This is a very enlightened legal position. Is it fairly straightforward in terms of enforcement? It sounds like something I wish my state had as it would prevent long term partners from being left out in the cold by resentful family members. I have dealt with this problems several times over the years.
This is fantastic, isn't it? Although now, same sex couples can marry and civil unions are available to seniors who would lose benefits from marrying, not everyone has signed up for these kinds of relationships. Especially people who resent having been refused those options for so many years.
This statute is also beneficial for people who try to use non-marriage as an excuse to mistreat their partner, as in "we're not married so you don't have any say in this."
Unfortunately, most people don't know about it and so are taken advantage of by vindictive family members.
Does it kick in as a matter of law, or must these people register somewhere?
It's a matter of law and quite often used when people specifically TRY to avoid marriage.
I really like that. I have practiced family law and probate for many years and this would solve a myriad of problems.
