Delaware Code Title 8. Corporations § 619. Construction of chapter

(1) This chapter shall not be construed as repealing, modifying or restricting the applicable provisions of law relating to incorporations, sales of securities, or regulating the several professions enumerated in this chapter, except insofar as such laws conflict with this chapter.

(2)  The provisions in this chapter authorizing “qualified related professional services” shall not create any vested rights to practice professions in any particular combination.  If by reason of a change in law, rule or regulation, the right to practice professions in any particular combination is modified or terminated, each existing professional corporation rendering a combination of professional services previously permitted as qualified related professional services shall promptly reduce the specific kinds of professional services rendered by the professional corporation or shall otherwise reconstitute itself so as to comply with the currently applicable restrictions applicable to each of the professions involved.
