The charges are being issued by the ECB rather than the International Cricket Council.
Arif will be charged with being Vincent's accomplice in allegedly rigging the match, which was televised live on Sky.
It attracted bets totalling more than £12 million ($23.65 million) on one regulated gambling website alone - the highest total for any match of its kind in the past three years - and countless more millions with illegal bookmakers in India.
There were suspicions at the time the match was corrupt but it was cleared by the ICC's anti-corruption unit following an investigation by its analysts which failed to uncover any wrongdoing.
But the case was reopened in August 2012 by the ECB's own security unit, spearheaded by former Metropolitan Police murder squad detective Chris Watts, which has found enough evidence to move to charging players.
It emerged last week that Vincent told investigators he was approached by his fixer "NG" in a hotel in Brighton the day before the match and told he would receive £40,000 ($78,800) to throw the game, which was a crucial group match for Sussex, who would have been guaranteed a place in the semifinals if they had beaten Kent.
Vincent was told by his bookmaker handler to approach a third Sussex player, but that person turned down the offer to join in the fix and was furious in the dressing room after the match because he knew it had been rigged.
There is no suggestion any other player from either team was involved in the alleged fix.
Sussex appeared to be cruising to victory in the match despite Arif's expensive bowling in the Kent innings.
He took the new ball but bowled only six overs and conceded 41 runs with two wides, an economy rate of 6.83, his second-worst figures of the season in 40-over cricket.
In reply, Sussex looked set for a win at 76 for no wicket, chasing a target of 217. But they lost four wickets for seven runs in four overs including that of Vincent who, batting at three, was run out for one off six balls.
Arif batted at nine and scored 11 off 29 balls as Sussex were bowled out for 202 to lose by 14 runs.
Arif was dropped for the next match against Middlesex and played only three more one day matches for Sussex before losing his contract.
Vincent is in Auckland, and it was unclear late last night whether he will fly back to England to face punishment, given he has already admitted his involvement in fixing, which includes approaching Lancashire team-mate Mal Loye and others.
It is embarrassing for the under-fire ICC anti-corruption unit that its own officers gave a clean bill of health to a match which is now going to be the subject of a high-profile fixing case.
The 32 year-old Arif was born in Pakistan and qualified as a non-overseas player for Sussex through his wife's Danish passport. He spent two seasons at Hove and was allegedly willing to fix a match while he was still trying to establish himself in the first team; the game against Kent was his 17th in his first year on the staff.
His lawyers did not respond when the Daily Telegraph contacted them for comment.
Arif was served with his charge papers by the ECB at the end of April and is now suspended from all forms of cricket. He was released by Sussex in 2012 and has since played a handful of professional Twenty20 matches in Pakistan and played for two seasons, including an appearance in April this year, for Little Stoke Cricket Club in the North Staffordshire and Cheshire Premier division.
He is currently thought to be living in the north of England. If the charges against the players are proven, bans issued in England by the ECB would apply all over the world because of an agreement between cricket-playing countries.
Although three Pakistan internationals and one English county player have over the past two-and-a-half years been sent to prison for spot-fixing - when one small part of a match is rigged, rather than the whole outcome - it is thought unlikely Vincent and Arif will face criminal charges because of a view that such prosecutions are not the best use of taxpayers' money.
