In that case, no it is not usual. All they need to do is write to the asset holders and creditors and assess the value of the estate, calculate any IHT due and then prepare the documents for a Grant (and oath and IHT account). Sounds ridiculous. I would strongly suggest you go somewhere else. You should be able to get someone to do it on a pure hourly rate basis only. Lets face it, if the estate is worth �1m, they will be paid �10k for filling in a few forms. Go elsewhere.
