How attorneys use private detectives in Tennessee litigation
The best litigators treat a licensed private detective as part of the trial team: fact-finding that discovery cannot reach, delivered in a form the court will accept.
Family law
- Infidelity and cohabitation surveillance for fault, alimony and modification.
- Custody conduct documentation tied to the § 36-6-106 factors.
- Asset searches that target discovery requests and subpoenas.
- Identification and background on third parties in the child’s life.
- Service of process on evasive spouses.
Criminal defense
- Independent witness locating and recorded or written statements.
- Scene documentation: sight lines, lighting, distances, cameras in the area.
- Alibi verification through records, video and witnesses.
- Canvassing for witnesses law enforcement did not find.
- Post-conviction investigation and record review.

Engagement checklist for firms
What experienced litigators send with the first call, so the work starts the same day:
- The case caption, court and any scheduled dates.
- The question to be answered, in one sentence, and the theory it supports.
- Everything already known: names, addresses, vehicles, photographs, prior private detectives’ work.
- Discovery that bears on the task: police reports, depositions, the other side’s disclosures.
- Who the private detective reports to and how (secure email, portal, hard copy).
- Budget authority and the decision points at which counsel wants to be consulted.
- Whether testimony is anticipated and in which court.
With that in hand, a locate or records pass usually starts within hours and surveillance is staged within a day or two in Middle Tennessee.
Illustrative engagements
Family law
Counsel suspects the opposing spouse is cohabiting. A three-week cohabitation engagement produces a dated table of overnights, domestic routine on video and a registration tying the partner to the address. The petition to modify alimony attaches the summary; the private detective testifies at the hearing.
Criminal defense
The discovery identifies a witness by first name and street. The private detective locates the witness, takes a recorded statement contradicting the officer’s account of lighting and distance, documents the scene at the same hour, and canvasses for a camera the police missed. Counsel uses all three at the suppression hearing.
Insurance defense
A claimant with a lifting restriction operates a landscaping side business. Three sessions document it; the carrier’s counsel uses the footage at mediation and the claim resolves.
Collections
A judgment debtor claims no assets. The asset search finds a Wilson County lot, a boat and employment in Franklin; counsel records the lien and garnishes wages.
What experienced counsel avoids
- Vague assignments (“see what you can find”). Scope produces evidence; curiosity produces invoices.
- Unlicensed operators whose work cannot be defended on cross.
- Letting the client run their own parallel surveillance.
- Waiting until the week before trial to locate witnesses.
- Over-investigating: evidence beyond what the case needs costs money and can look vindictive to a judge.
Billing and budget control for firms
Firms get engagement letters with rates, minimums and expense categories; itemized statements by matter; and decision points written into the scope so that no work proceeds beyond the authorized phase without a call. Testimony, preparation and travel are billed as time. For recurring work we offer account terms and monthly statements. Clear budgets keep investigations proportionate, which judges notice and clients appreciate.

The private detective as part of the trial team
Firms that get the most from investigative work bring the private detective into the case early, share the theory and the discovery, define the question and let the agency propose the method. They treat the report as a working document, not a surprise, and they schedule testimony as soon as hearing dates are set. The result is evidence that fits the case, costs that stay proportionate and a witness who is prepared.
Firms that get the least send a vague assignment late, receive a file they did not shape, and discover at the hearing that the vantage point or the identification will not hold. The difference is not the agency; it is the engagement. Pinnacle’s intake for attorneys is built around the first pattern, and our engagement letters are written to support it.
A criminal defense case, in detail
A client charged with aggravated assault outside a Lower Broadway bar said he acted in self-defense and that a bystander saw the other man swing first. The police report listed the bystander only as ‘Marcus, works nearby.’ Within two days the private detective identified him through a canvass of businesses on the block, located his apartment in Antioch, and took a recorded statement that matched the client’s account. The private detective also photographed the scene at the same hour, documenting the lighting and a camera on a neighboring building; a preservation request produced footage before it was overwritten. Counsel used the statement, the photographs and the footage at a preliminary hearing. The charge was reduced. The total engagement was under a week.
Engagement structure and work product
Counsel typically retains the agency directly so the private detective works at the attorney’s direction in anticipation of litigation. The scope of any work-product protection is counsel’s call; our practice is to report to counsel, preserve originals, keep same-day logs and make named private detectives available for deposition and trial. Testimony terms and rates are in the engagement letter. See our attorney page and how testimony works.
