Personal Relationship Investigations Conducted in Complete Confidence

We are experienced private investigators with a worldwide reputation.

Personal Relationship Investigations

Research Associates has specialised in matrimonial investigation (i.e. cheating partners/spouses) since being established in 1977 and continues to broaden its well-documented capabilities.

Matrimonial investigation is the most delicate of all matters dealt with by Research Associates, typically requiring a particularly sensitive approach. As such, we aim to balance our many years of professional experience with understanding and tact for the specific situation presented.

Why Choose Us?

Our committed and approachable matrimonial investigators/detectives answer all questions with utmost consideration; aiming to provide objective professional advice and incisive options, all in full confidence and without obligation.

Once an overview of the current situation and required objectives are understood, a logical plan of action and costing will be agreed upon. Once you decide to go ahead, a senior private investigator will oversee the case and act as the sole point of contact, to provide a highly personalised interactive service through to completion. Discretion and total confidentiality are viewed as paramount in all matters at all times.

Determine the Truth

When there are suspicions that a partner may be hiding something significant, Research Associates offers confidential support and assistance by understanding the often subtle presenting evidence, which typically indicates the best lines of investigation to follow. We are then able to provide discreet factual information on a partner’s activities, allowing the truth to be documented in a clear, focused report.

Research Associates’ private investigators have many years of experience in legally obtaining personal information in a professional, covert and discreet manner. An investigation will reveal facts about an individual’s background (both past and present), thereby exposing the truth relating to their integrity. We substantiate or validate the information we gain before reporting to clients, ensuring accuracy and precision.


All Research Associates’ reports are focused, detailed and professional. As well as reporting to you in person (typically by telephone), our report documents the presenting situation and clearly demonstrates we have undertaken an ‘impact assessment’, which shows we have considered the legality of each case. Our report then goes on to document the summarised results of our investigation and where applicable, our Observation Log will objectively demonstrate the following: date; time; place and factually what is observed. This section of the report will be supported by date- and time-stamped video evidence, which is gathered covertly where doing so does not compromise surveillance.

Before deciding to instruct, our approachable matrimonial investigators/detectives answer all questions with expert understanding based on decades of experience. We aim to present objective professional advice and lay out a clear plan of action in confidence and without obligation.

Our reports are designed to allow the reader to clearly understand both the presenting situation, along with the resulting evidence; whether the reader be a court in the UK or any other jurisdiction, a family member or any other third party.
