In Deed

County clerks in Texas won't record your deed unless either

A) It is signed by grantor and notorized
B) It is signed by grantor + two witnesses

Compare to self-proving will:

It is signed by testator and two witnesses and notarized
if its not notarized, the witnesses have to come testify.

Compare to Order for muniment of title:

Order for Muniment of title is an order from a judge, it goes from the court clerk to the the county clerk. Ba-dang!

Compare to affadavit of heirship:

Also serves as a Muniment of title, but is rebuttable within 5 years of recording. Magically, it becomes irrebutable after 5 years.

Compare to Mechanics lien:

Perfected on receipt if all formalities of recording the affadavit of the Mechanic's lien statute are met. Primes the mortgage lien!

BTW: The maximum deficiency judgment after a lien is foreclosed, in Texas, is limited to the difference between FMV and debt; obviously its less if the deficiency is less, that is to say you can't get more than the deficiency for a deficiency judgment. Anyhow, the rationale for the cap is to prevent fire sale prices.
