1. Don't attach too many strings. According to the article, one of the chief aims of estate planning should be to avoid leaving a legacy of ill will. By attaching too many strings, such as mandating that a grandchild use trust funds only for tuition at a specific university or go into a certain occupation, you are increasing your chances of there being ill will among your heirs.
2. Make special arrangements for beloved properties. Do you have a family cottage on the lake in Northern Michigan? If so, what will happen to it upon your passing? There are many options, such as dictating that it be appraised and listed for sale, kept in the family, create a family LLC to manage and maintain the property (and schedule who gets to use it when), or distributed outright to the heirs and letting them figure it out.
