Please bear with me as the ESOP is new ground for me and I am leaving a company 70 percent vested in one.

From what I have seen is it correct that I will not expect to see any pay out of this account for quite a few years..?
Is that up to the discression of the company that I am leaving ?
What is the maxium time frame that they can wait under law until payments start..?

Your information is much appreciated -

Some aspects can vary from plan to plan so it's dangerous to try to apply generalizations to an individual situation. The best place to start is with the person at your company who handles employee benefits and the ESOP. Your benefits administrator will be able to explain what options will be available to you after leaving the company.

Ask for another copy of the summary plan description and ask if it is up-to-date.
