Use Form SSA-1129 (Representative Fee Case Past-Due Benefits Summary) (see exhibit in GN 03905.040) to manually calculate the past-due benefits amount in the following situations:

• •

  court cases, when requested;

• •

  administrative review cases in which the reviewing official requests verification of the past-due benefits amount; and

• •

  the Hearing Office (HO) cases when the Administrative Law Judge or Administrative Appeals Judge specifically requests it.

After the PC (or FO for T16) completes the SSA-1129, place the original copy in the claim file and route a copy to the requesting office (the Office of the General Counsel, HO, or the reviewing official). (See GN 03905.040 Representative Fee Case Past-Due Benefits Summary (SSA-1129) - Exhibit.)
