While most commercial leases contain a requirement that the tenant will execute a “Subordination, Non-Disturbance and Attornment Agreement,” commonly referred to a an “SNDA,” a majority of tenants who have signed such leases, and most likely several of the real estate agents who have represented those tenants, would be hard pressed to explain the meaning of an SNDA, and why they are needed by both commercial lenders and tenants. 

As implied by its name, an SNDA is really three agreements all wrapped up in one neat package.  All three aspects of the SNDA only come into play in the event that the leased property is foreclosed by a lender holding a security interest (mortgage or deed of trust) secured by the leased property.  Let’s first look at the “subordination” part of the SNDA.  If the lease is in existence at the time that the lender records his security interest against the property, then the lease is superior to the security interest, and upon foreclosure by the lender, the title obtained by the purchaser at the foreclosure sale will be subordinate, or subject to, the existing lease.  When a tenant signs an SNDA, the tenant is agreeing to reverse the priorities and resultant outcome upon foreclosure; namely, that the lender’s security interest becomes superior to the preexisting lease, and upon foreclosure by the lender, the title obtained by the purchaser at the foreclosure sale will be superior to the existing lease.  Such change in priority is critical for the lender, as absent a non-disturbance agreement, based upon its superior interest the lender or other purchaser at the foreclosure sale would have the right to terminate the lease upon completion of the foreclosure.

The “non-disturbance” part of the agreement, which is also referred to as a “right of quiet enjoyment,” is exactly as indicated by its name.  By entering into an SNDA, the lender has agreed that upon acquiring title to the leased property through a foreclosure sale, that the lender, or any other purchaser at the sale, will “not disturb” the tenancy of the tenant, so long as the tenant is not in default, and that such tenancy will continue as if the foreclosure had never occurred.

The “attornment” part of the agreement, which perhaps is the most confusing part of an SNDA, simply means that the tenant is agreeing to acknowledge the purchaser at the foreclosure sale as the new landlord under the lease.   This is merely a way to formalize the legal relationship that exists between a landlord and the new owner of the property.

The SNDA is beneficial for both the lender and for the tenant.  A lender is able to avoid any consequences having a leasehold interest in a superior position to its lien or its title in the event of foreclosure, while a tenant is given the peace of mind of knowing that if its landlord loses the leased property through foreclosure that its tenancy will not be disturbed.
