GRP Rainer Attorneys and Tax Accountants in Cologne, Berlin, Bonn, Düsseldorf, Essen, Frankfurt, Hamburg, Hanover, Munich, Stuttgart, Bremen, Nuremberg and London www.grprainer.com/en explain: In its judgment from 23 January 2013 (Ref.: XII ZR 35/11), the German Federal Supreme Court (BGH) continued its judicature on the disclosure of representation upon conclusion of long-term tenancy leases. If a member of a civil law company (GbR) wants to represent the company at the conclusion of a long-term lease agreement, then the member with signature authority should include a company stamp when signing on behalf of the company. It is not necessary to comply with the formal requirement in writing that stipulates that upon conclusion of a long-term lease that all members of the civil company are signatories to the lease. Rather, it is sufficient if the representing member’s signature is accompanied by an addition (the company stamp) which indicates the representative status of the signatory and thus brings expression to the sole entitlement of the representing member to represent the company.
