What Is an Attornment Clause?
An attornment clause in a commercial lease is a provision requiring the tenant to recognize and accept a new property owner as their landlord if ownership transfers — whether through foreclosure, deed-in-lieu, sale, or any other conveyance. The word "attorn" comes from the Old French atorner, meaning "to turn over" or "assign." By executing an attornment clause, a tenant agrees to "turn over" their allegiance from the original landlord to whoever acquires the property.
In practical terms, if your landlord defaults on their mortgage and the lender forecloses, an attornment clause requires you to continue paying rent and performing all lease obligations — now directed to the foreclosing lender or the subsequent purchaser at foreclosure sale. You've essentially agreed in advance that the lease continues with the new owner on the same terms as before.
Attornment is almost always paired with subordination (the tenant's agreement that their lease ranks below the mortgage) and non-disturbance (the lender's promise that it won't terminate the tenant's lease upon foreclosure, provided the tenant isn't in default). Together, these three elements form the classic SNDA agreement — Subordination, Non-Disturbance, and Attornment.
When a lender forecloses on a commercial property, they need assurance that the existing tenants will continue performing under their leases. Without attornment, a foreclosing lender faces a potential argument from tenants that the original lease was extinguished when the original landlord was ousted — meaning tenants could claim they owe nothing and the lender is stuck with vacant space. Attornment eliminates this uncertainty and protects the income stream the lender depends on to recover their loan.
The Three Components of SNDA: How Attornment Fits In
Understanding the attornment clause requires understanding its place within the broader SNDA framework. The three components work together, and they don't make sense in isolation:
S — Subordination: The Tenant's Concession
Subordination is the tenant's agreement that their lease interest is junior to (below) the lender's mortgage lien. Most commercial leases contain automatic subordination clauses — meaning the tenant's lease is subordinate to any existing or future mortgage the landlord places on the property without the tenant needing to take any further action.
The implication: if the lender forecloses, the lender's rights take priority over the tenant's lease. Without more, this means the tenant's lease could be terminated in the foreclosure proceeding.
N — Non-Disturbance: The Lender's Concession
Non-disturbance is the lender's agreement that even if they foreclose and acquire the property, they will not disturb the tenant's occupancy — provided the tenant is not in default under the lease. This is the most tenant-protective component of the SNDA and the one tenants most need to obtain.
Without non-disturbance, a tenant who agrees to subordinate has given up enormous ground in exchange for nothing. The lender has the legal right to terminate a subordinate lease in foreclosure, and nothing stops them from doing so.
A — Attornment: The Continuity Mechanism
Attornment is the tenant's promise to recognize the new owner (whether the foreclosing lender, a court-appointed receiver, or a third-party buyer at foreclosure sale) as their new landlord under the existing lease terms. Attornment ties the subordination and non-disturbance together — the tenant acknowledges the new ownership structure, and the lease continues in full force.
Practically, this means the tenant continues paying rent (now to the new owner), maintains their space, exercises options, and performs all other obligations under the lease as if the landlord change never happened.
The Foreclosure Scenario: Step by Step
To see how the attornment clause works in practice, walk through a typical foreclosure scenario:
- Year 1 — Lease signed, SNDA executed. Tenant signs a 10-year office lease. Landlord's existing lender requires the tenant to execute an SNDA. Tenant negotiates non-disturbance in exchange for subordination and attornment commitments.
- Year 4 — Landlord defaults on mortgage. Rising interest rates and declining occupancy in the building cause the landlord to miss debt service payments. The lender initiates foreclosure proceedings.
- Year 5 — Foreclosure completed. The lender acquires the property at the foreclosure sale. Without an SNDA, the tenant's subordinate lease could be terminated. With the SNDA, the non-disturbance provision prevents the lender from terminating the lease.
- Attornment kicks in. The tenant is notified of the ownership change and instructed to pay rent to the lender (or their property manager). The tenant attorms to the lender as the new landlord, and the lease continues on identical terms.
- Year 6 — Property sold to new investor. The lender sells the property. The tenant again attorms to the new buyer. The lease continues undisturbed.
This is the ideal outcome with proper SNDA protections. The tenant's business is never disrupted despite complete ownership change at the property level.
Many standard landlord-form leases contain automatic subordination clauses but no corresponding non-disturbance provisions from the lender. If you've agreed to subordinate your lease without a non-disturbance agreement in hand, you've given the lender the legal right to terminate your tenancy in a foreclosure — and received nothing in return. This isn't theoretical: commercial real estate foreclosures happen regularly, and tenants without SNDA protections have been displaced from spaces they'd occupied for years, losing build-outs, customer bases, and operational continuity.
SNDA vs. Estoppel Certificate vs. Lease Recognition Agreement
| Document | Parties Involved | Primary Purpose | Who Benefits |
|---|---|---|---|
| SNDA Agreement | Tenant, Landlord, Lender | Sets priority rules and foreclosure survival rights | Lender (subordination, attornment) + Tenant (non-disturbance) |
| Estoppel Certificate | Tenant (certifying to Lender/Buyer) | Confirms lease status, no defaults, key terms | Lender/buyer in due diligence |
| Lease Recognition Agreement | Tenant, New Owner | Post-foreclosure confirmation of lease continuation | New owner and tenant post-transition |
| Non-Disturbance Agreement (NDA standalone) | Tenant, Lender | Lender's promise not to terminate lease upon foreclosure | Tenant |
Key Negotiation Points in Attornment and SNDA Language
Not all SNDA agreements are created equal. The specific language determines exactly how much protection a tenant receives. Here are the critical provisions to negotiate:
1. Scope of Non-Disturbance
The non-disturbance provision should expressly state that the lender will not terminate the lease, disturb the tenant's possession, or name the tenant as an adverse party in any foreclosure action — provided the tenant is not in default beyond any applicable cure period. Watch for carve-outs that allow the lender to terminate the lease even if the tenant is current — these eliminate the protective value of the provision.
2. Lender's Obligations as Successor Landlord
What obligations does the lender assume if they become landlord? Standard SNDA language often limits the lender's obligations significantly. Common lender carve-outs include refusing to:
- Be bound by any rent paid more than one month in advance
- Be bound by any lease modification made without lender consent
- Be bound by the original landlord's prior defaults (including construction obligations, TI commitments, or repair obligations)
- Credit any security deposit not actually received by the lender
- Complete any tenant improvements the original landlord agreed to build
Negotiate to limit these carve-outs as much as possible, particularly on TI obligations and security deposit credits. A lender who forecloses and inherits your lease should be bound by the lease's material terms — including obligations the prior landlord undertook.
3. Future Financing
Many SNDA agreements require the tenant to subordinate to future financing — not just the current mortgage. If the lease automatically subordinates to any future mortgage the landlord places on the property, the tenant needs confirmation that each future lender will execute an equivalent non-disturbance agreement. Without this, the tenant could end up with automatic subordination to a new mortgage but no non-disturbance protection from that new lender.
4. Refinancing Protections
When a landlord refinances, the existing lender releases their mortgage and a new lender takes over. If your SNDA was with the old lender, it doesn't bind the new one. Require your lease to include a condition that any refinancing triggers a new SNDA obligation from the incoming lender — or require landlord to deliver an executed SNDA from any replacement lender within a specified timeframe.
5. Receiver Obligations
Prior to completing a foreclosure, a lender may have a court-appointed receiver take over management of the property. SNDA agreements should address receiver scenarios as well — the tenant should attorn to a receiver and the receiver should be bound by the non-disturbance obligation until a final disposition of the property.
Some leases include "deemed subordination" clauses stating that the tenant automatically agrees to subordinate to any mortgage recorded against the property — current or future — without any further action. This type of provision is maximally landlord/lender favorable and maximally dangerous for tenants. If your lease contains a deemed subordination clause, ensure it's conditioned on the lender delivering a non-disturbance agreement. The right way to draft this: "This Lease shall be subject and subordinate to any mortgage... provided that the holder of such mortgage shall execute and deliver to Tenant a non-disturbance agreement in form reasonably acceptable to Tenant."
Foreclosure-Specific Risks: What Attornment Doesn't Protect
Even with a properly signed SNDA, there are scenarios where a tenant can suffer harm in a landlord foreclosure:
Lease Modifications After SNDA Execution
If the landlord and tenant modify the lease after the SNDA was executed, the lender typically won't be bound by the modification (especially if it materially increases the lender's obligations or reduces lease income). Tenants who negotiate lease amendments — rent abatement, TI additions, term extensions — should require a new SNDA or at minimum a lender consent to the modification. Without this, the modification may be unenforceable against the new landlord post-foreclosure.
Prepaid Rent
Most SNDA agreements protect the lender (as successor landlord) from being bound by rent paid more than one month in advance. If you've prepaid several months of rent — perhaps as part of a negotiated concession — you may not be able to offset that prepaid amount against future obligations to the new landlord. The lender would argue they never received the prepayment and cannot be held responsible for it.
Security Deposit Recovery
If your security deposit was held by the original landlord and never transferred to the lender, the lender may refuse to credit the deposit. Negotiate a provision requiring the original landlord to transfer all security deposits to the lender upon loan origination, or require the lender to acknowledge the deposit amount in the SNDA itself.
Construction Obligations
This is the most financially significant risk. If the landlord agreed to construct tenant improvements or deliver a space in a specific condition, the lender in an SNDA will often disclaim any obligation to complete unfinished work. A tenant whose TI build-out was half-complete when the landlord defaulted could be left with an unusable space and no right to force the new landlord to complete construction. Negotiate hard to have the lender assume outstanding construction and TI delivery obligations.
One of the most serious foreclosure risks for tenants is the loss of unpaid TI allowances. If a landlord defaults before paying an agreed TI allowance (which is common early in a lease when the landlord has maximum financial exposure), the foreclosing lender may disclaim the obligation. This is particularly devastating for tenants who signed long leases in exchange for large TI allowances — they've committed to the rent obligation for 10 years but may never collect the $500K+ they were promised. Always secure TI allowances with a completion bond, letter of credit, or escrow rather than relying solely on the landlord's promise.
Subordination Without Non-Disturbance: The Unprotected Tenant
The danger of subordination-only provisions is worth examining in detail. Many landlord-form leases contain a clause along these lines:
"This Lease is and shall be subject and subordinate to all ground or underlying leases and to all mortgages, deeds of trust, and other hypothecations which now affect the Premises and to any and all renewals, modifications, consolidations, replacements, and extensions thereof."
This clause makes the tenant's lease subordinate to existing and future mortgages — full stop. There is no provision conditioning this subordination on the lender providing non-disturbance. The tenant has agreed to be in the junior position with no corresponding protection.
In some states, courts have implied a non-disturbance obligation based on equitable principles, but this is uncertain and varies by jurisdiction. The only reliable protection is a written, signed non-disturbance agreement from the actual lender.
| SNDA Structure | Tenant Protection Level | What Happens in Foreclosure |
|---|---|---|
| Full SNDA (S + NDA + A signed by lender) | ✅ Strong | Lease survives; tenant attorms to new owner; business continuity preserved |
| Subordination + Attornment only (no NDA) | ⚠️ Minimal | Lender may terminate lease; tenant may be evicted; no contractual recourse |
| No subordination, no SNDA (senior lease) | ✅ Strong (by priority) | Lease survived because it's senior to the mortgage — but rare in practice |
| Deemed subordination clause without NDA condition | 🚨 Dangerous | Automatic subordination to future mortgages; no automatic NDA protection |
When to Negotiate Your SNDA: Timing and Leverage
Timing is critical. Tenants have the most leverage to negotiate favorable SNDA terms at the following points:
At Lease Execution (Best Time)
Before signing the lease, make delivery of an executed SNDA from the existing lender a condition precedent to the lease becoming effective. If the landlord cannot obtain the lender's signature, the tenant is not obligated to sign the lease. This is maximum leverage — the landlord wants to execute the lease and will work hard to get lender cooperation.
Before Occupancy
If the SNDA wasn't conditioned at lease signing, require it before taking occupancy. At this point the landlord has signed a lease and wants the tenant to move in — they're motivated. Once you're in the space and operational, the pressure is off the landlord and on you.
During Refinancing
When a landlord refinances, require a new SNDA from the incoming lender as a condition of any consent or cooperation the tenant provides (such as signing an estoppel certificate in connection with the new loan). Lenders almost always require tenant estoppels — use that leverage to get your NDA in return.
The most protected tenants make SNDA execution a condition precedent to any obligation arising under the lease. Include this language in your lease: "Tenant's obligations hereunder are expressly conditioned upon Landlord delivering to Tenant a fully executed Subordination, Non-Disturbance, and Attornment Agreement from Landlord's current lender in a form reasonably acceptable to Tenant within [30] days of the Effective Date of this Lease." This turns SNDA delivery into a landlord obligation, not an afterthought.
Checklist: SNDA and Attornment Clause Review
- Non-disturbance is in writing and signed by the lender — not just referenced in the lease or promised by the landlord verbally.
- SNDA is three-party — signed by tenant, landlord, AND the actual lender. A two-party SNDA between tenant and landlord is unenforceable against the lender.
- Non-disturbance applies to all successors — including receivers, trustees in bankruptcy, and subsequent purchasers at foreclosure sale.
- Lender's carve-outs are minimized — especially on TI obligations, security deposits, and lease modifications made before foreclosure.
- Future financing trigger — lease requires landlord to deliver new SNDA from any replacement lender within 30–60 days of refinancing.
- TI and construction obligations are secured — not just contractual promises from the landlord that a new owner won't be bound by.
- SNDA delivery is a condition precedent — tenant's obligations under the lease don't commence until SNDA is fully executed.
- Prepaid rent and security deposit are addressed — SNDA specifies that lender acknowledges any security deposit and won't disclaim credit for rent paid in advance.
- Lease modifications require lender consent — any material amendment to the lease should be consented to by the lender to ensure it's binding post-foreclosure.
- Subordination is not "automatic" or "deemed" without a corresponding NDA condition — or if automatic subordination is used, it's conditioned on lender providing NDA.
Common Red Flags in Attornment Clauses
The lease requires subordination to all existing and future mortgages but contains no requirement for the lender to provide a non-disturbance agreement. Tenant has agreed to junior status with no protection in foreclosure.
SNDA states lender will not be bound by any representation, warranty, or obligation of the original landlord — including TI allowances committed but unpaid, construction obligations, or security deposit obligations. Tenant loses all prior landlord promises in foreclosure.
SNDA only covers the specific existing loan — not future refinancing. When the landlord refinances, the tenant is left with automatic subordination to the new mortgage and no non-disturbance agreement from the new lender.
SNDA addresses foreclosure but not court-appointed receivers who often take control of properties during protracted foreclosure proceedings. Tenant may face receivership management for months without clear contractual protections.
The lease requires the landlord to "use commercially reasonable efforts" to obtain an SNDA from the lender — but doesn't make SNDA delivery a condition of the lease becoming effective. If the lender refuses, the tenant is still bound by the lease, subordinated, and unprotected.
Frequently Asked Questions
An attornment clause is a lease provision requiring a tenant to recognize and accept a new owner as their landlord if the property changes hands — through foreclosure, sale, or other transfer. By signing an attornment clause, the tenant agrees to continue performing all lease obligations with the new owner on the same terms as the original lease.
Subordination means the tenant's lease ranks below the lender's mortgage. Non-disturbance means the lender promises not to terminate the tenant's lease if they foreclose, provided the tenant is not in default. Attornment means the tenant agrees to recognize whoever acquires the property as the new landlord. Together, these three elements form the SNDA agreement.
Yes — subordination without non-disturbance is extremely dangerous. A subordination clause alone means the tenant's lease could be wiped out in a foreclosure. Without a non-disturbance agreement from the lender, the foreclosing lender has no obligation to honor the lease and can evict the tenant even if they've done nothing wrong. Always pair subordination with a signed non-disturbance agreement from the lender.
An SNDA (Subordination, Non-Disturbance, and Attornment) agreement is a three-party contract among the tenant, landlord, and lender. The attornment clause is one component — it's the tenant's promise to recognize the new landlord after foreclosure. The SNDA ties this obligation to the lender's reciprocal promise (non-disturbance) not to disturb the tenant's occupancy.
When a landlord is foreclosed on, the outcome for tenants depends on their lease terms and any SNDA agreement. Without an SNDA, tenants with subordinate leases may have their tenancy terminated. With a properly signed SNDA including non-disturbance, the tenant's lease survives and the tenant simply attorms to the new owner — whether that's the lender or a third-party buyer at foreclosure.
Before occupying the premises — ideally as a condition precedent to the lease becoming effective. After move-in, the lender has much less incentive to cooperate and the tenant has already committed to the space. For new leases on encumbered properties, require the landlord to deliver a fully executed SNDA from the existing lender simultaneously with lease execution or as a condition precedent to tenant's obligation to occupy.
