Kimberly Wilde, 49, pleaded guilty on Monday to one count of wire fraud during an appearance in U.S. District Court in Rutland.
When Wilde is sentenced, the court also is expected to order full restitution for "all out-of-pocket" losses, Assistant U.S. Attorney Gregory Waples said.
"That figure will be determined by the court at sentencing," Waples said. "Wilde has already paid some money back to the firm, so that repaid amount will be excluded from the restitution order."
Wilde had managed finances for Potter Stewart Jr. Law Offices on Main Street. In that capacity, she had access to financial information including the firm's checks, bank statements and credit cards.
Between January 2007 and January 2013, authorities say, Wilde embezzled money from the firm by using company checks, electronic transfers and the firm's credit cards to benefit herself.
Wilde altered bank statements and other records to conceal the thefts, officials said.
The law firm discovered the embezzlement and reported it to authorities, Waples said. Last month, Wilde waived indictment and agreed to the guilty plea that was formally entered on Monday.
Wilde's sentencing date was not set during Monday's court proceeding. Waples said sentencing may happen in November.
