Typically, you will owe your spouse the value of 50% of your pension that was earned during the marriage. If you wish to retain the entirety of your pension - you will need to reach an agreement where this owed value is offset by other assets. For example, if your spouse would be entitled to $100,000 of your pension and you jointly own a home valued at $200,000 - you can choose to allow your spouse to retain the entirety of the value of this home, in exchange for keeping your entire pension.
