> I understand, and accept if a family wants to have 3 adults. Or 4 adults. I'm even OK if children are raised in that atmosphere.
Do you think that it serves the interests of the rest of society to offer special benefits and protections to 3-4 person unions? If so, what? Is there a size limit on such unions? And under what conditions do they begin/end? If one person leaves the union, is the entire union abolished? What if two leave together? Can you have a divorce that turns one union into two or more? What happens with property and/or child custody in that case?
Yes: questions like these need to be asked, and at least tentatively answered, before legally sanctioned poly marriage can even be put on the table for discussion. In particular, there needs to be a clear idea of what happens to the children under the various possible scenarios. I don't think just letting people make whatever agreements they want is going to fly, at least not once any children at all are involved. These things could get very very complicated. There needs to be at least a framework, a sense of what structures can work, as borne out by experience.
I have a suspicion that in the end, it will turn out to be best not to make any special legal provision for poly marriages. The law will recognize couples, and those couples will be free, as indeed they are today, to make whatever informal arrangements with other parties they wish. In a few areas -- hospital visitation rights are a good example -- I think it would work to detach the right from legal marriage altogether, and just let people declare who may visit them, etc. But the legal system has to know who is legally responsible for each child, and I don't think it can be more than two people -- even two is often problematic, as we know from long experience.
You make a corporate charter, issue shares and have vesting schedules!
Joking aside, you'll notice a lot of parallels between a business partnership structure and marriages in general. Including the liability parts!
"Personal liability is a major concern if you use a general partnership to structure your business. Like sole proprietors, general partners are personally liable for the partnership's obligations and debts. Each general partner can act on behalf of the partnership, take out loans and make decisions that will affect and be binding on all the partners"
