Understanding the Private Investigation Process

1. Initial Consultation: Identifying Your Case Needs

The first conversation identifies the factual question, the decision it affects, the deadline and the information already available. A useful scope is narrower than “find everything.”

Be clear about deadlines and the facts counsel needs developed. No investigator can promise a case outcome.

2. Strategic Case Planning

The plan identifies priority leads, lawful methods, likely costs and stop points. Attorneys—not private investigators—issue subpoenas through legal process.

Investigators often work with attorneys to develop and document facts. The court determines whether evidence is admissible and how much weight it receives.

3. Fieldwork and records

This is where most of the hours go. Depending on the scope, it may include surveillance during a defined window, locating and interviewing witnesses, retrieving records under proper authority, canvassing an area, or documenting a scene before it changes.

Two practical points shape the timing. Third-party video — business CCTV, doorbell and dashcam footage — is routinely overwritten within days to a couple of weeks, so it is pursued first regardless of what else is planned. And records custodians work to their own schedules; school, medical and agency files are measured in weeks, not days.

Timing note: Investigators brought in early can preserve material that is simply gone by the time trial preparation starts. The most common irrecoverable loss in a case is footage nobody asked for in the first fortnight.

4. Analysis and Reporting

A useful report separates four things that are easy to blur: what the investigator personally observed, what a sourced record states, what a third party said, and what the investigator infers from those. Each is weighted differently by a reader, and merging them costs the report its credibility.

It should also state plainly what could not be confirmed, what was attempted and failed, and who declined to speak. A negative result is a finding. Counsel then decides how the work fits the case.

5. Testimony and follow-up

Where required, an investigator can testify as a fact witness — to what they did, saw, recorded and preserved, and to the chain of custody for any item. That is a different role from an expert witness, who offers opinion evidence and must be qualified to the court's satisfaction in a recognised discipline. An investigator who describes themselves as an expert witness on general investigative matters is inviting a challenge that will not help the case.

This is one reason contemporaneous notes and clean documentation matter more than they appear to at the time: the questions on cross-examination are usually about method, not conclusions.

What the process cannot promise

No investigator can promise a case outcome, and none can guarantee that what is collected will be admitted. Lawful collection makes admission possible and keeps the client out of difficulty; relevance, authentication, hearsay and privilege are then argued and a judge rules.

Nor can a scope guarantee a particular finding. An investigation that establishes the opposite of what the client believed has done its job, and the report will say so.
