I owe you 1 100 yuan. Is it true that he asked me to prepare for the lawsuit?

If there is a lawsuit, the court will inform you that they have no authority to do anything instead of the court. Having a loan of 1000 yuan, to be honest, even the standard of prosecution is not enough, and the probability of online loan being sued will be very small, so you should pay more attention to making money and paying back the money at present.

The information you received is estimated to be that the creditor entrusts a debt collection company to collect debts on its behalf, and the short message means to sue if the money is not returned. Creditors have the right to bring a lawsuit to the court, and the court will serve a summons to open the court.
