What Is The Oklahoma Law On Domestic Partner And Health Insurance? 
This is partially a legal question not an insurance question , as I am not an attorney you should seek legal council for the LAW on this topic . To my knowledge Oklahoma is not a State that recognizes Common Law Marriage or Domestic Partnership . At this time it is up to the individual employer if they want to include this coverage . As far as I know there is no mandate to force employers or insurance companies to provide coverage for either Common Law or Domestic Partnership at this time .
