A recently reported combination between two prominent Arizona-based law firms is set to reshape the state’s business legal landscape. According to reports, Fennemore and Gallagher & Kennedy have agreed to merge, with the transaction scheduled to take effect on December 1, 2026, and the combined organization operating under the Fennemore name. The reported deal would create one of the largest business law platforms in the state, with a substantially expanded footprint in Phoenix, the broader Southwest, and a New Mexico presence through a Santa Fe office.
For most readers, a law-firm merger sounds like inside-baseball news. But for Arizona business owners, executives, investors, and in-house counsel, a combination of this size can raise very real, very practical legal questions — especially if you are (or were) a client of either firm, or if your company is contemplating a similar corporate combination of your own. At Desert Valley Law, PLLC, we field these questions from Arizona business owners regularly, and this article is meant as a plain-spoken guide.
What Happened
According to public reporting, two established Arizona law firms have agreed to combine into a single organization that will operate under one name beginning in late 2026. The reported combined entity will house roughly 300 legal professionals in Phoenix and more than 800 across all offices, with expanded capabilities described as including natural resources, environmental, water, litigation, and general business law. The reports also indicate the surviving firm will absorb a Santa Fe, New Mexico office and integrate technology initiatives across the combined platform.
While this is a business transaction — not an incident of alleged harm — mergers of this size regularly create downstream legal issues for clients, counterparties, employees, and other stakeholders. Understanding those issues in advance is the best way to protect your interests.
Who May Be Liable
In any large professional-services or corporate combination, several categories of parties could potentially face exposure if things go wrong:
- The combining entities themselves. If a merged firm allegedly fails to honor pre-existing client engagement terms, mishandles conflicts of interest, or breaches confidentiality during integration, it may be liable to affected clients.
- Individual professionals or officers. Attorneys, directors, and officers who owe fiduciary duties could be individually exposed if they allegedly place personal or firm interests ahead of client obligations.
- Successor organizations. Under successor liability principles, a surviving entity in a merger generally steps into the shoes of its predecessors and may be responsible for pre-merger obligations.
- Third-party vendors or technology providers. If integration of case management systems, data platforms, or AI tools allegedly compromises client data, those vendors could be liable alongside the firm.
None of these theories should be read as an accusation against the parties to the reported transaction. They simply describe the categories of risk any large combination can create.
Legal Theories That May Apply
When a business combination goes sideways for a client, counterparty, or stakeholder, several legal theories commonly come into play:
- Breach of contract. Engagement letters, service agreements, and vendor contracts survive a merger. A party may have a claim if the surviving entity allegedly fails to perform.
- Breach of fiduciary duty. Attorneys, corporate officers, and directors owe fiduciary duties that do not evaporate at closing. Alleged self-dealing or divided loyalty during integration can support a claim.
- Professional negligence (legal malpractice). If integration disruptions allegedly cause missed deadlines, blown statutes of limitation, or mishandled matters, an affected client may have a malpractice claim.
- Conflict-of-interest violations. When two firms combine, previously separate client relationships may collide. Arizona Rules of Professional Conduct require careful screening; alleged failures can create liability.
- Tortious interference. Competitors, departing partners, or third parties who allegedly interfere with existing client relationships during a transition may face claims.
- Shareholder or partner disputes. Partners or equity holders who allege they were misled about deal terms, valuations, or governance rights may have derivative or direct claims.
- Data-privacy and confidentiality claims. If confidential client information is allegedly exposed during system integration, statutory and common-law privacy claims can arise.
Damages Victims May Recover
Depending on the theory and the facts, an affected client or stakeholder may be able to recover several categories of damages:
- Direct economic losses. Money paid for services not properly rendered, or losses caused by an alleged breach.
- Consequential damages. Downstream business losses that flow foreseeably from the alleged breach or negligence.
- Lost business opportunities. Deals that fell through or profits that evaporated because of alleged mishandling.
- Disgorgement of fees. In fiduciary breach cases, courts may order return of fees paid.
- Punitive damages. In Arizona, punitive damages may be available where a defendant is shown to have acted with an “evil mind” — a high bar reserved for egregious conduct.
- Attorneys’ fees and costs. Under A.R.S. § 12-341.01, a prevailing party in a contested action arising out of contract may be awarded reasonable attorneys’ fees at the court’s discretion.
Evidence That Strengthens a Case
If you believe you have been harmed in connection with a business combination — whether involving a law firm, a professional service provider, or your own corporate transaction — the following evidence tends to strengthen a claim:
- Signed engagement letters, retainer agreements, and any amendments
- Written communications (emails, letters, portal messages) with the firm or counterparty
- Billing records and invoices, before and after the transaction
- Internal memos or notices sent to clients about the combination
- Documentation of conflicts checks, waivers, or disclosures you received (or did not receive)
- Evidence of specific harm: missed deadlines, adverse rulings, lost deals, disclosed confidential information
- Witness statements from other clients, former employees, or industry participants
- Regulatory filings, bar disciplinary records, or public complaints
- Expert reports from professional-responsibility, corporate-governance, or valuation experts
What to Do Next
If you are a client, partner, vendor, or counterparty potentially affected by a large business or professional-firm combination, a few conservative steps can protect your position:
- Preserve everything. Save engagement letters, emails, invoices, and any notices you receive about the transition. Do not delete communications.
- Document harm as it occurs. Keep a dated log of missed deadlines, communication breakdowns, or other concerns.
- Read notices carefully. Merger notices sometimes include deemed-consent language for conflicts or fee changes. You are not required to sign anything without review.
- Do not speak with opposing insurers or counsel alone. Anything you say can be used to limit your recovery.
- Mind the deadlines. Arizona’s statute of limitations for legal malpractice is generally two years from discovery, and breach-of-contract limits vary. Waiting can extinguish otherwise valid claims.
- Get an independent legal review. A neutral outside attorney can assess whether your engagement, contract, or governance rights have been compromised.

Frequently Asked Questions
Can I sue if my law firm merges and drops my case?
Possibly. If a firm terminates your representation without reasonable notice, fails to protect your interests during transition, or allegedly causes you measurable harm, you may have a claim for breach of contract or professional negligence. Arizona ethical rules require attorneys to take reasonable steps to protect a client’s interests when withdrawing.
What happens to my engagement letter after a law firm merger?
As a general rule, the surviving firm inherits the predecessor’s engagement obligations under successor-liability principles. That said, the merged firm may propose new terms or ask you to sign an updated engagement letter. You are not required to accept new terms without independent review.
How do conflicts of interest work when two firms combine?
When firms merge, previously unrelated client matters may suddenly sit under one roof, creating potential conflicts. Under Arizona’s Rules of Professional Conduct, the combined firm must run conflicts checks and may need written waivers or ethical screens. Alleged failures in this process can support a disqualification motion or a professional-responsibility claim.
How long do I have to bring a legal malpractice claim in Arizona?
Arizona generally applies a two-year statute of limitations to legal malpractice claims, typically running from the date the client discovered — or reasonably should have discovered — the alleged harm. Deadlines can be complicated by ongoing representation and the discovery rule, so it is important to consult counsel promptly.
What if my confidential business information was exposed during a merger integration?
If confidential information was allegedly exposed through system integration, data migration, or inadequate screening, you may have claims for breach of confidentiality, breach of fiduciary duty, or statutory privacy violations. Documenting exactly what was disclosed and to whom is essential.
Can partners or shareholders challenge a merger they disagree with?
In many cases, yes. Partners, members, or shareholders who allege they were misled about deal terms, denied required approvals, or subjected to unfair valuation may pursue direct or derivative claims. Governing documents and Arizona’s business-entity statutes shape what remedies are available.
Do I need a new attorney if my current firm is being acquired?
Not necessarily, but it is reasonable to get an independent second opinion — especially for high-stakes matters. Look at whether new conflicts have arisen, whether your primary contact will remain involved, and whether fee structures are changing. You always retain the right to choose your own counsel.
What damages can an Arizona business recover in a merger-related dispute?
Depending on the theory, recoverable damages may include direct economic losses, consequential business damages, disgorgement of fees, and in egregious cases, punitive damages. Under A.R.S. § 12-341.01, prevailing parties in certain contract actions may also recover reasonable attorneys’ fees at the court’s discretion.
