EXCEPTIONAL attorney in WILL COUNTY
Erin is the most understanding, compassionate attorney I have ever dealt with. Due to the nature of my job, I know a lot of attorneys, and Erin is by far the most professional attorney I have ever met. She is not only intelligent; she is by far the most detail oriented attorney I know of. The end result of my case was ruled in my favor, but even if it hadn't gone in my favor, I would most definitely recommend Erin. She is very attentive, knows the law, and will make time to talk through everything with you. Her staff is absolutely exceptional as well. I can't say enough good things about Erin and her staff.

Excellent Family Attorney
I can’t imagine a divorce ever being a good experience, but Erin worked hard to make a bad situation as good as possible. Her practice is small and specialized, so she can give her clients the attention they deserve. Erin was always quick to respond to email and phone questions. She knows her stuff too. When it was time to make a decision, she would thoroughly explain all of my options and the possible consequences of each. Her sound recommendations were made based on her knowledge of the law, the judge assigned and her “legal opponent.” By hiring Erin and her firm, I believe I got the best result possible. I certainly hope never to have to use her services again, but I would certainly recommend her.

Very impressive!!
If you are looking for a detailed oriented go getter, look no further. Erin reviewed my agreement that was written up by my soon to be ex- wife's attorney. In short, she read every word of my agreement with passion to help me. She read through the standard language that I was expecting to pass through. She is so detailed orientated that she not only found wordage of great concern, she also found grammar and punctuation problems. If you are looking for an attorney to get things done right, set up a consultation with Erin and see for yourself. I believe you will be as impressed as I was. My only wish is that she practiced other areas of law. Thanks again Erin! Jimmy

Hard work achieves good results
If you need an attorney who is hard working, attractive, tall and maintains herself in court with poise and dignity while still conveying a sense of conviction, it would be wise to contact Erin Webster O'Sullivan. Erin is committed to providing first rate legal service to her clients. She will stay in touch through emails and will return phone calls. She is kind and attentive to a client's needs. Further, she will be honest in guiding her client through the legal process. She also expects her clients to work with her while she handles the finer points of a legal case. Erin is patient, willing to compromise to achieve a good result. Best of all, Erin follows through on her commitments. Without fail, she will ask for client approval of every single step in fulfilling her obligations as an attorney to reach a successful conclusion in each case. Another satisfied client, Daniel

Erin was very considerate of the special circumstances in my case. A few other lawyers I spoke with just wanted to give me standard answers,didn't really want to go "the extra mile." Erin did,and it made a huge difference in a difficult time. She is a pro!!
Posted by Chris S. | April 25, 2013
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 number 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!!!!

EWO got it done
Erin was the only good part of my difficult divorce. She is a dynamite attorney - pragmatic, no nonsense and efficient working through the key issues. She listened to my concerns, understood my priorities and made sure my best interests were addressed. Some other attorneys seem work with their own agenda and don't take the time to listen. Erin helped me navigate through a tough time in my life and I can't thank her enough.

I highly recommend Erin
Having no idea where to start with my divorce, I really needed someone that I could trust and rely on and Erin exceeded those expectations. She took the time to understand my situation and was able to guide me through the process and the steps that I needed take. Throughout the process, she and her staff were professional, thourough, and very responsive and I would highly recommend her to anyone.

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 times. 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.

Great lawyer
Ms. O'Sullivan handled my divorce case for me. She and her staff were very attentive to the specifics of my situation. They were reachable in many different ways and were always quick to get back to me with an informative answer. On the final court date, Ms. O'Sullivan was a very calming force in what can be and was a very stressful time.

Excellent Family Attorney
Erin was recommended to me by a respected, former county judge. My ex wife hired an attorney to raise alimony after 2 ½ years being divorced. Her attorney was also seeking increases to her from my pension. Her attorney was known to be very aggressive and excessive in litigation. She put my mind at ease. Suffice it to say he accomplished none of his / her goals. Erin did some excellent research on my case. I know many attorneys and have engaged two divorce attorneys previously. I found them to be unresponsive and very poor at re contacting me on inquires. That was not the case with Erin and her staff. She also refunded hundreds of dollars of my retainer that was not used. That is something I’ve never heard of. I would definitely recommend her

Caring and Compasionate
Erin went above and beyond being an advocate and voice for both myself and my child during a very difficult situation. Erin was able to provide guidance to me and took the time to explain to me the process and potential outcomes a divorice could have on both myself and my child. Erin was extremely timely and compasionate when responsing to all my inquires via phone and email regardless of time of day. She is truly the best of the best in her field and anyone would be lucky to have her representing you.

Highly recommending
Erin was a superior attorney for my divorce case. She is easy to converse with and listened to my concerns with child custody and financial issues with compassion and concern. She breaks things down to common language, did not overwhelm me (in an already over the top stressful situation) with a lot of "legal-ese" talk. While I had not had past experience with long-term legal issues-I am continually told that attorneys never return calls or take forever to get back to you--not this office. My calls or emails were returned the same day by Erin herself or one of her assiatants if Erin was not available for some reason. The "front line" service speaks volumes for her business as well. Her office staff is outstanding and very professional. Their attention to detail is outstanding and they too are very prompt when returning calls or answering emails. I was never made to feel like I was "bothering them" by calling (sometimes several times a day!) They were always able to tell me when to expect to hear back from Erin. Erin was very clear and honest up front about what I should and should not expect in terms of this case. I was very pleased with Erin's professionalism and yet she is very friendly and as I mentioned before, easy to talk with. Even when opposing counsel was not repsonding in a timely matter, Erin did not stoop to that level, she was adament about "us" getting things in on time and when required by the court as she knew that would represent our case better to the judge. My parents had to help me financially with the legal fees due to my circumstances, and they too could not say enough about what an outstanding job Erin did in my case. She took the time to answer their questions and never made them feel like they were out of line for asking questions about my case. Erin knows family law. This is an EXCELLENT choice if you are looking for someone to represent you. I hope I don't NEED her services again, but if I ever did....TOP CHOICE for sure!
