Hence the reason I asked if a subpoena was presented. Just trying to make the OP come up with the correct answer himself. ;)

There are not steps,

First you are not clear why an attorney is asking questions, my general rule, if it is not for my benefit, I refuse to answer any questions, unless it is required by court order.

If this is a legal case against you, just refuse to answer any question,

If this is a case to help or hurt someone else, answer only those questions you want to, but understand if go to trial, they may ask you anything under oath, Then you have to answer, unless other attorney objects.

Now, if this is about a person in your company, unless there is a court order, requriing the information, you do not give out anything.
** some companies will, there is no real law protecting the information, but as a practice it is not given out
