Mineral Rights and Trustee Sales

[Adam R.]

Question -

When you purchase a property at trustee sale do the mineral rights also convey?

My Guess -

Take a state like Texas for example. When you purchase a home in Texas if the mineral rights do not convey there is a specific exclusion that must be made as an addendum to the purchase agreement. So my guess would be that if a property went to foreclosure and you purchased it at trustee sale, then by default you would get the mineral rights unless the previous owner somehow got the mineral rights added to the deed?

Just a guess by me and probably incorrect. Wondering if anyone knows.
