Sharing parent's inheritance with sister?

Questioner

My parents had 2 children. After my father passed away 21 years ago, it was necessary to support my mother financially. I did this for 21 years in the form of either transferring money or giving cash and I paid certain bills. My mother recently passed away and has no will. My question is: am I entitled to the part of the money that I transferred to my mine. I can look back on her giro account for 12 years and therefore prove a part. Or should I share all the money 50/50 with my sister.

Lawyer

You have voluntarily supported your mother without any obligation in the form of alimony. This cannot be offset now with the opening of the inheritance.
