>>TIAA-CREF
As it happens I've just researched this, but naturally for my own particular case. I haven't made contributions since the 80s. Since then there have been lots of new possibilities and options.
In my case and I'm reasonably sure this applies to almost anything contributed before about 1990, from regular contracts you can't take out anything early, period (with certain exceptions, such as leaving an employer with a small-sized account). I believe some more recent contracts may allow certain hardship withdrawals (medical, say), provided the employers plan allows it.
That's for regular contracts. If you bought supplemental cashable contracts, you can cash them in for tax due plus a 10% penalty. If you did that, though, you would know it. BTW, when I bought them there was no penalty. Later congress put on the 10% penalty retroactively. Only the government can change a contract after it's been entered. Talk about full faith and credit ... sorry, never mind.
Anyhow, with these minor exceptions, no withdrawals. Till retirement.
However, you CAN roll the plan into an IRA, and you will then be subject to the IRA rules. The details depend on the plan. In my case I contributed under two institution plans. In one, I can roll to an IRA any time. In the second there are limits till age 55. I believe you can roll at age 59 1/2 regardless of the plan. Oh, yeah, I think you CAN'T be making current TIAA/CREF contributions, though that may vary by institution plan too. Also, you can do a partial rollover.
TIAA-CREF can look the info up for you, and they are really very helpful. Call the toll-free number. I warn you they will have difficulty understanding that you might ACTUALLY think of taking your money away from them, though <g>. And, of course, there may be other limitations, considerations, and options depending on the plan and when you contributed.
