Chapter 7 trustee moved the court for a change of venue based on the interests of justice and the convenience of the parties. The court held that the party seeking to change venue bears the burden of establishing grounds for such change by a preponderance of the evidence. The court further held that a debtor's choice of forum, though a factor to consider, does not control the decision, and that economic and efficient administrative of the estate is the most important factor. Given that these debtors' only potential asset, the majority of their creditors, and their major business ventures were all located in Oregon, the court granted trustee's motion and transferred debtors' cases to that forum.
