If you had a retirement plan account with your former employer, chances are that you can choose to withdraw your money from the plan. To do this, contact your former employer and ask them to send you a distribution form.
If you choose to withdraw the money from your retirement plan account, you then have to decide what to do with it. If you take the money and spend it, you will owe federal and state taxes as well as an additional 10% penalty tax on the entire distribution if you're under age 55.
The better alternative is to roll the money into an IRA. The entire distribution will be processed as a "direct rollover" to a Traditional (or Rollover) IRA. Since this transaction will not be taxable, you will owe no taxes until you withdraw money from your IRA.
