Infidelity investigations: from initial question to report
People considering an investigation often want to know what happens in practice. A careful process begins with a specific question and clear agreements. These are the decisions to discuss before any work starts.
Explore our infidelity investigation service
Start with a defined question
Explain what uncertainty you want to resolve and why it matters to you. The investigator then assesses whether the assignment can be accepted. A general wish to know everything about someone is not a workable investigation brief.
Agree on limits and budget
Discuss relevant dates, available information and the charges involved. Agree on updates and on decisions to extend or stop work. This keeps the scope of your instruction clear.
What does the report tell you?
A report describes relevant observations and their circumstances. A meeting does not automatically establish an intimate relationship. Limitations, such as an interrupted observation, matter too. An absence of findings only concerns the period investigated.
How should you use the findings?
Findings may support your personal decision-making. Discuss any intended legal use with your legal adviser; suitability depends on the circumstances. Conclusions should remain consistent with the facts established.
