OPINION
Opinion By
In this original proceeding, we must decide whether the trial court judge erred in not giving relator John Michael Daisy additional credit for time served. Because we conclude the trial court erred, we conditionally grant the writ.
Background
Relator was arrested and jailed in the Irving jail on July 31, 2001 for an assault involving family violence. On August 7, 2001, relator was transferred from the Irving jail to the Dallas County Jail. On that same date, a magistrate informed relator of his rights and set bail in the amount of $15,000. Relator did not post bail, and remained in jail until the date of his trial. On November 8, 2001, relator was convicted of felony assault involving family violence. See Tex. Pen.Code Ann. § 22.01(a), (b)(2) (Vernon Supp.2004-05). Punishment was assessed at five years’ imprisonment and a $500 fine. The trial court’s judgment gave appellant credit for presen-tence time served from August 7, 2001 to November 8, 2001. Appellant appealed, *924 and this Court affirmed the trial court’s judgment on November 15, 2002 and issued its mandate on February 11, 2003. Appellant did not raise the issue of back time credit on appeal.
Appellant thereafter filed a motion for a nunc pro tunc judgment, seeking credit for the time he was in jail from the date of his arrest on July 31, 2001 until August 7, 2001. There are several form letters in the clerk’s record from the trial court judge to relator giving various reasons why the judge could not or would not rule on his motion. On January 3, 2005, relator filed a pro se petition for writ of mandamus complaining of the trial judge’s failure to grant him the additional back time credit. Neither the State nor the respondent filed a response.
Analysis
To obtain mandamus relief, relator must demonstrate that (1) he has no other adequate legal remedy, and (2) under the relevant facts and law, the act sought to be compelled is purely ministerial.
State ex rel. Hill v. Court of Appeals for the Fifth Dist.,
The code of criminal procedure provides that
[i]n all criminal cases the judge of the court in which the defendant was convicted shall give the defendant credit on his sentence for the time that the defendant has spent in jail in said cause, other than time served as a condition of community supervision, from the time of his arrest and confinement until his sentence by the trial court.
Tex.Code Crim. Proc. Ann. art. 42.03, § 2(a) (Vernon Supp.2004-05) (emphasis added);
see also Ex parte Ybarra,
Relator filed a motion seeking additional credit for the time he spent in the Irving jail from the date of his arrest on July 31, 2001 until he was transferred to the Dallas County Jail on August 7, 2001. The record shows that relator was confined on the family violence assault during that time period. Therefore, he is entitled to additional back time credit for the dates of July 31, 2001 through August 6, 2001. The trial judge’s failure to enter a nunc pro tunc order giving him that credit violated a ministerial duty, for which relator’s remedy is mandamus relief.
Accordingly, we conditionally granted relator’s petition for writ of mandamus. We order the trial judge to entered a nunc pro tunc order giving relator presentence credit for the time he spent in the Irving jail from July 31, 2001 through August 6, 2001. The trial judge is ordered to file a *925 certified copy of its nunc pro tunc order with this Court within thirty days of the date of this opinion. Should the trial court fail to do so, the writ will issue.
