That's more of a legal question that you would need to ask the legal authority that dealt with the divorce. But the bottom line is, if you get a K-1 then you'll have to report it on your own tax return.
I would expect the partnership to show the departure of one partner, and the arrival of a new partner. But that all depends on the conditions as specified in the legal documents of the divorce. But as a partner, what the parntership return shows is not your concern (unless you are the CFO of the parntership that prepares the 1065). Your only concern is reporting the K-1 on your personal tax return if you actually receive one. I would expect you to have received one by now though.
