How can I stop paying child support after finding out the child is not mine?

You should choose a divorce attorney based on their experience, their knowledge of the law of domestic relations, divorce, custody, alimony, child support. All those are going to be issues in most divorces.

You should choose an attorney that's experienced in the court room and that's not afraid to take things to trial. Most of all, you should choose an attorney that's knowledgeable and that you can trust. If you can't trust your attorney to tell your attorney the most, probably some of the most intimate things in your life, then you're not going to have a good relationship and success is going to be limited because of that tug in that relationship. It's really important to develop some rapport and hire an attorney in a law firm that not only is capable and willing, but is trustworthy.
