Property Ownership Dispute: Responding to the Lawsuit and Preparing for the Preliminary Hearing

I’m a co-owner of a piece of land where another co-owner decided to build a house. Now he’s claiming adverse possession to grab full ownership, so he sued me to quiet the title. I just got served—I have 30 days to file my answer, and there’s a preliminary hearing scheduled for a few months down the road.

First thing: when I file this response, do I need to lay out every single fact and piece of evidence right now? Or can I just submit a basic response to avoid a default judgment, knowing I’ll have the chance to present my case and evidence during the preliminary hearing? I’d rather have more time to get organized.

I'm assuming I can still submit new facts and evidence via formal motions in the interim, between filing the initial response and the actual hearing.

Evidence can be brought forward and facts laid out right up until the conclusion of the previous proceeding, during the pretrial hearing, or even tucked into motions filed between the initial answer to the complaint and that pretrial stage.
