Child Custody
We are committed to representing every client with integrity, dedication, and with the understanding that you are trusting us to resolve your divorce or family law matter as if you were a member of our family.
Litigation of child custody rights and visitation (parenting time) is difficult and emotionally trying. Child custody litigation can arise in dissolution of a marriage or domestic partnerships. In most custody cases, parents must either come to an arrangement that is reasonable for both their children and the parents, or an arrangement will be made by the court. Our goal is to negotiate the best arrangement out of court but we are fully prepared to present the most effective argument should litigation be necessary.

Decisions made during child custody cases will have significant impact on your children. In California, courts look at the best interests of the child when making child custody determinations.Our priority is protecting the interest of the children involved in this difficult process while helping parents make the most informed decisions.

Children suffer during a custody battle over time spent with each parent and decision-making authority (e.g., which school to attend). We make every effort to assure that children do not suffer and that our clients have time with their children. We do not lose sight of our clients and their families' needs and advocate for both.

We represent clients in their child custody proceedings in San Francisco County, San Mateo County, Marin County, Alameda County, and Contra Costa County.
Divorce
We are committed to representing every client with integrity, dedication, and with the understanding that you are trusting us to resolve your divorce or family law matter as if you were a member of our family.
Divorce (dissolution of marriage) can be stressful and traumatic. We understand the decision to divorce is difficult but also must be handled efficiently, but carefully.

We handle a full range of matters related to divorce with the commitment to securing fair resolutions to our clients. In cases of divorce, a range of simple and complex issues will surface. These issues can include: child custody, child support, spousal support, distribution of property, marital estates, post-divorce disputes, modification of orders, and appeals. It is important to have fully prepared and competent legal representation when such issues arise.

As divorce lawyers, we help our clients through this difficult time, reducing conflict and helping our clients make the best legal choices available to them during the dissolution process. Our priority is to ensure our clients know exactly what to expect in this difficult process. Knowing what to expect can lessen the stress and provide clarity when critical decisions must be made. We explain the different process options specific to each case and provide recommendations appropriate for each case and client. We are thoughtful in protecting marital and parental rights, ensuring each matter is given appropriate consideration and attention.

In developing legal strategy, we are mindful of cost and seek to minimize expensive legal processes, but never to the detriment of our clients' cases. We maintain close communication concerning legal expenses.
Family
We are committed to representing every client with integrity, dedication, and with the understanding that you are trusting us to resolve your divorce or family law matter as if you were a member of our family.
