By the Court,
Wallace, C. J.:In January, 1871, the plaintiff commenced an action of assumpsit against the defendant, and in the following July obtained judgment against him for some five hundred and fifty dollars, and costs of suit. Upon filing the complaint a writ of attachment was issued, under which writ the Sheriff duly attached all moneys of the defendant in the hands of an incorporated savings and loan society in San Francisco called “La Societe Francaise d’Epargnes et de Prevoyance Mutuelle,” in which bank the defendant was a depositor. Upon the service of the writ of attachment the bank gave answer as follows: “There are six hundred dollars standing to the credit of P. Vincenot on the books of the society, for which he holds a pass boob. I do not know if said pass book has been assigned or not. On the presentation of said pass book the amount will be paid to the holder theréof.”
Upon rendition of the judgment an execution was issued, and being levied upon the moneys in the hands of the bank, an order was subsequently obtained to examine its manager before the Court Commissioner touching the moneys of the defendant on hand. Upon this examination it was disclosed that by the books of the bank it appeared that some six hundred dollars and upwards remained on hand to the credit of the defendant. It further appeared that among the bylaws of the bank were the following:
“Art. 13. A pass book with a copy of these by-laws annexed is delivered to each depositor at the price of fifty cents, payable into the Sinking Fund. In this pass book is entered to the credit of the depositor all sums deposited by him, and to his debit all sums reimbursed to him. Pass books are transferable to order.”
*328Art. 78. Every member must, by subscribing to the present by-laws, declare that he, without reserve, accepts the same in their entirety as the rule governing his rights and duties toward La Soeiete Francaise d’Épargnes et de Prevoyance Mutuelle.”
It was also stated by the manager upon his examination that he could not say whether or not the bank owed the defendant any money; that the defendant, as a depositor, held a pass book, transferable like a note drawn to order, and that it was not known whether or not the defendant had made a transfer of his pass book; that though the bank had not, in this instance, received any notice of the transfer, still, if such transfer should turn out to have been actually made, the bank would have to pay the bearer the amount shown upon the book; that there was no by-law or rule of the bank requiring notice to be given to it of the fact of transfer of a pass book. The pass book of the defendant is in the following form:
In the front of the book, and attached thereto, is the form of a printed order as follows:
*329“ Order for Money on Deposit.
“ Societe Francaise d’Epargnes et de Prevoyanee Mutuelle.
“ San Francisco, Cal.
“ Pay to-or order the sum of-dollars standing to my credit on the books of said Society, and charge the same to my account.
“ Dated the-day of-, 187—.”
An order having been subsequently entered by the Court that the bank pay over to the Sheriff such portion of the moneys in its hands standing to the credit of the defendant as would satisfy the judgment and costs, it prosecutes this appeal from the order.
First—It is claimed for the bank that its indebtedness to the defendant, as one of its depositors, shown by the pass book delivered to him, must be considered to be an indebtedness evidenced by a negotiable instrument issued by the bank, and yet outstanding, and that it results that the proceedings had under the attachment were ineffectual. It is said that the by-law which authorized the pass book to be transferred “ to order ” constituted it a negotiable instrument, and the moneys thereupon appearing to he owing must be considered as moneys owing upon an outstanding negotiable security.
But we are of opinion that this view cannot be supported. Even supposing that the by-laws in question fairly import an attempted agreement to that effect between the bank and each individual depositor, it is clear that such an agreement, if it could operate between the parties, could not defeat the rights of any one not a party to the agreement— as the plaintiff here. The character of a security, as being negotiable or - otherwise, must appear not by force of the mere stipulation of the parties that it shall be such, but *330must be implied by law as the result of the form and effect of the security itself. The pass book of the bank here is an account kept between the bank and the depositor—an account acknowledged and certified from time to time, showing the business transactions of th*e parties with each other at those periods, and carrying u2>on its face a fluctuating balance. As being such an account it is not of itself a negotiable instrument, nor could any mere agreement of the parties to it have the effect to invest it with that character in a commercial sense. In this respect the account shown in the pass book is not ■ to be distinguished from the account of a merchant or tradesman kept with his customer in the same way, nor would the agreement of the parties to such account, that the account itself might be transferred “to order,” have anymore effect upon the rights and remedies of. any third party in the one case than in the other. '
Second—But were this otherwise, we see nothing in the by-laws of the bank which imports such an agreement. Counsel claim that the pass book “ under the by-laws of the bank was made payable to order, or, in other words, negotiableWe are unable to assent to this view.
That a negotiable instrument may be transferred “to order ” is clear; but it does not follow that every instrument which may be transferred “to order” is thereby necessarily become a negotiable instrument. A collateral agreement between the.parties that an instrument of writing, not negotiable, might be transferred by the holder to order, would not alter the character of the instrument itself.
That a negotiable instrument may be transferred by indorsement is also a general rule; but that every instrument transferable in that manner is necessarily negotiable in the commercial sense is not true. Hon-negotiable instruments are transferable by assignment; but in this State such assignment maybe effected by indorsement, “in the same *331maimer as bills of exchange are.” (Hitt. Gen. Laws, Sec. 372.) The bank here and the depositors might, for their own convenience, and as between themselves, agree upon any method of transfer of deposit books—they might adopt the method usually pursued with reference to negotiable paper, or they might require the transfer to be attested and acknowledged with the formalities and solemnities requisite in a conveyance of real estate—these are mere regulations of their own business transactions inter sese ; but whatever the method authorized by their by-laws, these cannot impart the character of negotiability to a mere deposit account, or to any other writing not of itself a negotiable instrument under the general law merchant, or by the statutes of the State.
The order is affirmed.
