complaint identifies both spouses, states the grounds, and asks for specific relief: custody, support, property division, or a combination. You file a Summons with it — the formal notice that a case has been opened.
Depending on your situation, you’ll usually file some or all of these alongside the complaint:
- A Parenting Plan, required when minor children are involved, covering physical custody schedules, decision-making authority, holidays and vacations, and each parent’s financial responsibilities.
- A Marital Dissolution Agreement or Property Settlement Agreement if you and your spouse agree on how to divide assets, debts, and support. This is the document the court needs to approve if you’re proceeding on irreconcilable differences.
- A Child Support Worksheet, which calculates each parent’s obligation under the Tennessee Child Support Guidelines.
Filing fees vary by county and typically fall between roughly $230 and $310, with cases involving minor children costing more. If you can’t afford the fee, submit a Request to Postpone Filing Fees; the form asks you to declare your finances under penalty of perjury, and a judge decides whether to waive.3Tennessee Courts. Request to Postpone Filing Fees and Order (Form 3)
Serve Your Spouse
Your spouse has to receive formal notice of the case before it can move forward. Tennessee’s Rules of Civil Procedure give you several options. You can send the complaint and a certified copy of the summons by registered or certified mail with return receipt, and the plaintiff or the plaintiff’s attorney can handle the mail service directly.4Tennessee Administrative Office of the Courts. Rule 4.04 – Service Upon Defendants within the State For in-person service, a sheriff or private process server does it. You cannot hand the papers to your spouse yourself.
If your spouse refuses to sign for certified mail, that refusal is noted on the return receipt and filed with the court, where it counts as valid service.4Tennessee Administrative Office of the Courts. Rule 4.04 – Service Upon Defendants within the State Proof of service, whether the postal return receipt or a Return of Service completed by the sheriff or process server, has to be on file before the case can proceed.
Wait Out the Statutory Period
If you’re using irreconcilable differences, Tennessee imposes a mandatory waiting period before the court can finalize the case. It’s 60 days for couples without minor children and 90 days for couples with minor children, counted from the date of filing. Agreement between the spouses can’t shorten it. Fault-based cases don’t have a specific statutory waiting period, but they generally take longer because of the evidence and hearings involved.
Attempt Mediation If the Court Orders It
Tennessee courts can order mediation before trial, and many judges do. A neutral mediator works with both spouses on custody, property, and support. Skipping court-ordered mediation without good reason can put you in contempt.5Tennessee Administrative Office of the Courts. Mediation Questions
Court-ordered mediation has to wrap up and report results within 180 days of the filing date. An agreement reached in mediation gets folded into the court’s final orders. If mediation fails, the case goes to trial. Sessions can happen by video where appropriate. Mediator fees typically run $100 to $300 per hour, and some courts keep lists of approved mediators offering sliding-scale rates based on income.6Tennessee Administrative Office of the Courts.

Get to the Final Hearing
Uncontested cases move quickly. The court reviews your written agreements, confirms they’re fair and adequate — especially anything involving children — and enters final orders. The hearing itself is usually brief. This is the natural path when you’ve filed on irreconcilable differences, because that ground requires a signed settlement agreement anyway.
Contested cases look like a trial. Each side presents evidence, calls witnesses, and argues on disputed issues. The judge decides anything you couldn’t resolve. Temporary orders can handle urgent matters while the case is pending — who pays the mortgage, where the children live — and stay in effect until the final decree.
What the Decree Can Cover
The decree can address the same categories a divorce would.
Custody follows the best-interests-of-the-child standard, weighing each parent’s relationship with the child, the stability of each home, each parent’s willingness to encourage a relationship with the other parent, and the child’s own preference if old enough to express one. Courts can award joint or sole custody with visitation.
Child support runs off the Tennessee Child Support Guidelines, a formula built on each parent’s gross income, overnights with each parent, health insurance costs for the children, and work-related childcare. The guidelines produce a presumptive number; judges rarely deviate without a specific reason. Modifications later require a “significant variance,” meaning at least a 15% difference between the current support and what the guidelines would now produce.7Legal Information Institute. Tennessee Comp. R. and Regs. 1240-02-04-.05 – Significant Variance
Alimony comes in four forms — rehabilitative, transitional, alimony in futuro, and alimony in solido — and the court can order one or a combination. It weighs the length of the marriage, each spouse’s earning capacity and financial resources, contributions to the marriage including homemaking, and the standard of living during the marriage.8Justia. Tennessee Code 36-5-121 – Decree for Support of Spouse
Property and debt divide under equitable distribution, which means fairly rather than automatically equally. The court classifies each asset and debt as marital or separate, then divides the marital portion based on factors like the length of the marriage, each spouse’s economic circumstances, and each spouse’s contributions to acquiring and preserving marital property.9Justia. Tennessee Code 36-4-121 – Division, Distribution, or Assignment of Marital Property
Fix What the Decree Can’t Fix
Two categories of problem the separation order does not solve on its own, so build them into your filing plan.
Joint debts. The court can assign a marital debt to your spouse, but that ruling only binds the two of you. It does not change your contract with the creditor. If both names are on a credit card or mortgage and your spouse stops paying, the creditor can still come after you, and your credit takes the hit. Your remedy is enforcement in court, which doesn’t undo the damage. Close joint accounts and refinance joint debts into individual names wherever you can.
Estate plan and beneficiaries. Legal separation does not dissolve the marriage, so your spouse keeps the inheritance rights of a married person. If you die without a will, your separated spouse inherits under Tennessee’s intestate succession rules. If your existing will names your spouse as beneficiary, that designation stands. Divorce automatically revokes a former spouse’s inheritance rights in most situations; separation changes nothing. If you don’t want your separated spouse to inherit, you have to update your will, change beneficiary designations on life insurance and retirement accounts, and review any powers of attorney or healthcare directives naming your spouse.
Converting a Legal Separation to Divorce Later
Tennessee law explicitly preserves the right of either spouse to seek a full divorce after a separation.1Justia. Tennessee Code 36-4-102 – Legal Separation Either party can file a new divorce complaint. The existing orders on custody, support, and property typically stay in effect until the divorce court modifies or replaces them. There’s no mandatory waiting period between the legal separation and a subsequent divorce filing, but you do have to establish separate grounds for the divorce complaint.
