ยง 6203. Attaching creditor's rights in personal property. Where a
plaintiff has delivered an order of attachment to a sheriff, the
plaintiff's rights in a debt owed to the defendant or in an interest of
the defendant in personal property against which debt or property a
judgment may be enforced, are superior to the extent of the amount of
the attachment to the rights of any transferee of the debt or property,
except:

1. a transferee who acquired the debt or property before it was levied
upon for fair consideration or without knowledge of the order of
attachment; or

2. a transferee who acquired the debt or property for fair
consideration after it was levied upon without knowledge of the levy
while it was not in the possession of the sheriff.
