Tennessee divorce grounds, and when evidence matters
Many Tennessee divorces end in an agreement and never require proof of anything. Others become contested, and then facts matter. Here is how the grounds work, and where investigation fits.

- Tennessee allows divorce on irreconcilable differences or on fault grounds such as adultery.
- An agreed divorce requires a marital dissolution agreement and a waiting period: 60 days without minor children, 90 days with them.
- Evidence of fault can affect negotiations and alimony even when it doesn’t decide the divorce itself.
Fault and no-fault grounds
Tennessee lists the grounds for divorce, including irreconcilable differences and fault grounds such as adultery, cruel and inhuman treatment, abandonment, and habitual drunkenness or drug abuse. A divorce can also be granted after a period of separation in certain circumstances.
Irreconcilable differences works best when both spouses agree on everything. If they can’t, the case may proceed on fault grounds.
Waiting periods
For an irreconcilable-differences divorce, Tennessee requires the complaint to be on file at least 60 days before a final hearing if there are no minor children, and 90 days if there are. Contested cases take longer.
When evidence of fault matters
- When one spouse refuses to agree, and fault becomes the ground
- In alimony decisions, where courts may consider the relative fault of the parties
- In property division, where money spent on an affair can be raised as dissipation
- In custody, where conduct affecting the child matters (see custody evidence)
- In negotiation, where strong documentation changes the other side’s calculations
Who to talk to first
Usually an attorney, so the investigation is aimed at what your case actually needs. Some clients come to us first because they need to know the truth before they decide whether to divorce at all. Either order works; read lawyer or detective first?
