What it does not tell you
A title document will not usually show the current mortgage balance, repayment history, interest rate or private finance details. It is a property title record, not a credit report.
What to order
Order the Title Register if you want to check registered charge or lender information. The Title Plan is not usually the document used for mortgage entries.
