Do I need to change my bank and investment accounts for the revocable trust?
You should retitle your accounts so that they are in the name of the revocable trust and in such a way that the trustee signs to confirm all transactions. Much of the advantage of a revocable trust is that it affords ease of administration, both during incapacity and upon death. Assets that are not titled in the revocable trust will not receive these benefits. However, you should also have a pour over will for just this reason. If your trust contains all of the instructions for distribution, the pour over will can move the assets into the trust for distribution after death.
