As a non profit we could not place claims for non payment of dues. The non profit manages our non road property such a boat launch and beach and there is a budget for that, and the Road Association has a budget for the road.
As you make me think it through, it occurs to me that one could skip paying the non profit dues without recourse.
Others wiser than me may weigh in, but I don't think you convert. You dissolve the non profit (google has the steps) and start over using the steps to create a statutory association. Or create the statutory then dissolve - not sure.
