A written agreement fixing the place of trial, made before an action is commenced, shall be enforced upon a motion for change of venue, pursuant to CPLR 501 and 511 A contractual forum selection clause is prima facie valid and enforceable unless it is shown by the challenging party to be unreasonable, unjust, in contravention of public policy, invalid due to fraud or overreaching, or it is shown that a trial in the selected forum would be so difficult that the challenging party would, for all practical purposes, be deprived of its day in court.
