Qualifications for Jury Service
You do not need any special skills or legal knowledge to be a juror!
To be qualified to serve as a juror you must:
be at least 18 years of age;
be a citizen of the United States;
be a resident of this state and of the county in which you are to serve as a juror;
be qualified under the Constitution and laws to vote in the county in which you are to serve as a juror (Note: You do not have to be registered to vote to be qualified to vote);
be of sound mind and good moral character;
be able to read and write;
not have served as a juror for six days during the preceding three months in the county court or during the preceding six months in the district court; and
not have been convicted of, or be under indictment or other legal accusation for, misdemeanor theft or a felony.
*Note that the completion of deferred adjudication is not a disqualifying "conviction".
(Texas Government Code § 62.102. General Qualifications for Jury Service. Code of Criminal Procedure, Articles 35.16 et. seq.)
If you have any doubts as to your eligibility to serve on a jury, contact the judge or court as indicated on your jury summons.
