Matrimonial and Relationships

Hiring a matrimonial private investigator to investigate suspected infidelity will never be an easy decision to make. We understand the distressing nature of the situation, which is why we tailor investigations to your case and budget and value discretion as paramount to sensitive operations.

Covert surveillance is one of the best ways to identify the facts. Our team of specialist matrimonial investigators leave no room for doubt when investigating a case and will help you confront your suspicions by getting you the information you need. Our professional investigators can conduct discretionary investigations anywhere in the UK.

Common Signs of a Cheating Partner 

If you believe your partner is unfaithful, you may have observed some major changes in their behaviour that are cause for suspicion and may warrant a private investigation:


▪️ Distant or disinterested


▪️ Refuse to answer the phone around you or leave it lying around


▪️ They work late or more often than usual


▪️ They smell strongly of someone else’s perfume or aftershave


Modern communication is also a common reason to believe your partner could be cheating. Today there are endless opportunities to hide your online activity – whether it be via email, social media or pin protected messages – you cannot keep track of it all. Our specialist team of private investigators are trained to conduct thorough online investigations as well as physical pursuits.

How do we carry out matrimonial surveillance?


We know the decision to hire a matrimonial investigator is a difficult one. Letting a stranger into your relationship is daunting, but the ‘not knowing’ aspect can often be harder to cope with.


Rest assured Mac-Investigations conduct themselves respectfully and act with the utmost sensitivity when handling matrimonial investigations.
