Missouri Options Statutes

[Casey Mericle]

I'm interested in finding out if there is a Missouri Statute regarding real estate options.  Specifically, I'd like to know if there's a stated maximum allowable time limit?  Can options run in perpetuity?  If anyone could point me to a link or the exact chapter and section that would be great.

@Bill Gulley with your background I think you may be a prime candidate to answer this one, but others certainly may know as well.
