Abstract: Land constitutes a fundamental human necessity with significant economic and social value, making it a common object of legal agreements, including lease contracts. In practice, leased land is sometimes used as collateral by the owner without the tenant’s knowledge, resulting in legal uncertainty and potential losses. This phenomenon occurred in Gedung Harapan Village, Penawar Aji District, Tulang Bawang Regency. This study aims to examine the practice of land leasing used as collateral and to analyze the legal protection afforded to tenants under the Indonesian Civil Code (KUHPerdata). The research employs field research with a descriptive qualitative and normative juridical approach. Data were collected through observation, interviews, and documentation, and analyzed qualitatively using an inductive method. The findings indicate that lease agreements are generally conducted informally without written contracts, leading to legal uncertainty and disadvantages for tenants. Normatively, legal protection is regulated under the Civil Code, Law Number 4 of 1996 concerning Mortgage Rights, and Law Number 8 of 1999 concerning Consumer Protection; however, its implementation remains suboptimal. Therefore, enhancing legal awareness and formalizing written agreements are essential to ensure legal certainty and justice. Keywords: Legal Protection, Land Lease, Mortgage Rights.
