The Kitchen-Table Hook

Late at the kitchen table is where families finally say the word bankruptcy out loud. So Ava did what a worried spouse does — she sat down across from her husband, attorney Michael Benavides, and asked him the questions Sacramento, Stockton, Modesto, and Northern California families actually lose sleep over. He answered each one straight, in plain English, with the California law.

Ava Asks, Michael Answers — Allowable Expense Limits in Chapter 13: The Trustee's Math

Ava: Can we talk about Allowable Expense Limits in Chapter 13? Where do we even start?

Michael, Esq.: In Chapter 13, the size of your monthly payment depends on your “disposable income" — what is left after allowed expenses. But you do not simply list your real spending and call it a day. The trustee applies a specific set of expense rules, many tied to IRS standards, and understanding them explains why your plan payment is what it is.

Ava: Can you explain why expenses are standardized?

Michael, Esq.: If filers could deduct unlimited expenses, everyone would claim they have nothing left to pay creditors. So the law uses a mix of standardized allowances and actual costs to calculate disposable income, especially for above-median filers. The goal is a consistent, defensible number rather than a wish list.

Ava: Help me understand iRS national and local standards.

Michael, Esq.: For categories like food, clothing, personal care, and out-of-pocket health costs, the calculation uses IRS National Standards — fixed allowances based on household size, regardless of what you actually spend. For housing and utilities and for transportation, it uses IRS Local Standards tied to your county and region. These caps mean you get a set allowance even if your real spending differs. This cuts both ways. If you spend less than the standard, you may still get the standard allowance. If you spend more, you generally cannot deduct the excess unless a special circumstance justifies it.

Ava: Tell me about actual expenses that count.

Michael, Esq.: Some costs are taken at their actual amount rather than a standard: secured-debt payments (your mortgage, car), required taxes, mandatory payroll deductions, child care, health insurance, and certain necessary expenses. These real numbers reduce disposable income directly, which is why a filer with a big mortgage and a car payment may have little left for unsecured creditors.

Ava: Explain where disputes happen.

Michael, Esq.: The friction points are predictable: expenses above the standards, vehicle ownership allowances when a car is paid off, large discretionary costs, and “special circumstances" claims. Trustees scrutinize budgets that look padded. The art is documenting legitimate necessary expenses — a medically necessary cost, a long commute, support of a dependent — in a way the trustee accepts.

Ava: Can you explain why this determines your payment?

Michael, Esq.: Because the plan must commit your disposable income, the expense math directly sets how much you pay each month and over the life of the plan. Getting allowed expenses right — claiming everything you are entitled to without overreaching — is how you arrive at a payment that is both confirmable and survivable. Overstate expenses and the trustee objects; understate them and you overpay for years.

Ava: Okay — bottom line. What do we take away from all this?

Michael, Esq.: Chapter 13 disposable income is calculated with standardized IRS allowances for everyday categories plus actual amounts for secured debts, taxes, and certain necessary costs. The trustee's math, not your raw spending, sets your plan payment. Claiming every legitimate expense — accurately and with documentation — is what produces a payment you can live with, which is exactly why this calculation rewards experienced counsel. One step at a time, health over stress — that's how we'll work through it.

What to Do

The thread through every answer is the same: California gives families more protection and more options than they think — but the relief turns on acting before a deadline (a sale date, a garnishment, a levy) closes the door. If this is the conversation at your kitchen table, a free consult turns the guessing into a plan. Bring the worst letter you got this week; we'll start there.
