How to Choose an M&A Lawyer in Poland (2026): a Practical Checklist for Foreign Buyers

Choosing the right M&A lawyer Poland-based advisers can make or break a cross-border acquisition in 2026, and the stakes have rarely been higher for foreign buyers. A wave of regulatory change, reform of Polish holding-company rules, foreign direct investment (FDI) screening, the application of EU foreign-subsidy checks to inbound deals, evolving merger-control practice before the competition authority, and labour-law adjustments affecting post-closing integration, has reshaped what “good counsel” means for a Polish target. For private equity sponsors, strategic acquirers and in-house M&A teams, the selection decision is no longer just about corporate transactional skill; it is about regulator-savvy, cross-border coordination and the ability to hold a timeline together under multiple approval regimes.

This guide gives you a practical, decision-stage checklist to evaluate and engage the right advisers, backed by interview questions, a comparison of local versus international counsel, and realistic guidance on fees and engagement terms. Use it alongside the M&A lawyers Poland, directory to shortlist and match candidates efficiently.

1. Why choosing the right Polish M&A lawyer matters in 2026

The 2026 regulatory environment in Poland involves multiple, often overlapping, review regimes that directly affect deal timing, conditions precedent and the structure of your acquisition agreement. A misjudged filing strategy, or a failure to identify a screening trigger early, can add months to a transaction, force renegotiation of closing conditions, or expose the buyer to unwind risk. This is precisely why an experienced m&a lawyer Poland practitioner earns their fee: not simply by drafting a share purchase agreement, but by mapping the regulatory approval path before signing and building it into the deal calendar.

Several changes converge to raise the bar for counsel selection. Reform of the holding-law framework within the Polish Commercial Companies Code affects group structures and intra-group relationships that acquirers frequently rely on. FDI screening under Polish legislation broadens the range of transactions requiring notification to the relevant Polish authority for certain protected entities and sectors. At EU level, the Foreign Subsidies Regulation adds a further notification layer where foreign financial contributions meet defined thresholds. Merger-control practice before the President of the Office of Competition and Consumer Protection (UOKiK) continues to develop, and labour-law adjustments affect employment transfers and works-council obligations during integration.

The consequence for buyers is clear: the right adviser must understand how these regimes interact and sequence, not just each one in isolation.

Quick list of 2026 regulatory hooks

• FDI screening. Certain deals fall within notification requirements, with control exercised by the relevant Polish authority over protected entities and strategic sectors.
• EU foreign-subsidy checks. Inbound acquisitions may require notification under the EU Foreign Subsidies Regulation in parallel with national filings.
• Merger control before UOKiK. Evolving practice and thresholds mean early antitrust analysis is essential for cross-border deals.
• Holding-law and labour changes. Corporate group and employment-transfer rules affect structuring and post-closing integration risk.

2. Quick checklist: 10 must-haves when selecting counsel

Before you run a full selection process, use this ten-point checklist to screen candidates. Each item includes a quick way to verify it, so you can separate genuine specialists from generalists marketing themselves as M&A advisers.

1. Proven FDI screening experience. Ask for anonymised examples of screened deals and the sectors involved. Verify by requesting the role the firm played and the outcome.
2. Merger-control track record. Confirm clearances obtained before UOKiK and, where relevant, the European Commission. Ask about second-phase (in-depth) experience.
3. Cross-border coordination capability. Establish how the firm coordinates with your home-jurisdiction counsel, tax advisers and lenders.
4. Relevant sector experience. Regulated sectors (energy, defence, telecoms, finance) demand specific licensing knowledge, confirm it exists in-house.
5. Post-closing integration advice. Ask whether the team advises on employment transfers, works councils and integration, not just signing.
6. Language and staffing plan. Confirm who does the Polish-language filings, who leads negotiation, and the seniority mix on the team.
7. Independent references. Request two or three buyer-side references for comparable deals and actually contact them.
8. Sample engagement terms. A firm that can share a clear engagement letter template early signals maturity and transparency.
9. Fee transparency. Insist on a written fee estimate with assumptions and change triggers, not a vague hourly indication.
10. Availability for closing. Confirm the named partner and key associates are available across your target timeline, including likely regulatory delays.

How to score candidates quickly

Assign each of the ten items a score from 1 to 5, then weight the three most important criteria for your deal (typically FDI, merger control and cross-border coordination) at double value. A candidate that scores strongly on transactional skill but poorly on regulatory experience should not automatically win a regulated-sector, high-value deal. This simple weighted scorecard forces you to prioritise the competencies that actually protect your transaction in 2026.

3. Regulatory and sector experience to prioritise

The single biggest differentiator among Polish M&A advisers in 2026 is regulatory depth. Corporate drafting is important, but it is the regulatory analysis, done early and accurately, that determines whether your deal closes on time. When you assess any prospective m&a lawyer Poland candidate, probe the following four areas in detail.

Merger control (UOKiK and EU), what to ask, thresholds, timing

Poland operates a formal merger-control regime administered by the President of the Office of Competition and Consumer Protection (UOKiK) under the Act on Competition and Consumer Protection, with notification obligations and defined review phases. For deals with a wider European dimension, the EU Merger Regulation (Council Regulation (EC) No 139/2004) governs whether the transaction is reviewed by the European Commission instead of, or in addition to, national authorities, together with the applicable referral rules. Ask your candidate to walk you through, at a high level, how they would determine which regime applies to your target and how they approach pre-notification.

Because thresholds and procedural timelines are subject to current UOKiK guidance, insist that any timeline the firm gives you is stated as “typical” and confirmed against the authority’s published practice. A strong adviser will build the review period into the conditions precedent and long-stop date from the outset.

FDI screening and foreign-subsidy checks, triggers and counsel role

FDI screening in Poland is governed by national legislation with oversight by the designated control authority for protected entities and strategic sectors, and the government provides official descriptions of the screening process and relevant procedures. Your counsel’s role is to identify whether the target’s activity or the buyer’s profile triggers a notification, prepare the filing, and manage the interaction with the reviewing authority. Separately, the EU Foreign Subsidies Regulation may require notification where foreign financial contributions and deal values meet the relevant thresholds, a check that operates alongside, not instead of, national filings. Ask candidates how they run these two analyses in parallel and how they sequence them against merger control.

The ability to coordinate three potential clearance regimes is a hallmark of genuine cross-border M&A Poland expertise.

Labour and employment, post-closing integration risk

The Polish Labour Code governs employment relationships and, in the M&A context, the transfer of employees on a business or asset acquisition. Labour-law rules carry implications for employment transfers, works-council information and consultation, and collective-bargaining arrangements during integration. A buyer that underestimates these obligations can face disruption and cost after closing. Confirm that your prospective adviser can flag labour risk during due diligence and design an integration plan that respects consultation requirements and preserves workforce continuity.

Sectoral licences, energy, defence, telecoms and beyond

Regulated sectors frequently require additional approvals or licence transfers that sit on top of general merger control and FDI screening. Energy assets, defence-related businesses and telecoms operators are common examples. Ask candidates whether they have handled licence continuity and sector-regulator engagement for comparable targets. Missing a sectoral approval can be as damaging to a deal timetable as missing a competition filing.

Do foreign buyers need local Polish counsel? In almost all cases, yes, local filings, notarial requirements and regulator interaction are handled most reliably by admitted Polish practitioners. The practical question is usually whether to instruct a Polish firm directly or to work through an international firm with local capability, which is addressed in the next section.

4. Local counsel vs international firm: which to choose for your m&a lawyer Poland engagement?

One of the most consequential decisions foreign buyers make is whether to instruct an independent Polish firm, a large international firm with a Warsaw presence, or a coordinated team combining both. There is no universally correct answer; the right choice depends on deal size, complexity, regulatory intensity and how much cross-border coordination you need.

When to use local boutique or independent counsel

Independent Polish counsel typically offer deep, practical knowledge of local regulator practice, faster on-the-ground handling of FDI and sectoral approvals, and more flexible, generally lower-cost fee models. For smaller or more localised deals, and particularly for regulatory-heavy matters where day-to-day interaction with UOKiK or a sectoral regulator is central, a strong local firm can outperform a larger international team. The trade-off is that you will usually need trusted co-counsel in your home jurisdiction to coordinate financing, cross-border tax and multi-jurisdictional documentation.

When to use a large international firm or coordinated team

An international firm with a Warsaw office can provide single-firm coordination across jurisdictions, multilingual teams, and the scale needed for complex financing and multi-jurisdictional structures. For large, high-value cross-border transactions with parallel filings in several countries, this coordination can justify the higher rates and overhead. Many buyers adopt a hybrid model: lead international counsel for overall deal management, with a specialist Polish firm handling local filings and regulator interaction.

How do I find the right M&A lawyer in Poland? Start by defining your deal profile against the table above, then run a structured selection process, the subject of the next section, rather than relying on reputation alone. A dedicated resource comparing local versus international M&A counsel in Poland can help you refine the decision once you have shortlisted candidates.

5. How to run the counsel selection process

A disciplined process protects you from choosing on the basis of brand or a single impressive pitch. The recommended sequence is: prepare a short request for proposal (RFP), shortlist three or four firms, run structured interviews, check references, negotiate engagement terms and onboard the winner. Done properly, this takes days rather than weeks and dramatically improves the quality of your final decision.

RFP template, what to ask

Keep the RFP tight and specific to your deal. At minimum, request the following from each candidate:

• Scope confirmation. Their understanding of the transaction, the target sector and the regulatory regimes likely to apply.
• Team CVs. Named partner, senior associate and support, with relevant deal experience for each.
• Timing. A realistic timeline including regulatory review periods, stated as typical and to be confirmed.
• Fee estimate. A written estimate by phase, with assumptions and change triggers.
• Conflict checks. Confirmation that conflict clearance has been run and any waivers required.
• Regulatory approach. How they will run merger control, FDI screening and any foreign-subsidy analysis in parallel.

Interview questions, tailored to cross-border and regulatory risk

Interview your shortlist against a consistent set of questions so you can compare like with like. The following twelve questions surface the competencies that matter most for a Polish target in 2026, with a note on what a strong answer looks like.

1. Which regulatory regimes do you expect to apply to this deal, and why? A strong answer maps merger control, FDI and foreign-subsidy checks specifically to your target.
2. How would you sequence the required filings? Look for a clear view on parallel versus sequential filings and long-stop-date implications.
3. What is your recent experience with UOKiK notifications? Expect concrete, anonymised examples and in-depth (second-phase) experience where relevant.
4. Have you handled FDI screening for a comparable target? The ideal answer references the sector and the applicable control process.
5. How do you assess whether the EU Foreign Subsidies Regulation applies? Look for a threshold-based analysis rather than a vague acknowledgement.
6. Who will do the Polish-language filings and notarial work? A clear staffing answer confirms local capability.
7. How do you coordinate with our home-jurisdiction counsel and lenders? Expect a defined communication and document-management protocol.
8. What labour-law risks do you anticipate on integration? A strong answer addresses employment transfers and consultation obligations under the Labour Code.
9. What are the key conditions precedent you would recommend? Look for regulatory clearances built into the deal structure.
10. How do you charge, and what could move the estimate? Expect transparency on fee model and change triggers.
11. Who is accountable if the named partner becomes unavailable? A credible succession plan matters for closing certainty.
12. Can you provide two buyer-side references for similar deals? A confident specialist will offer references without hesitation.

Red flags to watch for

• No demonstrable regulatory experience. Strong corporate drafting cannot substitute for merger-control and FDI screening depth in 2026.
• No named partner on the file. Be wary of proposals that pitch a brand but will not commit a specific senior lawyer.
• Vague or open-ended fees. An unwillingness to provide a written estimate with assumptions signals future disputes.
• No references, or reluctance to provide them. Comparable-deal references are a basic and reasonable request.
• Unrealistic timelines. A firm that ignores regulatory review periods to win the pitch is not protecting your interests.

Shortlist scoring template

Copy the following columns into a spreadsheet and score each candidate from 1 to 5: regulatory experience (FDI), regulatory experience (merger control), sector knowledge, cross-border coordination, team seniority and availability, fee transparency, references, and overall communication quality. Weight the top three criteria for your deal at double value and total the scores. This gives you a defensible, comparable basis for the final decision.

What should I ask an M&A lawyer before hiring them for a cross-border deal? Use the twelve interview questions above as your baseline, adapting the sector-specific items to your target. The quality of the answers, especially on regulatory sequencing and staffing, is usually more revealing than the firm’s marketing materials.

6. Engagement terms, fee structures and cost expectations in Poland

Fee models in Poland are broadly comparable to other European markets, but there are local nuances worth understanding before you negotiate. The common structures are:

• Hourly rates. The default for complex or unpredictable matters, with rates varying by seniority and firm type.
• Blended rates. A single average rate across the team, offering simplicity and cost predictability.
• Capped fees. An hourly arrangement with a ceiling, giving the buyer downside protection while preserving flexibility.
• Fixed or phased fees. Common for defined deliverables such as due diligence or a specific filing.
• Retainers. Used for ongoing advisory relationships or to secure team availability.

Pure percentage-of-deal or success-only arrangements are less common in Poland than in some markets, and buyers should note that professional-conduct rules for advocates (adwokat) and legal advisors (radca prawny) constrain certain fee arrangements. Where any success element is proposed, confirm it is permissible under the applicable rules of professional conduct before relying on it. VAT will generally apply to legal fees and should be built into your budget.

Negotiation pointers and sample clauses

When negotiating the engagement letter, focus on the terms that protect certainty and control cost:

• Scope definition. Precisely describe the transaction, the phases covered and any exclusions.
• Fee-change triggers. Specify the circumstances (scope expansion, additional filings, in-depth review) that permit a revised estimate.
• Staffing commitments. Name the partner and key associates and require notice of any change.
• Work reporting. Require regular narrative billing and budget-versus-actual reporting.
• Third-party coordination. Set out how the firm will work with your home counsel and other advisers.
• Liability limitation. Agree a limitation of liability appropriate to the deal value, subject to applicable rules.

A simple sample fee clause might provide that fees are charged on a phased fixed-fee basis for due diligence and documentation, with a capped hourly arrangement for the regulatory clearance phase, and that any change to the estimate requires the buyer’s prior written approval. A short liability note might record that the firm’s aggregate liability is limited to a defined sum, subject to the mandatory professional and legal rules that cannot be excluded. For deeper guidance, a dedicated resource on engagement letters and fee structures for M&A in Poland is a useful companion to this section.

7. Due diligence, closing and post-closing support, what counsel should deliver

A capable adviser delivers value across the whole deal lifecycle, not just at signing. Expect a phased scope: preliminary due diligence to identify red-flag issues; focused regulatory due diligence covering merger control, FDI and sectoral licensing; contract negotiation and redlines; a closing checklist; handling of escrow or client-account arrangements where used; and post-closing integration support including employment transfers under the Labour Code. Corporate steps such as share transfers and form requirements are governed by the Polish Commercial Companies Code, and your counsel should manage these mechanics precisely, including any notarial requirements. Crucially, counsel should own the regulatory filings and notifications, to UOKiK, the FDI control authority and any sectoral registry, and keep them synchronised with the commercial timetable.

Typical timelines and SLA expectations for Polish filings

Regulatory timelines vary by matter and are subject to current authority practice, so any figures should be treated as typical and confirmed by your adviser. What you can reasonably expect is a clear, written filing plan with target dates, defined responsibilities for each filing, and prompt escalation if a review moves to an extended phase. Agree service-level expectations for turnaround on due diligence reports, contract mark-ups and status updates, so that regulatory review periods, which you cannot control, are not compounded by avoidable delays in the adviser’s own workflow.

8. Hiring checklist, scorecard and next steps

To convert this guidance into action, follow a repeatable sequence: define your deal profile, choose between local, international or hybrid counsel, issue a focused RFP, shortlist three or four firms, run structured interviews using the twelve questions above, check references, score candidates on your weighted template, negotiate engagement terms, and onboard with an agreed filing plan and early due-diligence instructions. Instruct your chosen adviser to begin regulatory triage immediately, so that any merger-control, FDI or foreign-subsidy triggers are identified before you commit to a signing date.

When you are ready to shortlist, the M&A lawyers Poland, directory lets you match specialist candidates against your deal profile. You can also review the expert author profile for practical cross-border and regulatory experience relevant to inbound investment into Poland and the wider CEE region.

Conclusion

Selecting the right m&a lawyer Poland team in 2026 is fundamentally a regulatory-risk decision as much as a transactional one. The convergence of FDI screening, EU foreign-subsidy checks, evolving merger-control practice, holding-law reform and labour-law change means that the advisers who protect your deal are those who can map, sequence and manage multiple approval regimes before you commit to a timeline. Use the ten-point checklist, the twelve interview questions and the weighted scorecard in this guide to run a disciplined selection process, and decide deliberately between local, international or hybrid counsel based on your deal profile. When you are ready to move, begin with structured triage of the regulatory triggers and shortlist specialist candidates through the resources linked above.
