Your Peace of Mind Starts Here

At Warren Major LLP, we believe that stellar legal representation involves not only delivering positive results but also reducing client anxiety during the legal process.

Compassionate, expert legaL representation

Warren Major LLP is a highly regarded, top-rated Marin County family law firm. We are proud to be able to say that most of our new clients come to us through referral from past clients and other attorneys within the San Francisco Bay Area community. That’s because we truly care about our clients, earn their trust, and advocate strongly on their behalf.

We believe that aggressive litigation tactics only serve to increase attorney fees and cause lasting damage to already frayed relationships, particularly when children are involved. Instead of relying on contentious litigation, we resolve nearly all of our cases, even very complex ones, with an amicable settlement. We are proponents of alternative dispute resolution, such as mediation, if it is the best strategy for our client. If a legal hearing is necessary, however, we will fiercely and skillfully represent our client in family court.

Our Practice areas

We specialize in all family law matters, serving clients primarily in Marin, Sonoma, and San Francisco Counties.

Divorce

The decision to end your marriage is only the beginning of many legal steps you must take.

High Asset Divorce

If you are seeking a divorce in a high asset, high net worth financial situation, you need the representation of a skilled divorce attorney.

Divorce Mediation

When their desire to divorce is mutual, many couples choose divorce mediation over litigation.

Collaborative Divorce

In a California collaborative divorce, you and your soon-to-be former spouse or domestic partner negotiate the terms of your divorce or separation together with professional help

Child Custody

When parents separate or divorce, they must establish a plan for child custody and visitation. The plan will detail how they will share access to their children.

Child Support

If you have decided to seek a divorce or separate from a co-parent, you should seek the solid counsel of a family law attorney at Warren Major LLP.

Spousal Support

The divorce attorneys at Warren Major LLP can help you obtain the right amount of spousal support to take care of your needs today, as well as into the future.

Property Division

California is a Community Property state. In a divorce, all separate property remains the property of the owning spouse, and community property is divided equally.
