Through his earlier work for various museums in Freiburg and Hamburg, Alexander Unverzagt has for decades had close personal contacts with artists, exhibition organisers, organisers of art events and art fairs, art educators, but also with museums, agents and auction houses, art dealers, gallery owners, restorers, art advisers and art collectors.

Today, we advise and act for (often only in the background) a significant number of collectors in relation both to auction house purchases and their reversal, but equally for museums in respect to assessing their rights in original works or photographs.  Increasingly, questions of copyright ownership and liability for infringement are coming into play, which are then resolved in the context of expert opinions.

Legal opinions on the subject of an "original" or "imitation" and of the use of "old works of art in the digital era" are drafted and transmitted with all the discretion so necessary in this field.

With ever greater frequency we are being called upon to assist where various civil law liability risks arise in relation to art events.

Numerous talks delivered to the Association of Art Restorers on the subjection of restoration and copyright and to insurers of works of arts ensure that our technical legal advice to clients is underpinned with broad practical experience.
