Oppenheim Law Firm Budapest

Not your average law firm

Oppenheim offers all the benefits of big law, but without the hassles.

We are one of Hungary's largest law firms, but we all work on the same floor and know each other.

We have been around for over 30 years, but we are still interested in you: what makes you tick, what you want to achieve, what makes you happy.

Our lawyers are highly qualified and experienced, but they are also real people who will help you solve your legal problems in a way that really suits you.

We are a Hungarian law firm, but we have been working for international clients for over three decades.

We have our processes, but we are happy to throw away the cookie-cutter, roll up our sleeves and come up with something we have made especially for you.

So if you want a lawyer who does an excellent job AND can talk about flying planes, spotting trains, collecting coins, making wine, writing literature, or failing as a musician, you have come to the right place!
