Household liabilities are the combined debts and financial obligations owed by everyone living under one roof, from a 30-year mortgage down to an overdue medical bill. They sit opposite assets like savings, retirement accounts, and home equity on the family balance sheet. Subtract total liabilities from total assets and you have household net worth, the figure lenders, divorce courts, and estate administrators use to measure a family’s real financial position.
The categories below cover what typically appears on that liability side, and the legal rules that make each one behave differently when money gets tight.
Secured Debts Tied to Property
Secured liabilities are loans backed by a specific asset. Stop paying, and the lender can take the property. A primary mortgage is the classic example: the home itself is the collateral. A home equity line of credit (HELOC) works the same way, letting an owner borrow against built-up equity during a draw period. Auto loans follow the same logic, with the lender holding the title until the balance clears.
When one of these loans closes, the lender records a lien in public records. That lien blocks any sale or transfer of the property free and clear until the debt is satisfied. Mortgage default triggers foreclosure. Auto loan default is faster still: in most states a lender can repossess a vehicle the moment the borrower defaults, without a court order, as long as no threats or force are involved.1Federal Trade Commission. Vehicle Repossession
Collateral lowers the lender’s risk, which is why secured debts carry lower interest rates than unsecured ones. The tradeoff is that falling behind costs more than money. Default clauses can trigger within 30 to 90 days of a missed payment, and once the lender acts, the borrower loses both the property and any equity in it. For most families, the mortgage and the car loan are the two largest liabilities on the books.
Unsecured Consumer and Revolving Debt
Unsecured liabilities have no collateral. The lender is betting on income and credit history, and that risk is priced into the rate. Credit card interest averaged around 22.8% as of 2023, the highest level the Federal Reserve has recorded since it began tracking the data in 1994.2Consumer Financial Protection Bureau. Credit Card Interest Rate Margins at All-Time High Individual rates run from the low teens for strong credit to over 30% for subprime borrowers. Late fees typically fall between $30 and $43, and a penalty interest rate can kick in after 60 days of missed payments.
Personal loans and medical financing plans belong in this category too. With no asset to seize, a creditor’s only path after default is a lawsuit. Win a judgment, and the creditor can pursue wage garnishment or a bank levy. Federal law caps consumer wage garnishment at 25% of disposable earnings, or the amount by which weekly earnings exceed 30 times the federal minimum wage, whichever is less.3Office of the Law Revision Counsel. 15 US Code 1673 – Restriction on Garnishment Seven states prohibit consumer wage garnishment entirely.
Student Loans
Student loans fund tuition, housing, and living expenses, and they split into two very different legal universes. Federal student loans fall under the Higher Education Act, which provides income-driven repayment, deferment during hardship, and forgiveness for certain public service and teaching roles.4Federal Student Aid. Higher Education Act of 1965 – Table of Contents Private student loans are ordinary contracts with banks or credit unions, with limited flexibility and few deferment options.
The sharpest difference from other debts shows up in bankruptcy. Student loans are generally non-dischargeable unless the borrower can prove “undue hardship,” a standard that requires showing an inability to maintain even a minimal standard of living while making payments.5Office of the Law Revision Counsel. 11 US Code 523 – Exceptions to Discharge The Department of Justice has updated its guidance to make that standard somewhat less punishing, but the bar remains high. For balance sheet purposes, student loans are the stickiest liability a household carries.
Medical Debt
Medical liabilities arise from the gap between what care costs and what insurance covers. They run from a few hundred dollars for an urgent care visit to six figures for a hospitalization. Unlike consumer debt, medical debt is almost never a choice, and the legal system has begun to reflect that.
The three major credit bureaus voluntarily agreed in 2023 to stop reporting medical debts under $500. A broader federal rule from the Consumer Financial Protection Bureau would have removed all medical debt from credit reports, but a federal court vacated that rule in July 2025, finding it exceeded the agency’s authority under the Fair Credit Reporting Act.6Consumer Financial Protection Bureau. CFPB Finalizes Rule to Remove Medical Bills from Credit Reports Some states have added their own protections; coverage varies.
Unpaid medical bills that reach collections follow the same legal path as other unsecured debts: the collector can sue, get a judgment, and pursue garnishment. The practical difference is that medical providers are often willing to negotiate payment plans, and many hospitals are required to offer financial assistance to low-income patients, particularly before an account reaches collections.
Tax Debt and Court-Ordered Obligations
Some liabilities exist because a law or a judge says so. These are the hardest to negotiate away.
Unpaid Taxes
Unpaid federal income taxes create a legal claim against everything a taxpayer owns: real estate, bank accounts, wages, and personal property. The IRS doesn’t need a court order to enforce it. After assessing the liability and sending a notice demanding payment, the agency can file a federal tax lien that attaches to all current and future property, and can eventually levy assets to satisfy the balance.7Internal Revenue Service. Understanding a Federal Tax Lien The IRS collects administratively under IRC § 6331, without first going to court.8Internal Revenue Service. 5.17.3 Levy and Sale Costs compound quickly: the failure-to-pay penalty runs half a percent per month, climbing to 1% after a notice of intent to levy, capped at 25% of the tax owed.9Internal Revenue Service. Topic No. 653, IRS Notices and Bills, Penalties and Interest Charges Property taxes owed to local jurisdictions carry their own penalties and can end in a tax sale of the home.
Child Support and Alimony
Court-ordered support payments are among the most aggressively enforced liabilities a household can carry. Every state authorizes the suspension of driver’s, professional, and recreational licenses for parents who fall behind on child support. Enforcement can include contempt-of-court proceedings that carry possible jail time. These obligations are explicitly non-dischargeable in bankruptcy, meaning they survive a Chapter 7 filing that wipes out credit cards and medical bills.5Office of the Law Revision Counsel. 11 US Code 523 – Exceptions to Discharge Alimony ordered in a divorce decree receives the same treatment and stays in force until a court modifies or terminates the order.
Co-Signed Debts
Co-signing a loan creates a liability many households forget until something goes wrong. When you co-sign, you’re guaranteeing the full balance. If the primary borrower misses payments, the lender can come after you immediately, without first trying to collect from them. Federal law requires lenders to spell this out in a separate Notice to Cosigner before you sign.10eCFR. 16 CFR 444.3 – Unfair or Deceptive Cosigner Practices The notice includes a blunt warning: “You may have to pay up to the full amount of the debt if the borrower does not pay. You may also have to pay late fees or collection costs, which increase this amount.” The FTC recommends asking the lender to agree in writing to notify you if the primary borrower misses a payment, so you can catch up before it escalates.11Consumer.ftc.gov. Cosigning a Loan FAQs
Co-signed debts are real liabilities on your balance sheet. Mortgage lenders count them when calculating your debt-to-income ratio even when the primary borrower has never missed a payment. That is where co-signing often blindsides people: it can shrink your borrowing capacity for years.
Spousal Liability and Marital Property
Whether you’re on the hook for your spouse’s debts depends on where you live. The country runs on two systems that produce very different results.
Nine states use community property rules: Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin.12Internal Revenue Service. Publication 555 (12/2024), Community Property Debts either spouse incurs during the marriage are generally treated as joint. A creditor can pursue marital assets and income even if only one spouse signed the paperwork. Separate property, like an inheritance to one spouse, is usually shielded.
In the common law states, you’re generally not liable for debts your spouse takes on alone. The main exceptions are debts both spouses signed for, debts that benefited the family, and the doctrine of necessaries. That last one catches people off guard: in many states, one spouse can be held responsible for the other’s essential medical expenses without ever signing anything. Prenuptial agreements don’t override this doctrine, because the medical provider is a third party who never agreed to those terms.
In divorce, debts get divided along with assets. Community property states generally split marital debts equally. Common law states divide based on who incurred the debt and who benefited. Either way, a divorce decree does not bind the original creditor. If the court assigns a joint credit card to your ex and they stop paying, the card issuer can still come after you.
What Happens to Household Debt After Death
A common assumption is that debts die with the borrower. They don’t. Outstanding liabilities become claims against the estate, and creditors have a legal right to be paid from estate assets before heirs receive anything.
Federal debts take priority. Under 31 U.S.C. § 3713, when an estate can’t cover everything, government claims come first, and an executor who pays heirs before satisfying federal obligations can be held personally liable for the shortfall.13Office of the Law Revision Counsel. 31 US Code 3713 – Priority of Government Claims After federal and state taxes, secured creditors generally come next, followed by unsecured creditors. Exact priority varies by state.
Family members are not personally responsible for a deceased relative’s debts unless they co-signed, held a joint account, or live in a community property state where the debt was marital. Being an authorized user on a credit card does not make you liable for the balance after the cardholder dies, despite what a collector might claim.14Consumer Financial Protection Bureau. Am I Liable to Repay an Authorized User Debt If a collector insists you owe, ask for proof that you co-signed the account.
How Liabilities Shape Borrowing and Net Worth
Household net worth is simple math: total assets minus total liabilities. Assets include bank accounts, retirement funds, investment portfolios, and the market value of real property. Liabilities include every category above. The result is real family equity, and it can be negative. A family with a $300,000 home, $50,000 in savings, and $400,000 in combined mortgage, student loan, and credit card debt has a net worth of negative $50,000.
Lenders also look at the debt-to-income ratio (DTI), which compares monthly debt payments to gross monthly income. For conventional mortgages, Fannie Mae generally caps DTI at 36% for manually underwritten loans, though borrowers with strong credit and reserves can qualify with ratios up to 45%. Loans run through Fannie Mae’s automated system can reach 50%.15Fannie Mae. Debt-to-Income Ratios Every household liability feeds that calculation, including co-signed debts and minimum credit card payments.
When liabilities become unmanageable, certain assets stay out of reach. Federal law limits consumer wage garnishment to 25% of disposable earnings.3Office of the Law Revision Counsel. 15 US Code 1673 – Restriction on Garnishment Every state offers a homestead exemption that shields some equity in a primary residence, though the amount varies from almost nothing in a few states to unlimited protection in others, often with acreage caps. Retirement accounts get strong federal protection under ERISA, and Social Security benefits are generally exempt from garnishment for consumer debt. Knowing what creditors can reach, and what they can’t, matters as much as knowing what you owe.
