A bail amount with no release date visible is completely normal at this stage and it makes sense once you understand what each piece of information means.
Bail is set by the court to ensure your boyfriend shows up for his future court appearances. It is not a release date. It is a financial guarantee the court requires before considering releasing him while his case moves through the system. The bail amount appearing in a search simply means a judge has determined what that guarantee needs to be.
A release date only gets calculated and assigned after sentencing, meaning after the case is fully resolved through a plea, a trial, or another disposition. At the pre-trial stage where bail has been set but no court date has been resolved yet, there is nothing for the system to calculate a release date from. He has not been sentenced, so there is no sentence to calculate.
The court date is the next milestone to track. That is when the case moves forward toward resolution. To find out when that date is scheduled, contact the Clerk of the Court in the county where he was charged. The clerk's office maintains all case records, including upcoming court dates, charges filed, and the status of the case. That information is public record and accessible to anyone who asks.
In the meantime, staying in contact through letters and calls keeps communication open while the legal process plays out. InmadeAid can get a letter to him without your home address on the envelope while you wait for the court process to move forward.
