An estoppel certificate is a short statement, signed by a tenant, confirming the basic facts of their tenancy: what the rent is, what has been paid, what the landlord still owes them and what side agreements exist. It is requested when a building is being sold or refinanced, because a buyer or a lender is about to rely on a rent roll and wants the people actually paying the rent to confirm it. This page is about what it asks and why the answers matter.
Who asks, and what they are protecting against
A buyer inherits the leases along with the building, and a rent roll is the seller's account of them. The estoppel is the tenant's account of the same facts, and where the two differ the difference is usually something the seller forgot rather than something concealed: a concession granted verbally, a repair promised, a deposit held in an amount nobody wrote down. Finding those before closing is the whole point.
The four answers that matter
The current rent and when it was last changed. Whether rent is paid to date and whether anything is in arrears. What deposit the landlord holds. And whether any agreement exists that is not in the written lease. The last one is where the surprises live, because an informal arrangement made two managers ago is invisible to the rent roll and entirely visible to the tenant living under it.
Why the word estoppel
Once a tenant has confirmed a fact in writing and a buyer has relied on it, the tenant is generally stopped from asserting the opposite later. That is the mechanism, and it is also why a tenant should read one carefully rather than sign it as a formality: confirming a rent figure that is wrong is not a clerical error afterwards. A landlord asking for one should expect and welcome the questions.
What makes them painless to produce
A landlord who can already produce, per unit, the lease with its dates, the rent charged and received, the deposit held and any addenda, can fill an estoppel request in minutes. A landlord reconstructing that from email cannot, and the delay is visible to the buyer at exactly the moment they are deciding how much diligence the rest of the file needs. The record is the preparation.
Questions people ask about estoppel certificate
Is a tenant obliged to sign one?
It depends on the lease. Many commercial and some residential leases contain a clause requiring the tenant to return an estoppel within a set number of days on request; without such a clause it is a request, not a requirement.
What happens if a tenant refuses?
Lenders and buyers usually proceed on the landlord's certification instead, with more caution and sometimes a holdback. A refusal is not fatal, but a pattern of them reads as a problem with the building rather than with the tenants.
Does an estoppel change the lease?
No. It confirms what the lease and the tenancy already are. If it appears to change something, that is a sign the written lease and the lived arrangement have drifted apart, which is the thing worth fixing.
