The Unclaimed Financial Assets Authority (UFAA) has asked Azimio La Umoja party leader, Raila Odinga, to collect millions left behind by his son, the late Fidel Odinga.
Head of Corporate Communications, Paul Muya, stated that Raila had yet to make an official money claim.
UFAA, however, withheld information on the companies that surrendered the multi-million fortune.
It petitioned the family to collect the dues arguing that the authority was already overwhelmed by the huge amount of idle assets running into billions.
"We are asking the families and beneficiaries to come forward for the unclaimed money, which is substantial,” Muya remarked.
A report indicated that Fidel left behind a fortune, including cash in eight bank accounts and two investment funds.
Muya told the Standard that most of the unclaimed assets belonged to members of prominent families, including that of former Cabinet Minister, Njenga Karume.
Others included renowned politician John Harun Mwau and the late prolific American writer and scholar, Ali Mazrui, who was born in the country.
On March 28, the authority's chief executive officer, John Mwangi, disclosed that the state was in possession of wealth totalling Ksh54.9 billion.
The property was in the form of unpaid insurance policies, mobile money in wallet accounts, unpaid pension remittances, money in bank accounts, Saccos and legal reparations.
Consequently, the state agency launched a project to enable Kenyans to access information on assets from Huduma centres across the country.
Kenyans can also check their status through their mobile phones by dialing the USSD code *361#.
