In-depth knowledge of the market, the ability to quickly build networks – also internationally – and to use them, great flexibility to adapt to changing situations, pragmatic access to new challenges, flat hierarchies.

The practice is highly specialised; they are not trying to cover everything/ not trying to pretend to be experts in everything – if some additional knowledge is needed, it will be brought in from external experts and will be integrated. I very much appreciate this approach!

Lukas Aigner is so passionate and committed to what he is doing! His exceptional and wide-ranging legal expertise and economic knowledge makes him outstanding. With his customer-orientated and solution-driven work style, it is a great pleasure to work with him.’

The firm has extensive experience in resolving disputes before ordinary courts as well as arbitral tribunals.

Due to its vast litigating experience, the firm’s competence in developing efficient strategies to enforce or defend claims is especially noteworthy. Consequently, the economic aspects are always given great consideration in the decision-making process and strategy, which is naturally of great importance from the client’s point of view.

The team is very quick in responding and attorneys are very easily accessible, which stands out to me. Further, the team is in constant consultation with us to find the best solution and they go the extra mile in this regard.

Complete honesty, even when they don’t instantly know the answer, they tell you so and get to work to figure out the case as soon as possible. Also, when they aren’t experts in a specific field, they refer you to colleagues who are.

The matters of our firm are mainly handled by Lukas Aigner and Johannes Lehner. Lukas Aigner has profound experience concerning the enforcement of contentious claims, especially in capital market law cases. Johannes Lehner has a broad background in commercial law, so that both stand out as a team with remarkable assertiveness in litigation proceedings.

My collaboration with Brandl & Talos has already been going on for several years. These lawyers know and understand business as much as they do law, and act to address the economic, capital markets, tax as well as corporate aspects of the case.
