The firm operated the Lord Crewe Arms Hotel in Blanchard and the Warkworth House Hotel near Alnwick.
It also used to run the Brackenrigg Inn in the Lake District but this was sold before the administrators were appointed.
The Lord Crewe Arms was formerly part of the Abbey of Blanchard and is regarded as one of the oldest hostelries in the country with the building dating back more than 800 years.
And The Warkworth House Hotel – which is overlooked by Warkworth Castle - was once a coaching inn. Andrew Haslam and Gilliam Sayburn, based in Begbies’ offices in Newcastle, have been appointed to deal with the process.
Future to be secured
Haslam explained he is hopeful an agreement can soon be struck to secure the futures of the hotels.
He said: "Both hotels will continue to operate as normal with all forward bookings fulfilled in the usual manner whilst the hotels are fully marketed by instructed agents Christie & Co.
"We have already received several notices of interest in both historic venues and are hopeful that a successful outcome for all parties can be achieved."
J&G Inns – which was founded in 1996 – became a limited company in 2003 before acquiring the Warkworth House Hotel in December 2004. It bought The Lord Crewe Arms Hotel last year.
