Motion for Leave to Amend Rules:
To amend a pleading where leave of court is not required, the amended pleading is simply filed with the court and served on all parties. FRCP 5(a) and (d)(amended 12/01/07). Service of process may need to be effected on parties who have not yet appeared.
To seek leave of court to amend a pleading based on stipulation, customarily the party seeking to amend prepares and obtains the signatures of the other parties on a stipulation agreeing to the amendment of the pleading, then prepares and submits an ex parte application to the Court, based on the stipulation, requesting leave to file the amended pleading.
Leave of court may be sought to amend a pleading to conform to proof at trial. FRCP 15(b)(amended 12/01/07).
