Check every field
Confirm you recognise each product and lender, the amounts owed and your role (borrower or guarantor), and look for any amount in default.
Dispute errors with the reporting entity
Ask the lender that reported the information to correct it; it is responsible for the data.
Act early if payments slip
Tell your lender in writing if you are in arrears and ask to be placed in PERSI.
