What Is a contract Assignment Clause?
A contract assignment clause governs the transfer of a tenant's full interest in a contract to a new party (the assignee). When a contract is assigned, the assignee steps into the tenant's position for the remainder of the contract term. Unlike subleasing — where the original tenant remains as a layer between the landlord and subtenant — assignment transfers the primary tenant relationship directly to the new party. Assignment is commonly used when a business sells, when a corporation restructures, or when a tenant needs to permanently vacate a space.
Assignment vs. Subleasing
The key difference between assignment and subleasing is scope and duration. Assignment transfers your entire contract interest — all rights and obligations — for the full remaining term. Subleasing creates a separate tenancy between you and a subtenant for some or all of your space for a portion of the remaining term. You remain the primary tenant in a subcontract; in an assignment, you exit the primary tenant relationship (though you may retain liability unless recontractd). Assignment is the preferred structure when you want to completely exit a contract as part of a business transaction.
Can You Transfer Just Part of the contract?
A partial assignment — transferring some but not all of your contracthold interest — is sometimes possible but more complex. It typically requires landlord consent and results in a split tenancy arrangement. More commonly, tenants who want to transfer only part of their space use a partial subcontract for the portions they don't occupy rather than attempting a partial assignment.

Assignment clauses typically require landlord consent, and the consent standard matters enormously. 'Not unreasonably withheld' consent means the landlord must have a substantive business reason to refuse — such as the proposed assignee's poor financial qualifications or intended use that violates building rules. 'Sole discretion' consent means the landlord can refuse for any reason or no reason. Push hard to negotiate the 'not unreasonably withheld, conditioned, or delayed' (NWCD) standard, and define specific grounds on which refusal is reasonable versus unreasonable.
Ongoing Liability After Assignment
Even after assignment, you may remain liable to the landlord if the assignee defaults — this is called 'continuing liability.' Many landlords refuse to recontract original tenants from liability even after assignment because the original tenant's creditworthiness was part of what they underwrote at contract signing. The most tenant-favorable outcome is a landlord recontract of liability upon assignment to a qualified assignee. At minimum, negotiate for recontract if the assignee has equal or greater financial qualifications. Without a recontract, you have a contingent liability that may appear on your financial statements for the full remaining contract term.
Assignment in Business Sales
Assignment clauses become critically important when selling a business. Most business asset sales include the contract as a core asset — and a restricted assignment clause can prevent or delay the sale. Some contracts allow assignment to a successor entity in the same business without additional consent; others require consent for any change in controlling ownership of the tenant entity, even without a formal assignment. If you're a business owner, read your assignment clause carefully and consider its impact on your future exit options before signing.
Change of Control Provisions
Many commercial contracts include 'change of control' provisions that treat a sale of the business entity (even without a formal assignment) as a deemed assignment requiring landlord consent. This means selling your LLC or corporation triggers consent requirements even though the contract technically has not been assigned. Negotiate to exclude asset sales, mergers, and internal restructurings from the change of control definition, and to make permitted transfers to affiliates and subsidiaries consent-free.
Red Flags and Negotiation Tips
Red flags include absolute prohibitions on assignment, landlord recapture rights upon assignment requests (where the landlord can simply take back the space instead of approving your assignment), change of control provisions that broadly define what triggers consent, and profit participation requiring you to share any above-market value with the landlord. Negotiate for: consent not to be unreasonably withheld, conditioned, or delayed; a defined response timeline (typically 15–30 business days); the right to assign to affiliates and subsidiaries without consent; automatic approval upon business sale to a financially qualified buyer; and recontract of liability upon assignment.
