Do you really need a lawyer here? Presumably the mechanics are pretty simple: you're vested halfway to your share (in what is probably going to be worthless equity), which is what you walk away with.

I ask this because I have on several occasions lawyered up (sometimes adversarially, sometimes just to keep my own ducks in a row) during separations and (if you're working with someone serious who is qualified to manage a founder separation) it's always expensive, but not always valuable.

I also ask this because this is the Nth "I'm splitting up from my startup" I've participated in, and I've noticed that for better or worse, this community has a bias towards dramatically satisfying resolutions, like ensuring for instance that each founder in a doomed startup receives precisely the allocation of company assets that they're entitled to. In the real world, the smart play is often just to walk away.
