Misidentifying the landlord entity can invalidate lease enforcement, rent payments, and legal notices. If the landlord is a single-purpose LLC that later dissolves, the tenant needs to know the exact entity to pursue remedies or negotiate amendments. Accurate entity identification also matters for estoppel certificates and SNDA agreements during property sales.
Typically on the first page of the lease in the preamble or recitals section, immediately following "This Lease Agreement" language. May also appear in the signature block at the end of the document.
Lextract uses a combination of AWS Textract OCR and Claude AI to identify and extract the landlord name from your lease PDF. The AI searches for the field name and common aliases like "Lessor", "Landlord" across all pages of the document, then assigns a confidence score based on OCR quality and extraction certainty. Fields with lower confidence are flagged for human review.
Tenant Name
The legal corporate entity leasing the premises.
Guarantor Name
The entity or individual providing financial backing for the tenant.
Premises Address
The full physical address of the leased space.
Suite/Unit Number
The specific identifier for the tenant's space within a multi-tenant building.
Rentable Area (RSF)
The total area for which the tenant pays rent, including common area allocations.
Usable Area (USF)
The exact private physical space occupied by the tenant.
The landlord entity determines who is legally responsible for maintenance obligations, security deposit returns, and honoring lease options. If the entity listed is a holding company with no assets, the tenant may have limited recourse if the landlord breaches the lease.
Most leases include a provision allowing the landlord to assign its interest to a new owner. The tenant should verify that the new owner formally assumes all landlord obligations. An SNDA agreement with the lender provides additional protection during ownership transitions.
