Who counts as a family caregiver under US law?

US law has no single definition of a family caregiver. Each law or program draws its own line: the federal leave law counts three relationships, the disability law counts any relationship, a hospital counts whoever the patient names. The same person can be a caregiver at the hospital on Tuesday and not one at work on Wednesday. This post is general information, not legal advice.

Is there one legal definition of a family caregiver?

No. The closest thing to one is in the RAISE Family Caregivers Act, which became law on 22 January 2018. It defines a family caregiver as "an adult family member or other individual who has a significant relationship with, and who provides a broad range of assistance to, an individual with a chronic or other health condition, disability, or functional limitation."

That definition takes in a neighbor, a partner, a friend and a niece. It was written for a national strategy on supporting caregivers, and it does not give anyone leave, pay or a place in a hospital chart. Those come from other laws, each with a narrower definition of its own.

The number of people this touches is large. Caregiving in the US 2025, from AARP and the National Alliance for Caregiving, counts 63 million Americans providing care, one in every four adults, and reports that seven in ten of them are employed.

Who counts as a caregiver for job-protected leave?

For federal leave, you count if you are caring for your spouse, your child or your parent, and both you and your employer are covered. The Department of Labor's FMLA fact sheet sets out the test. You need to have worked for the employer for at least 12 months, with at least 1,250 hours in the 12 months before the leave, at a location where the employer has at least 50 employees within 75 miles.

If you meet it, you can take up to 12 workweeks of leave in a 12-month period to care for a family member with a serious health condition. The department's FMLA questions and answers add three things worth knowing:

• The law only requires unpaid leave.
• You return to the same or an equivalent job, and your group health benefits continue during the leave as if you were still working.
• When it is medically necessary, the leave can be taken in separate blocks or as a reduced schedule. That is how an afternoon a week for a parent's treatment can be FMLA leave.

The family list is short. A second fact sheet defines a parent as a biological, adoptive, step or foster parent, or anyone who stood in loco parentis to you when you were a child, and says the term "does not include parents 'in law.'" Siblings and grandparents are not on the list either.

In loco parentis is the exception to read closely. It means a person was in the role of a parent, with day-to-day responsibility to care for or financially support a child. If a grandmother or an aunt raised you, the department's fact sheet on the subject says she is your parent for FMLA purposes, and you can take leave to care for her.

Can an employer treat you differently for being a caregiver?

Being a caregiver is not a protected category under federal law, but two protections reach caregivers. The Equal Employment Opportunity Commission's 2007 enforcement guidance says so plainly: "the federal EEO laws do not prohibit discrimination against caregivers per se," and yet treating a caregiver worse can be unlawful when it rests on sex, disability or another protected characteristic.

The second protection is the association provision of the ADA. The EEOC describes it as prohibiting employment discrimination against a person "because of his or her known relationship or association with a person with a known disability." This is the widest definition in the list: the EEOC says the ADA "does not require a family relationship." An employer cannot pass you over on the assumption that your brother's illness will make you unreliable.

The limit is in the same document. Only applicants and employees who themselves have a disability are entitled to reasonable accommodation. The EEOC's example is that the ADA would not require an employer to change its leave policy for an employee who needs time off to care for a child with a disability. What the employer cannot do is refuse you leave it routinely grants to others because you want it for that reason.

Who counts under state paid family leave?

That depends on the state, and this is where the definitions widen. The Department of Labor's Women's Bureau reports that thirteen states and the District of Columbia have laws creating paid family and medical leave programs, and that no federal law guarantees paid family and medical leave to workers in the private sector.

Colorado shows how far a state can go. Its program, FAMLI, pays up to 12 weeks of leave to most employees, with no minimum time in the job. The FAMLI Division says a person does not have to be related by blood or marriage to be considered family, and that it looks at things like shared bills, who is named as an emergency contact, and whether the relationship created an expectation of care.

So the in-law, partner or close friend who is outside FMLA may be inside a state program. Each state runs its own, with its own benefit and its own definition of family. Search for your state's name with "paid family and medical leave" and read the program's own page.

Who counts as a caregiver at the hospital?

At the hospital, you count if the patient says you do. More than 40 states have passed a version of the CARE Act, a model law written by AARP. The AARP Public Policy Institute lists what it asks of a hospital:

• identify a family caregiver when a patient is admitted, and record that person in the medical record
• notify the family caregiver of the discharge plan
• offer the family caregiver training on the medical and nursing tasks they may be asked to do at home

HIPAA works the same way for conversations. The Department of Health and Human Services says a provider may share relevant information with family, friends or others involved in a patient's care when the patient agrees or does not object. A friend qualifies. Our guide to the first weeks of caring for a parent covers the written form many clinics ask for.

At admission, ask the nurse to put your name in the chart as the family caregiver, and ask to be told before discharge.

Who counts for public caregiver support?

For the main federal program, the test is the age or condition of the person you look after. The National Family Caregiver Support Program, run under the Older Americans Act, serves adult family members and other informal caregivers who look after someone aged 60 or older, or someone of any age with Alzheimer's disease or a related disorder. It also serves relatives aged 55 and older who are raising children or caring for adults with disabilities.

The services are delivered locally. The Eldercare Locator connects you to the agency for your area: call 800-677-1116.

Medicare has its own version. Medicare Part B covers caregiver training when the patient's provider decides the patient needs a caregiver's help for the treatment to succeed. The training covers things like giving medication, moving someone safely and wound care. After the Part B deductible, the cost is 20% of the Medicare-approved amount.

How do you find out which definitions fit you?

Answer five questions, in writing, and keep the answers with the person's health papers.

1. What is your relationship to the person: spouse, child, parent, in-law, sibling, friend? If a relative raised you, write that down too.
2. How long have you been with your employer, and how many people work there? Ask HR whether you are eligible for FMLA leave and which form the doctor fills in.
3. Which state do you work in, and does it have a paid leave program?
4. Are you named in the person's chart at their hospital and at each clinic?
5. How old is the person, and what have they been diagnosed with?

Most of these definitions end in paperwork: a certification from a doctor, a dated form at a clinic, a diagnosis someone has to state accurately on the phone. Those papers are easier to produce when they are already in one place.

Lifelong is where we keep them. It is a family health app for iPhone in which each person has their own account for their medications, conditions, appointments and documents. You upload a file, a photo or a scan, and Lifelong reads it and places it on a timeline. The person the record belongs to decides which family members see each category. The caregiving guide covers how a family shares the rest of the work.

What would a single definition change?

I think the gap between these definitions is the real subject. The federal leave law lists family by blood, marriage and who raised you. Care is organized by who shows up. A daughter-in-law driving to dialysis three times a week fits the RAISE Act's definition and can be the caregiver named in the hospital chart, and has no claim to FMLA leave for it.

The wide definition already exists in federal law. It has been there since 2018, attached to a strategy. Colorado has attached its version to a paycheck. If you want to see where this is heading, watch the state programs, and check your own before you need it.
