Pursuant to CPLR 503(a), "[e]xcept where otherwise prescribed by law, the place of trial shall be in the county in which one of the parties resided when it was commenced; [or] the county in which a substantial part of the events or omissions giving rise to the claim occurred." CPLR 510(3) provides that, upon motion, the court may change the venue of an action where "the convenience of material witnesses and the ends of justice will be promoted by the change." A party moving to change venue pursuant to CPLR 510(3) must provide information about the prospective witnesses, including, but not limited to, their names and addresses, disclose the facts about which the proposed witnesses will testify at the trial, represent that the prospective witnesses are willing to testify, and state that the witnesses would be inconvenienced if the venue is not changed. The situs of a plaintiff's injury may provide a basis for a discretionary change of venue in that, things being equal, a transitory action should be tried in the county where the cause of action arose.
