What Defense Attorneys Should Know Before Hiring a Private Investigator

Defense attorneys and private investigators need each other, but the relationship doesn’t always work the way it should. Attorneys who have had bad experiences with PIs — missed deadlines, sloppy documentation, an investigator who couldn’t testify coherently — sometimes write off the resource entirely. That’s a mistake. The problem usually isn’t the concept; it’s a mismatch between what the attorney needed and what they got.

Here’s what actually matters when you’re evaluating whether to bring a PI into a case, and what to look for when you do.

Licensing Isn’t Optional — It’s the Floor

In Georgia and Alabama, private investigators are required to be licensed. This isn’t just a technicality. If evidence is gathered by an unlicensed investigator, it can be challenged — and depending on the judge, it can be excluded. Before you hand anything off, confirm that the person is licensed in the state where the work will be conducted. At 3rd Eye, we hold active licenses in both states, and we only work within those boundaries.

Beyond licensing, ask about professional affiliations. Membership in organizations like the Georgia Association of Professional Private Investigators or the World Association of Detectives signals that an investigator takes the profession seriously and stays current with industry standards.

Bring Us In Early

The most common mistake defense attorneys make is waiting too long. PIs get called in when trial is three weeks out and something critical has gone unfound. By then, witnesses have moved or stopped cooperating, physical evidence has deteriorated, and memories have faded. The earlier we’re brought in, the more we can do.

Early engagement also gives us time to do this right. A thorough witness canvass, a proper social media preservation, or a detailed background investigation on a key witness takes time. Rushed work produces thin documentation — which is exactly what you don’t want when you’re heading into court.

Be Specific About What You Need

A good PI can handle a wide range of tasks, but scattershot assignments produce scattershot results. The more clearly you can define what you’re looking for, the more effectively we can work. ‘Find out everything about this witness’ is a starting point; ‘document this witness’s prior relationship with the alleged victim and verify their whereabouts on the night in question’ is an assignment we can execute against.

If you’re not sure what you need, that’s also fine — part of what we do is help attorneys identify the gaps in a case. Walk us through the facts and let us flag where the investigation is thin.

Understand What Courtroom-Ready Documentation Looks Like

Not all documentation is created equal. Video footage without GPS metadata and timestamp verification is easy to challenge. Social media screenshots without forensic preservation are inadmissible in many jurisdictions. Interview recordings without proper notice (where required) have chain-of-custody issues.

We structure everything we produce with litigation in mind from the start — because retrofitting documentation after the fact doesn’t work. If you need an investigator who can sit in the witness chair and walk a jury through how evidence was collected, that’s a conversation worth having before we start the job.

A Note on Criminal Defense Specifically

Criminal defense investigation is a specialty. It’s not the same as running background checks for a corporate client or conducting surveillance in a civil matter. The constitutional stakes are different, the timelines are often court-imposed, and the subjects are sometimes hostile. We’ve worked criminal defense cases across Georgia and Alabama — from felony trials to post-conviction relief matters — and we understand the legal landscape these cases live in.

If you’re a defense attorney in Georgia, Alabama, or South Carolina and want to talk through a case, reach out. We offer confidential consultations and can give you a direct assessment of what investigative support is realistic given your timeline and budget.
