A claim form goes out to a Kyiv address by courier, signed for, tracked. Eighteen months later the claimant wins, comes to Ukraine to enforce — and the Ukrainian court refuses recognition because the defendant was never properly served. The courier receipt proves delivery. It does not prove service.

This is the single most expensive procedural mistake foreign counsel make against Ukrainian parties, and it is made at the very first step, when nobody is thinking about enforcement yet.
Ukraine objected to every shortcut in Article 10
The 1965 Hague Service Convention sets out one principal channel — the Central Authority — and then, in Article 10, permits three alternatives: service by postal channels, service through judicial officers of the destination state at the request of officials of the originating state, and service through those officers at the request of any interested person.
Contracting states may object to any of them. Most object to some. Ukraine objected to all three.
| Method | Available for Ukraine? |
|---|---|
| Central Authority (Art. 5) | Yes — the only route |
| Postal channels (Art. 10(a)) | No — objected |
| Via judicial officers, at request of officials (Art. 10(b)) | No — objected |
| Via judicial officers, at request of an interested person (Art. 10(c)) | No — objected |
| Diplomatic or consular agents | Only to nationals of the State whose court is hearing the case |
| Private process servers | No such concept in Ukrainian procedure |
There is no partial reading here, no ambiguity to argue around. Compare Japan, which objected to 10(b) and (c) but stayed silent on 10(a) — and produced two decades of conflicting US case law on whether postal service is permitted. Ukraine left no such gap.
So: courier, registered post, DHL, a local agent hired to hand over the papers, service on a Ukrainian subsidiary’s director met at a conference in Vienna — none of these is service. They may be perfectly effective at telling your opponent about the claim. That is a different thing from service, and only one of the two survives contact with an enforcement court.
The channel that does work
Requests go to the Ministry of Justice of Ukraine, Department of International Legal Assistance — 13 Horodetskoho Street, Kyiv 01001. Ukrainian courts cannot receive foreign requests directly; a request sent straight to the court will simply be returned.
What the Ministry expects:
- Request in Ukrainian, English or French
- Documents complying with the form, content and language requirements of the applicable treaty
- No fee. Ukraine executes service requests free of charge; if costs do arise, the Ministry notifies the requesting authority and waits for payment before proceeding
Official average time from receipt: two to three months. Plan on longer. HCCH has published no suspension notice for Ukraine, but the official figure assumes ordinary conditions.
What happens after the papers arrive
The internal choreography is worth knowing, because it tells you where a request can stall and what to chase.
The Ministry has fourteen days to check that the request has a proper basis and complies with the treaty as to form, content and language. If nothing is wrong, it goes to the relevant interregional department of the Ministry, which has a further fourteen days to identify the competent court — by subject-matter jurisdiction and by the defendant’s location — and send the request on. These internal steps come from the Ministry’s own instruction on executing treaties concerning service, evidence and recognition of judgments (joint order of the Ministry of Justice and the State Judicial Administration No. 1092/5/54 of 27 June 2008, as amended to 6 April 2023), not from the Convention.
Only then does a court touch it. That court summons the person by court notice to the address in the request, and the summons must state what happens if they refuse the documents or fail to appear.
Service itself is personal. The documents are handed to the individual, their representative, or a representative of the legal entity, against signature — either in a court hearing or by an authorised court officer at the person’s residence, place of stay, place of work, or the company’s registered address. This is Article 501 of the Civil Procedure Code, and Article 370 of the Commercial Procedure Code for commercial matters.
One provision is worth asking about, because nobody applies it unprompted: on the request of the foreign court, procedural steps may be carried out applying the law of another state, provided that does not contradict Ukrainian law. The same articles also let the foreign court ask that its own representatives or the parties attend. Neither happens unless the request says so.
The part foreign counsel do not expect
Here is where Ukrainian procedure is friendlier than it looks.
If the person refuses to accept the documents, the judge or authorised officer marks the refusal on them, and the documents are deemed served. If the person was properly notified of the date, time and place of the hearing at which the documents were to be handed over and does not turn up without good reason, the documents are also deemed served — as of the day of that hearing. Both rules sit in parts 5 and 6 of the same articles.
In other words, a Ukrainian defendant cannot defeat service by declining to open the door. This matters commercially: the evasive defendant is a familiar problem in cross-border litigation, and the Ukrainian channel has an answer to it that many jurisdictions lack.
What comes back to you is a court record — the hearing minutes noting any statements made by the person on receiving the documents, signed by the judge and sealed with the court’s official seal, together with confirmation that the person was notified and any other documents generated along the way. Not an affidavit of service. Counsel expecting a sworn statement in the familiar form sometimes treat the Ukrainian certificate as defective when it is exactly what the system produces.
When a request is refused
The grounds are narrow, and deliberately so. Under the 1954 and 1965 Hague Conventions, execution may be refused only where the requested state considers that compliance would prejudice its sovereignty or security. Ukrainian procedural law restates that ground and adds two more. A request is not accepted for execution if it may prejudice Ukraine’s sovereignty or threaten its national security, if it falls outside the jurisdiction of the court concerned, or if it contradicts Ukrainian law or a treaty binding on Ukraine — Article 500(2) of the Civil Procedure Code for the general courts, Article 369(2) of the Commercial Procedure Code for the commercial courts.
If the request cannot be executed, the court returns it to the foreign court stating the reasons and attaching the documents that support them. You get an explanation, not silence.
One safeguard is worth flagging because it defeats a common assumption. A requested state may not refuse service on the ground that the case belongs to its own exclusive jurisdiction, or that its own law would not permit the proceedings in question. Jurisdiction and mutual legal assistance are separate questions: jurisdiction is for the court seised, assistance is a matter of treaty obligation. Executing a request implies no recognition of the foreign court’s jurisdiction and no undertaking to recognise the eventual judgment — and it is precisely by being served that the defendant acquires the practical ability to contest jurisdiction where the case is pending.
Watch, though, for the bilateral legal assistance treaties. Several of those Ukraine has concluded add a further ground — that assistance would contradict the fundamental principles of the requested state’s legislation. That is a materially wider door than “sovereignty or security”, and where a bilateral treaty applies alongside the Convention, it is the one that decides your case.
Why this is really an enforcement question
Service looks like an administrative chore at the start of a case. It is actually the foundation of the judgment you intend to enforce.
When a foreign judgment is brought to Ukraine for recognition, notice is not a question the court might reach. It is on the list, twice over. The application for leave to enforce must itself include a document certifying that the party against whom the judgment was given, and who did not take part, was duly notified of the date, time and place of the hearing — Article 466(3) of the Civil Procedure Code. And leave is refused where that party was deprived of the opportunity to take part because it was not duly and timely notified — Article 468(2).
So a judgment obtained after courier delivery to a Kyiv office fails twice: you cannot assemble the bundle, and the ground for refusal is there waiting if you do. The objection is a good one, because Ukraine’s Article 10 declarations say so on the face of the treaty record.
Two neighbouring provisions are worth knowing while you are here. The judgment must be presented for enforcement within three years of becoming final (Article 463), and the application goes to the court where the debtor lives or is located — or, failing that, where the debtor’s property is (Article 464).
The cost of doing it correctly is two to three months and no fee. The cost of doing it the fast way is discovered years later, by which time it cannot be fixed.
Questions we are asked
Can I serve a Ukrainian company by email if the contract says notices may be given electronically?
A contractual notice clause governs notices between the parties. It does not convert a claim form into a document validly served under the Convention. Treat the two as unrelated.
We already sent the claim by courier and the defendant has acknowledged receipt. Is that enough?
Actual knowledge and valid service are different things, and it is valid service that an enforcement court examines. Where the timetable still allows, the safer course is to serve again through the Central Authority.
Which language do the documents need to be in?
The Ministry accepts requests in Ukrainian, English or French. Whether the documents to be served must themselves be translated into Ukrainian is a separate question and depends on whether the addressee will accept them voluntarily — confirm the position for your matter before the papers go out.
How long does it really take?
Two to three months is the official figure from the date the Ministry receives the request. Build in more, and start the process before you need it.
What if the defendant simply refuses the documents?
Refusal is recorded and the documents are deemed served. The same applies if the defendant, properly notified, fails to attend the hearing at which service was to take place without good reason.
Our defendant is in custody. Does that stop service?
No. The court sends the documents to the administration of the place of detention, which serves them against signature and returns the receipt and the person’s written explanations to the court without delay.
Does Ukraine charge for executing a request?
No. Service requests are executed free of charge. If expenses arise, you are notified before the work proceeds.
