If you have been receiving CPP disability and LTD and after 20 years you apply for a CPP spousal split with an ex-spouse can your long term insurance company claw the added money back if it was applied to your CPP disability monthly benefit? Can not find an answer to this question from anyone.
Is it a higher CPPD amount going forward?
I would assume the insurance company will deduct that.
Do you have to tell the insurance company, probably.
Should you tell the insurance company, that is your call.
If you have many potential years left on it then the risk of being sued for fraud is greater.
