Old house reconstruction, is the old real estate license valid?

If the house is collective property, it must be approved before it can be renovated, otherwise it will be treated as illegal building. In this way, if there is a property right dispute, illegal buildings will generally not be accepted. If there is approval, it is still the name of the original property owner. Generally speaking, it is still the property owner. However, if there is a family agreement, it can be recognized as family property, and its share distribution shall be handled according to the agreement.
