Duty to sign a Subordination, Non-Disturbance, and Attornment agreement.
By Angel Campa, Founder · Updated March 2026
An SNDA protects the tenant if the landlord defaults on their mortgage. Without a non-disturbance agreement, the lender can terminate the lease upon foreclosure, evicting a rent-paying tenant. The subordination component also affects the tenant's priority in bankruptcy proceedings. For tenants with significant build-out investments or long-term leases, an SNDA is essential insurance against landlord financial distress.
Found in the "Subordination" or "SNDA" section, typically in the miscellaneous provisions near the end of the lease. The lease usually requires the tenant to execute an SNDA upon request, and the landlord should be required to obtain the lender's agreement.
Lextract uses a combination of AWS Textract OCR and Claude AI to identify and extract the snda requirement from your lease PDF. The AI searches for all pages of the document, then assigns a confidence score based on OCR quality and extraction certainty. Fields with lower confidence are flagged for human review.

SNDA stands for Subordination, Non-Disturbance, and Attornment. Subordination means the lease is junior to the mortgage. Non-disturbance means the lender will honor the lease even after foreclosure. Attornment means the tenant agrees to recognize the new owner. The non-disturbance provision is the most important part for tenants.
Yes, especially for long-term leases or leases with significant TI investment. Without an SNDA, the lender can terminate the lease upon foreclosure. The lease should require the landlord to obtain the lender's execution of an SNDA within a specified period (e.g., 60 days of lease execution).
