DNCG rulings
On 5 June 2012, following a preliminary review of each club's administrative and financial accounts in the Championnat de France amateur, the DNCG ruled that Pacy Vallée-d'Eure and Besançon would be excluded from participating in the CFA and would be relegated to the Division d'Honneur. Besançon later declared bankruptcy. The organization also confirmed its refusal to allow Montceau Bourgogne and Roye-Noyon promotion to the fourth division. All rulings were subject to appeal. On 26 June, the DNCG ruled that Agde would be relegated to the fifth division due to financial irregularities. A month later, Sénart-Moissy was excluded from participation in the CFA.

On 5 July, appeals for both Montceau Bourgogne and Roye-Noyon were heard. After deliberation, the DNCG ruled in favor of allowing each club promotion to the CFA. After failing in a similar appeal, Agde announced that it would appeal to the CNOSF, the National Sporting Committee of France, in order to remain in the CFA. Sénart-Moissy's appeal was also rejected by the DNCG resulting in the club falling to the fifth division.
