I think the most significant thing is probably the timeframe. In our rules, when we adopted this and agreed to it, we felt initially that one year would be sufficient to develop these matrimonial laws. Through experience, we found that for many communities it simply wasn't possible. It takes a lot of community input and a lot of community meetings.
If anything, I would suggest that there be a longer timeframe, because you have elections that come into place with governing councils. Sometimes you have two years, sometimes three years, and for larger communities especially, there's a lot more communication involved. Even a one-year timeframe for us is a very short time, and some of our communities have not yet been able to finalize their matrimonial real property laws.
