People often assume that estate planning is only for the very wealthy. That it is a means of organizing wealth into complicated funds and trusts. The reality is that estate planning is for everyone. It doesn't require you to have amassed assets and property, it can be as simple as drafting a few pages of legal documents.
Each person's situation is different, but generally speaking there are a few key legal documents that no older person should be without. They cover the basics of what should be done if you are incapacitated and legally state your wishes for your things after passing away. They are often very inexpensive to create and can be drafted in relatively short order.
