This is why you need to look into things like estate planning. This is a process by which you would end up determining how you are going to divide up your estate amongst your children. One tip for something like this is that you should never try to leave one child a significant amount more than the other. You should try and make sure that all of your children receive more or less equal amounts otherwise there is a very good chance that they are going to end up feeling a little bit like you did not care about all of them equally and this will lead to several disputes after you have passed on which is something that you are obviously not going to want at all.
