Now There Is A New Way To Tie The Knot. It is our position that limited liability companies, "LLCs", may prove to be the new marriage model. Marriage is presently available only to one man and one woman. LLCs are available to everyone, couples (of any sexual mix) who wish to pursue life together, a single parent family and groups of friends. Marriage is based on family law, limited liability companies are based on partnership law and the legal arrangement its "members" agree to.
