If you are 95 and own stocks and want to protect your wife, I would consult an estate planning attorney in your area. You should be able to have a simple will drawn up fairly cheaply and quickly. Ask for recommendations from family and friends. Good luck!
A simple will, if that is all you need, can be prepared very quickly and inexpensively. You may also be able to add your wife to the stock certificates as a joint owner with right of survivorship, which would vest the stock into her name immediately upon your death. Call your broker.
