Best family law lawyer. Helped me get joint custody of my son after mother tried to get me off the picture.

Very great attorney highly recommend him. He is extremely friendly knowledgeable and helpful and on time with his appointments when they here with my sister for divorce litigation and I’m very glad we did and highly recommend him to you.

I Cant Begin to Say How Greatful and Thankful I am for meeting Mr. Cosmas. Having Him By My side as My Lawyer Not Only Gave me the Peace of mind, But He far exceeded my expectations. That after Turbulent times of uncertainty. He Brought Hope confidence and Courage that I could not find on my own. He fought for my Joint 50/50 custody, he Went above and beyond, that assured Me I would Have Hope of seeing my Children again which I Love Them dearly, He Objected when I knew nothing of How Family Law works and its rules and Regulations,
Mr. Cosmas Helped In Unimaginable ways, that I my self Would have never Known How to defend nor object to,
His Cost Were Not High, but rather Reasonable, no hidden Fees for hours and Gave Me his undivided attention that showed true heart for my circumstances in Every Way To Show My Heart,
He Provided Peaceful approaches for the best interests of my children. He proved that I will do my best to Be a provider partaking to the best Interests of my children. He helped me clarify my Tax Exemptions, child support, and arrears payment, and By and Far I would Highly Recommend him to anyone needing a family Law Lawyer that will treat you with honesty integrity and Fairness , Thank You So much Mr. Cosmas God Bless You Abundantly.

This guy is amazing! Super knowledgeable experienced and court saavy. Honest, courteous , respectful and very reasonable. This man knows his way around family court. He didnt rake me over the coals with attourney fees and add ons either. He was honest about his time and didnt treat me like just a paycheck. He was very realistic with his expectations on the outcome of my case and didnt try to drag it out just to make money on me. I have a very vindictive baby mama who was swamping up my case with false allegations and lies...i felt like i was getting buried alive! I was extremely overwhelmed and started feeling hopeless. Mr Onyia brought the darkness to the light and methodically pieced apart my ex's story like a fortress made out of legos. She was unjustly trying to take full custody of our son and destroy me with all of her lies. ( Even making a false report to DCS) stressful! Cosmas did a fantastic job and i was awarded 50/50 custody. He was reasonably priced unlike most of the attourneys i spoke too before him, quoting me outrageous costs even before hearing my case. I got everything i asked for... 50/50 custody for less of the cost than i expected. Mr Onyia gave me piece of mind to sleep well at night and not to worry...now thats (PRICELESS!!!) THANK YOU SOOO MUCH MR ONYIA! You made a friend for life! God bless you.

My name is Nate, I was separated from my children 4 years ago. I had two previous lawyers who did absolutely nothing, but bill me for incompetence and only further extended my fight for the right to know my children. I met with Cosmas for the first time in 2016, and immediately, I felt like I was dealing with someone who, not only had an extensive knowledge of the Family Law procedures, but also a man who had compassion for what is right.
My case, without disclosing too much information here, was a very complex one, with major issues that are probably not the norm in your everyday Custody/parenting time case. Despite all the odds, I listened to Cosmas and even had several very frustrating arguments, all stemming from my own frustration with the laws that had put me in a place of extreme unjustness. A little over a year has passed since our first meeting, and yesterday, with Mr. Onyia representing me in a three hour trial/evidentiary hearing, I finally won big!
Mr. Onyia stayed focused on the pertinent matters in this trial, while the other party tried to continue there smear campaign, and further there unreasonableness. The judge didn’t want to hear or see what the other party attempted to enter or talk about in these proceedings, and they were cut short.
I know that I will be dealing with the other party for years to come, my children being very young still. Knowing this, but also having complete confidence in Cosmas’s abilities as a lawyer, puts my mind at ease today. I owe this man a great deal of gratitude and if not for his effforts, I would still be paying to see my children through supervised visitation. I sincerely wish him and his family great prosperity and happiness. Thank you Sir!
