Hi. I assume that you're referring to whether or not a MAN should seek counsel from a woman, not a woman from another woman.
I know that of course the Bible speaks of women being capable of having great discernment (such as Nabal's wife Abigail), and there is an instance, in Acts 18, where a Godly woman teaches a man the Scriptures: Priscilla, Aquila's wife. It says they both "explained to him (Apollos) the way of God more accurately." She must have been a very wise woman, because Apollos was described as already "competent in the Scriptures."
But Priscilla didn't teach him alone, she was at the side of her husband. So if you're a man, it's safest to get counsel (on serious and/or sensitive matters) from a Godly man, or from a Godly couple.
I think your friend is talking about when a church member is involved in open sin -- you would go to that person once, rebuking them in love, and if the brother/sister is not restored, you take one more person with you to try again. If that fails, bring that brother/sister before the church. I can't think of a "process" for seeking counsel on a matter, but maybe it's there and I don't realize it.
I wish I had time to look up more Scriptures for you, but anyway I hope this helps!
