TILP Rechtsanwaltsgesellschaft mbH ("TILP"), with its office in Tuebingen, is one of Germany's leading and most experienced law firms with an exclusive focus on effectively protecting the interests of aggrieved investors since 1994, whether they are institutional clients, family offices or private investors.

The media and even their competitors share this opinion: For many years now TILP is considered as one of the absolute market leaders in the fields of banking law and capital market law in Germany. The publisher NOMOS in its "Handbuch der Kanzleien 2014" (Handbook of German Law Firms 2014) calls TILP " ‘the’ leading capital market law firm”. The handbook for corporate law firms 2014/2015 of JUVE, the leading legal expert publication, evaluates TILP as one of the top leading law firms in the area of capital market litigation for over ten years. According to publications of JUVE, TILP is "one of the leading law firms representing both, institutional and private investors in banking and capital market law matters ... which ranks among the top tier addresses for years now and ... which decisively has shaped this field of law". Moreover, competitors attest TILP an “archetype function and high professional competence". In its annual handbook 2016/2017 the legal market journal JUVE has ranked TILP as the nation's only boutique law firm for financial disputes and securities litigation in the absolute top-tier for the category "Commercial Litigation and Liability".

TILP’s practice has designated expertise in the area of national and international collective redress in particular regarding national collective redress mechanisms under the German Capital Market Model Claims Act (Kapitalanleger-Musterverfahrensgesetz, KapMuG). In November 2012, a reform of this Act came into force for which Andreas Tilp was one of the nine experts by the Committee on Legal Affairs of the German Federal Parliament. In October 2014 TILP has won the "biggest court proceeding in German economic history" (DER SPIEGEL as of 3 March 2008) before the Federal Court of Justice (Bundesgerichtshof) in the model case proceedings against Deutsche Telekom AG regarding DT3. He also won the proceedings for the model plaintiff in the model case proceedings against Hypo Real Estate Holding AG (HRE) before the Higher Regional Court (Oberlandesgericht) of Munich. The Frankfurter Allgemeine Zeitung called Andreas Tilp “an expert for mass claims” (December 11, 2014) and “Mister KapMuG” (September 18, 2016).
Since 1994, TILP has successfully acted in the fields of banking law, stock market law, investment law and capital market law. Since then, the law firm has effectuated about more than 150 decisions of the German Federal Court of Justice (Bundesgerichtshof) and the German Federal Constitutional Court (Bundesverfassungsgericht) which were of fundamental importance for investor rights in Germany - the journal FOCUS referred to the German Federal Court of Justice's decision on hidden commissions charged to investors (the so called "kickback decision"), which was argued by TILP in December 2006, as a "sensational decision" (edition 11/2007). For consumer advocates this decision constituted a "major milestone in consumer protection".

The business magazine CAPITAL calls Andreas Tilp "an established force ...considered one of the most experienced attorneys..." (edition 17/2006). For Sueddeutsche Zeitung, he is "the Nestor among the investor protection attorneys" (25 November 2008). The journal DER SPIEGEL refers to him as an "international experienced investors' attorney" (edition 31/2008). According to the evaluation of the Frankfurter Allgemeine Sonntagszeitung, he is "probably the best known attorney in this country" (16 August 2009). Andreas Tilp is vice chairman of the legislative committee for banking and capital market law of the German Bar Association (Deutscher AnwaltVerein) and is a vehement advocate for the interests of aggrieved investors for example at the roundtable discussions and hearings of the German Bundestag and of the European Commission. He acted inter alia as an expert for the Corporate Governance commission of the German government regarding the investor protection and functionality improvement act, the AIFM directive and for the first financial market reform act.

TILP is partner of the law firms TILP PLLC, New York as well as TILP Litigation Lda & Comandita (ZFDM), Funchal/Madeira, which are specialized on the international representation of institutional investors and entities on the field of capital market and antitrust law.
