FMLA to Care for a Family Member: Who Counts, What Care Means, and What the Doctor Has to Certify (2026)

Can you take FMLA to care for a family member?

Yes, for three relationships. An eligible employee may take up to 12 workweeks of unpaid, job-protected leave in a 12-month period to care for a spouse, a son or daughter, or a parent with a serious health condition. Spouse means a lawful husband or wife, including a same-sex or common-law spouse where the marriage was valid where entered. Son or daughter means a biological, adopted, foster or step child, a legal ward, or a child of a person standing in loco parentis, who is under 18 or is 18 or older and incapable of self-care because of a disability. Parent means a biological, adoptive, step or foster parent, or a person who stood in loco parentis to the employee as a child; parents-in-law are not included. Siblings, grandparents, grandchildren and domestic partners are not covered unless an in loco parentis relationship makes them a parent or child in fact. The employee must be needed to care for the family member, which includes physical care, psychological comfort and arranging care. A separate 26-week entitlement covers care for a covered servicemember and adds next of kin. Source: 29 U.S.C. 2611 and 2612; 29 CFR 825.122 and 825.124.

Who counts as a family member under the FMLA?

Three words carry the whole category: spouse, son or daughter, parent. Each has a regulatory definition, and the definitions are where most eligibility disputes about caregiving leave are decided. Spouse is a husband or wife as defined or recognized in the state where the marriage was entered into, including common-law marriage where the state recognizes it and same-sex marriage; since a 2015 rule change the test is the place of celebration, so a couple married in one state remain spouses under the FMLA wherever they work. Unmarried partners, including registered domestic partners and civil union partners, are not spouses under the federal Act, however long the relationship. That is the single most common gap between what a family looks like and what the FMLA covers.

Son or daughter is deliberately wide in one direction and firmly bounded in another. It includes a biological, adopted or foster child, a stepchild, a legal ward, and a child of a person standing in loco parentis, which means the employee has day-to-day responsibility for caring for and financially supporting the child, or either of those, without a biological or legal relationship. The bound is age: the child must be under 18, or 18 or older and incapable of self-care because of a mental or physical disability at the time the leave is to begin. Incapable of self-care means needing active assistance or supervision with three or more activities of daily living or instrumental activities of daily living, such as bathing, dressing, eating, cooking, shopping, taking medication or using the telephone, and disability is read through the ADA's definition. A 30-year-old daughter in the hospital after a car accident who cannot care for herself during recovery is a son or daughter for FMLA purposes during that period, because the incapacity is judged when the leave starts, not by whether it is permanent.

Parent means a biological, adoptive, step or foster father or mother, or any other individual who stood in loco parentis to the employee when the employee was a son or daughter. Parents-in-law are expressly excluded: an employee cannot take FMLA leave to care for a spouse's mother, though the spouse can. That exclusion is the second most common gap, and there is no in loco parentis route around it, because the relationship has to have existed when the employee was a child.

Does FMLA cover grandparents, siblings, or in-laws?

Not as such, and this is the answer people most often search for. A grandparent is not a parent, a sibling is not a son, daughter or parent, and an in-law is excluded by name. The Act leaves it there. But the in loco parentis language in both the parent and the child definitions opens a door that is wider than it looks, in both directions. If a grandmother raised the employee, standing in the place of a parent with day-to-day responsibility for care and support, she is the employee's parent under the FMLA, and the employee can take leave to care for her in old age. The Department of Labor's guidance says that the employee may be asked for reasonable documentation of the relationship, but that a simple written statement asserting the in loco parentis relationship is enough. A birth certificate that lists someone else as the parent does not defeat it.

The same door works for the next generation. An employee raising a grandchild, a niece, or a younger sibling, with day-to-day responsibility for the child or financial support of the child, stands in loco parentis to that child, and the child is the employee's son or daughter for FMLA purposes. The 2010 interpretation made clear that either responsibility is enough: an employee who provides daily care for a partner's child without contributing financially qualifies, and so does one who pays for a child's upbringing while the child lives with a grandparent. There is no requirement that the employee be the only person standing in that position, so a child can have more than two FMLA parents. What the door does not cover is the adult sibling or grandparent relationship as it usually exists, one of love and obligation without the parental history, and it does not cover any in-law.

Where the FMLA stops, state programs often continue. Every state paid family and medical leave program uses a wider family definition than the federal Act. Siblings, grandparents and grandchildren are covered in most of them; domestic partners in nearly all; and Connecticut, Oregon, Colorado, New Jersey, Washington and Minnesota extend coverage, each in its own words, to a person who is not a relative but whose close association with the employee is the equivalent of a family relationship, sometimes called the chosen family provision. An employee in one of those states caring for a sibling receives state benefits and, in most of the programs, state job protection, even though no FMLA leave is involved. The state-by-state family and medical leave grid on this site lists the definitions.

What does needed to care for mean?

The regulation gives the phrase a scope that is more generous than the word care suggests. It covers physical care when the family member is unable to care for their own basic medical, hygienic or nutritional needs or safety, or is unable to transport themselves to the doctor. It also covers psychological comfort and reassurance that would be beneficial to a child, spouse or parent with a serious health condition who is receiving inpatient or home care. It covers situations where the employee is needed to fill in for others who are caring for the family member, and to make arrangements for changes in care, such as the transfer to a nursing home. And it covers intermittent leave for these purposes, so a single afternoon spent driving a parent to an oncology appointment and sitting with them is needed care.

Two things the phrase does not require. The employee does not have to be the only person available, and the employee does not have to provide the care at every moment of the leave. Sitting with a hospitalized spouse while nurses do the medical work is psychological comfort and it qualifies. Being in the house while a home health aide handles the physical care, so that someone the parent knows is present, qualifies. What does not qualify is time that is not care in any of these senses: staying home because a family member is ill but does not need anything, or leave to handle a family member's affairs unrelated to the illness. The certification form asks the provider whether the patient needs care and for what, and asks the employee to describe the care they will provide, and the two together define the leave.

Travel is the edge case people ask about most. Leave to travel to a family member who is ill, in order to provide care on arrival, qualifies as needed care, and the travel time is FMLA leave. Leave to be near a family member who is being treated far away, to provide comfort, is the same. Leave for a family member's routine medical appointment that does not involve a serious health condition does not qualify, because there is no serious health condition to attach to, though several state sick leave laws cover it.

What is a serious health condition when the patient is a family member?

The definition is the same one that applies to the employee's own leave, applied to the family member. A serious health condition is an illness, injury, impairment or physical or mental condition that involves inpatient care, meaning an overnight stay in a hospital, hospice or residential medical care facility, or continuing treatment by a health care provider. Continuing treatment has five branches: incapacity of more than three consecutive full calendar days plus two visits within 30 days or one visit and a regimen of treatment; any incapacity due to pregnancy or prenatal care; a chronic condition requiring visits at least twice a year that may cause episodic incapacity; a permanent or long-term condition for which treatment may not be effective, such as Alzheimer's disease, a severe stroke or the terminal stages of a disease; and multiple treatments for restorative surgery or for a condition that would cause more than three days of incapacity if untreated, such as chemotherapy, radiation, dialysis or physical therapy after an injury.

The permanent and long-term branch is the one that carries most elder care. A parent with dementia does not have episodes of incapacity; the incapacity is constant and treatment cannot reverse it. The regulation requires only that the parent be under the continuing supervision of a health care provider, not that they be receiving active treatment, so a parent with advanced dementia living at home under a physician's care is a parent with a serious health condition every day, and the employee's leave to care for them, continuous or intermittent, is covered for as long as the 12 weeks last. The chronic branch carries most childhood conditions, asthma, diabetes and epilepsy among them, where the child needs a parent at home during a flare-up without a doctor's visit for each one.

What the definition excludes is the ordinary illness. A cold, the flu, an ear infection, an upset stomach or a routine dental problem are not serious health conditions unless complications develop that meet one of the tests, and an employee who stays home with a child who has a fever is not on FMLA leave for that day. State paid sick or paid leave laws, which exist in 20 states and the District of Columbia and in many cities, are what cover those days; the sick leave grid on this site sets them out.

Certification, notice, and the same-employer cap

The employer may require certification of the family member's serious health condition, and the Department of Labor's form for it is WH-380-F. The health care provider completes the medical part: the approximate start date and probable duration of the condition, the medical facts that make it serious, whether the patient needs care and for how long, and, for intermittent leave, the expected frequency and duration of episodes and appointments. The employee completes a short section describing the care they will provide and the schedule. As with the employee's own certification, a diagnosis is a medical fact the provider may include but need not; a statement that the patient has a permanent condition requiring continuing supervision and assistance with daily living is sufficient. The employer's rights are the same as for any certification: 15 calendar days for the employee to return it, seven more to cure a deficiency, authentication and clarification through HR rather than the supervisor, and second and third opinions at the employer's expense where the employer doubts a complete certification.

The family relationship itself may also be documented. The regulation lets the employer require reasonable documentation or a statement of the family relationship, and it says a simple statement asserting that the relationship exists is all that is needed; the employer may ask to see a birth certificate or court document but must return it. Notice follows the ordinary FMLA rules. Thirty days' notice where the need is foreseeable, such as a scheduled surgery or a planned course of treatment; as soon as practicable otherwise, which after a stroke or an accident means the day it happens or the next business day. The employee must give enough information for the employer to know the leave may be FMLA-qualifying, and stating that a parent has been hospitalized and needs care is enough.

One cap is specific to caregiving. Spouses who work for the same employer are limited to a combined 12 weeks of leave in a 12-month period for the care of a parent with a serious health condition, as well as for birth, bonding and placement. The cap does not apply to leave to care for a child or a spouse, which each spouse takes from their own entitlement. Two employees at the same company caring for the same parent have, between them, 12 weeks for that parent; two employees at different companies have 24.

Military caregiver leave: the one place the list is longer

The FMLA has a second, larger entitlement for one situation. An eligible employee who is the spouse, son, daughter, parent or next of kin of a covered servicemember with a serious injury or illness incurred or aggravated in the line of duty may take up to 26 workweeks of leave in a single 12-month period to care for them. Next of kin means the nearest blood relative other than a spouse, parent, son or daughter, in a defined order of priority: a blood relative granted legal custody, then siblings, grandparents, aunts and uncles, and first cousins, unless the servicemember has designated another blood relative in writing. This is the only FMLA leave a sibling can take as a sibling.

A covered servicemember is a current member of the Armed Forces, including the National Guard and Reserves, undergoing treatment, recuperation or therapy, in outpatient status, or on the temporary disability retired list for a serious injury or illness, and, since the 2010 amendments, a veteran who was a member of the Armed Forces within the five years before the treatment and who is undergoing treatment for a qualifying serious injury or illness. The 26 weeks are a combined total with all other FMLA leave in that single 12-month period, which begins on the first day of the caregiver leave, and are available once per servicemember per injury. Certification is on form WH-385 or WH-385-V, and the definitions of a serious injury or illness are wider than the serious health condition standard, including conditions that may render the servicemember medically unfit for duty.

What pays while you care for someone?

The FMLA pays nothing, and unlike leave for the employee's own condition, caregiving leave has no disability insurance behind it: short-term disability pays only when the employee is the one unable to work. That leaves accrued paid leave and the state programs. An employee may substitute accrued vacation or PTO for the unpaid leave under the employer's normal paid leave policy, and may substitute sick leave if the policy allows sick leave to be used for family care, which the paid sick leave laws of most states with them now require for at least part of the balance. The employer may require the substitution, with notice, and the paid hours count against the 12 weeks.

In the 13 states and the District of Columbia with paid family leave, the caregiving benefit is the part of the program that has no federal or private analog. Every program pays a share of wages, from about 60 to 90 percent up to a weekly cap, for between six and 12 weeks of leave to care for a family member with a serious health condition, and every program uses the wider family definition described above. The paid leave calculator on this site estimates the weekly benefit for each program from a weekly wage. Where the employee is also FMLA-eligible, the two run at the same time and the state benefit is the pay for the FMLA leave; where the employee is caring for a sibling or a grandparent the FMLA does not cover, the state program is the whole of the protection, and in most of the programs it includes reinstatement.

Two worked examples

Dana's father, 78, has a stroke on a Tuesday. She calls her manager that evening and says her father is in the hospital and she needs to be with him, which is sufficient notice. Her employer, with 400 employees, sends the eligibility and rights and responsibilities notices and a WH-380-F within five business days. The neurologist certifies a permanent condition requiring continuing supervision and assistance with daily living, with an acute phase of four to six weeks of rehabilitation and ongoing appointments afterwards, and Dana describes the care: daily presence in the hospital and rehabilitation facility, then transport to appointments and coordination of home care. HR designates continuous FMLA leave for four weeks and intermittent leave thereafter. Dana uses 160 hours continuously, then 6 to 8 hours a week for appointments and care arrangements for the rest of the year, tracked in hours. Her employer requires PTO substitution, so the first two weeks are paid from her balance; her state has a paid family leave program, which pays 80 percent of her wage up to the cap for eight weeks of the caregiving. Her brother, who works for the same company, takes two weeks of continuous leave in the second month, which comes out of the same combined 12 weeks for a parent, leaving Dana with 10 weeks less what she has used. By the end of the year Dana has used 388 of 480 hours and the rest of her father's care is arranged around a home aide.

Malik's sister, 41, is diagnosed with leukemia and will spend weeks at a time in a hospital two states away. She is unmarried and their parents have died. Under the federal FMLA, Malik has no entitlement: a sister is not a spouse, child or parent, and nothing in their history amounts to in loco parentis. His options are his employer's policy, which offers a personal leave of absence at the employer's discretion, and, because he lives in Oregon, Paid Leave Oregon, which covers siblings and pays him a share of his wage for up to 12 weeks of family leave, with reinstatement rights because he has been with his employer more than 90 days. He takes eight weeks of state-paid family leave in two four-week blocks around his sister's treatment cycles and two weeks of unpaid personal leave to cover a complication. Had he lived in a state without a program, the personal leave and his PTO would have been the whole of it, which is the gap the caregiving definitions leave and the reason the state programs were written the way they were.
