I used to think due diligence on a water well meant pulling a driller's log and calling it done. I was wrong, and it cost me real money to learn otherwise.
Before I bought my current place, I didn't ask whether the seller had ever leased subsurface water rights to a third party. Turns out, a municipal water authority had a pumping agreement tied to the land — not the person — that survived the sale entirely intact. Nothing in the deed flagged it. Nothing in the title search surfaced it. I found out when a meter reader showed up six weeks after closing.
In Texas, groundwater ownership is governed by the rule of capture, but leases and contracts attached to that water can run with the land just like any other encumbrance. Most buyers have no idea to even ask the question.
Now I request a full written disclosure of any water lease, pumping agreement, or district commitment before I'll make an offer on anything with a well.
Has anyone else in prior appropriation states found water contracts hiding in places the title search completely missed?
