We're in the middle of this too. My Mam passed last October and I just got the probate through. The house isn't an issue as my sister will have it, but it's the little things that break your heart. Photos and momentoes are hard, but I found myself sitting on the kitchen floor holding a puddin' tin she had made countless 'Yorkshires' in. It was so symbolic of her love for all of us, I was in bits. This is part of the process though, and letting go of the things is part of letting go of the person. Take your time and allow your memories free reign is my advice.
