You need to have a SERIOUS conversation with their dad. When boys begin adolescence, they need a very strong father in their life. I have a sons 24, 19, 15, 10 and 8. You and dad need to lay out the ground rules, follow them both TO THE LETTER at your place and his place. The rules need to have consequences attached--both negative for disobedience and positive for obedience. These things need to be followed with beautiful ruthlessness---with overflowing love be unbending.
I'm not sure how long you've been divorced, but it's no shock that the boys are acting up. As far as them talking to a counselor, you just get them there and let the counselor figure out the talking part.
Boys a so much fun to raise---truly. I H. with firm, consistent rules, abundant love and parental cooperation, you can work through the rough spots.
