you should contact the plan administrators
as I said in your other Q
you will lose at leat 30% of vested value
20% to taxes and 10% to the IRS for early withdrawl penelaties

Fork over the taxes plus a penalty to the government (about 40% of what you've saved) and if there's anything left, it'll be yours. Also, be ready for a big fight cause I hear that the plan administrators are refusing to do it

usually your old employer will send the correct paperwork to you automatically. but I must warn you, there is a close to 60% penalty to cash out....the IRS will feed ya the biggest slice of dick pie on that one bud....good luck...oh, if your old employer doesnt send the stuff to you, just get ahold of the HR department, they should be able to help ya.

i'd think you'd get penalized fairly heavily for early withdrawal. Are you sure about this?
