Legal analysis: the time limit for applying for court investigation and evidence collection depends on the type of evidence. Generally speaking, it should be submitted and exchanged before the court session, seven days before the expiration of the prescribed time limit or within one week before the court session. However, if new evidence appears during the trial or the parties are unable to provide evidence, they may also apply. If the application is rejected, a notice shall be served on the party concerned or his agent ad litem. If you don't understand, please consult the relevant lawyer.
