A preparation checklist for reviewing and responding to landlord-requested estoppel certificates. This checklist ensures tenants verify all statements against the lease before certifying, protecting against inadvertently confirming incorrect facts. It also guides tenants on appropriate qualifications and exceptions to include in the estoppel response.

Used by tenant legal counsel, real estate managers, and lease administrators when a landlord requests an estoppel certificate in connection with a property sale, refinancing, or lender due diligence.

An estoppel certificate is a legal document in which the tenant certifies specific facts about the lease — including rent amounts, lease dates, the absence of landlord defaults, and the completeness of the lease agreement. Once signed, the tenant is estopped (legally prevented) from later claiming facts that contradict the certificate. Lenders and buyers rely on estoppels to confirm the economic and legal status of leases in a property acquisition.
Most commercial leases require the tenant to provide estoppels within a specified timeframe (typically 10-15 days) upon landlord request. Unreasonably refusing to sign is typically a default under the lease. However, you can and should include qualifications for any statements you cannot independently verify, and you should note any outstanding landlord defaults or disputes.
Never sign an estoppel containing incorrect facts without modification. Strike the incorrect statement, write in the correct information, and initial the change. If the landlord prepared the form, send a red-lined version with your corrections. Signing a materially incorrect estoppel can waive important lease rights and bind you to unfavorable terms.
