Preparing estoppel certificates requires quickly pulling the key terms from the executed lease — tenant name, premise, rent, term, and option status — to confirm against the tenant's representations. Without extraction tooling, attorneys spend hours re-reading leases to populate each estoppel form.
Upload the executed lease and any amendments for each tenant requiring an estoppel.
Lextract extracts tenant name, premises, commencement date, expiration date, base rent, any pending rent modifications, security deposit amount, and option status.
Confirm that all amendments have been uploaded and that the option exercise status matches the current record.
Use the extracted data to populate the estoppel certificate form. Source page references allow the preparer to cite the specific lease clause for each representation.
