The IOUs are overdue, and they have been asked in the middle, but they are not given. Not protected by law?

The IOU is overdue and has been asking for money. As long as there is evidence of dunning, there is still a statute of limitations and it is protected by law.

Before the expiration of the IOU, if there is evidence (including telephone recordings, QQ chat records, short messages and letters, dunning letters, etc.) that the creditor has claimed the rights and interests within the limitation of action, it is equivalent to the interruption of the limitation of action, and the limitation of action can be recalculated. As long as there is evidence of dunning every two years, the debt will always have a statute of limitations and the lawsuit will be won.

Article 135 of the General Principles of the Civil Law stipulates that the limitation of action for requesting protection of civil rights from the people's court shall be two years, unless otherwise stipulated by law.

Article 140 of the General Principles of the Civil Law states that the limitation of action is interrupted by bringing a lawsuit, a party making a request or agreeing to perform an obligation. From the time of interruption, the limitation period of action shall be recalculated.
