The late Saudi Foreign Minister Saud Al Faisal, son of former Saudi King Faisal, hired a production company that is suing Royal family over unpaid £80,000 bill.
The Saudi Royal Family is being sued for cash used to make 'personalized porn films' for one of its most distinguished princes.
They are said to have been produced in Paris for the late Prince Saud Al-Faisal who, as well as being the world's longest ever serving foreign minister, is said to have bought 'made-to-order' erotica starring his mistress.
The lawsuit claims Prince Saud regularly used to send instructions about what he wanted to see in the films to the Atyla concierge company in the French capital.
The films were reportedly shot in Prince Saud's luxury family apartment close to the Arc de Triomphe, as well as in hotel rooms.
Atyla says the bills were never paid by Prince Saud, who died in 2015, aged 75, and the company has launched proceedings in Nanterre, the Paris suburb.
Court papers show that the company wants the equivalent of £78,000 in 'unpaid invoices' that should have been settled by a company managing property owned by Prince Saud.
While the sum is itself small in relation to the Royal Family's colossal fortune, payment will effectively prove that the Paris flat was used as a base to make the X-rated movies.
It is now officially part-owned by Prince Saud's surviving children, who dispute that their father would be involved in such seedy activity, and refuse to pay the alleged debt.
According to court evidence, the otherwise unidentified Moroccan mistress is said to have been left a Paris flat and cash in Prince Saud's will.
Lawyers for the management company of the Avenue Bugeaud property meanwhile insist that 'no services were ordered' from Atyla, least of all pornographic film shoots.
The case, which will be heard in September unless there is an out-of-court settlement, comes after France issued an international arrest warrant for Saudi Princess Hessa Bin Salman following claims that she ordered a bodyguard to' beat up and kill' a painter and decorator in Paris.
Princess Hsesa, 43, pleaded diplomatic immunity against prosecution and then fled the city in 2016 after allegedly telling her armed employee: «You have to kill this dog, he doesn't deserve to live».
The Princess's brother, Crown Prince Mohammed Bin Salman, is currently on a three-day visit to France, where he is being hosted by President Emmanuel Macron.
Last month, the Prince also visited London, where he was a guest of the Queen and Prime Minister Theresa May.
Saud Al Faisal, a Princeton University graduate who spoke seven languages, served as Saudi Arabia's foreign minister from 1975 until 2015 — a world record.
He was married to his cousin Al Jawhara bint Abdullah bin Abdul-Rahman and had three sons and three daughters while becoming a hugely influential figure on the world stage.
The Saudi Arabian embassy in Paris has refused to comment on either of the ongoing legal cases.
