41 C.F.R. § 303-70.500
Relocation of immediate family after employee's death outside continental United States (OCONUS)
Agencies must return the immediate family, baggage, privately owned vehicle (POV), and household goods to the former residence, or transport them to the new official station CONUS, or to an alternate destination, if the immediate family chooses to continue relocation (see § 303-70.501). Travel and transportation must begin within one year from the date of the employee's death. A one-year extension may be granted if requested by the immediate family prior to the expiration of the one-year limit. The agency head or designated representative may approve the immediate family's relocation.
