An infidelity investigation is a discreet process used to establish whether a partner is being unfaithful. It typically involves surveillance, evidence gathering and behavioural analysis to provide clear, factual information.

At SIASS, investigations are conducted professionally and lawfully, with a focus on obtaining accurate evidence such as photographic or video documentation where appropriate. Clients receive a detailed report outlining the findings, enabling them to make informed personal or legal decisions based on verified information rather than suspicion.

A welfare check investigation is carried out to confirm the safety and wellbeing of an individual where there are concerns about their health, circumstances or vulnerability.

This may involve locating the individual, making discreet enquiries, and verifying their current situation. Welfare checks are often requested by family members, legal representatives or organisations when contact has been lost or concerns have arisen.

SIASS conducts welfare checks sensitively and professionally, ensuring that any findings are handled with care, discretion and respect for all parties involved.
