Although no two divorces are exactly the same, there are a number of things that can be done to make the process more efficient.
First, even before meeting with your attorney, organize your paperwork so that your attorney will have a more accurate idea of the financial issues: make copies of tax returns, bank statements, credit card statements, loan agreements, deeds, and other financial records. If there will be a claim that some assets were premarital, assemble proof of when the asset was acquired or account opened, the source of funds, and copies of old checks, deposit slips, etc.
Next, make sure you have your own credit card and checking/savings account, separate and apart from your spouse.
Finally, start considering realistic long terms goals, and obligations: Do you want to stay in the house? Can you afford to stay in the house? How will the children’s college be paid for? Do you have health insurance?
