A lease rarely lives alone. Over its life it accumulates variations, consents, assignments and, at the freehold, transfers. Proprietas reads these lease-adjacent deeds too, so the full paper trail is in one place. ## Recognised Deeds | Deed | What it does | | ---------------------- | -------------------------------------------------------------- | | Licence to alter | Landlord consent for tenant alterations | | Deed of variation | Amends an existing lease | | Rent review memorandum | Records a rent review outcome | | Assignment | Transfers a lease from assignor to assignee | | Surrender | Tenant returns the lease to the landlord | | Wayleave | Grants access for utilities or cabling | | TR1 | HM Land Registry transfer of whole — a freehold/title transfer | ## What's Extracted For each deed, Proprietas pulls the **parties**, the **effective date**, the **premises** it concerns, the **original lease date** it relates to, and a one-paragraph plain-English summary of the operative clause — so you can see what a deed does without reading all of it. **TR1 transfers** additionally capture the **title number** and the **consideration** (purchase price), because a land-registry transfer is about the title, not a tenancy. ## Why It Matters Keeping deeds beside the lease means a break notice, a varied rent or a change of tenant is never a surprise buried in a separate folder. When you assign or vary a lease, the chain is intact — useful for portfolio diligence and for proving the current position to a buyer or auditor. Back to how leases themselves are read.
