Is it illegal to pretend to be a lawyer and ask when to pay back the money?

It is illegal to impersonate a lawyer.

If the loan cannot be repaid in time according to the agreement, and the financial institution or creditor pursues the debt through litigation, the people's court may also enforce it. As for pretending to be a lawyer, you can of course complain to the public security organs.

Whoever impersonates a lawyer to engage in legal services shall be ordered by the public security organ to stop his illegal practice, his illegal income shall be confiscated, and he may also be fined not more than 5,000 yuan and detained for not more than 15 days. Impersonation does not constitute a crime, but it may be warned by the judicial bureau or the public security. Debt collection methods are illegal, such as brushing threatening slogans, smashing and looting, which are illegal and will be subject to administrative punishment or even criminal punishment.

Legal basis: Article 15 of the Judges Law of People's Republic of China (PRC), the people's court may openly select judges from lawyers, law teachers and researchers engaged in the legal profession according to the needs of judicial work.

In addition to being qualified as a judge, lawyers who participate in public selection should also have at least five years of practical experience, rich experience and good reputation. Law teachers and researchers who participate in the open selection should have intermediate titles or above, have been engaged in teaching and research for more than five years, and have outstanding research ability and corresponding research results.
