What Is Cohabitation Surveillance?

Cohabitation surveillance is the process of gathering evidence to determine whether two people are living together as a couple without being married. It is most commonly used where cohabitation may affect legal or financial obligations, such as spousal maintenance or child support.

This type of investigation typically involves discreet, lawful surveillance to observe day-to-day living arrangements, routines, and behaviours that indicate a shared domestic life rather than casual visits.

Why Do You Need Cohabitation Surveillance?

There are many reasons why professional cohabitation surveillance may be necessary.

Divorce & Spousal Maintenance

Confirm whether an ex-partner is cohabiting and potentially breaching maintenance agreements, with evidence that can support reducing or ending payments.

Child Welfare & Living Arrangements

Understand who is living in the property and how this may impact a child’s welfare, living conditions and financial situation.

Financial & Asset Disputes

Identify shared living arrangements that may affect ongoing financial support, asset discussions or maintenance reviews.

Landlords & Property Owners

Verify unauthorised occupants, subletting or tenancy breaches with clear evidence of who is living at the property.

How to Prove Cohabitation?

In the UK, gathering reliable evidence of cohabitation can be challenging without professional support. To establish cohabitation in a way that may be relied upon in court, structured and lawful surveillance is required. 

Before any surveillance begins, we take time to understand your situation, objectives, and any relevant legal considerations. Based on this, we recommend suitable surveillance options, allowing you to choose the approach that best aligns with your case.

In matters relating to divorce or maintenance agreements, this may involve a defined surveillance period focused on the property in question, your former spouse, and, where relevant, their new partner. This approach is commonly referred to as static surveillance.

Static surveillance involves an investigator observing a specific address over agreed timeframes, recording patterns of activity, arrivals and departures, and behaviours that may indicate shared living arrangements. Observations are carried out discreetly and in public spaces only.

In most cases, our investigators can provide same-day updates, including date and time-stamped photographic and video evidence where appropriate. These findings are then compiled into a clear, detailed surveillance report designed for review by you or your solicitor and, if required, for use in court proceedings.

Our surveillance reports typically include the agent’s written notes and photographic evidence at no additional cost.

Covert Cohabitation Surveillance

We offer both overt and covert cohabitation surveillance. A covert investigation is when a detective remains completely undetected.

Our investigators will work closely with you to understand your needs. We will walk you through the process of evidence gathering and the kind of cohabitation surveillance that we will undertake. We understand that you may be nervous about hiring a private detective, and we will make every effort to put you at ease.

Cohabitation can be difficult to define. Contact our friendly team today to get advice on the most adequate evidence to prove your case.
