Yes. The Acquisition Sub-DAO Committee hires local lawyers and land surveyors to run due diligence and also register each land it acquires. Lands are all owed by the LandDAO legal entity
This is a very good approach from LandDAO it will help them to escape getting involved with lands that are on dispute because the local lawyers will be from the communities where they have the lands and involving them in the committee will help to get all the necessary things done and document for reference purposes. So far the lands are all owned by LandDAO legal entity there is nothing else to worry about when investors want to invest.
From scanty experience base on random discussions I had to enter with a lawyer friend who practically work with some local real estate companies in my locale, he at times talks about how they get into a land dispute about a land that they made proper checking and due diligence as you called it before getting their company to purchase for a resell purpose. So what am I saying in essence, land disputes challenges can not completely be eliminated in real estate line of business. It's just about how the company in question is able to handle it when it happens, that's what does matters.
