In fact, whether your parents are divorced or your custody is awarded to your father or mother, it doesn't affect whether you are your parents' child. According to the inheritance law, as a child, you are naturally the legal heir of your parents' property. Therefore, of course you have the right to inherit your father's property.

At the same time, according to the inheritance law, your grandparents are still alive, ranking first like you, and they are all legal heirs of your father. Therefore, your grandparents also have the right to inherit your father's property.

If there are no special circumstances, the property is divided into three parts, and your grandparents and you each get one-third of the inheritance. Of course, this is a theoretical division method. The specific division can be resolved through consultation with grandparents. If negotiation fails, the only legal procedure is to file an inheritance lawsuit with the grass-roots court where the property is located.
