If you were separated on 08/01/23 and your gross pay was say $5,000 per month, but then you got a promotion on 09/01/23 and your gross pay was bumped up to $6000 per month, which pay is used for spousal support, alimony, etc?

I’m going to ask my lawyer, but I am under the impression that whatever financially happens to you or for you after date of separation is considered outside of marital assets.

If I assumed a debt after 08/01/23 I couldn’t expect her to share in that debt, from what I understand, does that hold true for increases in compensation?

Do I have wishful thinking or is this true?
