Divorce Attorney
Mark Brent is a great divorce attorney. He made a very emotional and stressful process easier. He is very knowledgeable and compassionate. He was able to guide me through the process and made sure that I clearly understood everything that needed to be done. We were able to complete the process in under 4 months. I am so grateful he handled this for me.

Child Support
Mr. Brent and his team did a very good job taking care of my child support case. He was very knowledgeable and informative. He answered all the questions I asked and never left me wondering. He represented me at court when I wasn't able to and I'm extremely grateful for that. I would definitely recommend Mr. Brent and his team to anyone seeking legal assistance.

Easy smooth divorce
I didn’t think that the divorce process could be so smooth but Mark Brent and his team made it happen! I hired him in late January and my divorce was finalized mid-March. They handled everything and I mean EVERYTHING. They kept great communication through the whole process with me as well. I couldn’t have asked for a better firm to help me with all of this. Thank you so much!

Awesome dude
He's keeping me on track and doesn't like...I've tried out many different attorneys before hiring him and at first it was weird for me to hand over my life to another person but I can see as I'm in my discovery phase that he wants as much info as he can to do t h e best job he can...organisation is key... Also I talked to the opposition's lawyer and he said I'm in very good hands so that tells you that there might not be a better lawyer in this area than him..

Glad I Hired Mark
I hired Mark to represent me when I sought an Order of Protection against an abusive family member. I really needed the peace of mind of having someone represent me, as I know nothing about law and would probably crumple under the pressure if I tried to represent myself. Mark made me feel much better about the situation. He laid out all the facts for me and went over what would happen in court. When the court date came, he knew exactly what to say to the judge, and I really wonder if I would have won if Mark had not been representing me. He clearly cared about my case and he was kind and friendly to work with, but he is exactly as aggressive as he needs to be in court in order to win. He was very professional and prepared, and clearly knows his stuff. I highly recommend him!

Simply The Best
Mark was my attorney in my recent separation and divorce. What impressed me more than anything about him was not only his exceptional legal knowledge but his ability to advise dispassionately showing you upside and downside of the situation. Moreover, he helped me to leave the emotions out of the decision-making process and was always well-prepared, thorough and professional. Mark is indeed a one of a kind, family lawyer and I would highly recommend him.

Highly effective in every way
Mark Brent handled my separation and divorce with courtesy and professionalism. He advocated for me in every way throughout the process, always had my best interests in mind, and was available whenever needed to answer any questions I had, no matter how big or small. He provided a very satisfactory outcome to a complicated situation. I have recommended him and his firm many times without hesitation, and have returned myself as the need arose.

I Made The Right Choice
After 20 yrs. of marriage, I was positive it was time to divorce. Although I consider myself a strong woman, this was one of the most emotional things I have ever gone through. It was exceptionally hard because I had to consider what was best for our child. Not only did Mr. Brent help me and advise me of all my options, I could tell he actually cared. He treated me like a person with feelings and not just a client. The words that come to mind when I think of Mr. Brent are compassionate, caring, knowledgeable, professional, and an overall wonderful attorney. I was more than satisfied with Mr.Brent and highly recommend him to anyone in need of a lawyer.

Excellent Guidance and Highly Effective
Mr. Mark Brent is an award-winning attorney and author of Divorce Proceedings in Illinois. His awards adorn the office walls of the Drendel & Jansons Law Group, but only begin to speak for who he is as an attorney. To say he is outstanding is not sufficient. My 29-year marriage was shattered with my husband's arrest and a protective order. Six months post-arrest, he removed all marital funds from our bank accounts and ceased paying our marital bills. I called Mr. Brent to end my marriage. My case included a home foreclosure, personal property division, temporary maintenance, interstate move, bankruptcy and two children that needed to continue their college educations. Mr. Brent lead me through every step with his controlled and knowledgeable expertise. Mark is straight-forward honest, cost-conscious and efficient. You can count on his timely responses and patient listening to solve problems. He knows the law and his job. If you are thinking of divorce, purchase his book. If you need a family law attorney, he should be your first call. Mr. Brent will only tell you what you should hear and never mislead you with what you want to hear. Listen to him, trust him to do his job and you will move forward to a new life. My children and I are in a better place today because God blessed us with Mr. Mark Brent.

Effective Lawyer
I hired Mark to represent me during my divorce. He handled my case effectively and with zeal. His fees were fair and he was very responsive to my questions. I highly recommend Mark.

Great guy
Mark did a wonderful job on the tail end of my case. Even though I didn't win, he did the best he could coming on board so late. His prices weren't crazy and there were even times he dicounted his prices for me. I think he was very fair and honest. Would recommend him.

Review from JR Herrera
Before I chose Mark Brent to represent me I had interviewed other attorneys. I opted for Mark because he is an aggressive, knowledgeable, experienced attorney. He always tells you the status of the case in an honest manner, he gets down to the point and says it how it is. If the case doesn't have any signs of succeeding he will let you know he doesn't give you false hope. Throughout my long divorce he was always fighting to resolve the case as favorable to me as possible.

Effective and efficient lawyer that gets positive results
I would trust my life with Mark. He is a great Lawyer. He always succeeds and goes the extra mile to keep his clients informed and happy. I have hired mark on two occasions and both times got the exact results I desired. He puts his clients first in all aspects!

Mark Brent
Mark told me what he needed for my case and we worked well together. Part of having a good attorney is also being a good client and giving your attorney accurate information. My ex had the worst, most disorganized attorneys and he had to always get them back on track. We would still be arguing if it wasn't for Mark pushing to get this done.

Divorce lawyer
Mark is firm but fair when it came to my rights as a father for my kids. He got me primary custody. My divorce was a long process but mark made sure he set me up to get what I needed for me and my children. He will go head to head with the best and come out on top. He explained everything to me and always did what was best

Maintenance Reduction
9 months ago I met with Mark Brent regarding filing a reduction of maintenance to my ex. I was currently paying her $2,900 a month (and had been for 10 years). At that initial meeting Mark wrote down the number $1,387 on a piece of paper and said, “I’m not going to guarantee I can get you that number but I will get you close”. After 9 months, the only activity that has occurred is Mark invoicing me just over $12k in his fees and the judge recently granting her attorney another $7,500 in his fee’s. I met with Mark to discuss the current status of the case - he then advised me that we accept opposing councils offer to only reduce maintenance to $2450 per month. I spent $20 grand to save $450 a month for the next two years (I turn 65 in 2 years). I decided it was in my best interests to find a new Attorney to represent me in this maintenance review case. I was highly disappointed with Mark’s performance - opposing council was 3 steps ahead of him the entre 9 months.
