About William

Learn William’s areas of practice.

I have represented the construction industry for more than 27 years.  Most of my work is in litigation and arbitration where I represent developers, contractors, subcontractors and suppliers in court or before an arbitrator.  Although I usually serve as an attorney I also serve as a mediator or arbitrator.  I regularly contribute to legeisliation on behalf of the construction industry, including as a member of the legal advisory committees of AGC and ASA and through my memberships on numerous construction organizations. I was the founding president of Region Builders, Inc.  and a founding board member of Real Estate and Construction Networking.  I have been appointed an El Dorado County Superior Court Judge Pro Tem.  I chaired the State of California committee of construction attorney who revised the construction laws found in Civil Code 8000 to 9566.  I was the first attorney to draft and published the construction claim forms to meet the requirement of these new laws.  I am committed to responding to my clients promptly, almost always within an hour after the call or e-mail - unless I am in court or arbitration.

I have been working with the Porter Law group for over 15 years on many different business matters. Bill and his group have work with us on issues concerning construction, personnel and reviewing and writing complicated contracts. Bill’s counsel has helped us set up limited liability companies for real estate purchases and their management. I am always impressed with The Porter Law Firm’s expedient approach and follow through to complete our needs. We continue to use the Porter Law Group and recommend them to anyone that has a need for sound legal counsel.

Great Attorney with High Level of Knowledge, Integrity, and Honesty
Bill has been my attorney for almost ten years now and has helped my firm with contract negotiations, corporate formations, and other business transactions. He is extremely reliable, helpful, and delivers great quality work and legal counsel. Many acquaintances of mine within the business community that are construction contractors think very highly of him for the same reasons as well as his deep knowledge of construction law. I highly recommend Bill for counsel.
