What Is Rule 1.17 in California?
Rule 1.17 lets a lawyer sell a law practice — client files, goodwill, the works — subject to safeguards protecting clients. In one sentence: Rule 1.17 permits the sale of a law practice if clients get proper written notice, an opportunity to hire other counsel, and fees are not increased because of the sale. Both the ABA and California share that baseline. Where they split sharply is on what can be sold and what happens to the seller afterward.
The Core Split: “All or Nothing” vs. Cherry-Picking
The single most tested distinction on California Bar Exam Rule 1.17 questions is this: the ABA lets a lawyer sell just part of a practice; California does not.
| Issue | ABA Model Rule 1.17 | California Rule 1.17 |
|---|---|---|
| Selling only part of the practice | Permitted — a lawyer can sell a specific practice area | Not permitted — must sell the entire practice, or substantially all of it |
| Continuing to practice after selling the whole practice | Seller must cease practicing entirely | Seller may continue practicing elsewhere |
| Client notice required | Yes | Yes |
| Fee increases because of the sale | Prohibited | Prohibited |
Under the ABA rule, a lawyer can cherry-pick: sell only the lucrative personal-injury caseload and keep the modest family-law practice. California forbids that. A California lawyer must sell the entire practice — or substantially all of it — precisely to stop lawyers from selling off the profitable matters while abandoning clients with smaller-value cases to fend for themselves.
The second half of the split runs the opposite direction. The ABA requires a lawyer who sells an entire practice to exit the market — the buyer is paying, in part, for the seller’s absence as a future competitor. California imposes no such exile: a California lawyer can sell the whole practice and later open a new practice, even in the same city, even in the same field.
Why the Two Rules Diverge
The ABA’s cease-practicing requirement protects the buyer’s investment — if you’re paying for someone’s book of business and reputation, you want assurance the seller won’t reappear next door as a competitor. California instead protects clients, particularly the ones with smaller or less profitable matters, from being sorted into “keep” and “sell” piles based on lawyer profit. California is comfortable letting sellers keep working; it isn’t comfortable letting them leave any client group behind.
Worked Example: The Cherry-Picking Trap
Priya runs a solo California practice split between personal-injury cases (often settling for six figures) and family-law matters (steady, but modest hourly fees). A colleague offers to buy just the personal-injury caseload for $400,000, leaving Priya’s family-law clients with her. Under the ABA Model Rule, selling only the personal-injury “practice area” would be fine. Under California’s Rule 1.17, it is not — Priya cannot sell the profitable slice while retaining the rest. The entire practice, or substantially all of it, has to go together, protecting the family-law clients from being an afterthought.
Worked Example: Selling Everything, Then Coming Back
Now suppose Priya instead sells her entire solo practice — every file, every matter, all the goodwill — to another personal-injury firm. She gives every client proper written notice, identifies the buyer, and confirms no client’s fees will increase. The purchase agreement satisfies Rule 1.17’s baseline safeguards, so the sale goes through and Priya retires.
Five years later, Priya decides to reopen a small mediation practice in the same city. Under California’s rule, that’s permitted — nothing in Rule 1.17 required Priya to exit the profession forever. Contrast that with an ABA-jurisdiction lawyer who sells her entire practice under the ABA rule: that lawyer must cease practicing law entirely as a term of the sale. If she reopens a practice nine months later — even in an unrelated field like consumer class actions — she has violated the ABA rule’s structural exit requirement, because the buyer paid for her permanent absence from the market.
The Baseline Safeguards, Regardless of Jurisdiction
Whether ABA or California, every valid practice sale needs:
- Written notice to affected clients, describing the sale and identifying the buyer.
- An opportunity to retain different counsel, rather than being automatically transferred to the buyer.
- No increase in fees attributable to the sale itself.
- A buyer willing and able to undertake the client matters purchased, subject to each client’s consent.
Miss any of these and the sale is defective regardless of whether the “all or nothing” or “cherry-picking” question is even in play.
Common Mistakes on Rule 1.17 Questions
- Selling only the profitable matters in California. This is the single most common trap answer choice — remember California requires substantially all of the practice.
- Assuming a California seller must stop practicing. She doesn’t; only the ABA rule imposes that exit requirement.
- Forgetting the fee-increase prohibition. A sale that quietly raises client fees violates Rule 1.17 regardless of jurisdiction.
- Assuming clients automatically transfer to the buyer. They don’t — clients retain the right to choose other counsel.
- Confusing Rule 1.17 with Rule 5.6. Rule 1.17 governs the voluntary sale transaction; Rule 5.6 separately bars using employment or settlement agreements to buy a lawyer out of future practice.
FAQ
Can a California lawyer sell just the family-law files and keep the personal-injury practice?
No. California’s Rule 1.17 requires the sale to cover the entire practice or substantially all of it — a lawyer cannot split off one practice area for sale while keeping another.
After selling her whole practice, can a California lawyer open a new firm later?
Yes. Unlike the ABA Model Rule, California does not require the seller to cease practicing law. She may resume practice, including in a new city or a different field.
Do clients have to stay with the buyer after a practice sale?
No. Every client must receive written notice of the sale and the opportunity to retain a different lawyer instead of the buyer.
