Hunt said he and Overeem have a verbal agreement with the UFC, but insists the fight could be scrapped if the UFC fails to meet his demands.
"My clause will protect me in this instance and take the financial gain of the opponent of caught cheating," Hunt told markhunt.tv.
"That deterrent will protect me and other fighters. I'm pushing for this clause, I want to fight and I am ready. If the fight doesn't go ahead it's not my doing.
"I will not fight without this clause. I've already fought three dopers in a row and I'm not going to fight again without security. All I want is a fair go and an even playing field."
The fight has the potential to catapult both Hunt and Overeem to a title fight against heavyweight division champion American Stipe Miocic as a top ranked contender.
However, Hunt and Overeem would have to impress in the fight to jump the queue waiting for a chance to fight Miocic with Brazil's Fabricio Werdum (No. 1 contender) and American Mexican Cain Velasquez (No. 2 contender) fighting at UFC 207 on New Year's Eve.
Overeem has not fought since his title fight knockout at the hands of Miocic in September.
It will be the second time Hunt and Overeem have fought in an MMA event, but the first in the UFC.
They last crossed paths at the Dream 5 event in 2008 where Overeem submitted Hunt in the first round.
