Our land contract here is 30 years. Is it illegal for the village committee to organize villagers in our village to sign a 50-year lease contract?

1. Leased land is a form of land transfer, but the term shall not exceed the remaining term of the original contract, and the excess shall be invalid.

2. If the lessee uses the land for construction and changes the original agricultural use of the land, the whole lease contract is invalid. If the lease contract is invalid, you can demand the return of the land.
