I was given last minute notice that I had to appear in court for a legal matter. I had one day to find representation and when I called Cooper Family Law, they took the time to listen to me and responded swiftly. Mr. Zachary Bartman contacted me to discuss the case and assured me that he would meet me in court the following day. Mr. Bartman exceeded my expectations in every way when it came to handling my case. He addressed any questions or concerns that I may have had. While I hated having to be … More in court, Mr. Bartman helped to make it more bearable for me. I can’t say enough good things about Mr. Bartman and this firm. In the end we got the desired outcome and I don’t believe it would have been possible without him. I am extremely appreciative for your help throughout this process, Zachary. I would 100 percent recommend this firm and if the need arises in the future, I will have them represent me. If you find yourself reading my review, please understand that I hate leaving reviews so that should speak to the level of professionalism that Zachary displayed. Don’t hesitate to contact Cooper Family Law if you need assistance.
Daril ★★★★★
Zach did a excellent job in handling my pfa case. Zach is very intelligent and sharp as a tac in handling the false accusations made against me. Most importantly you should consider hiring him to help you defend against a pfa because when it's time for him to do his job, he takes control of the court room and gets it done. It doesn't matter what kind of lies you are up against and the new lies that come out during court Zach puts it down thank you for the awesome job. Robert Nimchuk

When I first realized I needed a lawyer for my custody situation, I simply googled custody law and chose to call Cooper Family Law because I had heard the name before through some advertisement somewhere. My consultation with Zachary Bartman was smooth and reassuring but when I met him in person I noticed he looked super young, and I feared he lacked the experience needed to produce my desired outcome.My ex refused to concede any ground at all, and we were forced to go to a custody trial. When I … More tell you Zachary Bartman completely overwhelmed opposing counsel and made their arguments appear foolish to our trial judge, I am not exaggerating. In fact, I felt foolish for judging a book by its cover. He was able to get me what my family and I had set out for despite a mountain of lies and nonsense impeding us. I now cherish the time I get to spend with my son, and I thank God I picked up the phone to call Cooper Family Law everyday. I will highly recommend Mr. Bartman to anyone in need of one of the best custody lawyers in Philly/Delco/Montco areas, and if I am ever in another pickle I know he’s the guy to get the job done.

Having to navigate the court system can be an overwhelmingly stressful experience for many individuals. However, by seeking legal representation through Cooper Family Law, these feelings can be greatly reduced. Over the past three years, I have had the opportunity to be represented by four different lawyers at this reputable law firm, particularly in cases involving custody, child support, and a personal protection order (PFA). Without exception, my experience with this law firm has been exceptional, … More consistently resulting in positive outcomes. It is with deep gratitude that I write this review not only to express my appreciation for the entire law firm, but also to specifically acknowledge the invaluable contributions of Zachary Bartman.

I was handling a custody arrangement through the court on my own. Things got somewhat complicated and I needed some help. I was a previous client of Sadek and Cooper for another legal matter and decided to contact Cooper Family Law for help since they did so well with my case.

I wish I would’ve retain their services at the start to help … More me better navigate this court system. Thanks again Patrick!
