I live in BC Canada. I am 65 yrs of age.

I have been separated from my wife for 11 plus years but never legally divorced. I have been living common law with someone for the entire 11 plus years..My wife will contest the divorce proceedings stating that if i file for divorce she will claim child support for our 19 yr old daughter who is in university (but only if i file for divorce does she want support). My question is, If I were to die without being legally divorced (I have stage 4 cancer), who is entitled to my CPP death benefits, survivor benefit and my joint assets (joint with my common law wife)? Is my common law partner or my wife who i have been separated from for over 11 years entitled to these benefits?
