It costs almost 8000 yuan to install water and electricity for a hotel, almost half a year. What if that person still doesn't pay back the money?

Excuse me, do you have any written evidence of this between you? This document is very important and is the only strong evidence that you can get your money back. If it's just your's verbal agreement, it will be very troublesome. If the other party does not admit that you have this agreement, it will be difficult for you to get your money back. If you have a written agreement with him, you can directly ask their unit for money. If the other party does not give money, you can choose to call the police, call the police for fraud, or directly sue the court. As long as you have the certificate in your hand, the lawsuit will win, and the legal fees will be paid by the other party!
