Hi geoff and welcome to the forum
If your brother in law is not happy with the service he is currently receiving, then suggest he gets a second opinion before he parts with any more money. He should not need to pay anything further until an IVA is in place.
I have an article on my blog which gives tips about choosing an advisor, so he may like to have a read of that before proceeding further. As he is in HM Armed Forces, do ensure that whoever he chooses has experience of dealing with such cases, and understands that a greater degree of flexibility is required as a result of changing postings and operational tours.
