When filing or defending a forum non conveniens motion, essential evidence includes affidavits or declarations from parties, witnesses, or experts that demonstrate the convenience of the chosen forum or the inadequacy of the alternative forum. Key documents should outline the location of evidence and witnesses, with supporting details about where evidence is stored and where witnesses reside. Additionally, documentation of the alternative forum's legal adequacy, such as laws and procedural rules, is crucial, especially when defending the motion by showing the alternative forum’s limitations. Presenting relevant legal precedents that support the chosen forum or argue against dismissal strengthens the case. All evidence should be presented clearly and comprehensively, with a focus on demonstrating the fairness and practicality of the forum in question.
