Does my wife get half of my CPP in a divorce settlement?

Yes, the general rule is to divide pension benefits earned during the marriage. That means your spouse would be able to get half of your pension. They are limited to what was earned during the period of marriage. If both of you were receiving CPP, then each one of you would get half of all CPP contributions you both made in each year of your relationship. This is called credit splitting. You don't need an agreement or court order to divide your CPP credits.
