(5) Where the manner of service for actions or proceedings in this
court includes mailing the summons to the person to be served at his
last known residence, if the person to be served is a corporation and if
either: (i) an officer of such corporation, (ii) the managing agent of
such corporation for the premises involved in the suit or (iii) a person
designated by such corporation to receive notices in its behalf, other
than the secretary of state, has been named a party to the suit, the
summons may, as an alternative, be mailed to the registered address of
such corporation or, if such corporation has not registered as required
by such code, to the address of such corporation set forth in a document
filed or recorded with a governmental agency.
(6) A copy of the summons with proof of service shall be filed in the
manner provided in section four hundred nine, except that such filing
shall be made with the clerk of the housing part in the county in which
the action is brought.
(n) Nothing contained in the section one hundred ten shall in any way
affect the right of any party to trial by jury as heretofore provided by
law.

part to assist persons without counsel. Such assistance shall include,
but need not be limited to providing information concerning court
procedure, helping to file court papers, and, where appropriate,
advising persons to seek administrative relief.
