Now grandma would actually like to transfer the house to one of her children so that the house stays in the family, because other children cannot afford to pay for/buy it and poor granny needs money. Notary says need a new transfer, costs same 32jt.
There's no way to do this with only one name change transaction, perhaps avoiding one step of inheritance/sale taxes in the way? 64jt is quite a bit of money already.
I know absolutely nothing about indonesian inheritance law (the family are all muslim), tried to search the forum but found nothing relevant.
