Discovering that a spouse may be unfaithful is one of the most distressing experiences a person can face. For many people in Metairie and the surrounding Jefferson Parish area, the decision to hire a private investigator is not taken lightly. It often comes after weeks or months of behavioral changes, unexplained absences, suspicious phone habits, and eroding trust. A licensed PI cannot tell you whether your marriage is salvageable — but they can give you the factual clarity you need to make informed decisions about your next steps.

This article walks through the full process of an infidelity investigation in Louisiana: what happens at each stage, what evidence can be gathered legally, what it costs, and how that evidence can be used in legal proceedings.

Stage One: The Consultation

Every infidelity investigation begins with a confidential consultation. Before any surveillance is planned, a licensed PI will want to understand the specifics of your situation. Expect to discuss:

• Your spouse’s typical daily routine (work schedule, gym times, regular social activities)

• The vehicles they drive, including make, model, color, and license plate

• Any known or suspected locations of concern (a coworker’s address, a particular bar or restaurant)

• Your goals for the investigation — confirming or disproving suspicion, gathering evidence for divorce proceedings, or both

• Whether children are involved and whether a custody investigation may be needed alongside the infidelity inquiry

The consultation is also the time to verify the PI’s credentials. Confirm their LSBPIE license number and look it up at lsbpie.com before signing anything. Our article on how to verify a PI license in Louisiana explains exactly what to check.

Stage Two: Building the Surveillance Plan

Based on the consultation, the investigator will develop a surveillance plan tailored to your spouse’s routines and the most likely scenarios for observation. A well-constructed plan identifies:

• Which days and time windows offer the highest probability of productive surveillance

• Starting locations (home address, workplace, known frequent stops)

• Whether mobile surveillance (vehicle-based following) or stationary surveillance (fixed observation point) is more appropriate

• Whether a single investigator or a team is needed for complex routes or multiple locations

Good planning reduces wasted hours and, therefore, reduces your total cost. An investigator who charges by the hour without any planned strategy wastes both your time and money. Louisiana investigators working in the New Orleans metro area — which includes significant traffic on I-10, Veterans Memorial Boulevard, and the Causeway — are experienced with urban mobile surveillance in dense suburban environments like Metairie.

Stage Three: Field Surveillance

Surveillance in an infidelity investigation is conducted entirely in public or semi-public spaces. Under Louisiana law, investigators may observe and photograph any activity that occurs in a location where there is no reasonable expectation of privacy. This includes streets, parking lots, restaurants, parks, shopping centers, and the exterior of residences.

What investigators cannot do is enter private property without permission, look through windows into private spaces, or place recording devices inside a home. The legal limits of surveillance in Louisiana are covered in detail in our article on Louisiana surveillance laws for private investigators.

Evidence Gathered During Surveillance

A typical infidelity surveillance operation produces the following types of evidence:

• Time-stamped photographs: Still images documenting the subject’s location, companions, and activities. Metadata (GPS coordinates, date/time) embedded in digital image files strengthens authenticity.

• Video footage: Continuous video provides context that still images cannot — how long two individuals were together, the nature of physical contact, the progression of events.

• Location logs: Detailed written or digital logs noting every location visited, time of arrival and departure, and notable observations. These are part of the formal investigation report.

• Witness documentation: In some cases, investigators note the presence of corroborating witnesses, though formal witness interviews are less common in infidelity cases than in custody or fraud investigations.

If the investigation includes open-source intelligence (OSINT) analysis, the investigator may also document social media activity, check-ins, and geolocation data that corroborate or contradict stated alibis.

Stage Four: The Report

At the conclusion of the engagement — or at agreed-upon check-in points for longer investigations — the investigator delivers a written report. A professional infidelity investigation report will include:

• A chronological narrative of all surveillance activity

• All photographs and video files, properly labeled and time-stamped

• Location logs with times, addresses, and observations

• A summary of findings and their significance

• An affidavit from the investigator certifying the accuracy of the report (required for court use)

This report is the deliverable your attorney will work with if you proceed to divorce or custody proceedings. A well-documented report from a licensed LSBPIE investigator carries substantially more legal weight than informal observations or undocumented phone recordings.

Typical Costs for an Infidelity Investigation in Metairie

Infidelity investigation costs in the New Orleans metropolitan area — which includes Metairie, Kenner, and Jefferson Parish — generally fall in the range of $1,250 to $4,500 total for a complete engagement. This estimate assumes two to four surveillance sessions of four to six hours each. Several variables affect the final cost:

• Hourly rate: Licensed Louisiana PIs in this market typically bill $75–$150 per hour for surveillance. Some firms offer flat-rate packages.

• Number of investigators: Complex mobile surveillance in urban environments often requires two investigators to avoid detection. A second investigator doubles the hourly cost but substantially increases the quality of coverage.

• Equipment: Video drone deployment, specialized long-range camera equipment, or GPS tracking (where legally permitted under Louisiana GPS laws) may add incremental costs.

• Travel: If surveillance leads outside the metro area, mileage and time are typically billed.

Typical Timeline

Most infidelity investigations in Metairie produce usable evidence within one to three weeks. The timeline depends on how predictable the subject’s schedule is and how quickly the investigator can identify productive surveillance windows. Investigations that begin with good intelligence from the client — accurate routine information, known associate locations, vehicle details — tend to resolve faster than those that start cold.

Investigators will often recommend beginning surveillance on days that the client has reason to suspect activity is most likely. Weekends, late evenings after work, and days when the client is out of town are common high-probability windows.

How Evidence Is Used in Louisiana Divorce Proceedings

Louisiana is both a community property state and a fault-based divorce state. Under Louisiana Civil Code Article 103, fault grounds for divorce include adultery. A spouse who can prove adultery through admissible evidence — including properly documented PI surveillance reports — may be able to pursue a fault-based divorce, which can affect property division and spousal support determinations in some circumstances.

Your family law attorney will advise you on how best to deploy the evidence in your specific case. It is important that you do not share the PI’s report with anyone other than your attorney before it is presented in a legal proceeding, as premature disclosure can create complications. If children are involved, the PI’s findings may also be relevant to custody arrangements — see our guide on child custody investigations in Jefferson Parish.

Emotional Considerations

A professional PI will present facts without editorial comment. The report will show what was observed, when, and where — not conclusions about your marriage or your spouse’s character. This objectivity is necessary for legal admissibility and professional integrity, but it can feel clinical when the subject matter is deeply personal.

It is worth speaking with a counselor or therapist during or after an infidelity investigation, regardless of the outcome. Some clients find that the investigation confirms their worst fears; others find that the investigation exonerates their spouse, which requires its own kind of processing. Either way, having objective evidence is almost always better than living with unresolved suspicion.

What to Bring to Your First Consultation

The more information you can provide at the initial consultation, the more efficiently the investigator can build a surveillance plan. Bring or have ready:

• Recent photographs of your spouse (for identification in the field)

• Descriptions and photos of all vehicles they use

• Their typical work schedule and any known after-work patterns

• Addresses of concern (workplace, a specific person’s home, a gym, a bar)

• Any text messages, emails, or social media activity that triggered your suspicion (do not access accounts you are not authorized to use)

• A general sense of your budget and timeline

All licensed PIs in Louisiana are bound by strict confidentiality obligations. Everything you share in a consultation stays between you and the investigator — and, if you proceed, your attorney.
