The Unified Register of Debtors is kept by the Ministry of Justice, it is open, and it holds millions of entries. It is a useful source — provided it is read precisely. The commonest mistake is to draw from it a conclusion it does not contain.
What the register publishes
That enforcement proceedings have been opened against a given person, along with the proceeding number, the enforcement body, and the category of the claim — maintenance, a fine, recovery in favour of a legal entity, and so on.
What the register does not publish
The amount owed. It is not there — not in hryvnia, not as a band, not by implication.
So the only correct phrasing is “registered as a debtor in N proceedings”. “Owes ₴X” cannot be obtained from this source, and no service can derive it from the register without adding something of its own. This site's company profile says the former, and states outright that the register publishes no amounts.
Why the count of proceedings misleads
Proceedings are counted per enforcement document. A large enterprise with thousands of employees can carry hundreds of proceedings over small claims, while a company with a single proceeding may owe tens of millions. The number of proceedings measures how many documents exist, not the size of the problem.
The categories are more informative: a proceeding in favour of the tax authority reads differently from an administrative fine.
How to use it properly
As a reason to ask a question. A company's presence in the register is grounds to ask about a specific proceeding, request confirmation that it has been discharged, or revisit payment terms. It is not grounds for a conclusion about solvency — that data simply is not public.
What about tax debt
A separate register — the list of taxpayers with tax debt — was published as open data by the tax service. Its updates stopped on 23 February 2022. Showing that snapshot as current tax debt would be wrong, so we do not show it at all.
