That being said, Volkan, your father-in-law needs to understand that this form obligates him in exactly the same way that Form I-864 does. He is signing a legally binding contract saying that for as long as you are an LPR, he will financially support you. There is no material difference between a co-sponsor and a joint sponsor when it comes to legal liability; the I-864A is just a simpler form to fill out. If he believes that the I-864A somehow exonerates him from this responsibility he is mistaken and should have this perception corrected immediately.
