In December 2011, Addis International Money Transfer, LLC (“Addis”) and a majority of its members filed suit against Tsega Befekadu, the remaining member, for conversion and breach of fiduciary duty. The case went to trial, and on the first day, the trial court disqualified Befekadu’s counsel and declared a mistrial. Befe-kadu then proceeded pro se at the second trial, which resulted in the jury finding in favor of Addis on both claims. Befekadu appealed from the final judgment and the disqualification order. In a prior opinion, this Court concluded that the trial court did not apply the correct legal standards when disqualifying Befekadu’s counsel and remanded the case to the trial court for further proceedings. Befekadu v. Addis Intl. Money Transfer, LLC, 332 Ga. App. 103, 106-07 (1) (c) (772 SE2d 785) (2015). The case is again before us following the trial court’s *807determination on remand that Befekadu’s counsel is disqualified. For the reasons that follow, we find no error and affirm.
1. Befekadu asserts that the trial court erred in disqualifying his counsel, Larry Oldham, by misapplying the facts to the legal principles announced by this Court in our prior opinion. “The ultimate determination of whether an attorney should be disqualified from representing a client in a judicial proceeding rests in the sound discretion of the trial judge. This Court will not interfere with a trial court’s ruling absent abuse of that discretion.” (Citation and punctuation omitted.) Shuttleworth v. Rankin-Shuttleworth of Ga., LLC, 328 Ga. App. 593, 594 (759 SE2d 873) (2014).
In reviewing the trial court’s initial disqualification order, we found that the trial court appeared to have used the wrong standards in determining whether Oldham should be disqualified. First, we noted that it is not enough that an attorney previously represented an opposing party in the case. Befekadu, 332 Ga. App. at 106 (1) (c). Rather, an attorney is “disqualified from representing a party against a former client in a matter that is substantially related to the lawyer’s prior representation.” (Citation and punctuation omitted.) Id. A case is “substantially related to a prior representation if the two have material and logical connections.” (Citation omitted.) Id. Thus, we remanded the case to the trial court to “determine whether Addis can show that Oldham’s prior legal services on behalf of the LLC were substantially related to Addis’s litigation against Befekadu.” Id. at 107.
On remand, the trial court conducted a full evidentiary hearing at which “all the individuals” and Oldham testified, and the court heard argument of counsel. However, no transcript of the hearing is included in the record. Thus, although Befekadu argues on appeal1 that the trial court erred in reinstating the disqualification of Old-ham “after being provided with the factual and legal bases that showed there was no legal or factual basis for Oldham to be disqualified,” this Court has no method of reviewing what was presented to the trial court on remand. In the absence of a hearing transcript or any record evidence to the contrary, this Court must presume that the trial court properly considered the evidence before it and that its factual findings are supported by the evidence. Fine v. Fine, 281 Ga. 850, 852 (2) (642 SE2d 698) (2007). See also Tyson v. State, 301 Ga. App. 295, 298 (2) (687 SE2d 284) (2009) (physical precedent only).
*808Turning to the facts of this case, as found by the trial court on remand and by this Court in the prior appeal, Addis was formed as a limited liability company in 2006 with four members, including Befekadu, to provide money transferring services between the United States and Ethiopia. Befekadu, 332 Ga. App. at 103. Oldham was a friend of Befekadu’s, who had been authorized by the other members to hire Oldham to perform the work necessary to form the company At the time, Addis believed that Oldham had prepared an operating agreement, but he had not. However, Oldham had drafted the articles of incorporation, obtained the employer identification number (EIN) for Addis, and was its registered agent through 2011. Each of the members contributed at least $7,000 at the time they joined Addis, and at least some of them believed that they were conducting themselves pursuant to an operating agreement. Id. at 103-04.
In 2010, Befekadu wrote several checks on the LLC’s account that the other members alleged they were unaware of and were not authorized under the operating agreement, including a $20,000 payment to himself. Befekadu, 332 Ga. App. at 104. The total amount that Befekadu took from Addis was over $55,000, and a small portion of those funds were used to pay Oldham. Several months later and prior to filing suit, counsel for Addis contacted Oldham, requesting a copy of the operating agreement. Oldham confirmed by e-mail that he had never prepared an operating agreement for Addis and also informed Addis’s counsel that he would be representing Befekadu. Id. at 104.
The case subsequently went to trial. During the first trial, Mesfin Shibeshi, the president of Addis, was the first witness to testify On direct examination, Shibeshi testified that Addis had no operating agreement, interjecting, “In fact, this lawyer which is sitting there, he’s the one who tried to set it up. Actually, what he did was he opened the EIN number. That’s all he did.” Shibeshi also stated that Befekadu had written an unauthorized check for $750 to Oldham, Addis’s lawyer.
On cross-examination, Oldham began by asking, ‘"You and I have known each other for quite some time, correct?” before the trial court admonished Oldham to “[j]ust ask questions.” Shortly thereafter, opposing counsel objected to Oldham’s line of questioning as “testifying,” which objection the trial court sustained. And when Oldham began to question Shibeshi regarding Addis’s payments to his law firm, the trial court cut him off, explaining ‘You ask five questions in one and you’re testifying and you’re getting really close to having a problem.” Oldham then presented Shibeshi with a copy of what he *809characterized as the “articles of organization for the company.” The trial court excused the jury for the day and disqualified Oldham, stating:
You’re disqualified. You incorporated this corporation and now you’re up here fussing about what was done and when it was done and how it was done. And your name appears on all these documents. That’s a disqualification. You can’t do it on both sides. You’re trying to do it on both sides. . . .
Befekadu proceeded to a second trial several months later, and after an adverse judgment, appealed to this Court, which reversed the disqualification order and remanded the case for further proceedings.
On remand, the trial court concluded in a written order that Oldham’s prior representation was “substantially related” to Addis’s claims that Befekadu wrongfully converted company funds and breached his fiduciary duty because the lack of an operating agreement or any structure in place (contrary to what the other members of Addis were led to believe) allowed Befekadu to take the funds from Addis.2 Likewise, Befekadu’s defense was that he thought he was authorized to take the funds because no operating agreement was in place to prevent him from doing so.3 Thus, as found by the trial court, Oldham’s failure to prepare an operating agreement and his receipt of funds, which was not authorized by Addis, were core issues in this case. In addition, the trial court noted that in the first trial Oldham testified that he had been paid in 2010 by Befekadu, but then cross-examined the president of Addis on whether Oldham had been paid in 2006 for his work, thereby inserting his prior representation into the issues to be considered at trial.
We find that the trial court applied the correct legal standard as directed in our prior opinion and that the factual findings on remand support a material and logical connection between the matter presented at trial and Oldham’s prior representation. Moreover, we have reviewed the record and find no record evidence to the contrary in the previous trials, and in the absence of a transcript from the eviden-tiary hearing on remand, there is no basis to determine that the trial *810court abused its discretion.4 See Shuttleworth, 328 Ga. App. at 594. Accordingly, we affirm the trial court’s disqualification of Oldham on the grounds that the issues presented at trial were substantially related to Oldham’s prior representation.5 See Griggs v. Fletcher, 294 Ga. App. 60, 62 (1) (668 SE2d 521) (2008) (in the absence of a transcript, appellate court must presume the trial court ruled correctly) .
2. Befekadu also asserts several enumerations of error related to the second trial. However, Befekadu failed to support these enumerations with any argument or citation of authorities. Therefore, these enumerations are deemed abandoned.6 See Court of Appeals Rule 25 (c) (2); Toberman v. Larose Ltd. Partnership, 281 Ga. App. 775, 780 (3) (637 SE2d 158) (2006).
Judgment affirmed.
Miller, P. J., Ellington, P. J., Phipps, P. J., Dillard, Branch, Mercier and Peterson, JJ., concur. McFadden, J., dissents.We note that Oldham represents Befekadu on this appeal as he did on the previous one. We express no opinion as to whether it is appropriate for Oldham to continue his representation after having been disqualified by the trial court since no other party has sought his disqualification on appeal.
We note that the trial court’s order on remand is not a model of clarity but recognize that the order and its findings may suffer from lack of context given that we do not have the transcript of the evidentiary hearing on remand.
The trial court also addressed Befekadu’s contention that Addis waived disqualification, finding that Addis could not have anticipated that Oldham would attempt to testify regarding material issues through his cross-examination of Shibeshi.
The dissent takes issue with the order’s lack of specific facts to demonstrate a material and logical connection to Oldham’s prior representation of Addis, thereby concluding that the trial court’s ruling is contrary to the evidence. However, the dissent ignores the fact that the trial court conducted a full evidentiary hearing that included testimony from all parties, and that this evidence is not before us. We do not believe it is appropriate for this Court to discount this evidence of the relationship between the issues presented at trial and Oldham’s prior representation, which the trial court heard and relied upon in issuing its order on remand.
The trial court also found that Oldham’s representation of Befekadu created an impermissible appearance of impropriety, citing Rule 1.9 (a) of the Georgia Rules of Professional Conduct, and that Oldham attempted to act as both an advocate and a witness in violation of Rule 3.7 (a) of the Georgia Rules of Professional Conduct. Because we affirm the trial court’s order on other grounds, we do not need to address these separate issues. However, we note that the dissent asserts that the trial court erred in its application of Rule 1.9 (a).
We note that this Court previously found that Befekadu had abandoned these enumerations of error in his prior appeal. Befekadu, 332 Ga. App. at 108-09 (2).
