One of the greatest cost-reducing things I did was respond directly to OP's many harassing and duplicate requests for information (with my attorney's review).
If you are represented by an attorney, you cannot directly communicate with the opposing counsel.
Would you care to clarify what exactly you did?
1. My counsel would receive letters & requests not directly related to the divorce settlement (i.e., "Please remind your client that he needs to pay for a plumber to come fix a leaky faucet at the family home", and "Please remind your client that he's responsible for snow removal", and my favorite "Please provide ALL sources of income" (despite only having one job and previously handing over 12 months of pay statements & W2).
2. Letters would be handed over to me, and I would draft detailed responses, addressed to MY attorney.
3. My counsel would review these, we might discuss them briefly, and he'd send them to OP along with a cover letter which basically said "see my client's response"
4. We'd wait & repeat with subsequent responses.
Basically, her counsel was trying to drive up my legal fees and harass me with easily addressed issues that actually were non-issues. My attorney was a good guy who recognized what was going on & felt that I was capable of responding appropriately. If I had wished, he would have responded to these directly, but at a cost.
