Why Missouri is different
Missouri's service contract law excludes agreements or warranties which provide for the service, repair, replacement or maintenance of the systems, appliances and structural components of residential or commercial real property. Its rules therefore do not reach home warranties. For the service contracts it does cover, providers register with the director of the Department of Commerce and Insurance and back their contracts with reserves, insurance or a $100 million net worth.

§ 03Common questions for Missouri
When does coverage start after I buy a plan?
When the waiting period in your contract ends. Providers set different lengths. Liberty Home Guard's sample policy starts coverage 30 days after purchase and requires covered items to be in working order that day. American Home Shield's 2024 sample plan agreement shows an initial waiting period of 0 days. Under Liberty's terms, a covered item that breaks on day 20 falls inside that 30-day holding period and is not covered, so read each provider's sample contract before you buy.
Can I buy a plan after something has already broken?
You can buy one, but the two sample contracts we read would not pay for a breakdown you already have. Liberty Home Guard's sample policy "does not cover any known or unknown pre-existing conditions." American Home Shield's 2024 sample plan agreement says a covered breakdown "must occur during the Plan Agreement Term," and it excludes earlier breakdowns that "were either known by you or were reasonably detectable by you."
