International lease: The international lease deals with the nature of the lease agreement in which one or more parties to the lease are established or resident in different countries. Under normal circumstances, property owners are free to do whatever they want with their property (for a legitimate purpose), including processing or handing over the property to a tenant for a limited period of time. If a landlord has granted the property to another landlord (i.e.dem tenant), any intervention in the unspoken consumption of the property by the tenant himself is illegal. 7 Leveraged leasing is used to finance assets that require a huge investment. The leveraged leasing contract consists of three parties, the underwriter, the lessor and the lender. The loan is usually secured by the asset mortgage in addition to the rent allocation. In the context of lever leasing, a wide range of equipment such as railways, coal mines, pipelines, ships, etc., are acquired. The concept of leasing is based on the use of guarantees as a method of guarantee. The right to security remains with the leasing company and is transferred to the underwriter only when the underwriter has the opportunity to acquire the guarantees after the conclusion of the payment plan under the lease at their residual value. Leasing is a credit or financial transaction and is also a guarantee without ownership of the assets, since the underwriter remains in possession of the assets. Deprivation of rights is the obtaining of title to the property and is most often negotiated with the landlord when a tenant pays only a basic rent. At the time of the merger, the landlord and tenant are identical and can terminate a tenancy agreement if there are no subtenants in certain jurisdictions.

From a commercial point of view, leasing seems to be solitary, although it has several legal relationships that are legally different. Leasing is a complex transaction with different legal relationships and is based on one or more contracts. The application of private international law to leasing operations allows and leads to its fragmentation. The rules for contracts (Article 10.5 of the BGB or the Rome Convention of 1980) arise from legal conditions that are not only the result of the contractual terms themselves. Each element of a leasing transaction must be subject to a separate lex contractus review. In the absence of an applicable law chosen by the parties, the legal framework of the Rome Convention is applied between the leasing company and the taker, which leads to the application of the law of the usual residence of the leasing company.
