EXCELLENT representation in divorce

Erin and her team represented me in my divorce. From beginning to end she was there for me, answering questions and offering excellent legal advice that culminated in a divorce decree that put my children and their well-being at the center of everything. I HIGHLY recommend Erin and her team.

HIHGLY RECOMENDED!!!!

Erin and her team are amazing! Erin is so skilled at what she does. Erin supported me with custody/parenting plan and child support claims. She is practical, logical, gives you all your options, and supports your decisions. Erin is able to help you make rational decisions in very emotionally cha...rged situations. Yet, she will fight for you!

Do yourself a favor and HIRE ERIN!!!

I didn't plan on hiring a lawyer. I filed pro se and had to hire one when my ex went and hired his. After looking and asking around, I decided to hire Erin. BEST MONEY EVER SPENT!!! My ex's lawyer was one mean s.o.b and fought me on every issue, trying to delay the process and get me to concede a n...umber of things. Erin fought for me and my kids and our best interests all along the way. Either she or one of her staff answered every question in a very timely manner, thoroughly so I could understand it, either via email or on the telephone. No question was left unanswered or treated as stupid or unimportant. They were all so supportive and caring that it made the worst time of my life much better. In the end, she helped me get a settlement that was better than I had originally counted on. I've had a great many issues and problems with my ex in the almost 10 months since my divorce. Erin has stepped up and assisted me with getting them settled. (Yes, for a fee!) Having Erin and her staff on my team made me confident and comfortable throughout the process and continuing. If you're looking for a lawyer in Will County, I can't say any more than I did above - hire Erin! You won't be sorry!!! Not many people can say they 'love' their divorce lawyer, but I sure can and do as often as I get the chance. Thanks Erin, Jessica and Arielle!!!!

Would not recommend

I will start by saying Erin is very passive & does not seem to have her clients best interest in mind.I hired Erin to handle my contested divorce, she NEVER provided me with a status unless I asked her & even then she answered my questions in a "round about" way. During negotiations, my ex's attorn...ey was allowed to control what was requested, Erin sat back & never challenged anything. despite my protests not only did did my ex receive more than half the martial assets, but to this day I only see my child the equivalent of 1x week even though I am a good parent. In addition to paying my CS, the alimony entered was not communicated correctly to the court, so I continued to pay alimony even after dates stated in the agreement. I had to go to the courthouse & create the petition to have it withdrawn. I now am going back to court to create a new agreement & "clean up" the mess from the original divorce agreement.

One of the BEST!

I retained Erin in late 2009 to guide me through a very bitter divorce. This was one of the most frustrated experiences of my life. Erin was there for me every step of the way and kept me well informed throughout the process. In the early stages, you may find yourself consumed and overwhelmed at t...imes. I remember sending Erin an email on a Saturday morning sharing some of my thoughts and within an hour or so I received a response back with advice. This remained the standard throughout my entire experience with Erin. Erin was very careful to set fair expectations and did not make any promises she could not live up to. She was the voice of reason at times I felt like throwing reason out the window. Her billing methodology and fees were some of the most reasonable in Will County. My ex spent 1.5 times what I spent and from my perspective received inferior service. My divorce is final, I have ample fathering time with my boys, and I can concentrate on the more positive things in life thanks to Erin’s help. Erin is supported by two wonderful young ladies in her office, Jessica and Arielle who demonstrate the highest level of professionalism. There is always someone available and you will never go for any period of time wondering and waiting for a response. I recommend Erin and her staff to anyone seeking a fair, caring, honest family law attorney.
