If compensation to a beneficiary is terminated, the amount of
compensation payable to one or more of the remaining beneficiaries may
be reapportioned. Similarly, the birth of a posthumous child may result
in a reapportionment of the amount of compensation payable to other
beneficiaries. The parent, or someone acting on the child's behalf,
shall promptly notify OWCP of the birth and submit a copy of the birth
certificate.
