Sub-Practices

Eight areas of business law.
One in-house perspective.

Our business law practice covers the full range of commercial and corporate legal needs — from ongoing outsourced general counsel support to discrete transactional and regulatory work. Business lawyers in Athens are most useful before a decision is taken, which is why the retainer model exists.

Our Approach to Business Law

We think like the client's
legal department — because we are one.

Most business law advice is written by lawyers who have never run a legal department, managed a budget, or sat in the room when a commercial decision actually gets made. Dionysios Pantazis sits in that room, as General Counsel to a Fortune 50 technology group — managing legal risk across eight countries and seven business lines. The business lawyers in Athens here work to a fixed scope, so the cost of asking is known in advance.

That perspective shapes every piece of advice we give. We do not produce theoretically correct memos that ignore commercial reality. We give the answer an in-house lawyer would actually act on — clear, prioritised, and aware of what a business can realistically absorb in terms of cost, time and risk. Tell us how your legal work arrives and we will propose a structure.

"The best business law advice does not just tell you what the law says. It tells you what to actually do about it — today, with the resources you have."

Our dual qualification in England & Wales and Greece means cross-border commercial matters are handled under a single instruction. Where a contract is governed by English law, the English-law analysis is done here rather than bought in.

Pantazis & Associates is recommended by a number of foreign embassies operating in Greece, including the UK, US and Australian embassies. The firm's lawyers are frequently invited to speak at international legal conferences and symposia, and the firm regularly provides opinions, analysis and commentary to international institutions such as the World Justice Project and the World Bank. In business law as in litigation, the firm has advised on matters that other lawyers read about in textbooks and legal journals — institutional recognition that no marketing budget can buy.

In-house perspective
Led by a sitting Fortune 50 GC
Dionysios Pantazis runs legal operations across eight countries as General Counsel to a Fortune 50 technology group. That experience of running a legal department, not just advising one, defines our approach.
Cross-border capability
England & Wales + Greece, one instruction
Commercial contracts, employment matters and regulatory questions spanning both legal systems advised on in-house — no second firm for the advice, no duplicated cost.
Regulatory depth
GDPR · EU AI Act · NIS2 · DSA
Genuine technical certification and advisory experience across the EU digital regulatory landscape — not generic compliance boilerplate.
Practical structuring
Retainer, project, or one-off — your choice
From an ongoing Outsourced GC retainer to a single discrete transaction, we structure the engagement around what your business actually needs.

How We Work

Structured to fit
how your business actually operates.

STEP 01
Initial Scoping
A conversation about your business, your legal needs and the volume and nature of matters you expect to arise. No assumption about the right engagement structure until we understand your situation.
STEP 02
Engagement Structure
We propose the structure that fits — an ongoing Outsourced GC retainer, a project-based engagement for a specific transaction, or a one-off instruction for a discrete matter.
STEP 03
Delivery
Direct access to the lawyer handling your matter. Clear, prioritised advice that reflects commercial reality, not just legal theory. Response times that match the urgency of your business.
STEP 04
Ongoing Relationship
Where the relationship continues — through a retainer or repeat instructions — your lawyer builds deep familiarity with your business, making every subsequent piece of advice faster and more precisely calibrated.
