At least two mortgage payments had been paid from the fund, which was set up to help find the couple's daughter and support the family.
But the McCanns decided not to use the money for personal payments after they were made suspects by Portuguese police.
Clarence Mitchell said: "The fund has always had the ability to assist the family financially if necessary, and they've only used it to pay for two mortgage payments earlier this year.
"When they were made arguido, it stopped, which was a mutual decision on the part of the fund and the McCanns - they were happy to accept that their changed status meant they were no longer entitled to that assistance."
The Find Madeleine Fund has attracted more than £1m in public donations to help find Madeleine McCann.
The use of donations had previously been called into question after it was revealed about a third of the money had been used to meet the McCanns' living costs, publicity fees and to pay staff.
But the family defended the fund, saying they would not use it for their legal fees.
Mr Mitchell, recently appointed as the family's PR spokesman, said he would not be paid from the Find Madeleine Fund but from "private financial backers" to the McCanns.
While Kate McCann is unlikely to return to her job as a part-time GP, Gerry McCann will return to his work as a consultant, a move likely to help ease the financial pressure
