§ 150 Medical liability actions - Summons.

If you file a medical malpractice lawsuit in Oklahoma, you have 180 days to have the summons delivered to the person or people you're suing. This is how the defendant officially finds out about the case against them.

If you miss this deadline, the case gets thrown out automatically. The good news is that "without prejudice" means you're not completely out of luck. You can usually file the lawsuit again, as long as you're still within any other time limits that apply to your situation.

The main takeaway here is simple: don't wait too long after filing to get the other side served. Work with your attorney to make sure the paperwork gets delivered well before the 180-day mark, so you don't lose your progress on the case.
