Use this checklist before deadlines scatter
FMLA certification work is easy to lose when the request, forms, reminders, and final designation notice live in different places. This checklist gives HR a simple order of operations for documenting the case without turning the page into legal advice.
Step 1: Eligibility and rights notice
When an employee requests leave or the employer learns leave may be for an FMLA-qualifying reason, track the eligibility notice and rights and responsibilities notice together.
Deadline to track
The employer generally provides the eligibility notice within 5 business days after the initial request or after learning the leave may be FMLA-qualifying.
What to document
Record whether the employee is eligible, the notice date, the delivery method, the leave year used for entitlement tracking, and whether certification is required.
Step 2: Medical certification request
If certification is required, document exactly when HR requested it and what the employee was asked to provide.
Deadline to track
Employees must receive at least 15 calendar days after the employer's request to provide medical certification. Track this due date as a case task, not only as a note.
What to document
Save the request date, the form or certification type requested, the due date, the delivery method, and any extension reason based on diligent good-faith efforts.
Step 3: Incomplete or insufficient certification
If the certification is incomplete or insufficient, avoid vague reminders. Tell the employee in writing what information is needed to make the certification complete and sufficient.
Deadline to track
Employers generally must allow at least 7 calendar days to cure the deficiency, unless that timing is not practicable under the circumstances despite diligent good-faith efforts.
What to document
Record the written cure notice, the specific missing or unclear information, the cure deadline, each follow-up attempt, and any employee explanation for delay.
Step 4: Designation notice
After HR has enough information to determine whether the leave qualifies, the case should move to a clear designation decision rather than staying open indefinitely.
Deadline to track
The designation notice is generally due within 5 business days after the employer has enough information to determine whether leave is FMLA-qualifying.
What to document
Record whether the leave is designated as FMLA leave, the amount of leave counted if known, any fitness-for-duty requirement, and the final delivery date.
Operational checklist for each case
A repeatable case file should make the next action obvious to HR and make the history readable later.
How AI SoloHR supports the workflow
AI SoloHR helps small HR teams keep FMLA deadlines, tasks, notes, documents, and reviewed communications in one case workspace. The software supports tracking and drafting, but HR still reviews decisions and should involve qualified counsel for legal questions.
Source and review boundary
This checklist is based on public U.S. Department of Labor FMLA materials reviewed for 2026 operations. It is educational content for HR workflow planning and is not legal advice.
How this guide fits the real workflow
A guide page is most useful when HR already knows the issue but needs a clearer operating pattern. The goal is not just to define the topic. It is to make the next step, the right record, and the workflow sequence easier to see before something slips.
- Use the guide to standardize what should be documented
- Share the workflow with managers or teammates who need the same context
- Move into a template or a case workflow when the issue becomes active work
