smart, caring, effective in court
Phil Tsai helped me with a complex case that included extensive discovery, an elusive respondent, and support needs for me and my six children. He negotiated favorable settlements and carefully crafted a parenting plan and maintenance agreements to meet my family's unique needs. And he won the court's approval. When my former spouse did not honor the court orders, Mr. Tsai filed a contempt motion and won the court's approval again. Despite success in court, my former spouse has not been making good on his obligations. Mr. Tsai is aware my serious financial struggle and has not been pressing me with bills for money I owe. I am so grateful for his help and compassion at this time in my life when I've really needed it.

Philip Tsai represented me in a very difficult spousal support case and attempts to set aside the property division in our Decree of Dissolution, which went to the court of appeals. On all matters, Mr. Tsai did an outstanding job in court and prevailed on my behalf. I was confident in his knowledge and advice on the decisions that had to be made during the course of my case. He is a very hard working attorney, competent, and I feel he had my best interest in mind at all times. I highly endorse this lawyer.

Super Lawyer
Phil Tsai is highly competent. I am a domestic violence survivor and Phil navigated my case with expertise and care. I couldn’t have asked for a better result. His fee is worth every penny. The other reviews here are spot on. I wouldn’t hesitate to recommend him.

Superb legal knowledge and efficient
I can’t thank Phil enough for taking my divorce case. Before I hired Phil, I had interviewed and consulted with numerous attorneys and was glad that Phil was able to represent me on my divorce case where significant assets and child custody are involved. This was a major life changing event for me and every move and turn of events will impact me for many years to come. My ex-wife had hired a local prominent law firm known for its aggressive and intimidating tactics. They serve me with multiple motions and discovery demands. Phil was not intimidated by all that. He was calm, collected and composed. He coached me and guided me through many of the dark days during the divorce with our own interrogatories and legal maneuvers. Phil is thoughtful, compassionate yet can seize the opportunity to be aggressive if it means to achieve our goals. Having an extensive legal experience over the years and connected to his own network of legal experts, CPAs, Psychologists, Phil will prevail in a favorable outcome for your case. I fully trust Phil's judgement and will use him again without hesitation. Phil deserves a 10 star rating! - Deeply grateful in Seattle -

An intelligent but tough divorce attorney with integrity!
If I had to describe Phillip Tsai in a word, it would be (incredible). He took over my case which was extremely flawed and complex. There was a lot of ugliness, mistruths and intimidation from opposing council, which is very frightening when you are battling a dissolution of marriage, with domestic abuse, where a child is involved. Phil sorted through and stuck with facts and integrity. He resolved a very tough case and we came through with the best possible decisions in arbitration, to keep my child safe. Phil was very professional at all times, yet kind, understanding and knowledgeable of the fears and mental stages a parent with a child, where abuse was present experiences. He is also a financial wizard at figures and negotiations with properties, support, financial accounts, etc. and very good at explaining what each means to a client who may not understand complex columns and graphs. He was so real and caring that I worried he may not be aggressive enough, as we were up against a very intimidating and aggressive attorney on the opposing side. Don't let his kindness fool you, Phil is extremely factual and very tough while still holding on to a civil and polite demeanor. I almost felt sorry for the other side when he presented our case. He was fantastic and extremely tough. In the end, nobody ever leaves with everything they want, but I feel we could not have done better, keeping my child safe, working out custody and financially in respect to support and splits of community property. I would strongly recommend obtaining Phillip Tsai or anyone else with Tsai Law Company.

Definitely Recommended
Going through a child custody battle is very frustrating especially when the parents do not see eye to eye on most things. Phil has been the best resource I could have asked for. When I needed to vent he listened, when the process was confusing he spelled it out in a way that was easy to understand but above all he is extremely knowledgeable in his field, well respected by his peers, and most importantly for me, he managed to finalize my case in the most favorable way possible for my daughter and I.

Kind, Caring, Compassionate
My experience was more than I could ask for. In a time that is very difficult I found the staff and attorney to be top notch. The caring, compassion, kindness and knowledge helped ease the situation. I would recommend Philip Tsai for your legal needs.

Impressive service
I don't even know where to begin. Philip's character truly shines through in his service. I was able to fully trust his judgments and could tell he had my best interests in mind at all times. He even tried to get the case to settle early multiple times. In the end though, the outcome was strongly in my favor thanks to his preparation and strategy. I was very impressed by his quick intellect. My favorite attribute however is the human aspect. As I was walking into this situation blind with no knowledge in what to do, his guidance was key and at all times, I felt he was extremely respectful and willing to hear me out on how I wanted the case handled. I would wholeheartedly recommend Philip to anyone in need of a family law attorney. He will deliver top notch results and you will know you hired the best.

Trust Phil 100%. Excellent job. Many thanks!
Phil did excellent job for me going through the divorce, finalizing parenting plan through a mediator at the end. He is highly experienced, hardworking and TALANTED lawyer. He knows what he is doing, pay attention to details. When I hire Phil I felt very safe, without stress at all and felt that I am in a good hands. I will definitely recommend Phil.

Calm, focused, and effective
I would highly recommend Phil Tsai, for anyone, going through a divorce, one of the most difficult passages of life, for both spouses. I went through this passage after a long term marriage, with deep emotional conflicts, and I was very glad that I hired Phil Tsai to represent me. He is not only a smart, experienced lawyer, but he is an excellent communicator who understands not only the legal process but also comprehends the human interactions during the process. My case had hard complex issues, with high emotions and high assets. He listened carefully and assessed the complexities with a human ear, and not just a legal pad. Although there must be other good, competent divorce attorneys in the area, I think Phil Tsai is probably exceptional in that he helped me, as his client, to understand and navigate the “inherently adversarial process” and to keep focus on what is really important and come out with a legal/financial fair outcome. Without his calm legal guidance, I would have fallen off the cliff. I believe that Phil Tsai’s intelligent legal steps and steadfast, strong negotiations were very effective. He is a respectful attorney, and despite his busy practice, he always returned my calls and emails in a timely manner. In the end, you have to trust your attorney to work hard and do the best to represent you, and that’s what Phil Tsai did. He helped me get through the legal maze, protect my position when things got rough, then kept me in focus, and arrived at a fair settlement. I would recommend Phil Tsai to anyone, any age, without reservations. He is an excellent attorney with a smart brain and a good heart. -January 2015

Experience working with Phil on Divorcing a Microsoft Executive
Phil did an excellent job guiding me through a 20 month Divorce proceeding. Even though Mediation failed and we had to go through JDR with a Judge it worked in my favor. I had to endure a longer Divorce which of course encures more lawyer fees but in the end it was all worth it. We were going to settle with 5 years of spousal support after 22 years of Marriage but going through JDR bumped the Spousal support to 7 years. I had never hired a Lawyer before so this was my first experience and I really think Phil is an excellent advocate especially as it relates to your interests and well being. I would highly recommend the Tsai firm.

My saviour!
Phil has helped me with ongoing litigation that my ex-husband has put me through and continues to do for the past three years since our divorce has been finalized. Phil has won several of our cases thanks to his expertise and knowledge of the law. I could not be more pleased with our decision to drop my old attorney, and make the financial sacrifice it took to hire Phil, and recoup the money lost through my ex-husband not financially supporting our son appropriately. Now, I am receiving the child support that I had missed out on for over a year. Thank you Phil!

Smart + respected = positive results
I've been represented by Phil Tsai since 2006. I trust him 100% and he's never steered me wrong in all of these years. We've been to court, mediation and depositions and each time his calm manner, knowledge of the law and advice to me has resulted in the best outcome every time -- My daughter is thriving and happy due to the equal time she's been able to spend with me since she was 2 years old (she'll be 12 soon). She may never realize it but i will always be grateful to Phil Tsai for helping my daughter to remain at the school she started at & for the incredibly strong, close relationship she & I are able to have due to our time together -- It's likely these positive outcomes would never have been possible without Phil sticking with me every step of the way.

Phil Tsai: Seattle's best listener in family law, also tough, well-prepared and responsive
Phil was my family law attorney for about a 12 month period in 2012-2013. We had to enter temporary orders with King County Court, as well as finalize the divorce through a mediator at the end. Throughout the year, Phil was incredibly professional, always prepared for our meetings and conf. calls and our two very critical meetings with the judge and mediator and excellent at talking me through the various steps in the process. He strikes an important balance between doing what is best for his clients and knowing what will result in the best outcome from a legal perspective. I would not hesitate to recommend him.

Successful divorce
I started this process with very little knowledge of divorce law. He guided me step by step the whole way and made sure I had the best possible outcome. I can't thank him enough for everything he did for me. He helped me understand everything, held my hand when I was scared and supported me the whole way. I am very happy with the settlement and spousal support I received. Thank you Phil for everything.

Philip Tsai is an excellent attorney. I do not hesitate recommending him to anyone going through a divorce or custody proceeding. I found Mr. Tsai to be honest and trustworthy. He kept me informed about my case and was very knowledgeable about family law. Most importantly, Mr. Tsai was able to obtain the most favorable settlement possible for me, which I was very worried about. I am glad I was able to find him to represent me.

Got Results
Phil Tsai is sharp, focused, well-organized, highly ethical, and effective in court. Like a good quarterback, he helped to win a favorable settlement. Before meeting Mr. Tsai, I had hired and fired two other family law attorneys who were older and more experienced. They were resting on their laurels, and following procedures, but doing no better than I might have done on my own. Phil Tsai made a difference, and fast. Within two weeks I had temporary support coming in, and twice the amount that the other lawyers thought was possible. Mr. Tsai will not waste your money or your time.
