New Jersey Statutes Title 15A. Corporations, Nonprofit 15A § 5-18

a. Unless otherwise provided in the certificate of incorporation or bylaws, every member entitled to vote at a meeting of members or to express consent without a meeting may authorize another person or persons to act for the member by proxy. Every proxy shall be executed in writing by the member or the member's agent, except that a proxy may be given by a member or the agent by telegram or cable or its equivalent. A proxy shall not be valid for more than 11 months unless a longer time is expressly provided therein, but in no event shall a proxy be valid after 3 years from the date of execution. Unless it is coupled with an interest, a proxy shall be revocable at will. A proxy shall not be revoked by the death or incapacity of the member but the proxy shall continue in force until revoked by the personal representative or guardian of the member. The presence at any meeting of any member who has given a proxy shall not revoke the proxy unless the member shall file written notice of revocation with the secretary of the meeting prior to the voting of the proxy.

b. A person named in a proxy as the attorney or agent of a member may, if the proxy so provides, substitute another person to act in that person's place, including any other person named as an attorney or agent in the same proxy. The substitution shall not be effective until an instrument effecting it is filed with the secretary of the corporation.
