Experienced and Made a Very Hard Process Easier
I had a very difficult divorce that took a great deal of time to get through. Yvonne and her staff were an amazing support through the entire process. Yvonne was sensitive, supportive, strong and extremely knowledgeable, fair and balanced. She fought for my situation and my children with unwavering strength. I always felt like she was levelheaded when at times when I may not have been. She guided me through a painful time and we ended up with an extremely successful outcome. I highly recommend Yvonne and her firm.

Helen Yvonne Seeley
I recently went through an otherwise very stressful divorce and court trial. I am a practicing physician and my ex a housewife for 17 years. I have three children. I was at a distinctly disadvantageous position to begin with. My divorce lasted for 2 years from the time of filling. My ex and her boyfriend hired 2 teams of very aggressive attorneys from Southern California and San Francisco making the case very complicated, over litigated and stressful. I felt I was helpless until I met Yvonne Seeley and her team of associates and assistants. With professionalism, super knowledge of California family law, and super experience as a trial lawyer, I was able to more than survive the ordeal, ending with a fair and satisfactory trial result, and having my interest maximally protected. Ms. Seeley and her team, taking my interest in heart and practice, knowing what is relevant and what is not, have turned a very complicated, overwhelming and over litigated case into a relatively simple one, backed up by legally sound case laws, theories, reasoning and argument. In the process, she convincingly pointed out the obstreperous, dishonest and greedy nature of the other party. Ms. Yvonne Seeley and her team has walked extra miles to help me. I went through the darkness of a long tunnel that appeared without hope of reaching the other end, then rediscover meaning of life, and establish confidence in the fairness of the California court. This good lawyer makes a huge difference in my life. I recommend Ms. Seeley without any reservation. I whole heartedly thank Ms. Seeley and her team.

Helen Yvonne Seeley: Top notch counsel
Ms. Seeley's counsel in my marriage dissolution was invaluable. She helped me understand the dissolution case process, and helped me to manage my own expectations with respect to timing of case events. She's the consummate attorney in the sense that she's the strongest advocate for her clients. In family law cases where things can get muddied by a bit of emotion, she keeps things real and in perspective. As a paralegal, I was able to prepare the bulk of paperwork myself, but without Ms. Seeley's keen eye to some details, and recommendations as to alternatives -- in specific related to division of property and spousal support, the case might still be pending judgment. I was pleased to receive the desired outcome with the court in a reasonable amount of time. The courts might be a bit slow, but the team at Seeley & Madigan couldn't have been more responsive. Questions answered right away, and proposed solutions offered quickly. I wouldn't hesitate to recommend Helen Yvonne Seeley and the team at Seeley & Madigan. If ever I need family law counsel again, Ms. Seeley would be the first attorney i'd contact.

Excellent in so many ways.
can't say enough about Ms. Seeley. I went through a high conflict divorce and there continues to be battles. She handles everything like an ultimate. Many people understand the law but at the end of the day, especially when going through a difficult time, service becomes of paramount importance. Ms. Seeley is honest, responsible, professional, responsive and proactive. And, on top of that, I found her experience to be a huge asset. Why is experience so important? Because experienced attorneys know the personalities of Judges and other attorneys. They know when to go to court and when to settle out of court. They also know 3rd parties such as custody evaluators, vocational assessors, mediators and others who become an important part of the process. I recommend her without hesitation.

Great Service
I had moved from the USA back to Australia by the time my divorce proceedings began. I really didn't have any idea where to start dealing with the courts in California. Helen "Yvonne" sorted, handled, and expedited the whole process for me and it went very smoothly. Documents were emailed to me where possible, hard copies sent as necessary, and my questions answered promptly. I was even advised on where I could find a US notary here in Perth Australia. Great service! I really felt looked after during the whole process.

Review for Helen Yvonne Seeley
Yvonne Seeley represented my sister in a very emotional and debilitating divorce. I was very much involved from start to finish because of the emotional state of my sister and was aware of all steps taken by Ms. Seeley to ensure she was fairly and honestly represented. There was no need on my part for any concern . Family law is one of the most difficult areas of the law, but Ms Seeley was caring and forthcoming throughout this nightmare, and handled my sister's case with integrity, expertise, trustworthiness and just the right amount of aggressiveness. In our opinion, she is the absolute best, and we would recommend her highly to anyone.

Thoughtful and detailed attorney
I worked with Yvonne as an associate family law attorney in her firm. She's very thorough and her years of experience and attention to detail will make any client feel secure and confident in her work and representation. She's firm with her opponents but also has great working relationships with others in the community. Her litigation skills are top notch.

Great Family Law Attorney
Just like you, I was looking on the internet for an attorney and ran across the Seeley and Madigan website. I scheduled a consultation and knew right away that Seeley & Madigan was right for me. Yvonne (Helen) and Kimberly listened, really listened, to me and together we worked on a plan and then fully executed my legal separation. Ending a marriage is never easy, however, Yvonne or Kimberly was always available, offered tissues when I needed them, and kept me on task when I wanted to just throw in the towel. I got the settlement I wanted. Thank you Seeley & Madigan.

Exemplary Lawyer and Law Firm‎‎
Seeley & Madigan was referred to me by a close friend and I hired them to represent me in my recent divorce case. The firm was a pleasure to work with through a difficult time and they made me and my interests number one from beginning to end. Seeley & Madigan explained my position clearly and gave honest, straightforward advice as we moved through the process. In the end my case was resolved in my favor. I am thankful for their professionalism, clarity, attention to detail, and kindness. I would use and recommend their services again without hesitation.‎
