Is grandchild inheritance of paternal grandmother's estate possible?

Yes, grandchild inheritance is possible.

If your father is alive, since he is the lineal descendant of the grandmother, he will inherit the grandmother's estate.

In other words, since the father becomes the 1st-priority heir and inherits the grandmother's estate, the grandchild cannot inherit the grandmother's estate.

However, if the father has already passed away, the grandchild becomes a 'substitute heir' and can receive grandchild inheritance.

A substitute heir refers to a person who can inherit in place of the heir if the heir dies or becomes disqualified before the inheritance begins.

In this case, the grandchild inherits the grandmother's estate in place of the father.

How inheritance proceeds is determined by the order of inheritance.

Inheritance proceeds in priority order, and if there is an heir of one priority, the next-priority heir cannot inherit.

The order of inheritance is as follows.

1. Lineal descendants (children, etc.) and legal spouse

2. Lineal ascendants (parents, etc.) and legal spouse

3. Siblings

4. Collateral relatives within the 4th degree (aunts, etc.)
