Every season has its rhythm in the private investigation business, and summer is no exception. Schools let out, families travel, divorce filings spike after the school year ends, and fraudsters take advantage of warmer weather to stage the kinds of incidents that fill an investigator’s docket. For PIs in 2026, the top summer cases for private investigators include travel-related infidelity and asset investigations, child custody and visitation disputes, and insurance fraud cases, particularly workers’ compensation, slip-and-fall, and auto fraud claims.
If you operate a PI firm or work as a freelance investigator, understanding these seasonal patterns helps you market smarter, staff appropriately, and price your services to reflect the work involved. It also helps you anticipate the risks, and that’s where insurance comes in. At El Dorado Insurance Agency, we’ve insured private investigators for decades, and we see the claim trends that accompany each of these case types.
1. Travel Cases: Infidelity, Asset Tracing, and Surveillance Abroad
Summer is high season for travel-related investigations. Family vacations, business trips, weekend getaways, and the simple statistical reality that people are more mobile in warm weather all combine to produce a surge in surveillance work. Common scenarios include suspected infidelity that requires the investigator to follow a subject to a vacation destination, asset tracing where a spouse or business partner is suspected of moving funds offshore during a “vacation,” missing-persons cases involving family members who have traveled and gone silent, and corporate matters where an employee suspected of IP theft is meeting competitors or buyers under cover of a vacation.
Travel cases are operationally complex. They require fast deployment, often across state lines or international borders. The legal landscape changes the moment your subject crosses a jurisdiction. What’s permissible surveillance in Texas may be a crime in California, and what’s lawful in the United States may violate privacy laws in the European Union or Mexico.
Investigators handling travel cases in 2026 should be familiar with the Department of State travel advisories for any country where work might take them, the privacy regulations that apply in the destination jurisdiction, and the current state of cross-border data transfer rules. The General Data Protection Regulation in Europe continues to be aggressively enforced, and California’s privacy framework has been tightened further. Mishandling a subject’s data, even unintentionally, can produce regulatory exposure that dwarfs the value of the case.
Operationally, the experienced PI knows to confirm the subject’s travel before booking flights, build local contacts in the destination city when possible, document chain of custody on every photograph and recording, and maintain real-time communication with the client without revealing operational details over insecure channels.
2. Custody and Visitation Disputes
Family law attorneys will tell you that summer is the busiest custody season of the year. Two patterns drive the volume. First, divorces filed at the beginning of the year are entering the discovery and motion-practice phase by mid-summer, exactly when behavioral evidence carries the most weight. Second, court-ordered summer visitation schedules, those long, multi-week stretches that flip the school-year custody arrangement, surface every weakness in the parenting plan and produce a steady stream of complaints, allegations, and counterclaims.
The PI’s role in custody work has evolved. The traditional surveillance gig, sitting outside an ex-spouse’s house with a long lens still exists, but today it’s only one piece of a broader investigation that often includes social media monitoring (within the bounds of American Bar Association ethics guidance on counsel-directed investigations), background work on new partners introduced into the child’s life, school and daycare verification, vehicle and travel pattern analysis to confirm or refute claims about the parent’s whereabouts during custody time, and substance-abuse-related observation when court-ordered testing isn’t in place.
Investigators who work custody cases need to be especially careful about two things. First, the standard of evidence is high; photos, video, and time-stamped records that would survive cross-examination are the goal, not anecdotes. Second, the work touches children, which means the PI’s conduct is held to a particularly high standard. Surveillance must never be conducted in a way that would alarm or interact with a minor child, and any documentation involving children should be handled with the same care a custody evaluator would use.
The Association of Certified Family Trauma Professionals and the National Council of Investigation and Security Services both publish helpful guidance on best practices in this space.
3. Insurance Fraud: The Summer Surge
Insurance fraud is a year-round problem, but several trends spike in summer. Workers’ compensation fraud climbs as construction, landscaping, and outdoor maintenance work reach peak volume. The classic claim; a worker reports a back injury that prevents him from working but is later observed roofing his cousin’s garage on a Saturday, is just as common in 2026 as it was 20 years ago, just better disguised. Slip-and-fall and premises liability fraud increase with foot traffic to pools, water parks, beaches, and outdoor entertainment venues. Auto fraud spikes alongside summer driving volume, with staged-collision rings particularly active in major metropolitan areas.
The Coalition Against Insurance Fraud publishes annual data on these trends, and the numbers are staggering; fraud is conservatively estimated to cost American consumers and insurers more than $300 billion per year in higher premiums and direct losses.
For PIs, fraud work is some of the most reliable revenue in the business because insurance carriers, third-party administrators, and self-insured employers maintain rotating panels of investigators they call on for surveillance, statements, and background research. Building or maintaining a position on those panels is a multi-year relationship investment that pays dividends for the long haul.
Effective fraud investigators in 2026 are leaning heavily on technology. Open-source intelligence tools, license plate recognition databases, social media analytics, and drone-based surveillance (where lawful) all extend what a single investigator can accomplish in a workday. The Federal Aviation Administration’s drone rules continue to evolve, and any PI using a drone for surveillance needs to maintain current Part 107 certification and operate within the published airspace and privacy restrictions.
The Risk Profile and Why Insurance Matters
All three case types, travel, custody, and fraud, share a common thread: they generate complaints, claims, and lawsuits at a rate well above other PI work. A travel case can produce invasion-of-privacy claims across multiple jurisdictions. A custody case can produce defamation, intentional-infliction, or even stalking allegations from the surveilled parent. A fraud case can produce personal-injury claims against the investigator if a subject becomes aware of surveillance and a confrontation occurs.
The insurance program for a working PI firm in 2026 should reflect that risk profile. At minimum, that means private investigator general liability insurance tailored to the specific services you offer, professional liability or errors and omissions coverage for the inevitable disputes about what your work concluded or failed to conclude, commercial auto coverage for vehicles used in surveillance, and cyber liability coverage given the volume of sensitive personal data PIs handle. Investigators carrying firearms or working armed protection details on the side need additional armed services endorsements or separate policies, depending on state law and carrier appetite.
A specialized broker also helps with the contract side; engagement letters that limit your liability, confidentiality clauses that protect your work product, and clear scope language that prevents clients from reframing the case after the fact.
Closing Thoughts
The PIs who thrive in summer 2026 are the ones who treat the season strategically. They market into the case types that surge, staff up to handle the workload, document meticulously, and keep their professional and operational risk well-insured.
