Ont,
Not sure of the terms of your separation agreement, but was this meant to be dental and extended health benefit and or life insurance in general.
You may want to point out to your ex that support orders in Ontario bind estates unless otherwise stated. I suspect that if your separation agreement is silent on support on death of the payer, I would think the law would prevail.
Depends on the language used in your separation agreement.
as listed in the Family Law Act R.S.0 1990
Section 34 subsection 4
Support order binds estate
(4) An order for support binds the estate of the person having the support obligation unless the order provides otherwise. R.S.O. 1990, c. F.3, s. 34 (4).
