Do You Need a Living Will? - Law and Daily Life
The second document in the plan is called a "pour-over" will. Why do you need a will if you have a trust? The trust can only affect property that is specifically transferred to it. The will acts on any property that is not transferred to the trust. The will provides for collection of that property, payment of Probate expenses, and transfer of whatever is left to the trust. In effect, whatever is left in the Probate estate "pours over" into the trust and is then administered according to the terms of the trust. The will can also name guardians for minor children and can address other matters that do not relate only to "assets."
