The non-relegated team from Ceuta (Group14) and Melilla (Group13) are eligible for promotion to the División de Honor if there is an opening. If either region has both teams relegated from both the División de Honor and the Liga Nacional, the relegated Division de Honor team(s) enters the Liga Nacional and the Territorial champion(s) is directly promoted to the División de Honor. If the relegated División de Honor team was directly promoted in the previous season, it shall be relegated to its Territorial league and the Territorial runner-up is promoted to the Liga Nacional. Four Andalusian teams are relegated from both groups.
