RCW 58.28.180: Effect of informalities—Certificate or deed as prima facie evidence.

No mere informality, failure or omission on the part of any of the persons or officers named in this chapter invalidates the acts of such person or officer; but every certificate or deed granted to any person pursuant to the provisions of this chapter is prima facie evidence that all preliminary proceedings in relation thereto have been correctly taken and performed, and that the recitals therein are true and correct.
