Life insurance beneficiary

[k1972]

My husband has life insurance through his employer and I'm currently listed as his beneficiary. We have two children. After we divorce should the policy still list me as the beneficiary or should it be changed to be in the children's names? Since they are both under 18 I don't believe that's possible. Would we have to be listed as co-beneficiaries? We are filing the divorce papers on our own, so I'm not sure how to word it in the separation agreement.
