I'm afraid I can't answer your specific question but I do know that there is a discussion of Mortgage Indemnity Guarantees (MIGs) - which you call 'indemnity insurance' [I guess they're the same] - on this HRP site. If memory serves it's to be found in the 'Repossession' section, in the piece headed 'Why lenders refuse to supply documents'.(posted 8511 days ago)
