They say that love makes the world go around. But when there is a suspicion that your loved one is unfaithful, a person’s whole world can suddenly grind to a halt.

Relieving your anxieties

Naturally, this is a highly sensitive issue if you have reason to suspect infidelity by your loved one.

If you find yourself doubting your partner, the biggest dilemma you may be facing is uncertainty – simply not knowing the facts and thus becoming distraught through excess worry and concern.


Absolute clarity

At PDL, we can help you through these concerns by discreetly and sensitively uncovering the facts – giving you absolute clarity on the situation so that you can then move forward in the appropriate manner.

We will talk through all your suspicions – listening carefully with a practised ear – and then, with an agreed plan of action in place, uncover the actual evidence to give you the knowledge that you need.

Our relationship surveillance techniques combine the very best of classic and modern methods to successfully gather the evidence vital to resolve your issues about a cheating spouse or partner’

Leaders in Sophisticated Modern Surveillance Techniques

At PDL, we always use the most sophisticated methods and state-of the-art tools to help discover a cheating spouse. In the online world, for example, we are at the forefront of using advanced algorithms and specialist intelligence databases to speed the process. This, of course, is on top of the usual tried and tested covert surveillance techniques where we can use the very latest and best GPS vehicle tracking systems to help trace a partner’s movements.
Also, as you will see from some of our brief Case Studies below, our investigations often span international borders. For that reason it’s crucial that you choose a private investigative team that has relevant global experience to gather proof of infidelity.

A Valued and Trusted Track Record

PDL has a proud and exceptional track record of success and our Matrimonial Investigation Services have been answering clients’ emotional concerns for over 26 years.

During that time, we have frequently uncovered the evidence that a partner never wants to hear – that their loved one is indeed conducting an affair.

Yet our investigations can often reveal that those suspicions can sometimes be unfounded. It could be that there is another issue at play: health problems, perhaps, or areas such as addictions or mounting work pressures.

" What we know for certain is that every case is unique and that’s why our service is always personally tailored to your specific concerns "
