Assuming you have a strong business-minded attorney and a good relationship with them, ask them in an email. Skip the meeting (expensive). The answer, like most legal items, is complicated, but a good attorney can help you wade through it with a two-line email response. You just need to ask it the right way.

In case it helps, here's the full email last time I had this issue:

> Quick question...should I bother to formally dissolve [company]? We've all moved on to other projects so I'm going to officially add [company] to the deadpool. No more work will be done on it (although we might open source a few components for the greater good), and there's $90 left in the bank account...probably enough to pay for this email :)
