To fill out a tenant estoppel certificate, work through the landlord’s pre-filled draft line by line with your lease and every amendment in front of you, confirm each fact, correct anything wrong by marking the document and initialing the change, and return it before the deadline in your lease. The form is a legally binding statement of what your lease currently says, and a signed certificate can override the lease itself if the two conflict, so accuracy matters more than speed.
Gather Your Documents First
Before you write anything on the form, pull the original lease, every amendment, any side letters, and any written correspondence about repairs, allowances, or unresolved landlord obligations. The certificate asks you to certify facts, not recollections. If you signed three amendments and the form only references the original lease, you need the amendments in hand to add them. If the landlord still owes you a construction allowance or an unfinished build-out, you need the paperwork that proves it.
Landlords almost always deliver the form pre-filled. Your job is verification, not drafting. Treat every printed answer as a claim you are being asked to confirm under signature.
Lease Identification and Dates
The top section identifies the lease. Confirm that the landlord and tenant names appear exactly as they read on the lease, that the property address and suite or unit number are right, and that the commencement and expiration dates match the current state of the lease, not the original term.1AIR CRE. Estoppel Certificate Form If you have renewed or extended, the current expiration date must reflect that.
List every amendment by date so the full history is traceable. Some forms also ask whether you hold remaining renewal options or a right of first refusal to purchase the property. Answer those. Omitting a renewal option does not legally cancel it, but it invites disputes with a new owner who bought the building believing your lease ends sooner than it does.
Rent and Financial Terms
This is the section a lender or buyer will scrutinize most closely. Enter the current monthly base rent (not an outdated figure and not a future escalation), the day of the month it is due, and the date through which rent has been paid.2AIR CRE. Standard Estoppel Certificate – By Lessor
If you pay additional amounts for common area maintenance, property taxes, or insurance (often called pass-throughs or triple net charges), list each one separately with its current amount. Forms typically include a blanket statement that no rent has been prepaid beyond what the lease reflects. If you have prepaid anything, cross out that statement and write in the actual prepayment details.1AIR CRE. Estoppel Certificate Form
Security Deposit
Enter the exact dollar amount the landlord currently holds.1AIR CRE. Estoppel Certificate Form If any portion has been applied to past-due rent or damages, put the reduced figure and briefly explain what happened. Do not repeat the original number from years ago if it no longer reflects what the landlord holds. If the deposit is in a separate escrow account, note it.
Defaults and Outstanding Landlord Obligations
This is where most of the risk lives for tenants, and it is the single most important part of the form to get right.
The certificate will ask whether either party is currently in default. If the landlord owes you anything, disclose it here: unfinished build-out work, an unpaid construction or tenant improvement allowance, overdue repairs, an HVAC problem the landlord agreed to fix, a parking allocation never delivered. The same goes for any ongoing disputes, pending claims, or offsets you are taking against rent.
Signing a certificate that says “no defaults” when defaults exist can permanently waive your right to enforce those obligations against a new owner. Courts treat the certificate as evidence, and a new landlord who bought the building relying on your signed statement is generally not bound by problems you failed to disclose. By omitting a landlord default from the estoppel, you can lose the ability to enforce that lease provision entirely.
Verbal side agreements need the same treatment. Designated parking spaces, after-hours access, storage areas, or a handshake deal on maintenance responsibilities should be written into the certificate if you want them to survive a sale. A new owner is not bound by arrangements that appear nowhere in the lease or the estoppel.
Cross-Check the Pre-Filled Form Line by Line
Before you sign, run through the draft against your documents:
- Base rent matches your current payment, not an outdated figure or an upcoming escalation.
- Expiration date reflects any extensions or renewals you have exercised.
- Every amendment is listed. If the form references only the original lease and you have signed three amendments, add them.
- Remaining renewal options and any right of first refusal are stated.
- Security deposit amount is what the landlord actually holds today.
- Pass-through charges (CAM, taxes, insurance) match your current invoices.
- The default section reflects reality, including any unfinished landlord obligations.
How to Correct and Return the Form
If something on the pre-filled form is wrong, do not refuse to sign and do not leave it and hope the deadline passes. Mark the corrections directly on the document, initial each change, sign the certificate as corrected, and return it. Some transactions require notarization. Check the requesting party’s instructions and your lease language, because lenders sometimes insist on a notarized signature even when the lease does not.
The landlord typically delivers the form by certified mail or through a document platform that logs receipt. The completed certificate goes back to the buyer or lender, who will compare your figures against the landlord’s rent roll and the lease file. Any discrepancy needs to be resolved before closing or loan funding.
Watch the Deadline
Commercial leases usually give the tenant a set window to return the signed certificate, often ten to fifteen business days from receipt. Missing that deadline can be treated as a lease default and expose you to whatever remedies the default clause allows, including, in some cases, termination.
Many leases also include a “deemed approval” clause: if you do not return the certificate on time, the facts in the landlord’s draft are treated as confirmed, and you are bound by whatever the landlord wrote, whether accurate or not. Courts in some jurisdictions have limited these clauses when the landlord’s draft contains statements the landlord knew were wrong, but that protection is not universal. The reliable move is to review, correct, and return the certificate on time, not to test how far a deemed-approval clause will reach.
If an SNDA Arrives With the Estoppel
Buyers and lenders sometimes send an estoppel certificate together with a Subordination, Non-Disturbance, and Attornment agreement. They are different documents and should be handled separately. The estoppel confirms existing facts about the lease and creates no new rights. The SNDA is a forward-looking agreement among tenant, landlord, and lender that governs what happens if the landlord defaults on the mortgage and the lender forecloses; without its non-disturbance piece, a tenant whose lease is subordinate to the mortgage can lose occupancy rights after a foreclosure. Confirm facts on the estoppel; negotiate terms on the SNDA.
