OPINION

Opinion by

By letter dated January 13, 2012, we sent the parties a letter questioning our jurisdiction over this appeal. Specifically, it appears the notice of appeal was untimely filed. We requested that appellant file, by January 23, 2012, a letter brief addressing the jurisdictional issue with an opportunity for appellee to respond. As of today’s date, appellant has not filed a jurisdictional brief.

A party must file a notice of appeal within thirty days after the judgment is signed or within ninety days after the judgment is signed if a party files a timely motion for new trial. See Tex.R.App. P. 26.1(a). Without a timely filed notice of appeal, this Court lacks jurisdiction. Tex. RApp. P. 25.1(b).

Appellant is appealing a divorce decree signed on August 10, 2009. 1 Appellant filed a timely motion for new trial on September 4, 2009. Accordingly, appellant’s notice of appeal was due on November 8, 2009. Appellant filed her notice of appeal on July 23, 2010. Because appellant failed to file a timely notice of appeal, this Court lacks jurisdiction. See Tex.R.App. P. 25.1. Accordingly, we dismiss this appeal for *869 want of jurisdiction. See Tex.R.App. P. 42.3(a).
