The date the lease agreement was fully signed by all parties.

The execution date establishes when the lease becomes a binding contract, which affects statutes of limitation, estoppel certifications, and amendment sequencing. If multiple amendments exist, knowing the original execution date allows you to determine the correct order of precedence. It also starts the clock on any pre-commencement obligations like security deposit delivery or insurance certificate submission.
Found on the first page of the lease in the preamble (e.g., "This Lease is made and entered into as of...") or near the signature blocks at the end of the document. Sometimes the last signatory date controls.
Lextract uses a combination of AWS Textract OCR and Claude AI to identify and extract the execution date from your lease PDF. The AI searches for 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.
Commencement Date
The date the legal term of the lease officially begins.
Rent Commencement
The date the tenant is legally obligated to begin paying base rent.
Expiration Date
The date the lease term naturally concludes without renewal.
Lease Term (Months)
The total duration of the initial lease term expressed in months.
Possession Date
The date the landlord grants the tenant physical access to the space.
Free Rent Period
The duration during which the tenant is excused from paying base rent.
No. The execution date is when the lease is signed, while the commencement date is when the lease term officially begins. They can be months apart, especially when landlord construction work must be completed before the tenant takes possession.
The execution date is typically the date of the last signature. Some leases specify that the "effective date" controls regardless of when individual parties signed. The abstractor should note both dates if they differ.
