各地规矩是不同。在ｊｅｒｓｅｙ：

The cost for filing a complaint in Small Claims is:

$15 for one defendant.
$ 2 for each additional defendant.
Currently the fee is $7 for each defendant served by certified and regular mail. This is subject to change, however. [A fee for mileage may be charged instead of the $ 7 mailing fee if the complaint is served personally by a court officer. Staff of the Special Civil Part can inform you of the mileage fee, if any.] Make a check or money order payable to the Treasurer , State of New Jersey.
