Practice areas
  1. Divorce and separation

  2. Child custody

  3. Family

  4. Child support
    I can assist with establishment of child support orders and modification, enforcement and/or termination of existing support orders.

I am a family law attorney practicing in Scottsdale, Arizona and the surrounding areas. I began my legal career as an Assistant Attorney General at the Arizona Attorney General's Office. In this capacity, I provided representation to the Department of Economic Security, Division of Child Support Enforcement, and appeared in several hundred child support related court hearings. 

Upon resigning from the Attorney General's Office, I started my own family law practice in Scottsdale, Arizona.  In 2012, I partnered with Ronee Korbin Steiner to form Korbin Steiner & Marquis.  In 2015, Ms. Korbin-Steiner was appointed to the Maricopa County Superior Court bench, and I maintained my practice in family law. Areas that I have experience in include: dissolution of marriage, legal separation, child support, paternity, parenting time, legal decision-making (formerly "custody"), spousal maintenance, modifications and enforcement of existing orders, relocation, orders of protection, and injunctions against harassment.

On a personal note, I am the mother of six children ranging in age from 2-15. I am a football fanatic and I love to travel, read and spend time with my wonderful husband. I also believe in the importance of giving my time to those who are less fortunate.

Divorce and child custody
Divorce is a painful and difficult experience where children are involved . I met Rebecca a couple of years ago. I watched her do an exceptional job with my sisters case. I Thank you for thinking about all angles of the situation. While my case was different , and the problems were solved. I ultimately longed for the comfort of Rebecca and her newer assistant , Shelly.

Experienced, professional, attentive and hard working
I was a client of Ms Rebecca Marquis of Marquis law firm. Ms. Marquis fought hard for me in a professional, efficient, proficient and caring manner. She always responded in a timely manner explaining everything in detail. Ms. Marquis exhibited compassion and a willingness to listen to my concerns. Ms Marquis was more than my attorney, she became a friend. I would highly recommend Ms. Marquis without reservation.

The best divorce/child custody attorney
Rebecca did an exceptional job from the very start of our consultation all the way to the dissolution of my marriage. We had many obstacles and challenges and she was very quick to overcome them and kept me at ease. She always promptly responded to any issues, concerns and questions I had. She helped me tremendously to protect my children when I needed the legal authority and I’ll forever be grateful for that. She is very pleasant to work with. I highly recommend Rebecca, you will be in good hands.

Rebecca has been my attorney for a decade, give or take a little. I COULD NOT RECOMMEND ANYONE MORE!!! She's absolutely amazing! My case has become very complex of the last year, and she has been better than any expectations I had. Thanks Rebecca!

Rebecca is amazing
We hired Rebecca after using a different family law attorney who we were not happy with. We were recommended to Rebecca by a friend who happened to be one of the best prosecuting attorneys in the state. We knew if this attorney was recommending her, she had to be exceptional. Seconds in to our consultation with her, we knew we made the right decision. Rebecca is the most compassionate, dedicated, hard working professional we have ever met. She truly cared about us and our case. She is beyond smart when it comes to family law (sad that we actually have to say that but so many family law attorneys seem to need help in this area). Rebecca stayed in continuous contact with us, explaining every step of this process. Our case was a contentious one, that included multiple court appearances and litigation, and Rebecca was a superstar. She is a tenacious trial attorney. She has the ability to be an amazing lawyer both in and out of court. She is ethical and does not "fight dirty". Rebecca was the reason our case turned out the way it did. She also fought for attorney fees in our case, and in her usual style, was successful. The family law process is a scary one. Rebecca constantly calmed our nerves, answered every question we ever had, and made us feel like we were her only clients (believe me, we were not). She was available to us at all hours, and was a true ally to us. I have never met a person who is so motivated, genuine, intelligent, and caring as Rebecca Marquis. I would (and have) highly recommend her to anyone. Perhaps most importantly, Rebecca actually cares about her clients. We went in hiring Rebecca as our lawyer, and ended our journey with not only the best lawyer that we could have ever imagined, but a new friend as well. Five stars are not enough.

The Attorney Lawyers Use
I am a licensed attorney who does a variety of things, and while I am knowledgeable enough to represent myself in my divorce, I hired Rebecca Marquis. It was the best decision of my life. It reminded me that when you need legal help, choose a lawyer who focuses in one area, and who has a reputation for being the best. I was fortunate to have been referred to her by another attorney that used her in her divorce. The testimonials don't lie- she is the divorce attorney in Phoenix to go to when you need someone to fight for you.

If ever an attorney deserved 6 stars it's Rebecca
I've been working with Rebecca for over a year now and I've been blown away by her skill, responsiveness, intellect, and temperament. First I will say that my case isn't typical and I doubt the process would be as dragged-out as much as mine has been because of the particulars in the case. She has an excellent feel and temperermant that goes a long way to getting both parties to an agreeable solution. In my opinion there are too many attorneys who look to fan the flames of their clients' emotions in what is almost always a powderkeg of hostility. Rebecca is the opposite; she will work for ways to avoid court unless the opposing counsel/party are being unreasonable. In that case she can be an absolute bulldog. In the courtroom she is poised but aggressive when need be. She's very responsive and a pleasure to work with. I really can not say enough. I met with and vetted a half dozen attorneys in the Valley, but I wish I'd saved the time. I've been 110% satisfied with my decision to have her in my corner.

Rebecca is our warrior. She is absolutely the best choice you could ever make for your family.
I can't speak highly enough about Rebecca's office but of course, especially Rebecca herself. Rebecca was our warrior. Very honestly, every time we saw and spoke with her, we felt safe and protected. I imagine that sounds weird but it's so very true. We cannot thank her enough for fighting for us and ensuring that we got what was fair and sane. I wish that I had Rebecca with me the first time but we're positive that we'll be sticking with her for any future needs. We got absolutely everything we asked the Judge for in our case and I'm positive this has everything to do with how brutally honest and straightforward Rebecca was with us. It's easy to allow emotions to dictate what you want to bring before a Judge and Rebecca pulled NO PUNCHES with us. She was not afraid to tell us what we needed to let go of and how to stay focused on our goals. We had just heaps and heaps of things we wanted to bring before the Judge and Rebecca taught us how to get focused and trim everything down to exactly what we needed to ensure we could get what was right for our child. That said, she was more than happy to edit, re-dit, reword, add or subtract over and over until we were perfectly satisfied. She's an amazing listener, very well organized, and one of the sharpest people I've ever encountered. I just can't say enough about her. She is on her game. Not only is she answering her emails to us even on a Sunday night but we received our Judgement from her at something like 4 in the morning. We're almost convinced that Rebecca is a robot. ;) Their billing seems to be extremely reasonable and ethical. I haven't received my final bill however so far they don't seem to be charging me for every nanosecond spent thinking about my case. Overall, you are doing your family a great service by meeting Rebecca Marquis. You will not regret it it whatsoever.

The Lawyer I should have used years ago
Rebecca is wonderful, always attentive to my case and response time for emails and phone calls is beyond the call of any lawyer, she always kept me in the loop and didn't try to gouge me on my fees like most lawyers. she handels her self profesionaly and knows more than most lawyers I know, I only wish I had used her 8 years ago in my divorce to start with rather than waste my money on a crap lawyer that I had before. I would absoulutly recomend her to anyone , any time. She got me exactly whatI asked for and then some.

We know we made the right chice!
Rebecca, Now that we have completed the modification, it has allowed us to take a step back and reflect on the process. First and foremost, thank you. We cannot stop talking about you and how you genuinely made sure that our interest was best served. These modifications are a stressful process that in many ways does not accurately reflect a system of fairness. We could not be more pleased with your advice, approach and the way you fought for us. Throughout the process you made sure that we understood the potential outcome. Whether in our favor or not. You actually brought a sense of calm to us, having equipped us with information. We wanted to make sure that you knew we feel that we had an advantage by retaining Korbin Steiner and Marquis. We will encourage anyone we know that is dealing with family law issues to contact your firm first! Again, we can't thank you enough for your excellent work.

Money well spent
I first went to see rebecca on the advise of a friend ( who is a lawyer, but not family Law), who works in the same building as I do. I explained to Rebecca, my situation, how tight my finances were, and she agreed to take me on as a client. She said I could do this myself, and save me some money. But not knowing the legal system here, I asked if she could do the paper work for me, which she did.... I needed to get my child support modified, as one of my sons turned 18 last April, again Rebecca ask why i had taken so long to file the modification, I told her I didnt have the funds to do so.... To cut a long story short, we agreed a fee for her time and services, I paid the money, and Rebecca went to work. She filed all the paperwork found a process server in Texas, as my ex lives out of state, and we waited for our court date. That date came, and Rebecca was good enough to get my child support almost cut in half, from what I was paying. All I can say to anyone else who is looking for an excellent lawyer, who practises family law, then you should use Rebecca, she knows her stuff, I was kept well informed through the whole ordeal, she is friendly, well mannered, and an absolute wonder to work with. When my child support is due to end in 2014, I have already told Rebecca I want to use her for this too, So i need to start saving!.

Rebecca Marquis
Rebecca was very helpful and successful in the modification of my parenting plan. She is very knowledgeable and unbiased...she will tell you like it is. She was very considerate and always available and quick to respond. While any child custody/parenting related case is stressful, Rebecca helped me feel more at ease about the whole drama of the situation. She is an excellent Lawyer and I would recommend her to anyone needing legal assistance; and I would definitely use her services again, if needed.

Divorce/Child Custody
Rebecca by far is the best attorney I have ever come across. She handled my divorce & child custody case. She is extremely knowledgeable at what she does. She was very compassionate towards my children & my situation, very honest & never once, did Rebecca not take the time to answer any questions I had no matter how big or small they were. She was there for me every step of the way throughout my trial of almost 9 months. She is w/out a doubt, persistent, hardworking & is really honestly, great at what she does. I would w/out a doubt, refer her to my family, friends or anyone who is in need of an excellent attorney. W/out Rebecca I don't know what I would have done. I highly recommend her! -Suzette

Great Personal Service
I had a very positive experience working with Rebecca. I found that she was very timely with her work, very personalized with her service and always ready to find answers quickly. She also kept things as efficient as possible so it was cost effective to work with her, and did not move forward on ay correspondence without my consent. I would work with her again, and also recommend her services.

Wonderful attorney and person
I have used Rebecca for several court proceedings and she has been great everytime. She is awesome and has a great knowledge of family law. She not only helped me with my case but she also cared and made me feel more like family than an attorney/client relationship. She is great in all aspects and I would highly recommend her.

No need to search any further
When I filed for divorce I moved out of the marital residence and filed on my own. The "other party" immediately got an attorney which began threatening me with all types of allogations. After interviewing several attorneys that basically said I was in a bad position I was turned onto Rebecca. Rebecca was the answer to all my prayers. She represented me throughout my divorce proceedings totally making the other party squirm as she hammered away. She also helped me with getting custody of my son which everyone told me wasnt going to be possible. I have spent the last year working with Rebecca and she has always been up front with her advice and has delivered the results. Anyone that is looking for an attorney should definately consider Rebecca. She will deliver results. She will not only be a hard working attorney but her passion is absolutely amazing.
