Written notice of the date, time and place of the hearing, shall be provided to all parties in accordance with local court rules.
    (2)(a) On whom made. If a party is represented by an attorney of record, service shall be made upon the attorney. Otherwise service shall be made upon the party.
    (b) Method. Papers shall be served as follows:
        (1) by delivering them to the attorney or party
    
personally;
        (2) by leaving them in the office of the attorney
    
with the attorney's clerk, or with a person in charge of the office; or if a party is not represented by counsel, by leaving them at the party's residence with a family member of the age of 10 years or upwards;

            (i) A party or attorney electing to serve
        
pleading by facsimile must include on the certificate of service transmitted the telephone number of the sender's facsimile transmitting device. Use of service by facsimile shall be deemed consent by that party or attorney to receive service by facsimile transmission. Any party may rescind consent of service by facsimile transmission in a case by filing with the court and serving a notice on all parties or their attorneys who have filed appearances that facsimile service will not be accepted. A party or attorney who has rescinded consent to service by facsimile transmission in a case may not serve another party or attorney by facsimile transmission in that case.

In cases in which there are 2 or more minor-respondents who appear by different attorneys, service on all papers shall be made on the attorney for each of the parties. If one attorney appears for several parties, the attorney is entitled to only one copy of any paper served upon the attorney by the opposite side. When more than one attorney appears for a party, service of a copy upon one of them is sufficient.
    (3)(a) Filing. When service of a paper is required, proof of service shall be filed with the clerk.
    (b) Manner of Proof. Service is proved:

certificate of the attorney, or affidavit of a person, other than an attorney, who made delivery;
        (iii) in case of service by mail, by certificate of
    
the attorney, or affidavit of a person other than the attorney, who deposited the paper in the mail, stating the time and place of mailing, the complete address which appeared on the envelope, and the fact that proper postage was pre-paid; or
        (iv) in case of service by facsimile transmission, by
