In our divorce papers it states that he/I are suppose to name our children as benificiaries on any life insurance policies or retirement funds.
Honestly, there are a LOT of problems with such broad language in a decree.
First, while it makes sense to allocate a specific insurance policy or asset to have you or the children named as beneficiary, the idea of any and all policies or retirement funds that he might have ever added in the future being only designated to the kids of a first marriage is legally problematic. Future spouses or children are also entitled to their share of a decedant's estate, and a future spouse has a legal, marital right to retirement funds that may accrue during their marriage (it didn't happen, but it could have). And one can't prohibit future additional policies from naming other parties as beneficiaries.
Seems to me that each divorcing parent should own a policy against the other's life. That way, they as owner control both beneficiary designation and whether it is allowed to default. I'll never understand why more women don't just buy and own policies against their spouse. Obviously, they need to both be in the loop at the time the policy is purchased.
