Again I wish people would actually read before posting.

Section 7. How Your Other Beneficiaries Can Use Your RHA
Your Other Beneficiaries
If your Spouse dies or remarries, or if you do not have a surviving Spouse, any remaining balance in your RHA will be divided into separate sub-accounts for your other Beneficiaries. These Beneficiaries will be each of your surviving Dependent children who were designated by you in accordance with the Plan’s Beneficiary designation process. If you have no designated Beneficiary on file on the date of your death, each of your surviving children who were Dependents immediately prior to your death will become a Beneficiary. There are no other default Beneficiaries under the Plan.
