I think it's true that it is largely an amendment to the "standard marriage contract" as reflected by the state's laws (I have one and spent a lot of time in researching it). But, that amendment, just as any contractual amendment, can change the original agreement dramatically and across many, many key terms. As my attorney in the matter said to me, "You can let the state decide in the future what happens if you get divorced, or you and your partner can decide it now."
