Can a mother or son contest a death insurance beneficiary if it has a no family beneficiary?

Yes, a mother or son can contest a death insurance beneficiary designation, even if the policy specifies no family beneficiaries. They may argue that they have a legal or equitable interest in the policy or that the designated beneficiary was not validly named. However, the success of such a contest often depends on the specific circumstances and the laws governing insurance policies in the relevant jurisdiction. Legal advice may be necessary to navigate the complexities involved.
