For certificates, confirmations or oral statements of third parties (artists, estate administrators, respective experts, collectors, dealers) the exhibitors are liable independently, insofar as reference is made to them. The state of preservation is not mentioned consistently in texts, so that missing information also does not constitute a conditional agreement.
4. Provenance and authentication
4.1 Research into the provenance of a work of art is usually based on complex work that often lasts for long time. It concerns works and themes that date back decades or centuries. Often the only sources that provide information are written by third parties, whose presentation and assessment of the events can also be doubtful according to current knowledge. Nevertheless based on the results of an investigation in view of the exceptional care combined with in-depth existing expertise. Therefore:
4.2 The subject of the investigation is exclusively the question of the authenticity of a work of art. The question of origin is taken into account in this context, but is not decisive. There will be no liability adopted for: the accuracy of the facts, analyzes presented in the sources, conclusions and reviews, the completeness of the research and evaluation of the source material, the analyzes drawn from the sources in the course of the research and conclusions and the findings related to the subject of the report and their coming about and the authenticity of the work of art and the correctness of its attribution to a specific artist.
It is also pointed out that the assessment of an examined work of art cannot always be based on the original and that photographs can be used for verification.
4.3 The investigation report is based on the sources available to the expert at the time of its creation. It is expressly pointed out that the discovery of new source material, which could lead to a re-evaluation of the results found, cannot be ruled out.
4.4 The respective investigation report makes no statement on legal claims and legal positions. A legal review is not binding. No liability is assumed for conclusions drawn by the addressee(s) or third parties from an investigation report.

In case of a claimed or proven insignificant value, a monthly flat rate can be agreed, from 50 EUR net up per artwork. Insurance fee under existing collective insurance policies may but must not be included. In all other cases the client is responsible to hold himself an all risks insurance. This also applies to any necessary additional security arrangements. In no case ArtExpert, experts resp. authorized employees will be responsible in the absence of intentional liability despite proper storage; this applies in particular to any kind of loss.
5.3 Unless otherwise agreed and proven before the event of damage, both parties agree that only the material value shall be considered in case of loss or damage. Upon termination of the contractual relationship or in case of non-fulfillment of the contract by the client, the contractor is released from a duty to keep records and assumes no liability except in the case of intent. Insofar as a liability should be determined, it is agreed that the sum of liability is limited to a maximum of the value determined in advance after written expert examination and submission of the original documents. Insofar as the client should claim further liability, in particular a specific value, this remains reserved for an individual written framework agreement or an additional written individual agreement. In any case, the client is subject to proof in relation to the claimed value. Insofar as further costs arise in the course of storage (for example, special security preparations, transport, insurance), these have to be paid by the client in the course of normal business transactions or in the amount of the proven costs. ArtExpert I Network reserves the right, however, to refuse such an order, if a transfer of liability is desired.
5.4. The client declares that he has the legal ownership of the delivered items. An assignment requires legal ownership. insofar as the client is not the owner, he confirms that he is acting on the legitimate behalf of the owner. Insofar as the client acts as a trustee or vicarious agent, he assumes joint and several liabilities with his trustor or client. If claims of third parties should exist, these have completely be declared when the order is placed. An omission or untrue information must be borne by the client.

The highest bid will be asumed within an offer period of 14 days. If a value is neither confirmed by the contractor nor proven beyond any doubt by the client or third party until the moment of sale, the price deviates only from the material value, as far as no higher price can be achieved locally. Alternatively, the contractor may assign his claims to a third party against the transfer of the artworks with all rights and obligations.

The liability for obviously deficient own statements of authorship at the time of negotiation is taken up to the amount of claimed fees. Any further liability of ArtExpert is expressly excluded. In addition, the owner of the artwork in question has to compensate the client of ArtExpert for obviously incorrect authenticition information at the time of the negotiation by providing refund or reduction of the purchase price. In case of obviously own fault by ArtExpert in a justified and unquestioning case, ArtExpert will advise and support the settlement between seller and buyer free of charge, without any legal claim. An incorrect statement of authenification is presumed if at least two recognized experts for the oeuvre accepted by ArtExpert can provide scientific proof by written appraisal that the offered artist does not descend the artwork in question. ArtExpert is not liable, however, if information about authorship was in line with the general state of knowledge at the time of purchase, no other facts had to be known on that deadline and dissenting lectures merely reflect the opinion of third parties.

However, a corresponding calculation is not required if a placement order is fulfilled or can be counted.

For all information and details of the seller or the buyer they are liable independently. The respective underwriter of ArtExpert assumes responsibility for its own.
7,10 Legal position in case of intermediary service: Based on his knowledge and experience, the expert as an art mediator does everything to make a deal between buyers and sellers possible. He can advise both sides in advance, but he guarantees generally strictly confidentiality. In order to maintain this absolute confidentiality in the further course, he can recommend a legal authority responsible under the relevant state law as a contact and paymaster for buyers and sellers. In this case, he needs confirmation accordingly seperately from both sides. The law firm in between is represented and confirming the position of the intermediary only to secure his position and to re-confirm it to both parties (buyer/seller). As an intermediary, ArtExpert or its designated expert will receive their commission or participation directly upon a successful outcome. Only in this event will all services provided in advance be rendered without additional charges. The intermediary will avoid unnecessary effort or demands on the firm appointed as trustee and paymaster. All questions should be directed to the intermediary before the legal representative of the buyer or seller contacts the appointed trustee firm. In any other case involving services or additional or unnecessary burden on the legal counsel or notaries engaged by the intermediary, the responsible party shall bear all resulting costs independently and hereby waives the right to object.
7.11 For each disruption of the process specified by the intermediary, e.g. through additional unauthorized intervention directly with the named law firm / Paymaster, the initiating party is self responsible to the law firm and is liable for a fee. Insofar as one party (buyer or seller) arbitrarily interrupts the known path prepared by ArtExpert or the respective responsible expert, this party shall be liable for arose or arising costs; this includes both, internal expenses at ArtExpert or the intermediary in accordance with the above terms and third-party costs incurred in this context.
7.12 If one party or both parties (buyer/seller) do not wish to have an independent responsible lawyer/paymaster under national law, you must guarantee and secure the role of mediator and the mediation costs agreed upon initiating a mediation in a legally binding manner in writing. Any settlement in this case must be legally binding in favor of the intermediary with regard to the law firm/paymaster appointed by the intermediary.

In case of direct or indirect references to external websites ("links"), which are beyond the scope of responsibility of ArtExpert, a liability  obligation would only come into force when ArtExpert has demonstrably knowledge of the contents and it would be technically possible and reasonable, to prevent the use in case of illegal content. ArtExpert therefore expressly declares that at the time of linking the respective linked pages were free of illegal content. ArtExpert has no influence on the current and future design and content of the linked pages. Therefore, ArtExpert dissociates from all contents of all links and linked sites, which were changed after the link was setting. For illegal, incorrect or incomplete contents and in particular for damages resulting from the use or disuse of such information, the provider of the refered page will be liable, not ArtExpert.
