v.
WE CARE TRANSPORTATION SERVICES, INC., et al.
No. A11A1440.
Court of Appeals of Georgia.
September 1, 2011.
Reconsideration Denied October 7, 2011.
Michael Bernard King, for appellant.
Busch, Slipakoff & Schuh, Michael Patrick Bain, for appellee.
PHIPPS, Presiding Judge.
Gladys E. Mapp, as representative of the estate of Vera L. Travis, appeals the trial court's order dismissing her Renewed Complaint for Personal Injuries (the "renewed complaint"). In their appellate briefs, all parties refer to the renewed complaint. Because the appellate record does not contain a copy of the renewed complaint, this court ordered the trial court to transmit it for inclusion in the record on appeal and sent *264 copies of its order to all parties. In response, the trial court clerk submitted a letter stating that the clerk's office did not have a copy of the renewed complaint in its files, but had only a civil case initiation form. The appellant has made no effort to supplement the appellate record.
We review a trial court's ruling on a motion to dismiss de novo.[1] We cannot resolve the issues raised in this appeal because the appellant has failed to satisfy her "burden of providing us with a sufficient record to enable us to review the enumeration[] of error[s] raised."[2] And the party asserting error must show it by the record; "mere assertions of error in briefs cannot satisfy this duty."[3] Under these circumstances, we must assume that the record supported the trial court's ruling.[4]
Judgment affirmed.
ANDREWS and McFADDEN, JJ., concur.
