Why the order falls this way

Of the grade, 32% rests on three-year bill and 32% on what the money buys; renewal handling, local rules match and pricing openness share the remaining 36%. What the money buys decided Kentucky.

Mainstay's agent plan grades higher on coverage: served papers are scanned the same business day at no fee, the price is identical in all fifty states and three government mailings a year are scanned free. KY Registered Agent.org wins on cost, and the margin is thin.

Every criterion and weight is listed on How we rank.
