Can a Jail Take Commissary Money for Old Unpaid Balances?

The situation you are describing is frustrating but legal, and unfortunately, more common than most families expect. Correctional facilities treat the inmate trust account as a financial account tied to the individual, and outstanding debts to the facility follow the person regardless of when the debt was incurred.

The types of fees that create these balances vary by facility and jurisdiction. Many jails charge a medical copay each time an inmate receives healthcare, typically a few dollars per visit. Dental services often carry similar fees. Some facilities, particularly at the county level, charge a daily bed fee, sometimes called a pay-to-stay charge, which accumulates over the length of the stay. These amounts can add up significantly over weeks or months, and if the inmate was released without sufficient funds to cover the balance, the debt remains on the facility's books under their name.

When the inmate returns to the same facility, the system recognizes the outstanding balance and automatically applies incoming funds toward it before allowing the inmate to access the remainder for commissary spending. The facility considers this a legitimate collection of a debt owed to the institution.

The question of why this was not addressed at the time of the prior release is a fair one. Ideally facilities would resolve these balances during the release process, but in practice many do not have a mechanism to collect on departing inmates who have no funds at the time of release, so the balance simply sits until the person returns.

If the charges seem incorrect or inflated, your boyfriend can request an itemized accounting of the balance from the facility's finance or inmate accounts department. That documentation would show exactly what fees were assessed and when, and gives you a basis to dispute anything that appears inaccurate.
