You or someone else may start your case by filling out a court form. You may file by mail if you have a small claims case in Nassau County and Western Suffolk County or if you live outside New York City and you want to sue a party within New York City. The form describes your claim to the Court.
Bringing a motion by notice usually gives the other side weeks to respond and sets no real deadline for the court to make a decision. If the movant cannot wait weeks, she may submit an order to show cause, asking the court to set tight deadlines for a response and to make a decision.
An Order to Show Cause is way to present to a judge the reasons why the court should order relief to a party. For example, a party can seek an order granting discovery, or dismissing all or part of an action by bringing an Order to Show Cause.
In California, parents have the right to petition for an emergency custody hearing in family court under certain circumstances to protect their child from imminent harm.
In New York, this type of substitute motion is called an "Order to Show Cause." An order to show cause can be heard anytime the court directs, even fewer than the usual eight days, and even as short as a few hours later, if the court is convinced there's a real emergency.
