Services
If you die before making a will, the "descent and distribution" laws of the state in which you reside become your will. Although descent and distribution laws vary from state to state, they generally result in the surviving spouse's financial activities being restricted where there are children of the marriage and no efforts being made to save on estate taxes.
Diana is an amazing attorney, always there when you need her and always keeps you posted on what's happening with your case. She actually came to the hospital when my business partner was diagnosed with stage 4 cancer to help us get everything taken care of that needed to be completed prior to him passing.

After 35 years of marriage ending in a divorce I appreciated the professional advice provided during the Mediation process that ensured that my rights and needs were represented. Each correspondence was addressed promptly and thoroughly. I have all ready referred Diana K. Zilko, Attorney at Law to a friend who unfortunately is also going through a divorce. Sound legal advice can be a comfort during a challenging time.

I have known Diana since 2016. She handled my Divorce and did my Estate Planning and Trust.
Diana is by far the best attorney I’ve ever dealt with. I was faced with a difficult divorce case as the other side was antagonistic. I am very impressed by her integrity, and professional knowledge concerning family law.

My friend recommended Diana Z. About 4 years ago. I didn't know of any Family Law Attorneys in Rancho Cucamonga area and my friend has been her client for many years along with other family members. I met up with Diana just after I was served divorce papers from.my ex. And within less than a month Diana had a court date set up. The court date was fast & the ex did not check his mail until a week & half before the court date. Although it took nearly 3 years to finalize because ex had medical issues, Diana is wonderful, guiding me throughout the process. I was satisfied with the finalized

My husband and I worked with Diana to complete a family trust. She is extremely knowledgeable in this area for the state of California, and she was quick to say if one of our questions was outside her scope, for example questions about legislation in other states. Diana explained all the details clearly and succinctly. She was also very patient, responsive and flexible. She was willing to make a few changes to our documents based on a discussion we had just before signing.
We were super satisfied with Diana's work. It's such an important step in order to keep your estate out of probate. I would

Diana helped me through a very difficult legal issue and I could not be happier with my decision to hire her. She kept me informed along the way and was always quick to respond to my calls. While you may not want to call an attorney, you won't regret your call to Diana.

We found Diana via my husband's work. We had 2 zoom call meetings, which were very helpful, Diana answered all of our questions and some we didn't even know to ask.
Our signing meeting went very well, speedy and having everything notarized and completed in half an hour.
Diana is very personable and we very much enjoyed meeting with her.
We highly recommend her services!

Diana is my first stop whenever I have questions regarding Family Law and Estate Planning. She listened patiently and asked the important questions in order to get to bottom of my issue. Diana is a conscientious, diligent, and dedicated attorney that I highly recommended to anyone looking for an attorney in this field. She treated me like family and made me feel comfortable right away when I initially consulted with her.

Several years ago I used Diana to write up a prenuptial agreement. The agreement was so ironclad my fiancee's attorney advised her against signing it. She signed, and eight years later decided to go splitsville. The divorce was quick and painless because there was nothing to contest (no kids involved) as it was all spelled out in the agreement. Diana's thoroughness and dedication to her client (me) saved me many sleepless nights and aggravation. Paul McCartney should have used her!

Just want to shout out Diana for a very professional, very friendly experience we had. She was very patient, understanding, made sure all of our questions and concerns were addressed. She met with us initially, drafted up our documents quickly, sent them to us for review, spoke with us for a lengthy conversation translating legal speak. We could not be more pleased with the outcome. Thank you Diana! I wouldn't hesitate to recommend you to others!

Is very unclear in her communication and doesn't explain what's going on, charges too much and never replies to her phone calls/emails. She also has a very dingy office that looks like it belongs to another century and smells like mold!

I got into a very bad car accident 2 years ago, and luckily at the time, I was living in brea. I found Diana from all the great yelp reviews, and I am glad I did. She was fantastic. Any questions I had, and concerns I needed addressed, she would help me. She made me feel comfortable at such a rough time in my life. I pray I don't end up in another car accident, but if I do, she will be the person I go to. I will also refer her to friends and family, because these types of situations are never easy, and she took all the stress away from me. I would hire her again and again!

I went to Diana to take care of my estate planning. I had done some basic research, but was still unfamiliar with exactly what needed to be done and didn't really understand all the parts of it. She was able to explain our options so that we understood and could choose the right setup for us. Once she got the information and our input as to what we wanted, she wrote up the documents for us.

Upon receiving our feedback, she amended the items we discussed and got us all set up and explained all the next steps we would need to take on our own.

Our experience with Diana was excellent, she

I am so thankful to Diana for her legal and personal advise when I consulted with her. I thought I had done the most I can to research and do everything on my own before I came to her. I was so glad that I went and met with her! Her advise help me tremendously! I have recommended her to my family and friends already!

I'm not going to make this very long but we've had a terrible experience with this attorney. There were too many incidents that made us lead to believe that she wasn't working for our interest and/or was incompetent. We've had to fix many clerical errors as well. Many important direct questions were left unanswered unless pressed.

All in all, we ended up doing tons of research on our own and felt that if we weren't very careful or self-informed, we would end up with serious legal disadvantages. We really weren't sure which side she was on. For those reasons I
