The verdict against Marine Le Pen struck like a political bomb in France, where Le Pen has topped all opinion polls in the run-up to the election in two years.
She appealed directly to the Paris Court of Appeal, which states that three different appeals have been submitted.
The court writes in a statement that it "will evaluate the case within a timeframe that could mean a verdict can be delivered during the summer of 2026", writes Le Figaro.
Thus, if Le Pen wins her appeal, she could stand in the next presidential election.
Le Pen and around 20 other party representatives for the National Rally were convicted on Monday for having used EU funds illegally.
In addition to being banned from running in elections for the next five years, Le Pen was also sentenced to prison and heavy fines for embezzlement of EU funds.
Of the four-year prison sentence, half is conditional. If it is enforced, she is expected to serve it with an electronic tag, without being imprisoned.
In addition to Le Pen, all 23 other convicted individuals have appealed their verdicts.
French media report that the judges who convicted Le Pen have been threatened, which is being investigated by the police.
