China's house ownership is publicized through registration, and the name on the certificate is the most effective evidence, so it is difficult to get back the house ownership.
To find a solution, consider several aspects:
1, repair, maintenance, renovation costs, please repay your uncle. The old house is not worth 50 thousand, and the decoration cost 30 thousand to 40 thousand, and most of the value can be taken back;
Who owns the rice field where your brother-in-law built his house? Whose house photo is this? You can think from this aspect.
3, the above two aspects can be used as the weight of the price negotiation of buying old houses, and slowly convince it.
