Substitution of heir refers to the appointment of another heir for the purpose of inheritance in default of a heir who originally instituted the suit. It is well-settled that the object of substitution of heir after the death of a party in the suit is only for the purpose of bringing the legal representative for continuing and conducting the legal proceeding. It does not decide inters dispute between the claimant nor does it operate as res judicata in a subsequent dispute between the several claimants.
