Melanie Webster filed a complaint against Walgreen Co. by certified mail. Her first attempt at mailing the complaint was returned due to insufficient postage. By the time Webster resent and filed the complaint, the statute of limitations had run. Webster filed a motion to amend the filing date of her complaint to the date that she had originally sent the complaint, which was within the statute of limitations. The trial court denied the motion and thereafter granted Walgreen judgment on the pleadings because the complaint was untimely. Webster appeals the denial of her motion to amend the filing date. We conclude that “mailing” for purposes of the Indiana Trial Rules requires the sender to affix sufficient postage. Therefore, Webster’s complaint was not filed until her second attempt at mailing and was untimely. We affirm the judgment of the trial court.
