TL;DR: FMLA for family member care allows you to take up to 12 weeks of unpaid, job-protected leave to care for a spouse, child (under 18, or 18+ if incapable of self-care), or parent with a serious health condition. You can provide physical care, psychological comfort, arrange third-party care, or attend medical appointments. Siblings, grandparents, and in-laws are not covered under federal law unless a state law says otherwise. Here's exactly who qualifies as "family" under FMLA, what "serious health condition" means for them, and how the WH-380-F certification works.
Caring for a sick family member is one of the most common reasons people take FMLA leave — and one of the most confusing. Who actually counts as "family"? What kind of care qualifies? Can you take leave for a parent-in-law who lives in your spare room?
This guide breaks down exactly who FMLA covers, who it leaves out, what "serious health condition" means when it's not you who's sick, and the paperwork (Form WH-380-F) your family member's doctor has to complete before your leave gets approved.
Who Counts as Family Under FMLA?
FMLA defines "family member" narrowly. Federal law recognizes exactly three relationships for family-care leave: spouse, child, and parent. That's it. No siblings, no grandparents, no in-laws — a fact that surprises a lot of people who assume FMLA works like bereavement leave or PTO, where "family" is whoever you say it is.
Spouse
A husband or wife as defined by the law of the state where you were married. This includes:
Opposite-sex and same-sex spouses (recognized in all states since Obergefell v. Hodges)
Common-law marriages, in states that recognize them
Does not include: a boyfriend/girlfriend, fiancé(e), or domestic partner — unless your state independently recognizes the relationship as equivalent to marriage
Child
A son or daughter who is:
"Incapable of self-care" means the adult child needs active assistance with three or more activities of daily living — bathing, dressing, eating, toileting, mobility — or needs supervision because of a cognitive impairment. This is a real medical threshold, not a judgment call you make yourself. The certifying doctor has to document it.
Does not include: an adult child who is capable of self-care, even one with a serious health condition. A 25-year-old going through chemotherapy who can still dress and feed themselves does not qualify you for FMLA leave to care for them — even though the situation is every bit as serious as one that would qualify.
Parent
A biological, adoptive, step, or foster parent — or someone who stood in loco parentis (acted as your parent) when you were a child, even without a legal or biological tie. If an aunt raised you from age six, she likely counts as a "parent" under FMLA.
Does not include: parents-in-law. You cannot take FMLA leave to care for your spouse's mother or father, even if they live with you and you're their primary caregiver. This is one of the most common reasons FMLA requests get denied — employees assume "family" includes the in-laws they've cared for for years, and federal law simply doesn't recognize that relationship.
Who Is Not Covered
Under federal FMLA, none of the following qualify you for family-care leave, no matter how close the relationship or how much care you're providing:
Siblings (brothers, sisters)
Grandparents
Grandchildren
In-laws (mother-in-law, father-in-law, siblings-in-law)
Domestic partners, in most states
Close friends
Adult children who are capable of self-care
State laws may be broader. Some states define "family member" more expansively than federal FMLA does. California's CFRA — its state equivalent to FMLA — is a well-known example of a state law that extends job-protected leave to a wider circle of relationships than the federal statute covers. Coverage details and exact relationship definitions vary by state, so don't assume your state matches federal law either way. Check our California family leave page or your own state's law before ruling out a leave you might actually qualify for under state protections even when federal FMLA says no.
What "Serious Health Condition" Means for a Family Member
FMLA doesn't just require the right relationship — it requires the family member to have a serious health condition, the same legal standard used when you're the one who's sick. The Department of Labor generally defines this as an illness, injury, impairment, or physical or mental condition that involves either:
Inpatient care — an overnight stay in a hospital, hospice, or residential medical care facility, plus any period of incapacity or subsequent treatment connected to it, or
Continuing treatment by a health care provider — which covers several common scenarios:
A period of incapacity of more than three consecutive days, combined with ongoing treatment (two or more visits to a provider, or one visit plus a continuing regimen like prescription medication)
Chronic conditions requiring periodic treatment, even if the person isn't incapacitated between flare-ups — think asthma, diabetes, or epilepsy
Pregnancy, including prenatal care and recovery
Permanent or long-term conditions under a provider's supervision, even without active treatment, such as Alzheimer's or a severe stroke
Any period of absence for multiple treatments for restorative surgery or a condition that would likely cause incapacity of more than three days without treatment
Here's what trips people up: a serious health condition doesn't mean your family member has to be hospitalized or terminally ill. A parent with poorly controlled diabetes who needs a caregiver to manage insulin and attend quarterly specialist visits meets the standard. A spouse recovering from major surgery who needs help for two weeks meets it too. On the other end, a cold, a routine checkup, or a condition that clears up on its own without treatment generally does not.
The health care provider treating your family member — not you, and not your employer — is the one who certifies whether the condition meets this standard. That's exactly what Form WH-380-F is for.
What Kind of Care Qualifies?
FMLA covers more than hands-on medical care. You can take leave to provide any of the following.
Physical Care
Bathing, feeding, dressing
Administering medication
Assisting with mobility
Providing transportation to appointments
Psychological Comfort
Being present to provide emotional support
Sitting with a family member during treatment
Providing reassurance and companionship
This is important: you don't need to be providing skilled nursing care. Your presence and emotional support qualify on their own — you don't have to be the one changing bandages to be "caring for" your parent under FMLA.
Arranging Care
Finding a nursing home or care facility
Interviewing home health aides
Making arrangements for ongoing care after your leave ends
Attending Medical Appointments
Doctor visits, treatments, therapy sessions
Consultations about the family member's condition
Meetings with healthcare providers about care plans
How to Request FMLA for Family Care
Notify your employer. Give 30 days' notice if the need is foreseeable — for example, a scheduled surgery or a chemotherapy regimen that's already been planned out. If the need is sudden, like an unexpected hospitalization, notify your employer as soon as practical.
Complete Form WH-380-F. This is the DOL's Certification of Health Care Provider for Family Member's Serious Health Condition — the form specifically built for family-care leave, distinct from the WH-380-E form used when you're the one who's sick. You can find every FMLA certification form on the DOL's forms page.
The family member's doctor completes the medical portion. They certify the serious health condition, the expected duration, and the specific care you'll need to provide — whether that's intermittent, continuous, or reduced-schedule leave.
The family member signs a medical release. This authorizes their doctor to share health information with your employer for certification purposes; without it, the certification can't move forward.
Submit within 15 days. Your employer must give you at least 15 calendar days to return the completed certification once they request it. Employers can request recertification periodically for longer-term conditions.
Your employer isn't allowed to ask for more information than the WH-380-F requires, and they can't contact the health care provider directly except through a designated health care professional if they need clarification — they have to go through you first.
Frequently Asked Questions
Can I take FMLA to care for my mother-in-law?
No. Federal FMLA does not cover parents-in-law — only your own biological, adoptive, step, or foster parent, or someone who stood in loco parentis for you as a child. Some state family leave laws define "family member" more broadly than federal law does, so it's worth checking your state's rules before assuming you're out of options entirely.
Can I take FMLA to care for my sibling?
No. Federal FMLA does not cover siblings — leave for family care is limited to a spouse, child, or parent. A handful of state laws extend coverage further than federal FMLA, so check your state's specific statute if a sibling's illness is the reason you need leave.
Can I take FMLA to care for my adult child?
Only if your adult child is 18 or older and incapable of self-care because of a mental or physical disability, as certified by a health care provider. A capable adult child with a serious health condition — even a life-threatening one — does not qualify you for FMLA leave under federal law.
Can I take FMLA to care for my grandparent or grandchild?
No, not under federal FMLA. Grandparents and grandchildren fall outside the three recognized relationships (spouse, child, parent). If you stood in loco parentis for a grandchild you raised as your own, that relationship may qualify under the "parent" definition applied to the grandchild — but a grandparent needing care from you generally does not.
What does "serious health condition" mean for the family member I'm caring for?
It means an illness, injury, impairment, or condition involving inpatient care, or ongoing treatment by a health care provider — which includes chronic conditions like diabetes or asthma, incapacity of more than three days combined with treatment, pregnancy, or a permanent condition like a severe stroke. The condition doesn't have to be life-threatening, but a minor illness that clears up without treatment usually doesn't qualify.
What if I need to care for multiple family members?
FMLA provides 12 weeks total per year, regardless of how many family members need care. You can't take 12 weeks for your mother's surgery and another 12 weeks for your father's cancer treatment in the same 12-month period — the entitlement is capped per employee, not per family member.
Can I take FMLA intermittently for family care?
Yes, if it's medically necessary. Taking your parent to weekly chemotherapy appointments, for example, qualifies as intermittent FMLA leave. Your parent's doctor has to certify the expected frequency and duration of each absence on the WH-380-F so your employer can track it against your 12-week bank.
Who fills out Form WH-380-F?
You start it, but the substantive medical certification is completed by the health care provider treating your family member — not you and not your employer. Your family member also has to sign a release authorizing their provider to share relevant health information with your employer. You submit the completed form; your employer can't require any certification beyond what WH-380-F asks for.
How long do I have to submit the WH-380-F certification?
At least 15 calendar days from when your employer requests it. If the health care provider needs more time, employers generally have to give a reasonable extension, but you should start the process as soon as you know leave is coming to avoid a gap between when leave starts and when it's officially approved.
Does my employer have to pay me while I'm on FMLA to care for a family member?
No. FMLA is unpaid, job-protected leave — it guarantees your position and your group health coverage, not your paycheck. Some employers let you use accrued PTO or sick leave concurrently with FMLA, and some states run paid family leave programs that provide partial wage replacement during FMLA-qualifying care. Check your state's rules and your employer's policy separately from your FMLA rights.
Can my employer ask my family member's doctor questions directly?
Only through a designated health care professional retained by your employer, and only to authenticate or clarify the certification you've already submitted — never to ask for additional medical information beyond what WH-380-F requires. Your employer is required to go through you first, not contact the provider directly on their own.
What happens if the certification doesn't come back in time?
Your employer can deny or delay FMLA-protected status for the leave until a complete certification is on file, though they generally have to give you a chance to fix an incomplete submission before denying it outright. This is why it helps to start the WH-380-F process the moment you know care is needed, rather than waiting until you're already out on leave.
Key Takeaways
Only spouse, child, and parent qualify for family-care leave under federal FMLA — siblings, grandparents, grandchildren, and in-laws don't count.
Adult children must be incapable of self-care to qualify; a capable adult child with a serious illness does not trigger FMLA leave.
"Serious health condition" covers more than hospitalization — chronic conditions, pregnancy, and multi-day incapacity with treatment all qualify.
Psychological comfort counts as care — you don't need to provide hands-on medical treatment to qualify.
Form WH-380-F is the required certification — the family member's own doctor completes the medical portion, not you.
12 weeks total per year applies across all family members combined, not per relationship.
State laws may cover more relationships than federal FMLA does — always check your specific state's law before assuming you're out of options.
Before you request leave, confirm you meet the underlying FMLA eligibility requirements — the 12-month tenure and 1,250-hour tests apply to family-care leave the same way they apply to your own medical leave. If you're not sure which certification form applies to your situation, our FMLA forms finder walks through each one, and the FMLA medical certification guide covers what happens after you submit the WH-380-F.
