The majority of Land these days is registered at the Land Registry, so you are unlikely to ever receive paper bundles of ‘Title Deeds’ as was formerly the case.
At its most basic The Title Deed confirms the property itself exists, ownership of the property and anyone who has lent money against the property, such as the mortgage lender. You can obtain copies from the Land Registry for a small fee.
The Transfer Deed (TR1) is a legal document that is used to transfer ownership of the property from the seller to the buyer. The Transfer Deed must be completed and signed by both the seller and the buyer, and must be accompanied by a copy of the title deeds for the property.
