I am not angry or bitter. That would be my pot head brother who was living in mom's basement until evicted for financial and physical elder abuse. I am quite content, despite a fatal diagnosis. Two children with debt free PhDs. We never had a problem paying off mortgages within a decade. Gold Collar IT jobs. 

My parents have criminal records, which is an objective reality check. 

I told my siblings that I am not interested in any equity left in our mother's home. I regard it as tainted money and feel that if we get the spend rate just right it could last just as long as she needs care in a seniors care facility. If there is any left afterwards we got it wrong.

Pot Head tried to get her to make him the sole heir, which raised concerns, particularly after my sister got a call saying  that his addict girlfriend had punched our mother. Under BC law courts will do an set formula split if any heir disputes a will, considering any "gifts" transferred before death.
