§ 403. Summons; method and place of service.

Service of summons shall be made in the manner prescribed in supreme
court practice, including the optional method of service by mail
authorized by CPLR 312-a, but it shall be made only within the county;
provided, however, that where the cause of action arises from the
failure to make payment on goods and/or services to a person who is
lawfully engaged in the business of providing such goods and/or
services, and at the time such goods and/or services were received by
the alleged debtor, such parties named in the summons were residents of
the same county, the alleged debtor named therein as a defendant may
also be served in any adjoining county.
