Legal analysis: to recover the arrears, you only need to prepare a complaint and go to court to sue. At present, laws and regulations do not clearly stipulate that lawyers must be hired. You can sue yourself. If it is really difficult to write a complaint, you can file an oral lawsuit. The people's court will record the oral statement of the plaintiff and inform the other party. If it is a case that falls within the scope of legal aid prescribed by law, you can also apply for legal aid.
Legal basis: Article 120 of the Civil Procedure Law of People's Republic of China (PRC) shall be submitted to the people's court with copies according to the number of defendants. If it is really difficult to write a complaint, it can be made orally, which will be recorded by the people's court and the other party will be informed.
