Unfortunately, this is not a "survivor's forum" for general exchange of tips and strategies and there are better sites for that. You should consult with a family law attorney who can give you all the tips and stratgies for the litigation in one meeting, explaining to him you need advice, and don't want representation.
If you found this "helpful" or "best answer," please click it with my appreciation. My response is for educational purposes and does not constitute legal advice nor creates an attorney client relationship which requires all the details and a personal conference.Ask a similar question
No. Just as I cannot perform open heart surgery on myself so you cannot go to a court and do it yourself. Court is not an intuitive thing and court is not a box with buttons you push in the correct sequence. There are as many variations to a case as there are facts in a case. Facts (the input) all intertwine with the "law" (the function) to produce output. There is no "tip" as to how to optimize your output.
I am also quite surprised you ask about "high income cases" but you appear to want to save money on a lawyer in a child support case. That's like wanting to save money on a transmission fluid change that leads to a far more expensive transmission repair and car replacement. The few thousand dollars you save now on your support case can translate into hundreds of thousands of dollars in overpaid support which can never be refunded to you. It befuddles me as to what you are doing.
I do wish you the best of luck. Remember that in today's America, you cannot have a child (UCCJEA, CAPTA, ASFA, CSSA ... ) without also having a family lawyer.Ask a similar question
