Le Pen received a shortened period of ineligibility of 15 months, with the remaining 30 months suspended, alongside a €100,000 (£85,000) fine.
Jordan Bardella, 30, the current party president handling day-to-day operations, remains on standby as a potential replacement candidate if Le Pen cannot run.
Le Pen previously stated that she would support Bardella, her protege, with energy, confidence, and conviction if the situation required it.
Recent polls suggest that Bardella, who heads the Patriots for Europe grouping, could make the final-round runoff, with some polls showing his support exceeding Le Pen's.
If Le Pen does not stand, next year’s election would be the first presidential vote in nearly 30 years without a member of the Le Pen family running.
Le Pen aimed to run for president for a fourth time next spring following the conclusion of Emmanuel Macron’s two terms in office.
She was twice beaten by Macron in the final run-off, in 2017 and in 2022, when she increased her score to more than 41%.

Le Pen faced a five-year immediate voting ban last March after being found guilty during a first trial regarding the extensive European Parliament fake jobs scam.
She appealed last year's verdict, leading to a fresh trial at Paris’s court of appeal this year to fight for her political future.
She argued to the court that no systematic misuse of European Parliament funds existed and stated they did not feel they committed any crime.
