Estate planning doesn't just mean doing a will. It means learning how property transfers with or without a will and making sure you have set up your financial affairs so that your property goes to the people or charities that are important to you.
There can also be some tax planning involved. Most people don't have to worry about Federal Estate Tax anymore since you don't pay taxes unless you have an estate over 5 million dollars. However Oregon still begins to charge estate taxes on estates of 1 million dollars or more.
