if the id card of your late father is valid, contact an agent transfer the car under your mother's name.
sell it later.
if you choose the method mentioned in blog, you will be in a spin for very long time. It is a moveable asset and can be managed in plain sight. am sure no heir will have an objection for transfer to sell later for distribution of heirship by mother., unless the mother feels unsafe and become biased for an individual.
am sorry for being so arrogantly rude, however am going through such mediation. Nobody was willing to trust anyone, so the vehicle is transferred to my mother - no blood relation but just old time neighbor (all agreed signed the paper). Vehicle is up for sale am expecting deal closed by Friday. My mother will distribute the money among 1 widow and 5 orphans (3 boys & 2 girls) through the bank cheque.
