Dr. Marcus A. Hosser, TEP

Dr. Marcus A. Hosser, TEP, is the owner of DR. HOSSER Rechtsanwalt, an inheritance and tax law practice with offices in Karlsruhe and Mannheim, which has been named Inheritance Law Firm of the Year in Germany at the Corporate INTL Global Awards 2025. A certified inheritance law specialist (Fachanwalt für Erbrecht) and certified tax law specialist (Fachanwalt für Steuerrecht), Dr. Hosser also holds the internationally recognised Trust and Estate Practitioner (TEP) designation, marking him out as an adviser equipped for cross-border succession as well as domestic estate planning.

The firm concentrates on the full spectrum of inheritance matters, from international succession planning and estate administration to business succession arranged during a client's lifetime or on death. A significant part of the practice is dedicated to cross-border inheritance cases involving international clients, including estate settlement for foreign clients with assets or family connections in Germany. This international focus is reinforced by Dr. Hosser's TEP membership and his fluency in the interaction between succession law and tax.

That combination of inheritance and tax expertise is central to the firm's offering. Inheritance and gift tax, both national and international, sits at the heart of most succession decisions, and Dr. Hosser's dual specialisation allows him to weigh the legal structure of a will, gift or succession plan against its tax consequences in a single, coordinated piece of advice. As the firm puts it, clients receive personal, individualised counsel with particular attention paid to tax considerations — an approach that helps families and business owners preserve wealth and avoid unnecessary friction between generations.

Dr. Hosser's credentials extend beyond his two specialist bar qualifications. He is a certified consultant for business succession (zentUma) and a certified executor (DVEV), reflecting the practical roles he takes on for clients: not only planning how assets should pass, but also administering estates and steering the orderly handover of family businesses. Business succession in particular demands a careful blend of company law, family dynamics and tax planning, and the firm is structured to address all three.

The practice serves middle-market businesses, private clients and entrepreneurs, and prides itself on going beyond purely legal questions to champion its clients' interests actively and present workable routes to their goals. This is especially valuable in cross-border cases, where differing national rules on succession, forced heirship and taxation can create traps for the unwary. Dr. Hosser's role is to anticipate those complications and to design arrangements that hold good across jurisdictions.

Recognition as Inheritance Law Firm of the Year in Germany underlines the standing Dr. Hosser has established in a field that calls for both technical precision and personal sensitivity. Succession touches on family, business and legacy, and clients need an adviser who can handle the emotional as well as the legal and fiscal dimensions of passing on wealth. With offices in Karlsruhe and Mannheim and a practice built on certified expertise in both inheritance and tax law, DR. HOSSER Rechtsanwalt offers exactly that: careful, tax-aware and internationally capable guidance for those planning ahead or managing an estate already in hand.
