Act of 1871. search it up. You can also realize it by yourself by looking at all your legal documents. They will all be sourced from the Birth Certificate. This is the legal corporate fiction. No contract can be done without it anymore.

I, too, would like to see some evidence of this claim.

same i posted on a similar thread asking for some proof or something. i like the idea of these "TRUE or FALSE:" topics, maybe stickied, or at least linked in the sidebar for when wild theories get running

Seems to require a pretty esoteric interpretation of the legalese. They use arguments like "the capitalization is different." e.g. "the United States of America" is a different entity than "the united states". But there is no clear glossary anywhere which specifically states this. And I've had commercial contracts where details like this were not considered relevant.

So I vote false. Then again, the law is complicated enough that a judge could find a precedent to support almost any position if they looked hard enough. But this seems like a stretch.
