立案 (lì àn): เพื่อลงทะเบียน (กับหน่วยงานอย่างเป็นทางการ)

Attorney Zhang, we have received the divorce litigation materials you submitted the day before yesterday; the court will decide within seven working days whether to register the case.

After Mr. Wang discovered that his credit card had been fraudulently used, he immediately went to the police station to report it, and the police completed the case registration procedures the same day.

Due to insufficient evidence, the procuratorate did not register this corruption case, but stated that it would re-examine it if new leads were found.

Professor Li, your research project application has passed the preliminary review. The university's research office requires you to supplement the budget details as soon as possible so that it can be officially registered.
