Just because a life insurance payout does not generally go through probate does not mean the non-probate asset is not reported to the probate court.
Generally, if the beneficiary on the policy is the estate, then the insurance company must directly pay the probate court. The court first uses said money to pay associated legal costs, like court fees. Afterward, it distributes whatever amount is left according to the deceased’s will.
Also, if Paul was the beneficiary of Maggie's life insurance, this would become a probate asset: Paul is deceased and died without a Will.
