Can a Private Investigator Find Someone Who Owes Me Money?

Updated 31 July 2026 by K3K Investigations

Yes. Tracing a debtor who has moved, gone quiet or "disappeared" is one of the most common jobs a UK investigation agency does — usually for a fixed fee in the £150–£500 range, often on no-trace-no-fee terms, and usually resolved in days rather than weeks.

People vanish from creditors far less thoroughly than they think. They move house but keep a phone contract; they ignore your letters but register a new company; they block your number but insure a car. Here is how professional debtor tracing works, and — just as important — what to do with the address once you have it.

How debtor tracing actually works

A professional trace is built in layers. It starts with licensed people-tracing data sources — the same regulated data infrastructure used by law firms and financial institutions — processed under UK GDPR with a documented lawful basis (recovering money you are owed is a textbook legitimate interest). On top of that comes open-source research: social media, Companies House appointments, property records, the digital footprint almost everyone leaves. Where the data trail is cold, discreet field enquiries close the gap.

The output is not a guess: a professional trace is confirmed to an evidence-of-residency standard — you receive a current address you can actually rely on for legal proceedings, not just the last place their name appeared.

What information do you need to give the investigator?

More helps, but less than you might think is essential:

Full name (essential) and approximate age or date of birth (very helpful)
Last known address, even years old
Phone numbers or email addresses, current or dead
Anything on employment, trade, vehicles or family connections
The paperwork behind the debt — invoice, loan agreement, court judgment

A name plus a last known address resolves most UK traces. A common name with nothing else attached is harder — an honest agency will tell you the odds before taking your money.

What should you do once the debtor is found?

Finding them is step one; recovery is a legal process, and having a confirmed address unlocks all of it:

Letter before claim to the confirmed address — the formal demand that pre-action rules require, and which alone prompts many debtors to engage.
County court claim. Debts under £10,000 usually go through the small claims track, designed to be used without a solicitor.
Enforcement of a judgment (CCJ). With a judgment and a real address you can instruct enforcement: warrant of control, attachment of earnings, a charging order over property, or transfer to High Court enforcement officers for debts of £600 or more.

Tracing also supports the step people skip: a pre-action means picture — whether the debtor visibly has anything worth enforcing against — before you spend court fees chasing someone with nothing.

What does it cost to trace a debtor?

Most UK agencies, K3K included, quote debtor tracing as a fixed fee, typically £150–£500 depending on how cold the trail is, with no trace, no fee available on suitable cases. Compare that with writing off the debt: for most sums worth chasing, the trace is a small fraction of what silence is already costing you. Wider pricing context is in our cost guide.

When tracing is not the answer

Honesty matters more than a sale: if the debt is approaching six years without acknowledgment or payment (the Limitation Act can make older debts unenforceable), if the "debtor" is a dissolved company with no personal guarantee, or if the person is bankrupt, we will say so before you spend anything. Tracing finds people; it cannot conjure money that is not there — and a five-minute conversation sorts one situation from the other.

Frequently asked questions

Is it legal to have someone traced over a debt?

Yes. Recovering money you are owed is a recognised legitimate interest under UK GDPR, and professional tracing is processed on that documented basis by an ICO-registered agency. What no one may lawfully do is obtain the debtor's bank or phone records by deception — and no legitimate recovery route needs that.

How long does a debtor trace take?

Straightforward UK traces commonly resolve within a few days; colder trails a week or two. We tell you the realistic timeframe when we see the details — and our 24-hour line (020 3343 7007) means you can start tonight.

Can you find someone who has moved abroad to avoid a debt?

Frequently, yes. International tracing takes longer and costs more than a UK trace, but debtors who relocate leave cross-border footprints — property, companies, family ties. Enforcement abroad is a legal question we can point you to the right people for; finding them comes first.

Do you collect the money as well?

No — we are investigators, not bailiffs or a debt collection agency. What we provide is the confirmed address and, where instructed, the means picture that makes recovery action work. Many clients run the small claims process themselves from there; others hand our report to their solicitor.
