A property bond is a bond that posts the value of tangible property, such as real estate, in order to obtain a pre-trial release from jail. In some cases, the value of the property may need to be twice as high as the bail amount in order for a property bond to be accepted. A property bond is not allowed in every state. A property bond may be obtained from a bail agent. Depending on the law of the particular state, a court-appointed appraiser may need to asses the value of the property being used to post the bond. In other states, the value of the property as declared on tax documents may be considered adequate proof of its worth. If the warranty deed or tax statement relating to the property indicates that there is more than one owner, then each owner must sign an agreement indicating that the property may be used to finance a bond. When a property bond is issued, the court secures a lien against the property for the amount of the bail. If your brother fails to appear in court, a foreclosure action may be brought against the property. The court may then, after the foreclosure proceeding, collect on the bail amount that is owed. The court may also seek to recover, from the accused, the difference between any amount received in the foreclosure sale and the amount of the bail that was secured by the property.
