Would you prefer that your assets stay in your own family? Sure - who wants to give their hard earned money and the assets they have accumulated over their lifetime to any person outside of their family? Without an estate plan, your child's spouse may end up with your money. If your child divorces, half of your assets could potentially go to that in-law spouse. With an estate plan, you can set up a trust that ensures that your assets will stay in your family, and pass down to your grandchildren.
