The field office (FO) sends an update after transfer (UAT) to the disability hearing
unit (DHU) when the beneficiary (or recipient) or representative updates the FO with
a change of address. The FO notifies the DHU by telephone if a disability hearing
is scheduled and the change of address involves a change in the disability determination
services (DDS) or DHU site.
The DDS sends written confirmation to the DHU and FO when the beneficiary (or recipient)
or representative updates the DDS with a change of address.
