If you tell the judge exactly what you said in your question (about the blogs pertaining to single days in the past, and your current earnings not being anywhere near that anymore) then you should be covered for any future support payment decisions the judge makes.

Looking back into the past, the judge, logically, would be able to say that you were earning a lot more back then -- more than your ex thought you were earning.

If there's some agreement or court order in effect that you have to keep your ex posted as to any significant change in your income, and the judge finds that you should have told your ex that you were making a lot of money all of a sudden back then, it seems logical that a judge could order some adjustment to credit some money over to your ex based on your high earnings for that brief period of time in the past.

But it also seems reasonable to assume that your current pregnancy and your hard luck with losing your clients ought to be taken into account to dismiss any claim brought by your ex, unless there's a major amount of money involved that had a tremendous impact on support payments, and was deliberately concealed by you.

Assuming that's not the case, I would think a normal approach would be for the judge to look at copies of your past tax returns and compare them to your ex's tax returns, then arrive at a decision as to whether some adjustment should be made to compensate for a few months in the past, or whether the matter should be dismissed as trivial.

Since you've been so honest on your tax returns, it makes sense to assume you'd make an excellent impression in court. Based on your whole situation, I'd bet on you winning against any petty attack by your ex.

As to evidence, there's good evidence (strong evidence) and weak evidence. In my experience with family courts, copies of federal tax returns generally are the criteria for determining support payments, not blogs.

Yeah, I think I'm going to bring my tax returns, plus the emails/articles about some of my clients going under.
