What does Stephen Moses handle at Bay Legal?
Stephen’s work runs along two tracks that meet in the middle. The first is construction law: claims and disputes, contracting for owners and builders, mechanics liens and payment bond claims, bid protests, defect claims, and contractor licensing questions. The second is technology and business: licensing and distribution agreements, technology transfer, privacy compliance, commercial contracts, and trade secret and non-compete litigation. Both tracks run transactional and litigation work, so the lawyer who drafts the agreement is the one who tries the case when it fails. Stephen also handles real estate matters where a construction question sits underneath a property question.
What kinds of construction disputes does Stephen handle?
Stephen has handled construction claims since 1998, for owners, homeowners, general contractors, subcontractors, suppliers, and design professionals. Typical matters include payment disputes on unfinished or contested work, mechanics lien and payment bond claims under California Civil Code section 8000 et seq., construction and design defect claims governed by the Right to Repair Act at Civil Code section 895 et seq., and bid protests on public work.
He also works the licensing side. The Contractors State License Law at Business and Professions Code section 7000 et seq. governs who may contract in California, and section 7031 bars an unlicensed contractor from suing for compensation at all. Home improvement contracts carry their own form and disclosure requirements under section 7159, and a contract that misses them can be unenforceable against the homeowner. Stephen drafts and negotiates the agreements these disputes come from: prime contracts, subcontracts, home improvement contracts, change-order procedures, and scope and payment terms. He has also served as in-house counsel to a heavy civil and engineering contractor, writing the company’s standard forms and supporting public-contract bidding. See contractor licensing issues for more.
What technology and licensing work does Stephen handle?
Stephen has served as corporate counsel inside technology companies as well as outside counsel to them. That work covers inbound and outbound software licensing, distribution agreements including VAR and OEM arrangements, end-user and SaaS agreements, technology transfer, product development agreements, registration of intellectual property rights, privacy compliance, and technology diligence on transactions. Most recently he negotiated SaaS agreements with local governments for an enterprise artificial intelligence provider.
California privacy obligations for most businesses handling consumer data run through the Consumer Privacy Act at Civil Code section 1798.100 et seq., as amended by the Privacy Rights Act. Contract terms on data handling, security, and breach notice are usually where that obligation actually lands.
Trade secret and non-compete litigation
Stephen has served as lead trial counsel in trade secret misappropriation and restrictive-covenant cases in state and federal court in California and New York. California claims arise under the Uniform Trade Secrets Act at Civil Code section 3426 et seq., and federal claims under the Defend Trade Secrets Act of 2016. Employee non-competes are a separate question in this state. Business and Professions Code section 16600 voids most agreements that restrain someone from practicing a lawful profession, and amendments effective in 2024 extended that rule to agreements signed out of state. Confidentiality and non-disclosure agreements remain enforceable when they are drafted properly. He works both sides: enforcing rights for the company whose information walked out the door, and defending the employee or competitor accused of taking it.
Does Stephen handle real estate matters?
Yes, where the property question has a construction question inside it. Stephen represents buyers and sellers in disclosure disputes — claims that a seller failed to disclose a known material condition. California requires most residential sellers to deliver a Real Estate Transfer Disclosure Statement under Civil Code section 1102 et seq., and disputes usually turn on drainage, foundation movement, water intrusion, mold, or unpermitted work.
Whether a defect was knowable, when it appeared, and what it costs to correct is a construction question before it is a disclosure question. Stephen has also handled commercial lease and tenant-improvement disputes, including allowance and completion claims at the close of a build-out.
Who does Stephen represent?
- General contractors, subcontractors, and suppliers pursuing or defending payment and lien claims
- Owners, developers, and homeowners in disputes over unfinished, defective, or overbilled work
- Design professionals, including engineers and architects, in defect litigation
- Technology and product companies on licensing, distribution, privacy, and trade secret matters
- Business owners who need commercial agreements drafted, negotiated, or enforced
- Buyers and sellers in real estate disclosure and purchase-contract disputes
When does a construction or real estate dispute go to mediation first?
Often before anyone files anything. Most California Association of Realtors purchase agreements contain a mediation clause, and a party who skips mediation can lose the right to recover attorney fees even after winning. Many construction contracts contain a similar step. Stephen holds a mediation certificate from the Straus Institute for Dispute Resolution and has mediated litigated construction, technology, and business disputes since 2012, which shapes how he prepares a case for that first session.
| Mediation | Arbitration | Litigation | |
|---|---|---|---|
| Who decides | The parties; the mediator has no authority to rule | A private arbitrator or panel | A judge or jury |
| Binding? | Only if the parties sign a settlement | Usually binding, with narrow appeal rights | Binding, subject to appeal |
| Typical timeline | Weeks to a few months | Several months to a year | One to three years |
| Relative cost | Lowest | Middle; arbitrator fees can be significant | Highest |
| Common trigger | A contract clause requires it before filing | A contract clause requires it instead of court | No clause applies, or a party refuses to comply |
How does Stephen work a new matter?
- Intake and conflicts check. Bay Legal’s intake team gathers the basic facts and clears conflicts before the consultation.
- Document review. Contracts, disclosures, inspection reports, invoices, change orders, and correspondence get read before any strategy discussion.
- Claim and defense assessment. Stephen identifies which claims are available, which deadlines apply, and what the realistic range of outcomes looks like.
- Pre-litigation resolution. A demand letter, negotiation, or contractual mediation resolves many matters without a filing, and often preserves a fee-recovery right.
- Filing and litigation. When resolution fails, the matter proceeds in the appropriate California superior court or federal district court.
What matters has Stephen handled?
- Lead trial counsel in a trade secret case involving confidential information contained in construction bids, tried to judgment
- Led the defense of a national logistics company in a trade secret and non-compete case in the U.S. District Court for the Southern District of New York
- Negotiated SaaS agreements with local governments for an enterprise artificial intelligence provider, covering property appraisal applications
- Provided legal support for a major Silicon Valley office remodel, including a tenant-improvement allowance dispute with the landlord at project close
- A construction defect case for a homeowner involving faulty grading and construction, settled against the builder and its subcontractors on the eve of trial in Contra Costa County Superior Court
- Subcontractor payment claims arising from the build-out of a commercial facility in Oakland
- Defense-side construction defect work for engineers, architects, and licensed contractors, including managing the special master process in a subdivision-wide case
- Contract management on a large-scale optical fiber network project, including payment claims and government contract negotiation
Prior results do not guarantee or predict a similar outcome in any other matter. Every case turns on its own facts and the applicable law.

Related Questions
Does Bay Legal represent homeowners against contractors?
Yes. The firm represents homeowners in disputes with general contractors over unfinished work, defective work, and payment demands, and it also represents contractors pursuing payment. Conflicts are screened at intake.
What is a Transfer Disclosure Statement?
It is the form most California residential sellers must give a buyer, disclosing known material conditions of the property. Civil Code section 1102 et seq. governs it. Failing to disclose a known defect can support a claim after closing.
Are non-compete agreements enforceable in California?
Rarely. Business and Professions Code section 16600 voids most contracts that restrain a person from engaging in a lawful profession or trade, with narrow statutory exceptions tied to the sale of a business or ownership interest.
What is a mechanics lien?
It is a recorded claim against real property by a contractor, subcontractor, or supplier who was not paid for work or materials that improved the property. Strict deadlines apply, and missing one can extinguish the lien right.
