The debtor transferred assets before I got the order — can I reverse it?

Possibly. If the transfer was made to defeat creditors (a fraudulent conveyance — habrakat nose'im ), Israeli courts can set it aside. You need to show that the transfer was made with intent to defraud creditors and that the recipient knew of this intent (or received the assets as a gift). Act quickly — gather evidence of the transfers and consult an attorney immediately.
