How to Send Money to Someone at Martinez Detention Facility: Accepted Methods and Common Mistakes

Martinez Detention Facility accepts money orders and cashier's checks for inmate deposits. Stick with one of those two options - anything else will be rejected or delayed.

Make the money order or cashier's check out to "Office of the Sheriff." Write the inmate's name and booking number on the front so staff can match the funds to the right account.

Double-check the payee line and ID details. If the payment isn't made out to the Office of the Sheriff - or it's missing the inmate's name and booking number - it won't be deposited. Instead, it gets sealed in the inmate's property.

Don’t send cash or a personal check. If you do, the facility will return the entire envelope and everything inside it back to the sender.

Using the right payment type isn't enough - it also has to be filled out correctly. A money order or cashier's check that isn't made out to the Office of the Sheriff, or that's missing the inmate's name and booking number, will be sealed in the inmate's property rather than deposited. If the inmate is released, the payment gets returned to the sender.
