If you are being held, the arraignment should come within a few days, maybe the next day. This has a lot to do with the charges and what level profile is this case. If there are many jurisdictions involved, they love to create a whole staged media scene patting themselves on the back. They read the charges before a magistrate that sets bail or not. In most cases, the prosecution makes a deal with the defense lawyer for a bail

It could take several hours or several days depending on the charges and the jurisdiction

It depends on the charges and the prior criminal history. If you have more information, we would be happy to try and give you a specific response

If she is held with a "no bond" stipulation, she is not going anywhere until the arraignment and subsequent trial.

If you "failed to appear", the judge issuing the warrant will most likely remand him to custody without bail. Bail is used to ensure compliance with all court appearances. You miss, you are now considered unlikely to appear in the future, so they keep you in jail (without bond) so that you will appear.

A $90,000 bond is substantial.  If it was reduced, that is a sign that the charges are not deemed as serious or maybe the role in this conspiracy is minor.  We'd need more information to be more helpful.

Using only the information you've given us, our opinion (and we are NOT lawyers) is that the bond is set at arraignment not during the warrant phase. Our instincts tell us that they owe money to the courts for child support or some fine that has triggered the warrant. You can call the Clerk of the Court and find out how the warrant was written. Your answers are in that document.

If the amount is "0" and he is still there, there is no bond.

Once your accused has gone before the magistrate, a bail amount is set. This bail amount becomes part of the record and usually you will have bail bondsmen contact the closest of kin to try and make a deal to bond your inmate out. Depending upon the amount, it is customary for the bail bondsman get a 10% non-refundable fee (of the total amount of the bond). Once you agree on the terms, the bondsman will go to the jail

It depends on the total bail set at the hearing
