My family has a piece of land that the government wants to expropriate as the basis for the relocation of immigrants, but this land used to be public.

The compensation standard for land requisition shall be compensated according to the relevant national regulations and local compensation standards!

If the village collective acquiesced in the land use right of the parties, there is nothing to say here. But if the village collective wants to deny and argue, things will be more complicated. According to the relevant laws and regulations, collectively owned land should be recovered by the parties concerned, otherwise, the village collective has the right to recover it. However, at the time of recovery, compensation should be given to the human, material and financial resources invested by the parties in reclamation.

The above is only a superficial analysis. Specific to the incident, there may be other special circumstances, which are quite different from the analysis. Please refer to the specific situation and results!
