If you are planning to leave your partner and depending on the circumstances, especially if your partner has their own business, you need to get your ducks in a row. You need to document what your lifestyle is. You need to make copies of your tax documents. Make copies of credit card statements. You need to get profit and loss statements from the business. The more information you have about your life style before you separate, the more ammunication you are going to have for child support for your children. What you do not want is a he said, she said, especially if income is coming in through a business where the partner has control over the money that is declared. So the best divorce possible happens when you are organized and you have as much evidence and information as you need to get the support that you are going to need after the divorce.
