Settlor
  
You create a trust for your favorite charitable cause: the neutering and spaying of domesticated skunks and chipmunks. You're passionate about it. You're going to donate your fortune to a not-for-profit dedicated to promoting education of this vital issue.
When you donate assets to the trust, you act as settlor. It’s the legal name given to the party handing over assets to the trust, though it can also be known by a number of other possible titles, such as donor or grantor.
Once handed over, the assets are run by the trustee.
