Do criminal lawyers lie?

You seem to mean that the plaintiff sued the defendant for money, but the plaintiff also owed the defendant money, that is, the original defendant owed money to each other. If the plaintiff cannot repay the debt, the defendant has the right of set-off.

The lawsuit is mainly based on evidence, and the principle of "whoever advocates it will give evidence" is implemented. The proposer does not produce evidence to prove that his claim is generally not supported by the court unless the other party admits it. If the proposer can't prove it, he will bear the consequences of failing to prove it. Civil cases are different from criminal cases, and the rights and obligations of the original defendant are equal. Plaintiffs and defendants generally bear the burden of proof for their claims. For the other party, whether to admit his claim depends on my attitude.
