A Standard Document establishing the rights and priorities between a lender's mortgage lien and a tenant's leasehold interests in mortgaged commercial property. This Standard Document discusses SNDAs from a tenant's perspective, including matters such as lien subordination, attornment, landlord defaults, preserving a tenant's specifically negotiated rights and defenses, and the effect of state and local law on the enforceability and construction of subordination, non-disturbance, and attornment agreements. The first drafting note of this Standard Document contains a link to a comparison redline that shows the changes between Practical Law's pro-lender SNDA and this pro-tenant version.
