| You will need to review the language used when the account was opened. This is sometimes located on the signature card; it is in the fine print. State law also needs to be consulted. My experience has been that a joint account is established 'as a joint tenancy with right of survivorship', which means that the survivor of an account owns all of it after the death of the joint account owner. However, this may be just a legal presumption that can be overcome with other evidence (by contract, fraud, course of business). But as far as the bank is concerned, it can deal with the survivor and let third parties fight it out in court. |
