In the commercial real estate sector, the tenants are continuously requested by landlords to complete an estoppel certificate form that will be in favor of the lenders as to the status of their leases. An estoppel certificate must be signed by a tenant where the written lease contains a provision that is required to be done by the tenant. These provisions that lay down the rights of the tenant in a rental agreement is known as estoppel certificate addendums.

What is an Estoppel Certificate?

A certified statement that has to be filled by the tenant that verifies the terms and conditions along with the current status of their lease is known as an estoppel certificate. According to its definition, an estoppel certificate addendum is a signed statement by a party certifying for another’s benefit that some facts are correct and that there are no defaults and also that the rent is paid till a specific date. This statement estops that party from later claiming a different state of facts and also provides proof of cash flow which is ultimately what a potential investor or lender in a property is concerned about.

What Does an Estoppel Certificate Include?

It is considered to be a general rule that a tenant would want to limit an estoppel certificate to the facts that cannot be determined through a review of the lease. An estoppel certificate includes the following points:

  • Date when the rent was paid.
  • In case any event has occurred that comprises a default under the lease.
  • If there has been any kind of written amendments to the lease.
  • If the tenant or landlord has notified each other that there is a breach of the lease in some respect.
  • If any rent adjustments are not stated in the lease.
  • In case the tenant has allocated the lease or plans of subletting the premises.
  • In case the tenant starts using any kind of hazardous substances at the rented premises or has violated any kind of environmental laws.
  • Whether or not the security deposit has been paid by the tenant.

Risks of Signing an Estoppel Certificate

Generally, if an estoppel certificate is filled out accurately, then there are no risks to the tenant, however, in cases, if the estoppel certificate is not accurate and does not describe rights that are not compatible with the terms of the lease, unfortunately, there might be some problem. It has also occurred, though it is quite rare, some tenants have also been sued for inaccurate estoppels, primarily in rent-controlled jurisdictions. Till now, we all know that an estoppel certificate is a binding document, therefore, provisions that are inconsistent with the lease should not be included in this certificate.

A tenant must, therefore, be very careful to ensure that every addendum or provision that is listed in the estoppel certificate is accurate and complete. One must also keep in mind that this certificate should not be utilized in place of the lease or agreement itself and should make objections in case any provision that would modify the terms in the lease or limit their rights under the lease. A tenant should also be careful while filling out information on the estoppel certificate that the lease already contains as doing so may result in obscurity if it is completed incorrectly or inaccurately.
