First, thank you for your service and I am deeply saddened to hear about your injury.
The answer would depend on many things. Perhaps, the most important is your state and its laws. I would think that an insurance settlement for a personal injury would not be divisible in a divorce. Of course, I would probably need to know much more about the nature of the settlement.
In a state that has fault based divorce laws, infidelity may impact on spousal support issues. That is, perhaps, how your insurance comes into play. It does not generally impact property divisions, In a no fault state, the infidelity has no impact on either issue.
The bottom line is that your divorce lawyer would have the best information on that issue. Your worker's compensation attorney would not. Sometimes the right answer is not what you wish to hear. You may wish to consult with another divorce lawyer in your state and if the answer is the same, you have your answer.
