A will designed to work together with a revocable living trust (or a joint revocable trust) to ensure that all property remaining in your name at your death will be transferred to your revocable living trust (or your joint revocable trust) when you pass away. A pour-over will also appoints an executor to oversee the administration of your estate and names guardians for your minor children. Each state provides specific rules for how a last will and testament must be signed, which typically includes signing before witnesses and a notary public.
