The execution of the court is carried out in accordance with the legal provisions and effective legal documents, which is mandatory. If the person subjected to execution does not sign, it will not be executed. Law or law? What do you mean the plaintiff doesn't sign? The plaintiff won the case and is not going to apply for enforcement? Or did the plaintiff lose the case and refuse to enforce it? If it is the latter, it should be possible. If the former does not apply for enforcement, the court will not enforce it, nor will it auction the property of the person subjected to execution.
