The villagers' group signed a contract, totaling 12 1. How many people sign the contract to be valid?

6 1 person or more. Under normal circumstances, a villagers' group needs at least half of the people to sign a contract before it can take effect. Specifically, if the villagers' group has 12 1 person, it needs at least 6 1 person's signature to take effect. This is because, according to the provisions of the Organic Law of Villagers' Committees of the People's Republic of China, villagers' groups are grass-roots self-governing organizations with households as the unit, and their decisions need to be discussed and approved by the heads of households' meeting or the heads of households' congress. According to the law, the resolution of the villagers' group shall be adopted by more than half of the members before it takes effect. Therefore, among 12 1 members, at least 6 1 members need to sign the agreement before the contract can take effect.
