Money with the Governments lawyers

My Uncle died in 2005 and leave back his two boys with an 82 year old mother. They were money saved by my uncle money via Bank and that money was taken by the state lawyer to distribute it to beneficials which never happened. The state lawyer died before this money reach the beneficials and when continue with the process to obtain this money it was found out that the state lawyer was not registered and he was working with fault qualification. State lawyers properties and asset were frozen and now it been years without getting any help from any one. I kindly request that who ever can assist in this matter come forward and help. My grandmother is 82 years old now and my cousins are in the University (MUT) doing well and lastly these kids don't have both parents as they are late.
