Even though others think your question is a “fake” question, nevertheless, it’s an important and extremely valid question. If your father is going to marry a woman in her thirties or childbearing age, make sure that you and your siblings sit down together and discuss your inheritance from your parents’ side. Make sure that he has already made a Will stipulating who is going to inherit your parental home, his savings in the bank and other important items of considerable value, sentimental or pecuniary. Because if you people haven’t done this yet, you will lose your entire inheritance, once his second wife has 3 - 4 children with him. In fact, this happened to my best friend, when we were all at university and living in the halls! I hope he will come forward and confirm what I am saying. He is on this forum too, just like many other friends of mine at university. Be diplomatic as well as shrewd about it all just like the Chinese
After all, your poor mother didn’t work so hard when she was alive, to have everything passed on to his new wife and children; basically a new family!!! Take care of your financial side quickly!
