The order issued Thursday freezes a bank account with more than $115,000 in it, and bars the sale of Greig's Quincy home and a South Boston home she has an interest in.
Prosecutors asked that the assets be frozen to pay fines she may be assessed after pleading guilty last week.
The U.S. Attorney's Office says Greig's twin sister emptied $134,545 from Greig's bank account in December, six months after the fugitives were captured, and transferred the money to another bank. Prosecutors say only $115,500 remains.
