One blank says defaults. It is printed as none. You are deciding if that is accurate. The paper sits flat on your kitchen table, a half-empty mug of black coffee sweating next to its top right corner. You only pulled this lease exhibit out 10 minutes ago, after your broker sent a three-word text: Check estoppel first. You don’t want to sign off on a lie that comes back to cost you six figures down the line.
Your currently held estoppel page
This is one of seven pages in the estoppel packet your landlord’s property manager sent last week, pre-filled for your signature as part of the pending sale of the industrial building you lease for your product assembly and storage operations. Estoppels are standard in all commercial property transactions, designed to confirm for the incoming buyer that all lease terms and outstanding obligations are documented accurately, with no unstated claims from either party. You scanned the first six pages quickly this morning: base rent matches your monthly auto-pay amount, security deposit listing is correct, lease end date and renewal option terms align exactly with the copy of your original lease you keep pinned above your desk. Every entry checks out except for that single defaults line, pre-filled with the word “none” that you can’t stop staring at. Three weeks ago, you submitted an official written request to the property manager to fix the broken HVAC unit in your second-floor warehouse space, a repair your lease explicitly lists as a mandatory landlord responsibility, with a required turnaround of 10 business days from notification. That window passed seven days ago, and the unit still blows warm air, putting your temperature-sensitive inventory at risk of spoilage. That unaddressed repair is an official landlord default, even if the property manager chose not to list it on the pre-filled form.

One line that dictates future financial exposure
This single line carries more weight than almost any other entry on the entire estoppel, because signing off that there are no defaults waives your right to claim any pre-existing default against current or future landlords for the rest of your lease term. You don’t confirm this line for the benefit of the seller or lender: you verify it for yourself, to ensure you don’t give up access to remedies you are owed under your lease agreement. If you sign the line as written, the incoming property owner has no obligation to honor your HVAC repair request, because there is no official record of the default existing before the sale closed. Illustrative example: If the HVAC unit requires a full replacement costing $18,200, and you have 17 months left on your lease, you could end up covering the entire cost out of your operating budget if you waive the default claim now, because the new owner has no requirement to address an issue you stated did not exist. This line also covers any unstated rent abatements, repair credits, or other informal agreements you made with the current landlord that were not added as formal lease addenda. If you agreed to a 10% rent credit for three months in exchange for covering the cost of repainting the loading dock earlier this year, and the landlord has not yet applied that credit to your account, that counts as a default that you need to list here to ensure you receive the credit after the property changes hands. Any default you do not list on this line is effectively erased from the official lease record once you sign, so accuracy here directly impacts your bottom line for the rest of your time in the space.
Where you mark corrections on the document
You do not need to ask permission to correct an inaccurate entry on an estoppel, because you are only signing to confirm factual details that are verifiable via your lease and communication records. If a pre-filled entry does not match the reality of your lease agreement, you can mark the correction directly on the document before you sign, using the following steps:
- Cross out the pre-filled “none” entry in the defaults blank using a blue or black pen, pressing firmly enough that the cross-out is legible and no part of the original “none” text is visible after marking. Do not use white-out, as that can raise questions about tampering later on.
- Write a clear, factual description of the outstanding default next to the crossed-out entry, including the date you notified the landlord, the specific issue, and the section of your lease that defines the issue as a default. For the HVAC issue, you would write: “Landlord is in default of Section 12.3 of the original lease dated 10/14/2021, as landlord failed to complete repairs of the second-floor warehouse HVAC unit within the 10 business day window required after official tenant notification submitted 4/18/2024.” Avoid subjective language like “the landlord is ignoring my requests” and stick exclusively to verifiable facts.
- Initial and date the change directly next to your written entry, so any party reviewing the document later can confirm you made the edit and when you made it. Use the same initials you use to sign official legal documents, and write the full date including month, day, and year to eliminate any ambiguity.
- Attach a copy of your original written notification to the landlord as an addendum to the estoppel, and note the addendum in the margin next to your entry, writing “See attached Addendum B for supporting notification records”. This gives any future party reviewing the document immediate access to proof of your claim, so you don’t have to dig up old emails to prove the default exists.
You can cross-reference the default definition in your original lease stored in your Lease Jacket dashboard to make sure your written description aligns exactly with the lease terms, so there is no room for interpretation later on. If the landlord pushes back on your correction, you can share the attached notification records to confirm the default is legitimate before you sign the full document.
The next time you open this same page
The next time you open this same page, you hold it next to the fully executed estoppel copy returned by the title company after the property sale closes. You run your finger along the defaults line first, confirming your handwritten correction, initials, and date are all still visible, unaltered, and matched exactly across both copies. You flip to the back of the executed packet to confirm your attached notification records are still included, marked as Addendum B as you noted in the margin. You file both copies in your locked file cabinet with your original lease documents, so you can pull them in 30 seconds if a new property manager reaches out questioning your request to schedule the HVAC repair. If you ever receive a notice of alleged tenant default in the future, you pull this page first to cross-reference the date of the claim, ensuring no party attempts to hold you responsible for issues that predate your estoppel signature. You also pull this page if you decide to assign your lease to another tenant before your term ends, to confirm all outstanding obligations are documented accurately for the incoming assignee. You only revisit this page when a relevant issue arises, and you never have to guess what terms you agreed to, because you made sure the written record matches the factual reality of your lease obligations on the day you signed. You don’t need to review it on a regular schedule, but you know exactly where to find it if you ever need to reference the official record of pre-existing defaults as of your signing date. Even if the property changes hands three more times before your lease expires, you have tangible proof of the unaddressed repair obligation, so you don’t have to negotiate for a remedy you were already owed long before the new owner took over the building.
