A pour over will is a will with a clause in it that instructs that all property at the time of the testator's death be poured over into a trust that has set up during the testator's lifetime. The pour-over clause is intended to make sure that any property not included in the trust that has accumulated beyond the time the trust was set up is added to the trust. Property that is added to the trust through a will must first be probated and then put in the trust. In the case of a pour over clause, the trust that it is going to pour over into does not have to have been funded during the decedent's life, it only had to have been created and in existence prior to death.
