Some accounts that are registered in two or more names are not survivorship accounts. They are "co-tenant" "tenants in common" or "convenience" accounts. They do not have a survivorship feature, so they do not become the property of the survivor. Instead, when one owner dies, his or her interest in the account passes under his or her Will. Since the account holder's Will controls his or her interest in non-survivorship joint accounts, these accounts avoid the problems caused by survivorship accounts. In fact, many people add one or more family members as signers on accounts so that the accounts can be accessed in the event of the owner's disability. These accounts, if properly styled as convenience accounts, do not give rise to the problems associated with survivorship accounts.
