Nine Fields, Every One Auditable.
Each extraction is a citation, not a guess. The model returns the source page reference alongside every value, so your legal team can spot-check faster than it takes to make tea.
Term dates
Start, end, rent-commencement, holdover detection. Computed termEnd from 'X years from termStart' clauses; LR1 verified.
Break clauses
Rolling, fixed-date, conditional. Notice periods extracted with the date; we alert your team 90 days before each window.
Rent reviews
Open-market, RPI, CPI, fixed uplifts. Pulled from the rent schedule and any 'Rent Review' clause, every date page-cited.
Service charge cap
Cap value, indexation basis, applicable years. Reconciliation alerts when the cap nears the actual demand.
Alienation regime
Assignment, underletting, sharing-of-occupation rules. Qualified vs unqualified consent flagged for legal review.
Repairing obligation
FRI vs IRI vs other. Plus any limits on liability — caps on dilapidations, schedule of condition references.
LTA 1954 status
Excluded vs retained. Pulled from the schedule of exclusions; flagged on the lease detail page for renewal planning.
Permitted use & planning
Use class (E, F1, B1, etc), planning reference, change-of-use restrictions extracted from the user clauses.
Source-page citations
Every extracted value links back to the page it came from. Re-extract on demand if your lease has been amended.
