Connecticut General Statutes Title 36A. The Banking Law of Connecticut § 36a-290. Joint deposit and share accounts

(a) When a deposit account has been established at any bank, or a share account has been established at any Connecticut credit union or federal credit union, in the names of two or more natural persons and under such terms as to be paid to any one of them, or to the survivor or survivors of them, such account is deemed a joint account, and any part or all of the balance of such account, including any and all subsequent deposits or additions made thereto, may be paid to any of such persons during the lifetime of all of them or to the survivor or any of the survivors of such persons after the death of one or more of them. Any such payment constitutes a valid and sufficient release and discharge of such bank, Connecticut credit union or federal credit union, or its successor, as to all payments so made.

(b) The establishment of a deposit account or share account which is a joint account under subsection (a) of this section is, in the absence of fraud or undue influence or a preponderance of the evidence to the contrary, prima facie evidence of the intention of all of the named owners thereof to vest title to such account, including all subsequent deposits and additions made thereto, in such survivor or survivors, in any action or proceeding between any two or more of the depositors, respecting the ownership of such account or its proceeds.

(c) This section shall not apply to any deposit account or share account where any owner died before October 1, 1971, nor shall it apply to any action pending on that date.
