In California, within the Business and Professions Code, Section 1995.260, the landlord cannot unreasonably withhold the consent of the tenant to assign or sublease the property.
The landlord must agree to the lease transfer and usually records their consent to it via a document called a “license to assign.” The landlord is generally required to give what's called “reasonable consent” when deciding whether to allow a tenant to assign a lease or find a new tenant to sublease the property.
Unlike a Novation where consent of both the lessor and lessee is required for the third party to assume all obligations and liabilities of the original lessee, an assignment does not always need the consent of all parties.
The assignor must agree to assign their rights and duties under the contract to the assignee. The assignee must agree to accept, or "assume," those contractual rights and duties. The other party to the initial contract must consent to the transfer of rights and obligations to the assignee.
The transfer of a right from one party to another. For example, a party to a contract (the assignor) may, as a general rule and subject to the express terms of a contract, assign its rights under the contract to a third party (the assignee) without the consent of the party against whom those rights are held.
The "No Assignment" clause prohibits either party in a contract from transferring their rights or obligations under the agreement to a third party without prior written consent from the other party.
The legal framework governing consent of assignment varies by jurisdiction but generally requires that all parties to the original contract agree to the transfer. This consent ensures that the assignee can legally assume the rights and responsibilities outlined in the contract.
A form of landlord's consent favoring the tenant. This form of consent is used when a tenant requests the landlord's consent for an assignment of its lease and the landlord agrees to grant its consent.
In legal jargon, the old tenant who wants to get out of the lease is called the Assignor and the new person who wants to get the remainder of the lease is called an Assignee. The landlord remains the same.
Often an assignment clause is necessary to protect a tenant if there is no option for sublease, if the tenant does not plan to return to the space or to help with rental costs to help tenant avoid being penalized for ending their lease prior to the end of agreement.
