Why does the separation date matter, which is requested in the Petition for Dissolution?
It is important because any income earned as a result of work done after the separation date belongs to the person who earned it and any debts incurred after the separation date is of the person who incurred the debt. Also, some assets are valued on the date of separation. Separation is the date in which you believed that the marriage was truly over and there is no hope of reconciliation. One spouse may have a different belief as to what is the separation date.
