What is a subpoena?
A subpoena (pronounced “suh-pee-nah”) is an official notice that requires a person to come to court to testify and be a witness. The subpoena can also require the person to bring certain documents. For example, in a child support case, you may want to use the opposing party's employer's payroll records to prove his income or to use his bank records to prove that he can afford his share of the cost of supporting your child. If you can not get copies of those records yourself, you may choose to subpoena the employer's or the banks' records. The employer or the bank would then have to come to court with the documents you requested.
How can a subpoena help me?
Sometimes you need the testimony of someone who would not voluntarily come to court. Sometimes documents you do not have access to may strengthen your case. Serving a subpoena may provide the evidence you need to make a strong case in court.
