Unless you buy your apartment as a new build, straight from the developer, it won’t be.
The original parties are shown on the lease and remain throughout. The lease document itself is not updated on sale.
It is HM Land Registry that is updated when you acquire a property whether it is freehold or leasehold.
Conveyancers call the Land Registry entries office copies of the register.
Essentially the office copies are the deeds. You no longer receive a bundle of historic paper deeds. The office copies are a summary of the old paper deeds and show current owner and lender.
