The Louisiana Declaration of Address by Defendant or Surety is a form that is used to inform the court of a defendant's address or surety's address. This form must be signed and dated by the defendant or surety, and it is filed with the court. There are two types of Louisiana Declaration of Address by Defendant or Surety: a Louisiana Declaration of Address by Defendant form and a Louisiana Declaration of Address by Surety form. The Louisiana Declaration of Address by Defendant form must include the defendant's full name, address, date of birth, driver's license number, and the date the form was signed and dated. The defendant must also sign the form and provide a witness to the signature. The Louisiana Declaration of Address by Surety form must include the name of the surety, their address, and the date the form was signed and dated. The surety must also sign the form and provide a witness to the signature. The surety must also provide proof of ownership of property used as collateral. The Louisiana Declaration of Address by Defendant or Surety forms are important because they provide the court with the defendant's or surety's current address. The court can then use this information, along with other evidence, to determine the defendant's whereabouts during a trial.
