In general, a subrogation heir can only inherit the share of the estate that his father or mother is entitled to. If a successor in subrogation lacks the ability to work and has no source of income, or has made major contributions to the decedent, he may share more of the estate when distributing it.
 However, if the successor has lost the right of inheritance, his lineal descendants may not inherit in subrogation. If the successor in subrogation lacks labor and has no source of income, or has more obligations to support the decedent, it can be properly distributed to the estate.
 [Legal basis] According to Article 1128 of the Civil Code, if the children of the decedent die before the decedent, the direct younger blood relatives of the decedent's children shall inherit in subrogation.
 If the decedent's brother or sister dies before the decedent, the children of the decedent's brother or sister shall inherit in subrogation. The successor in subrogation can generally inherit only the share of the estate that the successor in subrogation is entitled to inherit.
