The Grade II listed Italianate building fell into disrepair, until its present owners bought it in 1998.
They've since restored it - and the next-door police house - into an elegant four-bedroom home
It's now on the market for £650,000 with agent Fine & Country.
The most striking feature of the house is the enormous double-height reception room. This still contains the original witness boxes and journalist box, moved from their original location to create a balcony currently used as a study.
"It has drop-down desk tops within it which have been written on by numerous EDP and Lynn journalists over the years," say the owners.
"You can just imagine the boredom of someone who inscribed 'I was not born here, but I may die here' or 'Limbo must be like this'."
Other original features include panelling, cornices and ceiling roses.
The house is entered via a dramatic octagonal hall, with a circular glazed cupola above. It still holds the benches used by people waiting to go into court.
There's a cosy sitting room and four bedrooms - two ensuite - as well as a family bathroom and ground floor shower room and a large kitchen with a range cooker.
Outside, the gardens are a particular feature, with a formal Italianate design, three small courtyards and parking for five cars.
"Looking back now it is easy to forget how much work was done," say the owners. "Converting and living in the Courthouse has been an adventure and it has certainly provided us with lots of wonderful memories."

This mansion fits the bill largely because it's relatively northern, and there’s a good quantity of imposing stone around.
However, far from the miserable conditions in the shadow of the wall, this is actually a lovely 13-bedroom estate in South West Scotland.
Penninghame is for sale for offers over £2,620,000, and for your money you get a beautifully renovated, grand home, with immaculate grounds.
In Game of Thrones, this isn’t the most hospitable place for a visit, and there's always the risk of being sent to your death through the ‘moon door’. In reality, this spectacular Somerset property has been selected for the incredible height of the tower.
This property in Shepton Mallet is up for auction, with a guide price of £850,000. The current owners run the former 19th century folly as an attraction for schools and walkers - with a tea room and gift shop attached to the tower.
The property also comes with separate living accommodation, with three bedrooms and an original flagstone floor. There are two log cabins in the grounds to provide another income stream.
In the books, the Greyjoys occupy the forbidding Iron Island. This version offers scenery that's every bit as spectacular - with a comfortable home and a thriving tourist business thrown in for good measure.
The Isle of Tanera Mor in Ros-shire (off the coast of North West Scotland) is on sale for offers over £1,950,000. It's the main island of the Summer Isles archipelago.
As well as the main house, you get a tourist business, including a number of holiday cottages. The owners also operate their own independent postal service by boat, and produce their own stamps - which are sought after by collectors.
The home of the Lannisters is one of the most opulent in Game of Thrones, and the property picked out to emulate it is certainly very grand.
It’s actually a hotel in Dornich, in a converted 15th century castle. It boasts 25 bedrooms and bathrooms, a restaurant and bar, and there’s planning consent in place to expand with more bedrooms and a spa.
Some of the rooms have been decorated to feel light and modern, while others come with bare stone walls and at the moment feature heavy wooden four-poster beds that are fit for a Lannister. The place is also licenced as a wedding venue, but its probably best not to mention weddings.
There are around 312 acres of grounds - including a spectacular formal garden, as well as a tennis court and swimming pool. The main property incorporates part of a 16th century mansion, with early 17th century additions and a 19th century wing.
Everything about this property is impressive, from the enormous modern kitchen to the spectacular entrance hall with more than enough room for a grand piano.
In addition to the main building, there are two cottages, a flat, a range of farm buildings and outbuildings - with woodland, arable land and pasture. It's hardly surprising that it’s on the market for £8,950,000.
Storm’s End, the seat of the Baratheons in the books, isn’t the balmiest of places. This home in Anglesey should be a far more pleasant place to live - and was chosen for its impressive fortifications, its position on the headland, and its stunning views - rather than its climate.
The 9-bedroom home is on the market for £1,3750,000, and comes with two separate holiday properties, 17 acres around the headland, and freehold of the working lighthouse.
This land is known for its golden glow and narrow winding streets, in a land free from the rule of the Iron Throne.
The property picked to emulate its style is a pretty three-storey townhouse in Ludlow. For £249,950 you get three bedrooms in the middle of town with great period features and a lovely view over the town.
