ABSTRACT
A writ may be amended in any way once without leave before it is served.2 After service, provided it has not already been amended, a writ may be amended once without leave at any time before close of pleadings,3 but not so as to (a) add, omit or substitute a party to the action, (b) alter the capacity in which a party sues or is sued, or (c) add or substitute a new cause of action. Any such amendment may be made without leave only before service of the writ.
