In this case, your Will is not automatically invalidated.  Unless your Will specifically addresses the divorce, your Will shall read as if your ex-partner has passed before you have.  Your ex- spouse will therefore not inherit* as a beneficiary and cannot be named executor. * The exception to this is beneficiary appointments on RRSP’s, TFSA’s, RRIF’s, pensions or insurance.  These will need to be changed explicitly in a new Will or they can be corrected at your local bank or financial institution.   The safest action to protect your assets and wishes is to create a new Will and revoke prior Wills after divorce.
