How to Write Case Notes in Social Work and Case Management

Last reviewed: October 3, 2026. This article is general information, not legal advice. Record-keeping rules depend on your state, your profession and your agency, so follow your agency's policy and ask your supervisor or counsel when in doubt.

If you're a social worker, case manager or student on placement, you probably write more case notes than anything else, often at the end of a long day. It helps to remember who might read them later: your colleagues, an auditor, a judge, and very possibly the client. Writing with those readers in mind makes notes better and protects everyone.

Short answer: a good case note is a short, dated, factual record of what happened, what you observed, what you did and what comes next. Keep facts separate from your professional assessment, include only what's relevant to the service, write it promptly, and write as if the client and a court could read it, because they may.

Who may read your notes

Case notes feel private, but they rarely stay that way.

• The client. Standard 1.08 of the NASW Code says: "Social workers should provide clients with reasonable access to records concerning the client." Access can be limited only in exceptional circumstances, where there is compelling evidence it would cause serious harm. If your agency is a HIPAA covered entity, the client also has a legal right to inspect and copy most of their records, and the provider generally must act on the request within 30 days.
• Courts and lawyers. Records can be requested in custody cases, child welfare proceedings, criminal cases and lawsuits, including lawsuits against your agency.
• Colleagues and successors. Someone may pick up the case tomorrow with only your notes to go on.
• Auditors and funders. Notes are often how an agency shows a service was delivered and billed correctly.

The legal side: confidentiality, HIPAA and 42 CFR Part 2

HIPAA, where it applies

HIPAA's privacy rules apply to "covered entities": health plans, health care clearinghouses, and health care providers that transmit health information electronically in certain standard transactions. Many clinical and health-related social work settings are covered; some purely social service programs may not be. Ask your agency which rules apply to your records.

Where HIPAA applies, two points matter for note-writing:

• Disclosure in legal proceedings. A covered entity may disclose records in response to a court order, limited to what the order authorizes. A subpoena or discovery request without a court order is not enough on its own: the provider needs satisfactory assurance that the client was notified and had a chance to object, or that a qualified protective order is in place (45 CFR 164.512(e)).
• Psychotherapy notes. HIPAA treats a mental health professional's separately kept notes analyzing the contents of a counseling session as "psychotherapy notes", and the client's right of access does not extend to them (45 CFR 164.524). This is a narrow category. Medication, session times, diagnosis, treatment plans, symptoms and progress summaries are excluded from it (45 CFR 164.501). Ordinary case notes in the client file are part of the regular record.

State privacy laws can be stricter than HIPAA. See when state privacy law supersedes HIPAA.

42 CFR Part 2 for substance use disorder records

If you work in, or receive records from, a federally assisted program that diagnoses, treats or refers people for substance use disorders, a separate and stricter federal rule applies: 42 CFR Part 2. "Federally assisted" is defined broadly and includes things like Medicare participation, federal funding and tax-exempt status (42 CFR 2.12).

The key difference for legal requests is that a subpoena alone does not let you release Part 2 records. The regulation's own example says a person holding the records who receives a subpoena "may not use or disclose the records in response to the subpoena unless a court of competent jurisdiction enters an authorizing order" under Part 2 (42 CFR 2.61). Never respond to a subpoena for these records without checking with your supervisor or legal counsel.

The NASW Code points the same way: social workers should protect client confidentiality during legal proceedings to the extent the law allows, and can ask a court to withdraw or narrow an order, or keep records under seal (Standard 1.07(j)).

How to write a good case note

1. Write it promptly. Notes written the same day are more accurate and more credible. If you must add one later, label it as a late entry with the date you actually wrote it.
2. Start with the basics. Date, time, length and type of contact (home visit, phone, office), who was present, and your name and role.
3. Separate observation from interpretation. Write what you saw and heard, then your professional assessment, clearly labeled. "Client's hands were shaking and she said she had not slept" is an observation. "Client appeared anxious" is an assessment; say what it's based on.
4. Quote when words matter. If a client makes a threat, discloses abuse or states a goal, record their exact words in quotation marks.
5. Record what you did and why. Referrals, information given, risk assessments, safety plans, mandatory reports and consultations with your supervisor.
6. Note the plan. Next steps, who is responsible, and when the next contact is.
7. Include only what's relevant. Leave out gossip, details about third parties that don't affect the service, and opinions about the client's character.
8. Use plain, respectful language. Avoid labels such as "noncompliant" or "manipulative" unless you describe the behavior behind them. A good test: would you be comfortable if the client read this aloud in court?

A quick before and after

• Weak: "Client was uncooperative and in a bad mood. Mom is obviously not coping."
• Better: "Home visit 10:00–10:45 with client (J.) and her mother. J. declined to answer questions about school and left the room twice. Mother said, 'I can't get her to go in the mornings.' Discussed school attendance plan; mother agreed to meet the school counselor on 10/10. Next visit 10/17."

Common mistakes to avoid

• Writing from memory days later without labeling it a late entry.
• Copying and pasting previous notes so that visits look identical.
• Altering or deleting an existing entry instead of adding a dated correction.
• Recording diagnoses you aren't qualified to make, or speculating about third parties.
• Keeping side notes in a personal notebook or phone outside the official record. They can still be requested, and they create privacy risks.
• Releasing records on request without checking consent, HIPAA, Part 2 and agency policy.
