Scotland: HMRC Form C5 (Info.about Small Estates)

I was denied a copy of Form C5 from Solicitors, although one of the Executors ie First Executrix. My now "estranged" Sibling (living locally and having no health problems like myself) held Power of Attorney. I was the substitute P.O.A. My Sibling admitted to gifting herself "no more" than £3k. I believe that to have been per annum and so quite a considerable sum. I received no gifts, although the P.O.A. was designed to allow that. I am in the process of complaining to the S.L.C.C. about the Solicitors on many levels eg I have evidence they had been instructed by my Sibling in the past. I have two queries; 1) I would like to contact the HMRC for a C5 copy and would like to know the Dept.and Address please 2) Although I did not give or sign my consent, I feel she may have been flying solo as the Personal Representative of the Estate, via a Banking Institution that only allow one Pers.Reps. and I'm looking into this matter. Meanwhile, if she was, would a different form to the C5 have been submitted and what would this form be called and which Dept. and Address would that be please ?
