Inmates have one account where money is kept for them. The majority of the time that money is used for commissary needs so people tend to refer to the Inmate Trust Fund as “Commissary”. But commissary is not the only thing the money can be used for. Some medical treatments have co-payments that the inmate is required to pay. That money is deducted from his Trust Fund.
If an inmate causes damage to any jail property he can be charged with destruction of property. If he is found guilty the amount specified by the court to repair or replace the damaged item is taken from his Trust Fund. A new state law says that the Trust Fund can now show a negative balance. If an inmate must pay for the damage he caused but does not have the money in his Trust Fund it will show a negative balance. When someone puts money into his account that money will first go towards paying off the amount owed for the damage.
