N.J. Stat. § 56:8-156: Unsolicited check, unaccepted, immunity from liability for use.

4. No person in whose name an unsolicited check is issued shall be liable for any amount resulting from use of that check or account, unless the person who is the holder of the account upon which the check is to be drawn, or who is the payee on the check, as the case may be, has accepted the check or account by using the check or account. Failure to destroy or return an unsolicited check shall not constitute acceptance of the check or account.
