Srečo Jadek

1958 – Establishment of Andrej Jadek Law Office
After a short period of working as a judge, Andrej Jadek established his own Law Office. As was customary in Central Europe until the early nineties of the last century, the Law Office operated as a general practice, covering all areas of criminal, civil and commercial law, and offering its services in both commercial and civil cases. It asserted itself mostly as an excellent service in resolving contentious matters.

1983 – Temporary takeover of the Office by Attorney Milosav Miladinović
Following Andrej Jadek’s death, the Office was temporarily taken over by the attorney Milosav Miladinovič, whilst Srečo Jadek was employed as attorney trainee.

1984 – Continuation of the Office as Srečo Jadek Law Office
After registering as an attorney with Slovenia’s Bar Association, Srečo Jadek resumed working on the files of the Andrej Jadek Law Office and continued his father’s general practice and specialization in resolving matters in dispute, but the focus of his work gradually shifted towards commercial law. During this period the Law Office asserted itself, as one of the firsts in Slovenia, in the area of insolvency law, and Srečo Jadek became a bankruptcy trustee in one of the biggest bankruptcy cases in the country.

1990 – Establishment of Pavle Pensa Law Office
In accordance with his previous work as a Research fellow at the Centre of International Cooperation and Development, specialising in international economic and business relationships, Pavle Pensa focused his attention on business law, especially in foreign investments.

Jadek & Pensa Law Office was established as a partnership. The aim of the merger was an establishment of a Law Office, which would specialise in commercial law, offering high quality service both in contentious matters, as well as in protecting clients’ interests in transactions and in regular business operations. Growing complexity of commercial litigation and international business demanded team work of an increasing number of qualified attorneys. Many excellent young attorneys started their legal careers as trainees and attorney candidates with Jadek & Pensa Law Office.

2001 – Transformation into Jadek & Pensa Law Firm
A growing number of clients, the striving after high quality team work, the need for material funds required for a larger group of attorneys, and the need for specialisation have led to the transformation from a two attorney Law Office to a Law Firm, open for new attorneys to join.

He is the author of several articles and articles, he lectured at various seminars, and his goal in life is to solve their problems. Problems often begin with law, and the solution is always sought broader than merely in legal norms. Already Cicero said that the highest law can be the biggest injustice, so the problems need to be addressed in a comprehensive and cum grano salis (with a touch of salt). Solving legal problems is often associated with a lot of nerves, stress, and, last but not least, cost, so the wisdom of alignment and relaxation at the right time is sometimes the greatest victory!
