What our clients say


Testimonial Photo

” had been in a legal battle with my Brother for over a year regarding my Mothers will. When my friend told me Rick Irving from Landmark Investigators was traveling to Naples to do an investigation at his business I asked if I could talk to him. My friend thought it would be a good idea and boy was he right. Although Mr. Irving was only in town for 10 days he was able to find enough information to get my Brother to settle immediately. He also did a great job for my friend. We both talk about him from time to time. What he does is a mystery to us but one thing is for sure he is really good at it. “

I would be sitting in a prison cell right now if my parents had not hired Landmark Investigators when I was arrested . They believed in me and found the evidence to free me. I was frustrated beyond believe and not thinking clearly. Admittedly I did not handle things properly until I started seeing reports from the Investigator supporting my innocence. “

” When I made the decision to adopt my Granddaughter I never envisioned the push back I would get from her biological Father as he had not been heard from in years. Landmark Investigators found information that persuaded the judge to rule in our favor. We will be forever grateful. They are the best.. “

” Our firm worked with Landmark Investigators for 2 years on a major class action case that resulted in a $5 Billion settlement. Landmark stuck it out when it appeared at times we were not making any progress. Through their hard work we were able to find the class members we needed to present our case. Landmark will always be the first call we make when we need Investigators.. “

Common Frauds And How To Avoid Them

City Inspector

A person with a clip board shows up, saying he or she needs to inspect the electrical wiring, heating unit or plumbing. After the inspection, you’re told the situation is dangerous and repairs are needed. The inspector has a friend, though, who can help out. You can get stung twice: you probably didn’t need the repairs and the repair work they do is of poor quality. Either way, you end up reaching into your wallet or purse.

Anyone who claims to be a government official or an inspector will carry identification. Checking it is smart, but keep in mind that IDs can be fake. Call the person’s department for verification by looking up the government number in the White Pages phone directory or using 411 information. Don’t accept the number from the “inspector” or get it off the business card.

Pest Control

An “inspector” or “exterminator” visits your home to check for termites or other pests. You may be told that there have been problems in the building or neighborhood. The exterminator finds signs of infestation and shows it to you. But the insect- or termite infested wood he claims came from your home, he brought with him.

Is your partner cheating?

Use these tips as a reference to look deeper into whats going on. Please do not think that your partner is cheating just because he or she exhibits some of these traits. Be 100% sure before you accuse. If in doubt call a professional investigator.

Changing Habits

Your husband’s been coming home from work everyday for the past ten years at 5 p.m., but recently he’s pushing the arrival time to 9 p.m. or so. Or maybe he use to go out with pals once a week and now he’s stepping out three to four times a week, acting secretive and jumpy. Plus Mr. Practical traded in the mini-van for a Dodge Viper and you’re no longer invited to ride along.

Occasionally there are reasons why you can’t join him, but he should be making an attempt to involve you. Invite yourself along when he goes out with his friends. If he’s working late, offer to bring him dinner If he declines, look into the situation.

Leaving Early and Returning Late

Is he leaving for work much earlier than he needs to and coming home later? Unfaithful partners may leave the house right after their shower, just to have breakfast with someone else. Is this another change habit that is unexplained?
