An estoppel certificate is a short signed statement in which a tenant confirms the current facts of its lease to someone who is about to rely on them, usually a buyer purchasing the building or a lender financing it. It locks down the basics: who the parties are, how much rent is, when the lease started and ends, how big the security deposit is, whether any amendments exist, and whether either side is in default. The name comes from the legal doctrine of estoppel. Once you certify a fact and a buyer or lender acts on it, you are generally barred from later claiming something different. That is the whole point: the new owner or lender gets a reliable snapshot of the lease straight from the tenant, instead of taking the seller's word for it. It is most common in commercial real estate, where a lease is a major part of a building's value, but it shows up in residential deals too. A landlord can be asked to sign one as well, though the tenant version is far more common. The certificate confirms the lease; it does not create or change it, and it is not a seller's disclosure of property defects. Most requests come during due diligence, and the lease itself usually sets a short deadline to return it, commonly around 10 days.

Estoppel certificate, estoppel letter, estoppel agreement: one document
These names all point to the same thing: a signed statement confirming the facts of a lease. "Estoppel certificate" and "estoppel letter" are interchangeable. An "estoppel agreement" is usually the same document with signature lines for more than one party. Do not let the variety of names make you think you are dealing with something unfamiliar.
It helps to be clear about what the certificate is not. It is not a lease, and it cannot rewrite one. If the certificate and the lease ever disagree, the lease still governs the relationship between landlord and tenant; the certificate just fixes what the tenant told a third party who relied on it. It is also not a seller disclosure. A seller disclosure is the owner's statement about the condition of the property, roof, wiring, past leaks, and the like. An estoppel certificate says nothing about condition. It is strictly about the lease: rent, term, deposit, defaults. Keep those two apart, because buyers often collect both at the same time and they do different jobs.

What the certificate asks you to confirm
A tenant estoppel certificate is mostly a checklist of lease facts. Expect to confirm each of these, either by agreeing to the statement or by writing in the exception.
Rent and term: the current base rent, the date rent is paid through, the commencement and expiration dates, and any renewal options still open.
Prepaid rent and concessions: whether you have paid more than a month ahead, and whether any free rent or allowance is still owed to you rather than already used.
Security deposit: the amount the landlord holds and whether it is cash or a letter of credit.
Amendments: that the lease is unchanged, or a list of every amendment, side letter, and guaranty by date.
Defaults: that neither you nor the landlord is in default, or a plain description of any problem.
Claims and offsets: that you have no outstanding claim against the landlord and no right to deduct from rent, or a description of what you are claiming.
Other rights: any purchase option, right of first refusal, sublease, or assignment, so the buyer knows what it is taking subject to.

How to fill it in
Work through it with your signed lease open next to you. The certificate is only useful if every line matches the actual document.
Fill the header: the requesting party, the lease date, the landlord, your name as tenant, and the premises and property addresses.
Enter the dates and dollars: commencement, expiration, current rent, the date rent is paid through, and the deposit amount.
List amendments by date, or write "none." Do not leave a blank, because a blank reads as "none" and can bind you to an incomplete picture.
Answer the default and claims questions honestly. If the landlord owes you a repair or an allowance, say so here rather than signing a clean certificate you will regret.
Fill in or strike out the options, subleases, and purchase rights so the buyer knows exactly what survives the sale.
Sign and date. For a business tenant, add the signer's name and title so the buyer knows the person had authority.

Read it against your lease before you sign
This is the part that catches tenants out. An estoppel certificate is designed to be relied on, which means it can override your ability to argue a fact later even if the fact was actually in your favor. If the form says the landlord has completed all its work and you sign it, you may lose the ability to make the landlord finish a repair it still owes you. If it lists a termination date that quietly drops a renewal option you were counting on, you can be held to the shorter term.
So check every line against the lease. Where the pre-filled form is wrong or leaves something out, correct it. If the landlord promised 2 months of free rent and only 1 has been applied, write that in. If a repair is outstanding, name it. If there is a side letter the form ignores, add it. Most forms give you little room, so attach a short addendum if you need to and reference it on the face of the certificate. One more thing to watch: many commercial leases require you to return the certificate within a set window, often around 10 days but sometimes 15 or as few as 5 business days, and some say that if you miss it, the landlord's version is treated as correct or the landlord can sign for you as your attorney-in-fact. Do not sit on the request. If a lease requires it, refusing to sign an accurate certificate can itself be a default.

Why a buyer or lender wants it, and why you are bound
A building's leases are a big part of what it is worth. A buyer paying for a rent roll, or a lender lending against it, wants the numbers confirmed by the people actually paying rent, not just by the seller who has every reason to present the leases favorably. The estoppel certificate is that independent confirmation, straight from each tenant.
The reason it sticks is the doctrine the document is named for. Once you state a fact in writing and someone relies on it to their detriment, the law generally will not let you turn around and contradict it. California puts this in statute, and it is a clear illustration of the rule most states apply through common law. California Evidence Code section 622 provides that "the facts recited in a written instrument are conclusively presumed to be true as between the parties thereto, or their successors in interest," except for a recital of consideration. Section 623 adds the broader estoppel principle: a person who "by his own statement or conduct, intentionally and deliberately led another to believe a particular thing true and to act upon such belief" cannot later contradict it in litigation. That is exactly what a signed estoppel certificate does. You state the lease facts, the buyer or lender relies on them to close or to fund, and you are held to what you certified. Note that the reliance clause names successors and assigns, so a later owner or a lender that takes over the loan gets the same protection.

Estoppel certificate versus SNDA
These two often arrive together in a commercial deal, and they are easy to confuse. An estoppel certificate is about the present: it confirms the current facts of the lease. An SNDA, which stands for subordination, non-disturbance, and attornment, is about the future, specifically what happens if the lender forecloses. Subordination means the tenant agrees its lease ranks behind the lender's mortgage. Non-disturbance is the tenant's protection in return: as long as the tenant keeps paying and performing, a foreclosing lender will not evict it or cancel the lease. Attornment means the tenant agrees to treat the new owner after foreclosure as its landlord.
Short version: the estoppel certificate says "here is where the lease stands today," and the SNDA says "here is what happens to the lease if the loan goes bad." A lender financing a leased property commonly asks a significant tenant for both. If you are handed an SNDA alongside this certificate, read it separately; the non-disturbance language is the piece worth getting right as a tenant.

Signing, deadlines, and e-signatures
An estoppel certificate does not need to be notarized or witnessed. A tenant's signature is enough, and for a business tenant the person signing should have authority to bind the company. You can sign it electronically: an e-signature on an estoppel certificate is valid under the federal ESIGN Act and state UETA laws, the same rules that back any e-signed business document, so an electronic signature carries the same weight as ink.
The real pressure is timing, not formality. Because these are collected during due diligence against a closing date, the request usually comes with a deadline, and the lease may already set one. Fill it in promptly and accurately. The goal is a certificate that is true on the day you sign it, because that is the day the buyer or lender will rely on it. This template is a general starting point, not legal advice; a commercial lease can have its own required estoppel form, so compare the two and adapt this to your lease and your state.

FAQ
Questions, answered.
What is an estoppel certificate?
It is a signed statement in which a tenant confirms the key facts of its lease - the rent, the term, the security deposit, any amendments, and whether anyone is in default - to a buyer or lender who is about to rely on them. The name comes from the doctrine of estoppel: once you certify a fact and someone acts on it, you are generally barred from later claiming it was different. It confirms the lease, it does not change it.
Who signs an estoppel certificate, the landlord or the tenant?
Usually the tenant, which is why it is often called a tenant estoppel certificate. The buyer or lender wants the lease confirmed by the person paying rent rather than by the seller. Landlords can be asked to sign one too, confirming the same facts from their side, but the tenant version is far more common in a sale or refinance.
Do I have to sign an estoppel certificate?
There is generally no standalone law forcing a tenant to sign one. The duty comes from the lease. Most commercial leases include an estoppel clause that requires the tenant to deliver a certificate within a set period after the landlord asks, commonly around 10 days. If your lease has that clause, refusing to sign an accurate certificate can be treated as a default. Residential leases less often include one.
What happens if I do not return it on time?
Check your lease, because the consequence is written there. Many commercial leases say that if you miss the deadline, the landlord's proposed version is deemed correct, or that the landlord may sign the certificate for you as your attorney-in-fact. Some also treat the failure itself as a lease default. That is why you should not sit on the request: respond within the window, and correct anything that is wrong before the clock runs out.
Can an estoppel certificate change my lease?
No. It confirms the lease; it does not amend it. If the certificate and the lease conflict, the lease still governs the relationship between you and your landlord. The risk is different: by signing, you can lose the ability to assert a fact against the buyer or lender who relied on the certificate. So the danger is not that the lease changes, it is that you are held to what you certified even if the lease said otherwise.
What is the difference between an estoppel certificate and an SNDA?
An estoppel certificate confirms the current facts of the lease. An SNDA, which is subordination, non-disturbance, and attornment, governs what happens if the lender forecloses: the tenant's lease ranks behind the mortgage, the lender agrees not to disturb a performing tenant, and the tenant agrees to accept the new owner as landlord. One is a snapshot of today; the other sets the rules for a future foreclosure. Lenders often ask for both.
Is the estoppel certificate available in Word format?
Yes. Download the estoppel certificate as a Word (.docx) file and edit it in Microsoft Word, Google Docs, or Pages. You can also download a PDF or fill it in and sign online.
Can I download the estoppel certificate as a PDF?
Yes. A print-ready PDF is available alongside the Word version. Download either one free, or fill it in and sign online without downloading anything.
