I have been practicing law since 1989, virtually all of which has been devoted to family law, first as a litigator, then mediation, and beginning in 2004, collaboration. My current practice is comprised of all three models. I believe it is important for every client to understand each of the three available paths to resolving their divorce, and then pick the model that best suits their particular situation. My preference is to resolve issues outside of court. When clients and their attorneys make a commitment to do that, which is the hallmark of a collaborative divorce case, the clients are best able to maintain control over their lives and the outcome of the issues in their divorce. While collaborative divorce can be exceedingly challenging, I have found it to be the most rewarding work I have done as a family law attorney. I grew up in the East Bay and received my undergraduate degree from UC Berkeley and law degree from Golden Gate University. I currently live in Oakland with my wife and daughter. Len Weiler and I have been law partners since 1999. Our office has been in San Ramon since 1990. I have been an active member (treasurer and steering committee currently) of our local collaborative practice group (now Collaborative Practice East Bay) and a member of The International Academy of Collaborative Professionals since 2004. I have been a member of our three local bar associations, Contra Costa County, Alameda County, and Eastern Alameda County, for the last 19 years. I have served on the Board of The Eastern Alameda County Bar Association since 1994 and am a Past President (1999). I also joined the Board at my daughter’s school in May 2007 and have very much enjoyed the challenges that presents.

Emily M. De Falla
General Comments

Compassion, communication, and authenticity are as important to my work as are my legal skills. I never forget that my work is in service to my clients and I strive to bring respect and empathy to all my interactions.

I believe that families don’t belong in court. That’s why I devote my practice to helping couples resolve disputes peacefully, with respect and dignity.

During my decades in court handling contested custody, support, and property division cases, I saw first-hand how divorce litigation can take a great toll on a family. Fear and anger make it hard for normally reasonable people to compromise. The children are under great stress. Even when one side “wins,” both sides come away emotionally damaged.

My search for alternatives to litigation led me to Mediation and Collaborative Practice. I am grateful to have these real tools to help families reduce the tension and conflict of a divorce.

What Clients Say

I would highly recommend Emily De Falla for family law matters and collaborative practice divorce. Not only is she strong and outspoken when necessary, but she is also remarkably insightful and perceptive – two qualities which are particularly important during a collaborative practice divorce. Her communication was clear, calm and kind as she guided me through the complexities of the divorce process. You will be well-represented with Emily De Falla as your lawyer.” –B.D

I have practiced family law exclusively since 2005 because I find great meaning working directly with my clients on matters that deeply affect their lives. Having been divorced myself, I know how important it is to have a caring, competent, and effective attorney in a family law matter. Whether I’m coaching my client behind the scenes, negotiating a settlement in a meeting or mediation, or litigating in court, I take my responsibilities seriously knowing that the results I achieve will have long-lasting effects. I take pleasure in applying my expertise to resolve legal matters so that my clients can move on with their lives. While I can and do litigate with the best of them, I prefer keeping my clients out of court so they can direct their own futures, instead of having a judge direct it for them.

I am a Certified Family Law Specialist with the State Bar of California and am active in the following organizations: Association of Certified Family Law Specialists; Alameda County Family Law Association; and the Alameda County, Contra Costa County, and California Bar Association Family Law Sections. I also volunteer in the Alameda County Superior Court as a Family Law Settlement Referee helping to settle thorny cases that are on the eve of trial. I received my undergraduate degree at UC Berkeley and my law degree at UC Davis.

She believes that clients are better prepared to make decisions when they have all available information. She has enjoyed working in multi-disciplinary teams and knows that divorce can be one of the most emotionally and financially stressful experiences for clients. For that reason, she believes finding the right professional for each client is critical.

She graduated from Wesleyan University and worked in Advertising for several years before she attended Santa Clara University School of Law.

General Comments

We begin marriages and domestic partnerships with the hopes and intentions of having a relationship that will bring friendship, love, and satisfaction to our lives and the lives of the children we have or may have together. When we discover that the bonds we’ve formed have, for whatever reason, come apart, we are confronted with emotions ranging from shock, denial, and anger to relief, guilt, and resolve. Dissolving our union requires we act on many levels including grieving the loss of what we had hoped for and of what we had as a family and, at the same time, putting on our business hats and thinking about our and our family’s financial and emotional well-being in the future. We can feel angry that someone whom we trusted has made a decision that may mean a loss in the time we spend with our kids and a loss in our standard of living. We may be surprised by or feel ashamed of our own feelings and the behaviors that accompany them. There is nothing easy about the process of dissolving a marriage or domestic partnership. Melanie works with her clients to help them cope with what is by its nature a very challenging transition, to discover and become clear about what is most important to them and why and how to articulate this to their spouse or partner in a clear, non-provocative way. She assists her clients to be clear thinkers when they are triggered by emotional reactions, to learn to be prepared for what they might hear during negotiations, and anticipate when they might react emotionally to a topic or their partner’s behaviors. Melanie assists her clients to think through what their children’s needs are and how best to support them during this transition and after. Melanie received her Bachelor of Arts from the University of California, Berkeley, and her Masters of Science in Clinical Child and School Psychology from California State University East Bay. She has been licensed as a Marriage and Family therapist since 1993. She brings years of experience working with families in transition to Collaborative Law and mediation, and is described by clients and collaborative peers alike as being simultaneously empathic, compassionate, clear, and direct. Melanie offers services in divorce coaching, custody mediation, co-parent counseling, and crisis intervention for couples who are trying to save their marriages or partnerships.

I am a licensed Marriage and Family Therapist with nearly 30 years of experience. I provide collaborative coaching and mediation services as well as therapy to individuals, couples, families, adolescents, and their parents. My aim is to assist clients to find healthy solutions to individual, marital, and family issues. I have a Master’s Degree in Clinical Psychology from John F. Kennedy University, a Doctorate Degree in Clinical Psychology from Saybrook Institute (formerly Humanistic Psychology Institute), and post-graduate training in child custody evaluation, mediation, and the fundamentals and principles of collaborative divorce. As a divorce coach, I find that couples divorcing often believe that intractable problems can only be solved by divorce. Many clients believe that getting a divorce will allow the family to move into a better place. Divorce can be a step toward resolution but not necessarily a resolution. A positive transition through the difficult process of divorce can lay the foundation for better and more satisfying relationships in the future. In my experience as a coach, I find that the present predicts the future. Couples often go through the divorce process with the same unresolved issues they have during the marriage and often worse. If their style of communication does not change, these issues will continue not only during the divorce process, but long into the future. Therefore the need to improve the quality of communication between the couple is critical and especially if children are involved. In fact, studies have shown that families, where parents are not divorced but live with high conflict, have more child-adjustment problems than the divorced families with less conflict. Thus, the same factors that led to the divorce likely have had a negative impact on children by the time the divorce actually occurs. It is for these reasons I believe the value of improving communication in order to craft agreements that take into account the best interests of the whole family. Collaborative divorce aids in restructuring the nuclear family. The aim is to create a family that functions better than the previous family structure. Collaboration is consensus-building that is based on a solution that works for everyone, a win/win. The collaborative process holds much promise for a successful outcome to a difficult life transition.

I have been a Licensed Marriage and Family Therapist since 1998. I graduated from John F. Kennedy University in 1996. As well as being a member of the Collaborative Practice of the East Bay, I am also an Honorary Member of the Contra Costa County Bar Association, Family Law Section.

Prior to working as a Collaborative Divorce Coach, I worked as a court appointed Child Custody Evaluator and Non-Confidential Recommending Mediator for Contra Costa County and Alameda County Superior Courts. I also worked as a Family Court Services Mediator for Contra Costa County Superior Court. While I no longer provide these type of services, I am grateful for the experience these roles provided me in understanding and supporting individuals and their families going through divorce.

I currently focus my practice on working in more collaborative divorce processes including, but not limited to, Collaborative Divorce. In Collaborative Divorce, I typically work either as a Divorce Coach or as a Child Specialist. I also provide confidential custody mediation, individual therapy for clients going through the divorce process, and co-parenting counseling for parents seeking to transition from the couple relationship to the co-parenting relationship post-divorce.

Going through a divorce, even if it is your choice, is likely to be one of the most difficult events you will experience. If you have children, it can be particularly painful as you know that they will also need to make changes in their lives that they did not choose. It is therefore so important that, as you navigate this, your whole family gets appropriate support and guidance in order to move through this in the healthiest manner possible. That is the ultimate goal of Collaborative Divorce. It is not for everyone, but it certainly is important to consider, if you think it may be for you.

Commitment, Respect, Integrity. These words hold important meaning to Emily, and she measures herself against these words in her work with collaborative practice clients. The collaborative divorce process requires a commitment from every member of the team to treat each other, and the process itself, with integrity and respect. Emily believes that this commitment offers an opportunity to move through a divorce without the devastation often associated with the traditional court-based model of divorce, and offers the potential for relational growth and healing. Emily assists clients to bring their best selves forward to make agreements that will serve the needs of the entire family. In this time of pain and confusion, she helps clients to manage complex emotions, identify needs and goals, and communicate in a clear and productive manner. She believes that the interdisciplinary team approach to collaborative practice offers clients a support system that optimizes the family’s ability to move through this difficult transition and to create a new family system (when a couple has children), to allow for growth and healing in the future. After the divorce, Emily remains available to work with her clients, on an as-needed basis, to assist in further post-divorce transitions.

Emily has worked as a collaborative divorce coach and parenting mediator since 2004. Her work as a collaborative divorce coach is informed by her experience of working for sixteen years as a family law paralegal. Her legal experience, combined with her experience and training as a mental health professional, give her a unique perspective in working with collaborative divorce clients, ending a marriage or domestic partnership.

Emily received her BA from the University of California, Santa Cruz, and her MA in Clinical Psychology from John F. Kennedy University. She has trained extensively in Powerful Non-Defensive Communication and conflict resolution and mediation. She has taught collaborative divorce skills to the collaborative community in California, Texas, England, and Germany. She is a licensed Marriage and Family Therapist in private practice in Oakland, California.

Emily is a founding member of Collaborative Practice East Bay, and is a member of Collaborative Practice San Francisco. She is also a member of the International Association of Collaborative Professionals, Collaborative Practice California, and the California Association of Marriage and Family Therapists.

For couples going through a divorce, the process can be extremely difficult, and assessing the various settlement options, without the requisite financial expertise can be daunting. Since many of the decisions made about the division of assets are difficult, if not impossible to change once the divorce is final, it is imperative to be fully informed of the short and long-term consequences of potential settlement alternatives, so that the family has the best chance of protecting its financial stability going forward. At Topel & DiStasi Wealth Management, with our vast experience in personal financial planning, our team can apply the same rigorous approach we use for our comprehensive planning process, to your divorce case, in order to provide you and your family with the confidence to move past this difficult and uncertain time, and get on with your lives.

Planning for the future is an essential part of every divorce settlement. The divorce will soon be your past but the decisions made during the process will have a significant impact on the future of you and your family. As a Certified Divorce Financial Analyst® and Certified Financial Planner®, I am able to help create a picture of the potential short and long-term consequences of possible settlements BEFORE you make a commitment that could be difficult or impossible to change. I have extensive experience working on collaborative and mediated cases since 2000. I continue to participate in collaborative groups around the Bay Area and speak about the collaborative process and the role of the financial professional. It has been my experience that financial issues are often cloaked in fear and uncertainty. My personal desire is to take away this fear and replace it with positive and productive action by providing information and perspective that is often hard to see while trying to cope with the difficult and emotional issues in a divorce.
