Well this may sound harsh, and I don't know the specific circumstances about your request, so just consider this food for thought.

Suze Orman says no, don't co-sign any loans that you are not prepared to pay off yourself.

Student loans are not dischargeable in a bankruptcy. They never go away, and the interest keeps accruing. Students are taking out tens of thousands, if not more in student loans. Students attending ivy league colleges might end up with $300,000 in student loans, and no job. That's like a mortgage. Think very carefully before you co-sign any student loans.

If a bank won't give credit to someone without a co-signer, do you really want to grant credit to that same person, and then run the risk of having to pay it off yourself?

If the loan amount is just a few thousand for your own child, that may be a different story, and much easier if you get stuck for the repayment. But don't lose sight of the fact that you may still have to pay it off.
