SNDA Review for Commercial Leases
Financings put a stack of lender SNDAs on legal's desk at once. Abstria extracts the key terms of each SNDA with a link to the clause it came from, so counsel can check them against the lease without re-reading both documents end to end.

What is an SNDA?
An SNDA (subordination, non-disturbance, and attornment agreement) is an agreement between a tenant, its landlord, and the landlord's lender that sets out what happens to the lease if the lender forecloses. The tenant accepts that the mortgage comes first, and in exchange the lender agrees to leave the tenant in place.
Lenders ask for SNDAs because the leases are what make the property worth lending against: they want to know the rent continues after a foreclosure and that the lease cannot be used against them. Tenants sign them because without non-disturbance, a foreclosure on a mortgage that ranks ahead of the lease can, depending on state law, end the lease. Most commercial leases include a subordination clause that obliges the tenant to sign the lender's SNDA within a set number of days, usually on the condition that the lender gives non-disturbance in return.
Subordination clause vs SNDA
The subordination clause sits in the lease itself and says the lease will rank behind present and future mortgages. On its own it gives the tenant nothing back. The SNDA is the separate agreement, signed when a specific loan is made, in which that lender adds the non-disturbance promise. That is why tenants negotiate subordination clauses that only take effect once the lender delivers an SNDA, and why the clause and the SNDA should be read together.
The three parts of an SNDA
Subordination
The tenant agrees that its lease ranks behind the lender's mortgage or deed of trust. If the lender has to enforce its loan, its lien comes first.
Non-disturbance
The lender agrees that if it forecloses, it will not terminate the lease or remove the tenant, as long as the tenant is not in default. This is the protection the tenant is bargaining for.
Attornment
The tenant agrees to recognize whoever takes over the property after a foreclosure, whether the lender or a buyer at the sale, as its new landlord under the same lease.
What to check in a lender's SNDA
Lender forms are written to protect the lender, and the details that matter to the tenant sit in a handful of provisions. These are the terms worth extracting from every SNDA and keeping next to the lease abstract.
Conditions on non-disturbance
Non-disturbance usually applies only while the tenant is not in default "beyond applicable notice and cure periods". Check whether the cure periods match the lease or quietly shorten them.
Limits on the successor landlord's liability
Lender forms commonly say a successor landlord is not liable for the prior landlord's defaults, not subject to offsets or defenses the tenant had against the prior landlord, and not bound by rent prepaid more than a month ahead or by security deposits it never received.
Lender consent to lease amendments
Many SNDAs say the lender is not bound by amendments, terminations, or surrenders made without its consent. That makes every later amendment a lender-consent question, which matters when you keep the abstract current.
Notice and cure rights for the lender
The tenant often has to notify the lender of landlord defaults and give it time to cure before terminating or offsetting rent. These notice addresses and periods belong in the abstract next to the lease notice provisions.
Options, allowances, and other landlord promises
Check how the SNDA treats purchase options, rights of first refusal or offer, and unfunded tenant improvement allowances. Lender forms often carve these out of what a successor landlord must honor.
Rent payment direction
Most SNDAs let the lender direct the tenant to pay rent to the lender after a default notice, and protect the tenant for payments made as directed.
SNDA vs estoppel certificate
The two documents often arrive in the same financing package and are easy to confuse. An SNDA governs the future relationship between the lease and the loan; an estoppel certificate confirms what the lease says today.
| SNDA | Estoppel certificate | |
|---|---|---|
| Who signs | Tenant, lender, and usually the landlord | Tenant (sometimes the landlord) |
| What it does | Sets priority between the lease and the mortgage and what happens on foreclosure | Confirms the current facts of the lease on a given date |
| Who relies on it | Lender and tenant | Buyer or lender |
| When it comes up | New loans, refinancing, and sometimes at lease signing | Sales, refinancing, and lease assignments |
How Abstria handles SNDAs
The SNDA is reviewed in the context of the lease it affects, not as a standalone form. Scanned or poor-quality copies can still need closer manual review.
Upload the SNDA together with the lease and every amendment it relates to.
AI extracts the SNDA terms in 2-5 minutes, each linked to the clause it came from.
Review the extracted terms in the dual-panel editor next to the source document.
Counsel checks the extracted terms against the lease and decides what to push back on.

SNDA questions
What is a subordination clause in a commercial lease?
A subordination clause is a lease provision in which the tenant agrees that its lease will rank behind present and future mortgages on the property. Tenants usually negotiate for the clause to apply only if the lender signs a non-disturbance agreement, which is what an SNDA documents.
What does SNDA stand for?
SNDA stands for subordination, non-disturbance, and attornment agreement. It is a commercial real estate agreement between a tenant, its landlord, and the landlord's lender that sets out what happens to the lease if the lender forecloses.
What happens to a lease without an SNDA?
It depends on whether the lease or the mortgage has priority and on state law. If the lease is junior to the mortgage and the tenant has no non-disturbance agreement, a foreclosure can end the lease. That risk is why tenants ask for non-disturbance and why lenders ask for subordination.
Is an SNDA legally required?
No law requires one, but lenders usually require SNDAs from significant tenants as a condition of the loan, and many commercial leases oblige the tenant to sign one in a reasonable form within a set number of days after the landlord asks.
What is the difference between an SNDA and an estoppel certificate?
An SNDA sets the relationship between the lease and the mortgage going forward. An estoppel certificate confirms the current facts of the lease on a given date. Lenders often request both from the same tenants during a financing.
Can Abstria abstract SNDAs?
Yes. SNDAs are one of the document types Abstria supports alongside leases, amendments, estoppels, and other acknowledgements. Each extracted term links back to the clause in the SNDA so a reviewer can verify it.
Does AI replace attorney review of an SNDA?
No. Abstria extracts and organizes the terms so counsel can review faster. Deciding whether the lender's form is acceptable, and what to negotiate, remains a legal judgment.
