A trust is a legal mechanism that lets you put conditions on how your assets are distributed after you die and it often lets you minimize gift and estate taxes. But you still need a will since most trusts deal only with specific assets such as life insurance or a piece of property, but not the sum total of your holdings.
Even if you have what’s known as a revocable living trust in which you can put the bulk of your assets, you still need what’s known as a pour-over will. In addition to letting you name a guardian for your children, a pour-over will ensures that all the assets you intended to put into the trust are put there even if you fail to retitle some of them before your death.
Any assets that are not retitled in the name of the trust are considered subject to probate. As a result, if you haven’t specified in a will who should get those assets, a court may decide to distribute them to heirs whom you may not have chosen.
