‘I always appreciate the friendly and efficient responsiveness of the Aigner team to my requests. Over the last twelve years I had in several cases – some of them in court – the opportunity to evaluate and assess their strengths in supporting me.’

‘Very focused on each client, always looking for special solutions, perseverance in each case, short answer time.’

‘Very reliable.’

‘I highly appreciate Aigner Lehner Zuschin + Partner for its great professional competence, goal-oriented approach and many years of experience in the field of commercial litigation. The latest developments in case law and the status of other pending proceedings are presented comprehensively but understandably, strengths and weaknesses of the legal position are shown in a very clear manner. Prudent legal caution is applied, also with regard to the client’s litigation risk. I also liked the initiative in processing and reviewing the facts of the case. As a result of this not only the legal thinking but also the professional understanding of the subject matter of the case is excellent.’

‘All team members I worked with are very dedicated to their clients. Johannes Lehner combines his outstanding litigation expertise with strong knowledge in real estate law and strong government know-how. He takes personal care of the cases in all aspects. Lukas Aigner is well known in Austria.’

‘Johannes Lehner is very competent and helpful.’

‘Johannes Lehner: digs deep when handling cases, innovative approaches for litigation.’

‘Lukas Aigner: founder of the chambers, but still accessible for every customer and very well informed about the cases.’
