The rights and responsibilities of a next of kin depend on whether your relative is incapacitated or deceased, what documents they left behind, and where they lived. In broad terms, being next of kin can let you make medical decisions when no healthcare agent was named, apply to administer the estate, and arrange burial or cremation. It does not automatically give you control over someone’s bank accounts, override a will or beneficiary designation, or make you personally responsible for their debts. The specifics are set by state law and by a legal hierarchy of relatives that courts and hospitals follow in a fixed order.
Who Counts as Next of Kin
Next of kin is a legal ranking, not a measure of who was closest. When someone dies or becomes incapacitated without a will, power of attorney, or other planning documents, state intestate succession laws decide who stands first in line. Most states follow the same pattern:
- Surviving spouse, who holds the highest priority in nearly every state.
- Adult children, including legally adopted children. Stepchildren do not inherit under intestate succession unless they were formally adopted.
- Parents, if no spouse or children survive.
- Siblings, with half-siblings treated the same as full siblings for inheriting from a shared parent.
- Grandparents, aunts, uncles, nieces, nephews, and more distant relatives in descending order of closeness.
Some states give legally recognized domestic partners equivalent or similar standing, but the position in the hierarchy varies. A domestic partner without state recognition may have no inheritance rights at all absent a will.
To exercise any of the rights that follow, expect to prove the relationship. A surviving spouse generally needs a marriage certificate; a child needs a birth certificate naming the deceased. Where no will exists and no probate case has been opened, an affidavit of heirship, a notarized sworn statement identifying the rightful heirs, can sometimes transfer property without a full probate proceeding.
Rights When a Relative Is Incapacitated
If your relative cannot make their own medical decisions and did not name a healthcare agent through a power of attorney or healthcare proxy, most states authorize the next of kin by statute to serve as a default surrogate decision-maker. The priority order mirrors the inheritance hierarchy: spouse, then adult children, then parents, then siblings.
Advance Directives Come First
A healthcare proxy or durable power of attorney for healthcare names a specific decision-maker, and that person’s authority overrides any family member, including a spouse. A living will, the person’s own written statement about end-of-life care, also takes priority over family input; if it refuses life-sustaining treatment, the next of kin cannot override it, though providers may use professional judgment in ambiguous situations.1National Institute on Aging. Advance Care Planning: Advance Directives for Health Care
Without any directive, the default surrogate decides based on what the patient would likely have wanted. When relatives at the same priority level disagree, the dispute can end up in court.
Medical Records
If you hold legal authority to make healthcare decisions under state law, HIPAA requires the hospital to treat you as a personal representative and share health information relevant to your role.2eCFR. 45 CFR 164.502 – Uses and Disclosures of Protected Health Information Even without formal authority, a provider may share information with a family member involved in care if, in the provider’s judgment, disclosure is in the patient’s best interest.3HHS.gov. Under HIPAA, When Can a Family Member Access an Individual’s PHI? Disclosures are limited to information relevant to the person’s care, not the complete medical history.
Finances Require a Court Order
Being next of kin does not let you touch an incapacitated relative’s bank accounts, pay their bills from those accounts, or sell their property. To manage finances you have to petition the court for appointment as a conservator; a guardian handles personal and healthcare decisions. The process involves a petition, notice to interested family members, and usually a medical evaluation confirming incapacity. Courts scrutinize these petitions because guardianship removes a person’s decision-making rights.
Responsibilities After a Death
Several obligations hit almost immediately after a relative dies, and some have deadlines attached.
Funeral and Burial Decisions
The next of kin has the legal right to decide whether the deceased is buried or cremated and to arrange services. If the deceased left written instructions, most states require survivors to follow them, though enforcement mechanisms vary.
Death Certificates
Registering the death with the vital records office is how you obtain certified copies of the death certificate, and you will need several. Government agencies, banks, insurance companies, and retirement plan administrators each require their own certified copy to process claims or close accounts.4USAGov. How to Get a Certified Copy of a Death Certificate Fees generally run from $5 to $34 per copy, with most states charging $15 to $20. Order extras upfront.
Social Security
The funeral home usually notifies the Social Security Administration of the death. If it doesn’t, call the SSA at 1-800-772-1213 with the deceased’s name, Social Security number, date of birth, and date of death.5Social Security Administration. What to Do When Someone Dies A surviving spouse who was living with the deceased, or certain dependent children, may claim a one-time lump-sum death payment of $255, but the application must be filed within two years of the death.6Social Security Administration. Lump-Sum Death Payment
Digital Accounts
Nearly every state has adopted a version of the Revised Uniform Fiduciary Access to Digital Assets Act. Under that framework, any settings the user configured through the platform itself (such as Google’s Inactive Account Manager or Facebook’s Legacy Contact) come first, followed by instructions in a will, followed by the platform’s terms of service. A personal representative can generally request a catalog of the deceased’s digital accounts, but reading the actual content of emails or private messages usually requires either the deceased’s prior consent or a court order. Files stored locally on a computer or external drive are estate property and accessible as such.
Getting Appointed to Administer the Estate
Being next of kin does not make you the estate administrator by default. That role requires a court appointment, and the next of kin applies by filing a petition with the probate court. If approved, the court issues Letters of Administration giving you legal authority to collect assets, pay debts, and distribute what remains.
Probate filing fees run from roughly $50 to $1,200 depending on the court and the size of the estate. The administrator typically has to publish a notice to creditors, giving anyone owed money a limited window (often a few months after publication) to file a claim. Known creditors must also be notified directly.
For smaller estates, many states offer a simplified process using a small estate affidavit that skips full probate. Thresholds vary widely, from as low as $5,000 to as high as $150,000, and some states exclude vehicles or real estate from the calculation. When an estate qualifies, an heir can collect bank balances and other assets with just the affidavit.
You Are Not Responsible for a Relative’s Debts (Usually)
Next of kin are not personally responsible for a deceased relative’s debts. Debts belong to the estate, and the administrator pays legitimate claims from estate assets before anything goes to heirs.7Federal Trade Commission. Debts and Deceased Relatives If the estate runs out, state law sets a priority order for which creditors get paid, and remaining debts are generally discharged. Heirs do not owe the difference.
A few situations do create personal liability:
- Co-signed loans. If you co-signed a car loan, mortgage, or credit card, you owe the full balance after the death.
- Joint account holders. A joint credit card holder is liable for the balance. An authorized user generally is not.
- Community property states. A surviving spouse in Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, or Wisconsin may be responsible for debts incurred during the marriage. Alaska allows couples to opt in by written agreement.8Consumer Financial Protection Bureau. Does a Person’s Debt Go Away When They Die?
- State filial responsibility laws. A handful of states can hold adult children responsible for certain healthcare debts of a deceased parent, though enforcement is uncommon.
What Collectors Cannot Do
Debt collectors routinely contact surviving family members, and the contact can feel like pressure to pay personally. Under federal law, collectors may discuss the deceased’s debts only with the spouse, the executor or administrator, a parent if the deceased was a minor, a legal guardian, or an attorney.7Federal Trade Commission. Debts and Deceased Relatives They can contact other relatives once to find those authorized people, but they cannot reveal debt details on that call.
Even when talking to someone authorized, collectors cannot imply the person is personally liable or should use their own money. They cannot call before 8 a.m. or after 9 p.m., and they cannot call your workplace after you tell them to stop.9Federal Trade Commission. FTC Issues Final Policy Statement on Collecting Debts of the Deceased If a collector is pressing you to pay from your own funds and none of the liability exceptions above apply, they are breaking the law.
Tax Filings
The personal representative files the deceased’s final federal income tax return, covering income from January 1 through the date of death. The usual filing thresholds that apply to living individuals determine whether a return is required. If no personal representative has been appointed, the person managing the deceased’s property is expected to file.10Internal Revenue Service. Topic No. 356, Decedents
A surviving spouse can file a joint return with the deceased for that final year. If a refund is due and you are not a surviving spouse filing jointly or a court-appointed representative, use IRS Form 1310 to claim it on the estate’s behalf.11Internal Revenue Service. Form 1310 – Statement of Person Claiming Refund Due a Deceased Taxpayer
Federal estate tax returns (Form 706) are required for 2026 only when gross estate assets exceed $15,000,000, a threshold raised by the One, Big, Beautiful Bill Act signed on July 4, 2025.12Internal Revenue Service. What’s New – Estate and Gift Tax Most estates fall well below this and owe no federal estate tax, but some states impose their own estate or inheritance taxes at much lower thresholds.
What Being Next of Kin Does Not Do
The hierarchy only governs assets that have no beneficiary designation or joint ownership directing them elsewhere. Life insurance policies, 401(k)s, IRAs, and bank accounts with payable-on-death or transfer-on-death designations pass directly to the named beneficiary and never enter probate. If a parent named a friend as beneficiary of a $500,000 life insurance policy, the surviving children have no legal claim to that money regardless of their next-of-kin status. Families routinely discover that most of a relative’s wealth sat in beneficiary-designated accounts, leaving the probate estate with comparatively little.
When Next of Kin Is Disqualified
The slayer rule prevents someone from inheriting from a person they intentionally killed. Courts treat the killer as though they died before the victim, passing their share to the next person in the hierarchy. A murder conviction creates a conclusive presumption, but civil courts can apply the rule without a criminal conviction if the evidence supports it. Nearly every state recognizes some version of this doctrine.
Courts can also refuse to appoint a next of kin as estate administrator if there is a conflict of interest, a history of financial mismanagement, or other circumstances against the estate’s interests. More distant relatives and creditors can file objections during probate.
When No Next of Kin Exists
If no identifiable living relatives can be found at any level of the hierarchy, the estate escheats to the state. A public administrator settles debts and manages what remains. Accounts without named beneficiaries eventually move to the state’s unclaimed property fund, which holds them for a period during which previously unknown heirs can come forward with proof of their relationship. After that window closes, the assets become state property permanently.
