Executive Summary
SMS marketing for legal practices sits at the intersection of advertising ethics, TCPA consent, and A2P 10DLC registration. Intake reminders and case-status logistics differ from solicitation texts promoting consultations. Firms must capture prior express written consent for marketing, register 10DLC Brands/Campaigns for local long codes, and avoid sensitive case details in message bodies. Bar advertising rules may impose additional constraints—coordinate with ethics counsel.
Short answer: Use separate consent and Campaigns for marketing vs client-service texts. Register 10DLC (or another approved sender path). Keep SMS content non-sensitive. Ethics + TCPA + carrier rules all apply.

Worked example: a family law firm's client texting
A family law firm wants to text consultation reminders to new inquiries and case updates to retained clients. It registers one brand under the firm's legal entity and a Mixed campaign covering appointment reminders and service updates, with no promotional content. Consent is captured on the web intake form and in the engagement letter, using language approved by the firm's ethics counsel.
The firm does not text prospective clients who have not contacted it, which avoids both TCPA marketing rules and state bar solicitation concerns, and it never buys leads. Case update templates say only that a document is ready or a hearing date has changed and direct the client to the secure portal for details, so no confidential information is exposed on a lock screen.
