So what you're saying, is the next lawyer in the chain, can always fool the prior?

If that is the case, then is an employment contract not the same? Suddenly, your contract now has you working for minimum wage?

Because 'next lawyer in chain' can always destroy all prior contracts?

So it is all pointless? Or are these lawyers only able to negate all equity claims?

Thus, the founders always get nothing? Or is it the VCs which get their equity diluted to 0, all the time, because no one can make a solid equity contract?

Note: if this happened to you, more info may aid us all.
