N.J. Stat. § 17:9A-88
Shares of the capital stock of a bank held jointly or as tenants in common by two or more persons may be represented and voted in person or by proxy at any meeting of the stockholders by any one of such persons, unless another joint tenant or tenant in common seeks to represent or vote any of such shares in person or by proxy. In the latter event, the written agreement, if any, which governs the manner in which such shares shall be represented or voted, shall control if presented at the meeting. If there be no such agreement presented at the meeting, the majority in number of such joint tenants or tenants in common present in person or by proxy shall control the manner of representation and voting. If there be no such majority, or if there be two such joint tenants or tenants in common, both of whom seek to represent and vote such shares, the shares shall, for the purposes of representation and voting, be divided equally among such joint tenants or tenants in common present in person or by proxy.
