Do You Think Your Husband, Wife or Partner is Having an Affair?


It’s easy to rule suspicions out as paranoia. But you know in your gut when something’s just not right. When your husband, wife or partner starts acting differently or distances themselves for no apparent reason, there are questions that need answering. Our team of cheating partner investigators will discreetly establish whether there’s anything concrete behind your suspicions to empower you to confront your partner and gather irrefutable evidence for use in a legal setting.

We’re so confident in the level of service we offer that we even offer a full refund should our cover ever be blown on your job.

Turn Your Fears Into Facts With Our Three-Step Cheating Partner Investigation Process

Step 1. Initial Consultation

We will start with an informal conversation about your suspicions. Our friendly case handler will listen, take all the details, and give you an initial assessment based on what you’ve told us before formulating a strategy to get to the bottom of your concerns.

Step 2. Evidence Gathering

Cheating partner investigations typically involve vehicle tracking, or surveillance, or both. You’ll receive real-time updates on any vehicle locations and a written report of all movements within 24 hours of any surveillance. Video evidence can also be provided where appropriate.

Step 3. Move On With Your Life

Whatever we uncover, the next move is down to you. We’ll supply you with all the evidence we can to allow you to make a decision on the next steps with surety. And then, one way or the other, you can get on with your life without a black cloud hanging over it.
