How to Apply for Mental Health Leave and Obtain Required Documentation Under FMLA, ADA, and U.S. Law

Mental health is now widely recognized as a critical component of overall well-being. In the United States, federal laws such as the Family and Medical Leave Act (FMLA) and the Americans with Disabilities Act (ADA) provide clear protections for employees and students who need time away due to psychological health challenges. However, to take advantage of these rights, you must understand the correct procedures, required medical documentation, and your employer or school’s expectations. This in-depth guide will walk you through how to apply for mental health leave under FMLA and ADA, what proof you need, and how Havellum—the professional provider of fast, authentic, and verifiable medical certificates—can support you every step of the way.
We’ll link 6 authoritative Havellum resources for further reading and practical guidance.1. Why Mental Health Leave Matters—and Is Protected by Law
Conditions such as depression, anxiety, PTSD, and burnout can be as disabling as physical illness. U.S. law recognizes this reality and provides mechanisms for you to request protected leave or accommodations, ensuring you can recover without risking your job or academic status.
Your rights are safeguarded primarily under two statutes:
- FMLA (Family and Medical Leave Act) – Offers up to 12 weeks of job-protected, unpaid leave for serious health conditions, including mental health.
- ADA (Americans with Disabilities Act) – Requires employers and schools to provide reasonable accommodations for qualifying mental health conditions.
For a comprehensive breakdown of how these laws work, read Understanding the FMLA: Navigating Leave Documentation and Lawful Medical Notes.
2. When and How to Request Mental Health Leave Under FMLA
Who Is Eligible?
To qualify for FMLA leave:
- You must work for a covered employer (50+ employees, public agencies, or schools).
- You must have worked at least 1,250 hours in the past 12 months.
- Your mental health condition must be considered a "serious health condition" by a medical provider.
What Is a "Serious Health Condition"?
Mental health conditions such as major depression, severe anxiety, bipolar disorder, or PTSD typically qualify if they:
- Require inpatient care or continuing treatment by a healthcare provider.
- Substantially limit your ability to perform work or academic duties.
How to Apply
- Notify your employer/school as soon as possible, preferably in writing.
- Request FMLA leave for your mental health condition; you do not have to disclose your diagnosis but must provide enough information to allow the employer to determine FMLA eligibility.
- Submit a medical certificate from a licensed U.S. provider (e.g., psychiatrist, psychologist, or primary care doctor).
For an in-depth guide on the process and documentation, see Mental Health and Leave: How to Use Psychological Medical Certificates for Paid Leave.
3. ADA: Requesting Reasonable Accommodation for Mental Health
The ADA protects employees and students with qualifying mental health conditions by requiring reasonable accommodations (unless this creates undue hardship for the employer/school).
Examples of ADA accommodations:
- Flexible work or class schedules
- Remote work/study options
- Modified duties or extended deadlines
- Temporary leave of absence
How to Apply
- Submit a written request for accommodation to your HR or disability office.
- Include a medical certificate from a licensed provider stating you have a condition that substantially limits one or more major life activities. The certificate should specify the recommended accommodation, but detailed diagnosis can remain confidential.

4. What Should a Mental Health Medical Certificate Include?
A legally valid psychological medical certificate should contain:
- Your full name and date of birth
- Date of evaluation and provider’s credentials
- General statement confirming a serious mental health condition (diagnosis is optional)
- Recommendation for leave or accommodation (including recommended duration)
- Provider’s name, license number, and contact information
- Official signature and/or digital verification code
Privacy note: The certificate does NOT need to include the specific diagnosis or highly sensitive details. Employers and schools are required to keep all medical information confidential.

Key steps:
- Obtain a certificate from a licensed psychologist or psychiatrist.
- Notify your DSO (Designated School Official) or academic advisor as early as possible.
