Legal analysis: In most cases, once the demolition compensation agreement is signed, both parties need to perform it and cannot go back on their word. However, because the relationship between the fields involved in the demolition is very complicated, various situations may occur, so let's look at the following situations together and we can go back on our word; If there is no capacity or the demolition compensation agreement signed by minors, then the agreement can be considered as revocable; There are serious loopholes, irrationality or deception in the signing of the agreement, which can be revoked if the other party violates its true meaning; In the process of demolition, if there is an illegal act or the evaluation is seriously unreasonable, the demolished person may request to cancel it; If the documents related to house demolition are revoked or the other party violates the law, then the signed contract is also problematic and can be revoked; Under the above circumstances, even if the demolition compensation agreement is signed, the demolition compensation agreement can be revoked or changed through court proceedings.

Legal basis: Article 490 of the Civil Code: If the parties conclude a contract in the form of a contract, the contract is established when the parties sign, seal or print it. Before signing, sealing or fingerprinting, one party has fulfilled its main obligations, and the contract is established when the other party accepts it. A contract shall be concluded in written form as stipulated by laws, administrative regulations or agreed by the parties. If the parties do not do this in writing, but one party has fulfilled its main obligations and the other party accepts it, the contract is established.
