A bankruptcy judge on Tuesday ordered former Houston hand surgeon Michael Brown and his attorneys to prepare a budget for his living expenses after his release from prison.

Brown will surrender to U.S. Marshals on Friday to begin serving a 30-day prison sentence in Florida after pleading guilty to interfering with a flight attendant.

Brown is currently living in a multi-million-dollar home in Florida that he purchased with a $4 million down payment.

U.S. Bankruptcy Judge Jeff Bohm ticked off several questionable expenses already filed by Brown's legal team, including several hundred dollars in monthly bills for gardening and pool cleaning at the home.

"He's not going to be able to keep the same lifestyle that he's been living — at least for now," Bohm said.

However, Bohm said some of those expenses might pass muster because the house may ultimately be sold to pay off Brown's long list of creditors.

Before the hearing late Tuesday afternoon, Brown, the creditors and Chapter 11 trustee Ronald Sommers met inside a cramped office space inside the federal courthouse.

Among the tangible assets that were examined in the meeting was a ranch that Brown owns. It appears to be a 122-acre parcel in Leon County. The county's appraisal district records list Michael Glyn Brown Trustee as both the existing owner and previous owner.

Sommers said there is interest in the property.

"We've got a cash buyer," Sommers said.

Bohm also ordered them to have another meeting in early December to continue the discussion about the former hand surgeon's assets.

After the court hearing, Brown and his lawyer quickly left the downtown Houston federal courthouse to catch a late flight back to Miami. An attorney representing the Chapter 11 trustee declined to comment about the case.
