Finance experts, can you share an experience where collaboration with other financial professionals led to a better analysis outcome?

I am a certified divorce financial analyst (CDFA) trained in mediation and in collaborative law. The divorce process rises and falls on financial information: asset division, tax analysis, cash flow, business valuation, pension valuation. I routinely work with an accountant, a mortgage lender, an investment advisor and a pension specialist to ensure the best outcome for my client.
