Everyone has heard the terms "will" and "trust," but not everyone knows the differences between the two. Both are useful estate planning devices that serve different purposes, and both can work together to create a complete estate plan.

One main difference between a will and a trust is that a will goes into effect only after you die, while a trust takes effect as soon as you create it. A will is a document that directs who will receive your property at your death and it appoints a legal representative to carry out your wishes. By contrast, a trust can be used to begin distributing property before death, at death or afterwards. A trust is a legal arrangement through which one person (or an institution, such as a bank or law firm), called a "trustee," holds legal title to property for another person, called a "beneficiary." A trust usually has two types of beneficiaries -- one set that receives income from the trust during their lives and another set that receives whatever is left over after the first set of beneficiaries dies.
