Can a single mother with her daughter legally move into a man's account?

Haha, it is possible to follow the national household registration management policy, but the situation you mentioned involves the policy compensation for relocation. One place is different from another, especially in the villages of big cities. This problem is limited by ordinary villages or communities, otherwise all the residents will move here, which will have a great impact on everyone's interests. You can go to the local village Committee or community to find out the situation before making a decision.
