About William Halaz III, Litigation Partner

William J. Halaz III said being able to help a father claim his rights with regard to custody of a child is one of the more enjoyable parts of being a family law attorney.

“It’s rarely an ideal situation; just a father trying to do the right thing,” he said of these cases.

In order to advocate for a client’s best interests, Mr. Halaz said open lines of communication between an attorney and client are key.

“If a client is not open and honest with you it’s difficult to prepare and represent their interests as fully as possible,” he said. “You need to develop a relationship with them so that way we can both trust each other and present their case the best way possible.”

Mr. Halaz said patience is the most important trait to have during a family law case.

“This area of law is wrought with emotion, and rightly so,” he said. “However, keeping a cool head when things get heated can be invaluable.”

Real-Life Experiences
Reviews from Our Past Clients
“Wow, there’s so much I have to say about Cordell & Cordell. I walked in with tears in my eyes hopeless because everything was taken a way from me. Father of 7 children that was told there’s no hope for the fathers now days. Cordell & Cordell welcomed me in their hands and proved everyone wrong. They were there for me and my children until the end.”
– Izet K.
“It took years for me to come to a decision to end my marriage. I sought a law firm that is focused and prepared for trial if need be, and seeks to give me the best outcome possible. Cordell and Cordell has performed very well and is very supportive during this difficult time. I have full confidence in my representation and recommend them.”
– Mason B.
“Cordell & Cordell has been really helpful in all my divorce and custody-related needs, even when I have been struggling to make ends meet, they remained communicative regarding my account. I am very grateful to have had such amazing representation in the most important court case of my life! Thank you!”
– Amanda H
“Divorce is hard enough without trying to find a Lawyer who will truly work for you. I had several conversations with Lawyers that seemed only interested in winning somehow. No one wins in a divorce. I should have went to Cordell & Cordell first so I would have avoided a lot of headaches. I met a group of people that genuinely care for you.”
– Mark L.
