The most frequent errors include relying on vague or outdated assumptions about the defendant's principal place of business, misinterpreting the scope of long-arm statutes by overlooking recent jurisdictional caselaw, failing to investigate whether digital transactions or advertising specifically targeted the forum state, and neglecting to confirm contractual forum selection clauses. These can be proactively avoided by implementing a pre-filing checklist that mandates verifying the defendant's current corporate registration and physical operations, conducting a thorough "minimum contacts" analysis rooted in recent appellate decisions, preserving all digital evidence (like geotargeted ads or user data), and systematically reviewing all contractual documents for binding venue provisions before submission.
