Thanks. In this case, your rights to any settlement/judgment that results from his employment suit will be limited to the extent that it is part of the martial property.
Here's what I mean: In Virginia, all property acquired by a married couple after the official date of the marriage is considered "marital property," and thus subject to the laws of property division upon divorce. So, if your husband's case settles or if he is awarded damages following a trial, any money he receives will be part of your marital property IF he receives it while you're still married. It's important to note that the fact that you're separated does not diminish your entitlement to this money. You will not be entitled to any of it only if the settlement/judgment occurs after you are divorced.
Now, it sounds like this lawsuit started a few months ago, and you're expecting that you will probably divorce in Feb/March 2018. Based on this timeline, my experience tells me that you will be divorced well before this case ends. These types of cases can easily take 2 years - even when they settle, which they usually do. What this means is that you will probably not be entitled to any share of the outcome of his case. Sorry.
It sounds like there's hope of reconciliation? I hope so, and I wish you luck. But if things keep heading towards divorce, your attorney should try to secure for you a share of your husband's case proceeds. As explained above, under the law, your husband does not have to share it with you. However, there is no reason why the two of you cannot agree to split it. This can be negotiated by your attorney as part of the overall divorce settlement. Your attorney could, for instance, threaten to litigate the matter, and thus induce your husband to share. In this regard, it will be important for you to find a shrewd family lawyer who can aggressively advocate for you.
I'll stand by ready to answer any follow up questions you may have. Otherwise, I hope this helps! If so, please be sure to rate my answer, since that is the only way I can receive credit.
