Independent Legal Opinions on Ukrainian Law
A structured aviation lease requires a Ukrainian law opinion confirming that the security assignment will be recognized under Ukrainian law. An international lender needs a capacity opinion before disbursement — confirming that the Ukrainian borrower has the corporate authority to enter into the facility agreement and that the obligations are enforceable. A London arbitration team needs an independent opinion on whether a contractual penalty clause is enforceable under Ukrainian mandatory rules.
Independent legal opinions on Ukrainian law are formal professional statements issued by a qualified Ukrainian lawyer, confirming specific legal conclusions that the recipient is entitled to rely upon. Jurvneshservice issues independent legal opinions for international law firms, transaction counsel, lenders, lessors, and investors. This practice forms part of our broader offering in legal opinions and expert witness reports.
What a legal opinion covers
A legal opinion states conclusions on defined questions of Ukrainian law, based on stated assumptions and subject to stated qualifications. The opinion-giver assumes professional responsibility for the accuracy of the conclusions within the stated scope.
- Assumptions — factual premises accepted without independent verification (e.g., authenticity of signatures, accuracy of corporate registers)
- Qualifications — limitations on the opinion (e.g., bankruptcy risk, future legislative changes, court discretion)
- Conclusions — definitive statements on the legal questions addressed (e.g., “the obligations are valid and enforceable under Ukrainian law”)
- Reliance — who may rely on the opinion (typically the addressee, their successors and assigns)
This practice covers independent legal opinions — formal professional documents for transactions, due diligence, and dispute strategy. For expert evidence submitted in court or arbitration proceedings (written reports, oral testimony, cross-examination) → Expert Witness on Ukrainian Law.

Work algorithm
We issue legal opinions as a structured engagement — from scope definition through document review to executed delivery.
Step 1 — Scope and assumptions. We review the instruction letter, identify the legal questions, and agree on scope. We define assumptions (factual premises accepted without verification), qualifications (limitations), and addressees (who may rely on the opinion).
Step 2 — Document review. We review transaction documents, corporate records, and other relevant materials. For transaction opinions — facility agreements, security documents, resolutions, constitutional documents. For dispute-related opinions — contracts, court decisions, procedural history.
Step 3 — Legal analysis. Comprehensive legal research — legislation, judicial practice, doctrinal sources. Where the law is unsettled or practice is inconsistent, we disclose this and provide our reasoned conclusion.
Step 4 — Draft opinion. We prepare the draft in the format required by the instructing party — following international market practice for opinion letters. Date, addressee, scope, assumptions, qualifications, analysis, and conclusions.
Step 5 — Review and finalization. We circulate the draft for comments, address feedback, finalize, and issue in executed form. For transaction closings, we coordinate issuance with the closing mechanics.

FAQ: Independent Legal Opinions on Ukrainian Law
What is the difference between a legal opinion and an expert report?
A legal opinion is a professional document issued outside court proceedings — it confirms specific legal conclusions that the addressee is entitled to rely upon. An expert report is evidence submitted in court or arbitration to assist the tribunal. Both require professional responsibility, but opinions support transactions and strategy, while expert reports support adjudication.
Who can rely on your legal opinion?
The opinion is addressed to the instructing party and states who may rely on it. Typically, reliance extends to the addressee and, where specified, their successors and assigns, co-lenders, or other transaction parties. We do not issue opinions for general reliance — each opinion names its permitted reliance parties.
In what format do you issue opinions?
We follow international market practice — a formal letter on firm letterhead, signed by the opinion-giver, addressed to the specified parties. For aviation and structured finance, we follow the format customary in those markets. We can adapt the format to match the template required by transaction counsel.
How long does it take to issue a legal opinion?
Standard transaction opinions require one to two weeks from receipt of final documents and corporate records. Complex opinions (structured finance, multi-entity due diligence) may require two to three weeks. We accommodate urgent timelines and have issued opinions within days when required by closing schedules.
What does a legal opinion cost?
Fees depend on the type and complexity of the opinion, the number of legal questions, and the volume of documents. We provide a fixed-fee quote after reviewing the instruction letter. For recurring engagements (e.g., series of aircraft lease opinions), we offer framework arrangements.
Can you issue opinions in English?
Yes. All our opinions are issued in English as the primary language. Where the transaction documents or the instructing party require a Ukrainian language version, we provide that as well.
