It is very important that your Will govern the distribution of your assets upon your death. If your Will establishes trusts for family members, only assets that pass under your Will will pass to those trusts. Likewise, if your Will includes tax planning, only assets that pass under your Will will be available for tax planning purposes. Survivorship Accounts pass outside of your Will. Therefore, your survivorship accounts should be retitled as non-survivorship accounts; otherwise, the trust, tax planning and other benefits of your Will may be impaired or even lost.
