Grounds for Divorce in Tennessee: Fault, No-Fault, and Alimony

Tennessee recognizes 15 grounds for divorce: two no-fault options and 13 fault-based reasons. Which one you file under is not just paperwork. The ground can shape how a judge treats alimony, influence custody decisions, and change how long your case takes to finalize. The grounds for divorce in Tennessee break down into a short no-fault list that most couples use and a longer fault-based list that comes into play when one spouse’s conduct is part of the story.

Before You Can File: Residency and Waiting Period

You have to clear two thresholds before any ground matters. If the events behind your divorce happened while you lived in Tennessee, you can file as soon as you’re ready, provided you’re still a resident. If they happened elsewhere, you or your spouse must have lived in Tennessee for at least six months before filing. Military members and their spouses who have lived in the state for at least one year are presumed to be residents unless strong evidence points to a domicile elsewhere.¹

Then there’s the waiting period. Couples without unmarried children under 18 have to wait at least 60 days after filing for the divorce to be finalized. If minor children are involved, that minimum stretches to 90 days.² Filing fees vary by county and by whether children are involved, so call your local circuit court clerk for the current figure.

The Two No-Fault Grounds

Irreconcilable Differences

This is the most common path because neither spouse has to prove wrongdoing. Both agree the marriage is over.³ The catch is in that word “both.” If your spouse contests the divorce, this ground is closed to you and you’ll have to file under a fault-based option.

Agreement alone isn’t enough either. The court will not grant the divorce unless it finds that you’ve made adequate provision, in writing, for custody, child support if applicable, and property division. If the judge thinks the agreement is unfair or incomplete, the case gets continued until the gaps are filled.² Many couples stall at this step. Bringing a detailed settlement to court, not a rough sketch, saves real time.

Two-Year Separation

The second no-fault ground is available when spouses have lived in separate residences for at least two continuous years, have not lived together as a married couple during that time, and have no minor children together.³ Unlike irreconcilable differences, this one doesn’t require the other spouse to agree. One person can file after the two-year mark on their own. The minor-children restriction is absolute, though. Any shared child under 18 rules this option out.

Inappropriate Marital Conduct

Tennessee’s statute uses “inappropriate marital conduct” as a broad category for behavior that makes living together unsafe or unbearable. It’s actually two related grounds. The first covers conduct that makes cohabitation unsafe or improper: physical violence, serious verbal abuse, threats, and patterns of behavior that put a spouse’s physical or mental health at risk.³ One dramatic event isn’t required. A pattern of degrading or controlling behavior over time can be enough, and medical records, police reports, text messages, and witness accounts all serve as evidence.

The second covers conduct that makes a spouse’s situation so intolerable they are effectively forced to leave the home. This often involves psychological rather than physical harm: severe humiliation, isolation from family and friends, and persistent emotional cruelty. The line between the two is blurry enough that attorneys frequently plead both. Either can influence alimony and custody.

Adultery

Adultery is straightforward to understand but not always easy to prove. Courts lean heavily on circumstantial evidence: hotel records, phone records, texts, investigator testimony. You don’t need a confession or photographs, but the evidence has to be strong enough that a reasonable person would conclude the affair happened. Vague suspicion won’t carry the day.

Where adultery hits hardest is financially. Tennessee courts can weigh the unfaithful spouse’s conduct when setting alimony, and an affair that involved spending marital money adds another layer. The property division statute identifies dissipation, meaning wasteful spending contrary to the marriage that reduces the marital estate, as a factor courts consider.⁴ Gifts, trips, and apartment payments for an affair partner are textbook examples. Documented through bank and credit card records, that spending lets the court adjust the division of what’s left.

Abandonment and Desertion

Tennessee actually recognizes three separate abandonment-related grounds.

Desertion for one year. One spouse left without reasonable cause and stayed away for a full year. The departure has to be deliberate, not driven by a safety concern or military deployment.
Abandonment with failure to provide. One spouse either left or forced the other out of the home without justification and then refused or neglected to provide financial support despite being able to. There is no minimum time requirement here; the combination of departure and financial cutoff is what matters.
Refusal to move to Tennessee. If one spouse lives in Tennessee and the other refuses to join them without reasonable cause and remains absent for two years, that’s a separate ground.

A temporary separation, a spouse leaving because of domestic violence, or a departure driven by work or a family emergency usually won’t meet the bar. Courts look at intent and circumstances, not just absence.

Habitual Substance Abuse

Tennessee permits divorce for habitual drunkenness or drug abuse, but the statute has a timing rule that catches people off guard: the habit has to have started after the marriage. If your spouse had a substance abuse problem before you married and you knew about it, this ground doesn’t apply. You’d need to file under something else, such as inappropriate marital conduct, if the addiction produced abusive or dangerous behavior.

When substance abuse does qualify, it often shows up in custody rulings. Judges focus on the child’s best interests, and a parent with an active addiction may face supervised visitation, drug testing requirements, or limits on overnight parenting. Medical records, arrest reports, and financial records showing heavy spending on drugs or alcohol all help establish the ground.

Criminal Conviction

There are two crime-related grounds, and the distinction matters:

Felony with prison time. Conviction of a felony with a sentence to confinement in a state penitentiary. A felony conviction that results in probation rather than imprisonment may not satisfy this ground.
Infamous crime. A separate ground for conviction of any crime that renders a person “infamous” under Tennessee law. This overlaps with felonies in many cases but can capture certain offenses that don’t result in penitentiary time.

Convictions involving violence also weigh heavily in custody decisions. If the incarcerated spouse can’t attend court proceedings, the court may proceed without them.

The Narrower Fault Grounds

Four remaining grounds come up less often but are on the books:

Attempting to kill the other spouse by poisoning or any other method showing intent.
Bigamy. The other spouse was already married to someone else at the time of your marriage.
Impotence at the time of marriage that is permanent and continues.
Pregnancy by another person. The wife was pregnant by someone else at the time of marriage and the husband did not know.

Narrow as they are, when they apply the divorce becomes relatively simple to prove.

How Fault Affects Alimony

This is the practical reason most people care which ground they file under. Tennessee courts consider a list of factors in deciding whether to award alimony, how much, and for how long. One of those factors is the relative fault of the parties, and the court has discretion to weigh it as heavily or lightly as it sees fit.⁵ Adultery does not automatically disqualify a spouse from receiving support, but it can tip the scales, especially when the unfaithful spouse is the higher earner or when the affair caused financial harm.

Fault cuts both ways. A spouse who was abusive, abandoned the family, or drained the finances through addiction may find the court less sympathetic to a request for support. A spouse on the receiving end of that conduct is in a stronger position to ask for it.

How Fault Affects Property Division

Property division works differently, and this surprises many people. Tennessee divides marital property equitably, and the statute is explicit that fault is not a factor in that division.⁴ A cheating spouse does not automatically get a smaller share of the house or retirement accounts.

The exception, again, is dissipation. Courts weigh each spouse’s contribution to the marital estate, including whether one spouse wasted assets through spending contrary to the marriage. Money spent on an affair, gambling losses, or reckless purchases during the marriage’s breakdown can all qualify. If you can document the waste, the court can adjust the division to compensate. This is not a punishment. It’s an accounting correction, so the court divides what should have been there rather than only what remains.
