my client has been getting IS since her husband left in 2000, but has never been paid any IS for housing costs. mortgage in husband's name only. client believes she gave DWP details of mortgage when made her IS claim + we are going to write to ask DWP for review of her claim and copy of her claim forms.
i understand that IS can be paid for housing costs as client has taken on responsibility for them to stay in her home. the question is how can client provide info to DWP about mortgage costs as mortgage company are refusing to accept any contact from her. any experiences of how the DWP process this kind of problem?
many thanks

This is a new one to me, but does your client know what the current outstnding mortgage is and the interest charged?

If that is so, then you could rely on R(I)2/51 and R(SB)33/85 which held that there is no need for corroboration in English law, and that if the circumstances justify it, the claimants word can be accepted.

On the other hand, you could always cite S35 of the Data Protection Act to the lender. S35 provides that data is exempt from the non disclosure provisons if it is needed for the purposes of establishing, exercising or defending legal rights.
