Once the decision has been made and you know for certain that you are getting divorced, then there are many matters that call for swift and decisive action. Even if you are feeling emotionally pummeled by the prospect of ending your relationship, you need to be very proactive in regard to protecting your assets. Simply put, you cannot afford to let your sadness or anxiety cause you to delay doing what is necessary.
One of the most important things you can do is extricate yourself financially from your soon-to-be ex-spouse. So long as you have joint accounts, your ex can move or spend those funds with impunity. It is not unheard of for a spouse to empty a joint bank account, so you want to open your own accounts as soon as possible. This will act to keep your spouse from having access to your future income.
You also need to separate your debts from your spouse's. Specifically, you want to contact your credit-card issuers and find out about either closing any joint accounts or have your spouse removed from the accounts. You don't need your spouse running amok with the plastic and leaving you with half of a huge debt.
These are just some preliminary moves you can make to protect your financial interests. The divorce process is typically multi-faceted and encompasses many areas of your life. You could likely use the aid of knowledgeable attorney when working through such complex issues as property division, child support, and child custody.
