Joint Account Registrations
Joint tenants with rights of survivorship (JTWROS) passes a deceased owner's interest automatically to the survivor(s); tenants in common (TIC) passes the deceased's stated percentage to their estate instead.
Other registrations the exam touches: individual accounts (one owner; others trade only with written authorization), transfer-on-death designations that skip probate, and fiduciary accounts (trust, estate, guardian) where documents establish authority.
