A vehicle lease assumption clause requiring an outgoing lessee to maintain joint liability for a successor’s future debts has been ruled legally invalid by the Higher Regional Court of Frankfurt am Main (OLG Frankfurt am Main). According to the court’s August 19, 2026 ruling, published on Tuesday under docket number 17 U 141/25, such terms in standard business conditions are considered surprising and void under Section 305c Paragraph 1 of the German Civil Code (BGB).
The dispute arose after a consumer leased a Mercedes CLA and later arranged for her former roommate to take over the agreement. All three parties, including the lessor, signed a transfer contract. The standard terms drafted by the lessor contained a provision stating that the original lessee would remain jointly liable for all current and future obligations incurred by the new contract partner. When the successor defaulted on monthly lease payments, the lessor demanded nearly 20,000 euros from the original lessee. The Frankfurt am Main Regional Court initially ruled in favor of the lessor in a November 11, 2025 decision under file number 2-19 O 586/23.
Court Finds Joint Liability Clause Surprising
The 17th Civil Senate of the OLG Frankfurt am Main overturned the lower court judgment and upheld the appellant’s appeal. The court held that a person entering into a contract transfer with the explicit intent of exiting a lease agreement reasonably expects to be fully released from all contractual obligations. According to the judges, an outgoing party does not anticipate remaining on the hook for a successor’s debts, particularly because stepping away strips them of any further control over the vehicle or the ongoing contract management.
Furthermore, the structure of the document itself precluded the clause from becoming an integrated, expected part of the deal. The Senate noted that headings such as “transfer contract,” “previous lessee,” and “transferee” signaled a complete exit rather than a lingering financial entanglement. The liability text lacked visual separation or emphasis within the form text, failing to counteract what the court termed a trapping effect. The ruling is final and not subject to further appeal.
