How we help you
Relationship situations we investigate
Every case is different, but these are the most common reasons people come to us for relationship investigations.
Suspected infidelity
Changes in behaviour, unexplained absences, a guarded phone. You deserve to know the truth. Surveillance provides clear, factual answers within days.
Divorce evidence
Your solicitor needs evidence of behaviour, unreasonable conduct or hidden assets for divorce proceedings. We gather it discreetly and present it professionally.
Cohabitation checks
Your former partner claims to live alone but you believe they are cohabiting with a new partner. Evidence of cohabitation can affect your financial obligations.
Online dating verification
You have met someone online and want to know they are genuine before meeting in person or deepening the relationship. We verify their identity and background.
Child welfare concerns
You are worried about the environment your children are in during contact visits. We observe and document conditions discreetly.
Pre-marital checks
Before making a lifelong commitment, background checks can reveal financial problems, previous marriages, criminal records or other concerns.

Real outcomes
Relationship investigation case examples
All names and identifying details have been changed to protect client confidentiality.
The overnight trips
The challenge
A husband had started taking regular overnight "business trips" that could not be verified through his employer. His wife was consumed by doubt.
Our approach
Two nights of surveillance confirmed that the trips were not business-related. Photographic evidence documented his movements and meetings.
The dating app discovery
The challenge
A woman discovered her partner of three years was active on multiple dating apps. He denied it, claiming his account must have been hacked.
Our approach
Digital investigation confirmed active, regular use of the apps with verified logins from his phone. A surveillance operation documented a meeting arranged through the app.
The cohabitation dispute
The challenge
A man paying £2,200 monthly maintenance believed his former wife was cohabiting with her new partner but she denied it in court.
Our approach
Three weeks of documented observation showed the partner arriving six evenings a week, leaving each morning, receiving deliveries and keeping a vehicle at the property.
Transparent pricing
Relationship investigation costs
We believe in honest pricing. You will receive a clear, fixed-fee quote before any work begins.
