SDCL § 43-11-31: Power as a lien upon real property.

A power is a lien upon the real property which it embraces from the time the instrument in which it is contained takes effect; except that against creditors, purchasers, and encumbrancers, in good faith and without notice, from any person having an estate in such real property, the power is a lien only from the time the instrument in which it is contained is duly recorded.
