Cardiff Private Investigator Case Study
Serving Divorce Papers to an Illusive Spouse in Cannock, Staffs:
A client from Cardiff approached Bond Rees in April 2024 for assistance in serving divorce papers to an ex-partner who had denied previous attempts over the past two years. From years of stagnation, the client expressed the process had negatively impacted her mental health and turned to Bond Rees for assistance in serving the divorce papers to allow her to proceed with the legal process.
What we did:
First we began collecting information on the client’s ex-partner and traced his new address to be in Exeter, three hours away from his prior address when living with our client. PIs then gathered information on the partner’s interests to determine the most effective process to serve the legal documents without arising suspicion.
Our private investigators then reached out to contacts in the local area and identified the ex-partner was commonly known to be gambling in a casino on Hemmingway Road and attending bookies on Crwys Road. We deployed PIs strategically on foot across the area to find him.
The Results:
After a 6 day investigation, our detectives spotted the ex-partner in the local casino and served the divorce papers after sparking up a brief conversation about the casino’s games. The ex-partner surprised with the serving but, as it was caught on security camera, he could not refuse it. He was now required to cooperate with the formal divorce process to which our client was relieved with the successful serving. Our client was very happy with the outcome.
Private investigator FAQ for i-Spy Detectives Cardiff
Is it legal to hire a private investigator in Cardiff?
Yes, it’s completely legal. People across Cardiff and South Wales hire private investigators every day for personal, legal and business reasons. What matters is choosing an agency that follows UK laws covering surveillance, evidence handling and data protection. At iSpy Detectives, all work is carried out lawfully and transparently, so clients never need to worry about the legality of the investigation.
What is a private detective agency allowed to do?
A qualified private detective in Cardiff has a wide range of legal tools available to help uncover the truth. This includes surveillance, background checks, vehicle GPS tracking (where permitted), online and social media investigations, and open-source intelligence gathering.
We never hack devices, break into property or use illegal methods — but our training, experience and specialist technology mean we can often uncover information that isn’t easily accessible to the public.
When should I consider hiring a private investigator?
People reach out to us when they need answers but can’t find them on their own. You might want to trace someone’s whereabouts in Cardiff or Newport, check whether a partner or employee is being truthful, investigate potential fraud or verify that a business is legitimate.
If you’re stuck, suspicious or simply want reassurance, a Cardiff-based private investigator can provide clarity discreetly and professionally.
How much does a private investigator in Cardiff cost?
Costs vary depending on the type of investigation. Surveillance, people tracing, background checks and corporate investigations all require different levels of time and resources. Some cases can be resolved in a matter of hours, while others may take longer. Once we understand your situation, we’ll provide a clear, honest quote with no hidden fees.
How discreet are your investigators?
Discretion is central to everything we do. Our Cardiff private investigators have years of experience handling sensitive cases for individuals, families, businesses and high-profile clients across South Wales.
Every investigation is carried out quietly, respectfully and confidentially from start to finish.
Do you take on investigations outside the UK?
Yes. Although based in Cardiff, we manage international investigations too. We work with trusted partners across Europe, North America, Asia, Australia, the Middle East and Africa.
If you need overseas tracing, global surveillance or specialised technical support, we can coordinate the entire process for you.
Do you offer bug sweeping services in Cardiff?
We do. Our technical team carries out professional bug sweeps for hidden cameras, listening devices and tracking equipment in homes, offices, hotel rooms, rental properties and vehicles throughout Cardiff, Newport, Swansea and the wider South Wales region.
Corporate clients, high-net-worth individuals and people handling sensitive information often come to us for peace of mind.
I think I’m being followed. Can you help?
Yes, absolutely. Our counter-surveillance team — many of whom come from military and specialist security backgrounds — can discreetly determine whether someone is watching or monitoring you.
We’ve supported worried individuals, business leaders and public figures across Cardiff and South Wales, ensuring they remain safe and protected.
What does a private investigator actually do day-to-day?
Every day is different. One day we may be conducting surveillance in Cardiff Bay or Swansea, the next we might be performing background checks, tracing a missing person, or gathering evidence for a legal dispute.
Investigators also review footage, analyse data and prepare detailed reports — all with precision and discretion.
How long does a private investigation usually take?
There’s no fixed timeline. Some tracing cases can be completed quickly, while surveillance might require several days. More complex corporate investigations can take longer.
Once we understand your goals, we’ll give you a realistic estimate of how long the process should take.
Can a private investigator find someone quickly in Cardiff?
Often, yes. Thanks to our local knowledge of Cardiff, Newport, Bridgend, Barry, Caerphilly, Penarth and beyond — along with access to specialist databases and tools — we can usually locate people faster than clients expect. This includes missing relatives, debtors and individuals who have dropped out of contact.
Can a private investigator retrieve phone records or text messages?
No — and no legitimate investigator will claim they can. Accessing someone’s private messages or phone data without consent is illegal.
What we can do is gather lawful evidence such as surveillance footage, social media analysis, OSINT investigation, background checks and behavioural insights.
Can evidence collected by a private investigator be used in court?
Yes, as long as it’s obtained legally. We follow strict protocols to ensure that photographs, video recordings, logs and witness statements can be used in court proceedings, employment disputes and civil cases across Wales.
Do you provide urgent private investigator services in Cardiff?
Yes. We understand that some situations require immediate attention. Whether it’s urgent surveillance, a sudden personal matter or a pressing business concern, we can often provide same-day assistance across Cardiff and surrounding areas.
Do you conduct cheating partner or infidelity investigations?
We do. Infidelity investigations are one of the most common reasons people contact a private investigator in Cardiff and South Wales.
We handle these cases sensitively and discreetly, providing clear, actionable evidence so clients can make decisions with confidence.
Do you offer corporate investigations in Cardiff?
Yes. We support businesses in Cardiff, Swansea, Newport and the wider region with cases involving employee misconduct, fraud, internal theft, due diligence, asset verification and competitor intelligence.
Our corporate clients value our confidentiality, fast reporting and legally compliant approach.
Which areas of Cardiff and South Wales do you cover?

If you’re unsure whether we cover your area, just ask — we likely do.

Yes. Discretion is essential in private investigation work. Whether it’s surveillance, tracing or background checks, the subject will not know that an investigator is involved.
All work is carried out legally, quietly and respectfully.
