SDCL § 36-18A-38: Practice permitted recipient of license--Use of titles--License as evidence.

The recipient of a license issued under this chapter may practice engineering, architecture, land surveying, landscape architecture, petroleum release assessment, or petroleum release remediation and use the appropriate title professional engineer, architect, land surveyor, landscape architect, petroleum release assessor, or petroleum release remediator. A licensee may use a title either with or without prefixing the word, licensed or registered. No licensee may practice a profession or use a title unless the license specifically permits such practice and usage. An unrevoked and unexpired license issued as provided in this chapter is presumptive evidence in all courts and places that the person named is legally licensed.
