Estoppel Certificates and SNDAs: Why Your Lender Wants Them Signed

An estoppel certificate commercial lease may look like routine financing paperwork, but signing it can have significant consequences for a landlord or tenant. When a commercial property owner refinances a building or a buyer obtains a loan to acquire one, the lender wants reliable information about the leases that generate rental income. An estoppel certificate helps confirm the current terms of a lease, while a subordination, non-disturbance, and attornment agreement (SNDA) addresses what happens to that lease if the lender enforces its mortgage.

These documents matter because a commercial property’s value often depends on its tenants, rental income, and lease obligations. A lender needs to understand whether rent is current, whether the lease has been amended, whether either party claims a default, and whether the tenant has rights that could affect the lender’s collateral. Before signing either document, landlords and tenants should understand what they are confirming and what rights they may be agreeing to. A Commercial Real Estate Attorney can review the documents alongside the lease and identify provisions that need clarification or negotiation.

What Is an Estoppel Certificate in a Commercial Lease?

An estoppel certificate is a written statement in which a landlord or tenant confirms specified facts about an existing lease. A lender, prospective buyer, or other authorized party may request it to verify that the lease information used in evaluating the property is accurate. The certificate commonly identifies the lease, its commencement and expiration dates, the current rent, security deposits, amendments, renewal options, and whether either party claims an existing default.

For example, a lender underwriting a loan secured by a shopping center may want tenants to confirm their rent obligations and whether they have prepaid rent or received concessions. If a tenant has an undisclosed right to terminate the lease, or the landlord has agreed to a rent reduction that does not appear in the lender’s records, the lender’s financial analysis could be affected.

The precise statements depend on the certificate’s wording. Signing may confirm facts that a lender or buyer later relies upon when making a financial decision. In Yee v. Weiss, the Nevada Supreme Court considered an estoppel certificate under a commercial lease and held that the tenant could be bound by the signed certificate despite testifying that he had not read it, where there was no misrepresentation. The case is a practical warning: do not sign a certificate without checking each statement against the lease and the parties’ actual records.

What Is an SNDA, and Why Does the Lender Require It?

An SNDA is an agreement addressing the relationship between a commercial tenant, landlord, and the landlord’s mortgage lender. The three parts—subordination, non-disturbance, and attornment—deal with different issues that can arise if the property is financed, the landlord defaults on the loan, or the lender forecloses. The agreement’s actual terms determine the rights and protections each party receives.

Subordination concerns priority. A tenant may agree that its leasehold interest is subordinate to the lender’s mortgage. This can help the lender establish priority over the lease in a foreclosure scenario, depending on the existing interests and the agreement.

Non-disturbance is the tenant protection. The lender agrees, subject to the SNDA’s conditions, not to disturb the tenant’s possession if the property is foreclosed upon. Tenants should read this language carefully because the protection may depend on the tenant not being in default and complying with the agreement.

Attornment addresses the change in landlord. If the lender or a foreclosure purchaser takes ownership, the tenant agrees to recognize the new owner as landlord and continue the tenancy under the agreed terms. This provides continuity for the new owner while clarifying the tenant’s obligations.

The lender wants the SNDA because it helps define what happens to rental income and occupancy if the loan goes into default. The tenant may want the agreement because it can protect the right to remain in the premises after foreclosure. However, a tenant should not assume that every lender-provided SNDA offers the same protection; details such as notice, cure rights, and the treatment of lease amendments can make a substantial difference.

What Should You Check Before Signing an Estoppel Certificate?

Read the certificate alongside the signed lease, every amendment, and any written side agreement. Confirm the rent amount, additional rent, security deposit, lease dates, renewal or expansion options, prepaid amounts, concessions, and any outstanding landlord or tenant obligations. If the form states that the lease is unmodified, make sure that is accurate before certifying it.

Pay particular attention to statements about defaults and disputes. A certificate may ask whether the landlord has failed to make repairs, whether rent has been withheld or disputed, or whether either party has given a notice of default. If an issue exists, do not simply sign a form stating that there are no defaults. Describe the issue accurately, attach an explanation if appropriate, or ask for the statement to be revised before signing.

Tenants should also review provisions that could affect future rights. A certificate may ask whether any rent has been paid in advance, whether the tenant has options to renew, or whether the landlord has made commitments not included in the written lease. A missing option or undisclosed concession can become a source of conflict later. The goal is to confirm the actual lease position, not to provide the lender with a cleaner picture than the documents support.

Landlords should verify tenant statements against their rent ledgers, lease files, notices, and amendments before countersigning or forwarding certificates. If a tenant’s response conflicts with the landlord’s records, resolve the discrepancy or document it rather than treating the certificate as an administrative formality.

What Should Tenants Negotiate in an SNDA?

Tenants should focus on the protections that will matter if the landlord defaults on the loan. First, review the non-disturbance clause and determine whether the lender agrees to recognize the lease after foreclosure so long as the tenant is not in default beyond any applicable cure period. The language should clearly identify the conditions under which the tenant may remain in possession.

Second, review whether the lender must give the tenant notice of a landlord default and a reasonable opportunity to cure it. A landlord may fail to pay the mortgage even while the tenant pays rent on time. Without suitable notice and cure provisions, a tenant may have limited time to respond when the lender begins enforcement proceedings.

Third, check whether the SNDA restricts the tenant’s ability to enforce lease rights against a successor owner. Some lender forms limit the new owner’s responsibility for a landlord’s acts or omissions before foreclosure, prepaid rent, security deposits not actually received by the lender, or lease amendments made without lender consent. These provisions can materially affect the tenant’s position. They should be assessed against the lease and the transaction rather than accepted automatically.

Tenants should also consider whether the lender’s rights to approve amendments, rent reductions, extensions, or termination agreements could affect future negotiations with the landlord. The appropriate language depends on the lease, the lender’s requirements, and the tenant’s commercial needs.

What Happens If You Refuse to Sign?

The answer depends on the lease and the circumstances of the financing. Some commercial leases expressly require the tenant to provide an estoppel certificate within a stated period after receiving a request. Others include an obligation to sign an SNDA in a form meeting specified conditions. If the tenant refuses to comply with an enforceable lease provision, the landlord may argue that the refusal is a contractual breach.

However, receiving a lender’s form does not automatically mean every requested term is required by the lease or that the tenant must accept every proposed amendment. Review the original obligation, the deadline, the permitted form of the document, and any conditions on the tenant’s duty to sign. If a form includes statements that are inaccurate or terms that go beyond the existing agreement, raise those issues promptly and in writing.

Landlords should avoid promising a lender that a tenant will sign a document before checking the lease’s requirements. Lenders and buyers may need accurate information to close, but the parties should address discrepancies through a documented process rather than pressure a tenant to certify facts that are not true.

How Landlords and Tenants Can Avoid Delays

The easiest way to avoid financing delays is to maintain accurate lease records before a lender asks for them. Landlords should keep signed leases, amendments, renewal notices, rent concessions, security deposit records, and default notices organized and consistent with their accounting records. When an estoppel request arrives, the landlord can compare the tenant’s statements against the file and identify discrepancies before the closing date approaches.

Tenants should retain their own complete copy of the lease and all amendments, track rent payments and outstanding maintenance issues, and calendar any response deadline stated in the lease. If a certificate is inaccurate, identify the specific statement and propose a correction rather than rejecting the entire document without explanation. If an SNDA is requested, compare it with the existing lease and identify provisions that affect possession, notice, cure rights, and future dealings with the property owner.

Both sides should allow enough time for review. A certificate or SNDA may be short, but its consequences can extend beyond the immediate loan transaction. A careful review can help the parties complete financing without inadvertently changing the commercial relationship they originally negotiated.

Conclusion

An estoppel certificate confirms important facts about a commercial lease, while an SNDA sets out the parties’ rights if the landlord’s lender enforces its mortgage or takes ownership through foreclosure. Both documents can affect a tenant’s ability to remain in the property and a lender’s assessment of the income supporting its loan. Their wording matters, and neither should be treated as routine paperwork.

Before signing, verify every factual statement in the estoppel certificate and examine the SNDA’s subordination, non-disturbance, attornment, notice, and cure provisions. If the documents conflict with the lease or contain unfamiliar restrictions, seek clarification before returning them. Early review helps protect the parties’ contractual positions while keeping a commercial sale or financing on track.
