Dillard, Presiding Judge. William Burkhalter, executor of the estate of Louise Ray Burkhalter, appeals the probate court’s grant of a declaratory judgment[1] to George Burkhalter and Nancy Ward, beneficiaries of Louise’s estate (“appellees”).[2] In granting the declaratory judgment, the probate court made several declarations adverse to William with regard to the enforceability of the in terrorem clause in Louise’s will. And in doing so, William argues the probate court erred in failing to address his counterclaim that the appellees violated the in terrorem clause, and as a result, have been disinherited. William also maintains the probate court erred by declaring that (1) the in terrorem clause is invalid as to an attack by an heir or beneficiary on the administration of the estate; (2) the in terrorem clause is invalid as to an attack by an heir or beneficiary on the management or expenditures of the Burkhalter Family Trust; (3) William must provide, within 60 days of the court’s order, a complete accounting of the calculation of the loss sustained as referenced in a certain provision in the will; and (4) the appellees may proceed with a petition for an accounting or for removal of the executor without violating the in terrorem clause. For the reasons noted infra, we affirm. The record shows that Louise died on March 18, 2015, and her will was admitted to probate.[3] On June 10, 2015, the probate court issued letters testamentary qualifying William as the executor of the estate.[4] Shortly thereafter, on June 15, the appellees filed a petition for a declaratory judgment, seeking declarations that they may file future declaratory actions regarding the will, as well as a petition to remove William as executor, without violating the will’s in terrorem clause.[5] But with respect to the in terrorem clause, the appellees did not file copies of any proposed actions they intended to file in these proposed subsequent actions.[6] Relevant to this appeal, “Item IX” of Louise’s will contains the in terrorem clause, which provides, in relevant part: In order to assure there will be no dispute between my children concerning some of the expenditures made out of the Burkhalter Family Trust and other financial transactions with the assets in my estate, I want to declare that I have personally authorized these transactions . . . . I absolutely do not wish for my children to engage in legal disputes over this estate after my death. Therefore: Any person whether named as a beneficiary under my Last Will and Testament or becoming an heir of my estate by operation of law or any other means who attacks in any court of law any provision of my Last Will and Testament, or the administration of my estate, or the management or expenditures of the Burkhalter [F]amily [T]rust shall be specifically disinherited from any portion of my estate that would go to them either from provisions in my will or through operation[ ] of law. If this provision becomes operative, I direct that any portion of my estate that is involved be added to the residue and be distributed to the remaining beneficiaries, according to this, my Last Will and Testament.[7] On August 15, 2015, the probate court held a hearing on the appellees’ petition, after which it made the following rulings: “it denied the petition as to Item IV (the share calculation provision), granted the petition to file a second petition as to Item IX (the in terrorem provision), and granted the petition to file a second petition for the removal of the executor[ ].”[8] Specifically, as to Item IX, the court held that “a legatee may seek clarity as to the ‘validity of’ an in terrorem clause.”[9] To that end, the court “granted the petition to file another petition for declaratory judgment regarding the validity of the in terrorem clause in Item IX of the will.”[10] Lastly, the court concluded that a petition for the removal of the executor would not invoke the in terrorem clause because such a clause does not apply to “an action for an accounting and/or removal of an executor.”[11] William, as executor of testator’s will, appealed, challenging the probate court’s rulings that the petitioners may file (1) a future petition for a declaratory judgment regarding the validity of the in terrorem clause without violating the clause itself; and (2) a future petition to remove the executor without violating the in terrorem clause.[12] Ultimately, this Court concluded that the appellees’ claims and the probate court’s rulings on these matters are “flawed as a matter of law.”[13] In doing so, we first found “no authority supporting a procedure by which an interested party may file one declaratory judgment action to determine whether it may file a second declaratory judgment action to determine the validity of an in terrorem clause.”[14] Instead, a question regarding the “validity of an in terrorem clause should be resolved in the first declaratory judgment action raising that issue.”[15] And because we found no law allowing a second declaratory-judgment action on the question of the validity of an in terrorem clause, the probate court’s order was “vacated on this issue and remanded for that determination.”[16] In Burkhalter I, we also held the probate court erred in declaring that “a future petition to remove the executor[ ] would not violate the in terrorem clause found in the will.”[17] Specifically, we noted that the petition failed to specify the proposed claims against the executor sufficient for the probate court to have determined that those claims would not violate the in terrorem clause.[18] Furthermore, the petition did not include a proposed complaint or otherwise state the basis for a suit to remove the executor.[19] Under such circumstances, we held that the record, as it then existed, did not support the probate court’s conclusion that the petitioners’ proposed petition to remove the executor would not violate the in terrorem clause.[20] Thus, the probate court did not examine whether the proposed claims against the executor would violate the in terrorem clause, or whether—based on the particular allegations the appellees intended to make—the application of the in terrorem clause would be void.[21] For all of these reasons, we held that “the [probate] court erred in its rulings as to the petitioners’ proposed petitions for declaratory judgment regarding Item IX of the will and removal of the executor[ ] without violating the in terrorem clause.”[22] Therefore, we vacated the probate court’s judgment as to this ruling as well, and remanded the case for further proceeding consistent with our opinion.[23] Upon remand, the appellees filed an amended petition for a declaratory judgment, asking the probate court to (1) accept the amended petition; (2) decide whether the in terrorem clause in Item IX is valid; (3) declare that they are permitted to file a “Petition for Enforcement of Last Will and Testament of [Louise] and For an Accounting or, in the alternative, for Removal of Executor without being in violation of the in terrorem clause in IX of the [w]ill”; (4) declare that the filing of a declaratory action is not an attack upon the will itself; and (5) grant such other relief as the court may deem just and proper. As an exhibit to the amended petition, the appellees attached a “petition for enforcement of last will and testament of [testator] and for an accounting or, in the alternative, for removal of executor.” The appellees filed a supporting brief, and William filed a response. Following a hearing, the probate court entered an order on the appellees’ petition and made the following findings: (1) the in terrorem clause in Item IX of testator’s will is valid as to an attack by an heir or beneficiary on any provision in the will; (2) the in terrorem clause is invalid as to an attack on an heir or beneficiary on the administration of the estate, or the management of expenditures of the Burkhalter Family Trust; (3) William, as the executor, must provide—within 60 days of the court’s order—a complete accounting of the calculation of loss sustained as referenced in Item IX[24] of the will and provide same to the court and the appellees; and (4) the appellees may file a petition for an accounting, or in the alternative, removal of the executor without violating the in terrorem clause of the will, should they deem such is necessary after receipt of the loss calculations from the executor. This appeal follows. A probate court’s findings of fact after a declaratory judgment hearing are “analogous to a jury verdict and will not be interfered with if there is any evidence to support them;[25] but we review the probate court’s conclusions of law de novo.[26] Bearing this standard of review in mind, we turn to William’s claims of error. 1. William argues the probate court erred by failing to address his counterclaim that the appellees violated the in terrorem clause in Louise’s will and are therefore disinherited. We disagree. While the probate court did not expressly reference William’s counterclaim, in substance, the court resolved all of the relevant issues regarding the in terrorem clause and determined that the appellees were not disinherited merely because they sought declaratory relief regarding that provision. And indeed, in Burkhalter I, this Court expressly instructed the probate court that the filing of a declaratory-judgment action regarding the validity of an in terrorem clause “is not itself a violation of the in terrorem clause at issue[.]“[27] In addition to claiming that the appellees should be disinherited merely for initiating this action, William’s counterclaim complained that the appellees “began this action to remove [e]xecutor[ ] the day after the executor[ ] [was] installed without any objection to [his] installation by [the appellees] or otherwise and without the executor[ ] yet taking any action whatsoever to give rise to [his] removal.” But the probate court expressly addressed this allegation and even indicated that it shared William’s concerns. Specifically, the declaratory judgment stated, This court and [William] question the intent of the movants in filing a [d]eclaratory [j]udgment petition concerning an accounting and removal of executor[ ] a mere five days after the executor[ ] [was] appointed.[[28]]. On its face[,] the petition appears [to be] an anticipatory act; however, [William] [has] never denied that the beneficiary/movant, Gayle Ward, was never going to receive a distribution under the will. In other words, Gayle Ward already knew as soon as the will was probated that she was not going to receive a distribution under the estate . . . . The probate court explained that the reason Ward would not receive a distribution was related to a calculation of loss under a certain will provision, and she was simply asking to know how the executor made the calculation. According to the court, as a beneficiary, she had the right to do so. And William does not challenge the substance of the court’s ruling in this regard, but claims only that it failed to address the issue. But the record plainly shows that the court did so, and as a result, this claim is without merit. 2. William has abandoned his next three claims of error because he fails to provide relevant authority or make cognizable legal arguments to support them. (a) William first contends the probate court erred in finding that the in terrorem clause is invalid as to an attack by the appellees on the administration of the decedent’s estate. In the two pages William devotes to this argument, the only authority he cites is part of a sentence in Lanier v. Lanier,[29] noting “there is a limitation over to some other person; in which event the latter shall take.”[30] But rather than explain how Lanier applies to this case, he summarily contends, “here, the [c]ourt found that limiting an attack by a beneficiary against the administration of the will is against public policy. . . . Nothing could be further than the truth.” William then presents several assertions unsupported by authority or references to the record, and complains that the probate court failed to specify the public policy that supported its ruling.[31] Suffice it to say, William has failed to provide a discernable argument to support his bare assertion that the probate court erred in finding the in terrorem clause is invalid as to an attack by the appellees on the administration of the decedent’s estate, and therefore, he has abandoned this claim of error.[32] (b) Next, William contends the probate court erred in finding that the in terrorem clause is invalid as to an attack by an heir or beneficiary on the management or expenditures of the Burkhalter Family Trust. But again, other than stating that the arguments made as to Division 2 (a), supra, apply to this claim of error, William provides no authority or references to the record. Indeed, in the half page of his brief devoted to this claim, William merely provides a string of conclusory statements, without making any discernable argument or applying any relevant authority to the circumstances in this case. Thus, he has likewise abandoned his contention that the probate court erred in finding the appellees would not violate the in terrorem clause if they attacked the management or expenditures of the Burkhalter Family Trust.[33] (c) William also maintains the probate court erred in declaring that he must provide to the probate court and appellees—within 60 days of the date of its order—a complete accounting of the calculation of loss sustained (as referenced in the in terrorem clause).[34] As to this claim of error, William details his version of certain facts underlying this appeal, but cites to only two pages of the record to support it. And yet again, William fails to provide even a single reference to authority, much less apply that authority to the facts of this case or make a cognizable argument to support his contentions. As a result, William has also abandoned his claim that the probate court erred by ordering him to provide a complete accounting of the calculation of loss sustained within 60 days of its order.[35] 3. Finally, William argues the probate court erred in declaring that the appellees may file a petition for an accounting, or in the alternative, for removal of the executor without violating the in terrorem clause, should they deem it is necessary after receipt of the loss calculation. Yet again, we disagree. In Georgia, any person interested as a legatee, heir, or beneficiary of the estate of a decedent, by statute, “may have a declaration of rights or legal relations in respect thereto and a declaratory judgment to determine any question arising in the administration of the estate, including questions of construction of wills and other writings.”[36] And this statute is to be construed “[unstintingly] and administered so as to afford relief from uncertainty and insecurity with respect to rights, status, and other legal relations.”[37] Thus, under OCGA § 9-4-4 (a) (3), “an interested party may seek a declaration concerning the validity of an in terrorem clause.”[38] And an interested party filing such an action is “not itself a violation of the in terrorem clause at issue” because “[t]he search for the true meaning of a will is not an attack upon it.”[39] Furthermore, the Supreme Court of Georgia “sanctions the use of a declaratory judgment action to determine whether a proposed future action by the petitioner would violate an in terrorem clause.”[40] And as we have explained, “[t]ypically these proposed actions involve questions of whether and how an interested party may challenge actions by an executor, trustee or other fiduciary in the face of an in terrorem clause.”[41] In Sinclair v. Sinclair,[42] the Supreme Court of Georgia expressly held that “an action for accounting and removal of [e]xecutor clearly would not amount to a contest of the will by objecting to its probate; and such proceeding was clearly not an effort to break the will.”[43] The Sinclair Court further explained that the relevant will would not be broken if a beneficiary “succeeds in obtaining an accounting and removal of Executor. The effect of [her] success would leave the will in full force and effect.”[44] Moreover, our Supreme Court concluded that it “would violate public policy to construe the condition in terrorem so as to require the forfeiture of a beneficiary’s interest for bringing an action for accounting and removal of the executor.”[45] Ultimately, the Court held that “the trial court should have granted summary judgment in favor of [the beneficiary] because the in terrorem clause in [the decedent's] will does not and cannot require forfeiture of his interest if he files the proposed action for accounting and removal of [e]xecutor.”[46] Thus, under Sinclair, the probate court did not err in declaring the appellees could file a future petition for an accounting, or in the alternative, for removal of the executor, without violating the in terrorem clause. Nevertheless, in Burkhalter I, this Court acknowledged our Supreme Court’s holding in Sinclair, but distinguished it. Specifically, we first noted that, in Sinclair, the beneficiary sought to bring an action against the executor for his removal based “on the grounds of hostility, incompetence, selfdealing, flagrant abuses of fiduciary responsibilities and other wrongs, and for an accounting and other relief for breaches of trust, collusion, and negligence in the performance of his duties under the will.”[47] Thus, we concluded that the Sinclair Court had to “both construe the relevant in terrorem clause and compare it to the action proposed by the petitioner in the declaratory judgment action.”[48] We also explained that, “Sinclair noted that a declaration that a proposed action will not violate an in terrorem clause is limited to the type of proposed action that the petitioner has described.“[49] In Burkhalter I, the original petition for a declaratory judgment, which was amended upon remand, “fail[ed] to specify the proposed claims against the executor[ ] sufficient for the trial court to have determined that those claims would not violate the in terrorem clause.”[50] Thus, the probate court failed to examine whether any proposed allegation against the executor “would be a violation of the in terrorem clause or whether, based on those allegations, application of the in terrorem clause would be void.”[51] In remanding the case, we held that the probate court erred in failing “to analyze the issue of the petitioners’ proposed claim against the executor[ ] . . . .”[52] As explained supra, following our remand of this case in Burkhalter I, the appellees filed an amended petition for a declaratory judgment, requesting, inter alia, a declaration that they could file a petition for an accounting, or in the alternative, removal of the executor, without violating the in terrorem clause detailed supra. Although the amended petition did not detail the specific claims the appellees intended to assert against William, as the executor, they attached a proposed petition for an accounting or removal of executor as an exhibit to the petition. In the proposed petition, the appellees allege the executor failed to comply with and carry out the dispositive provisions of Louise’s will. They also allege the executor “failed to exercise good faith, care, and diligence in the management and administration of the Estate.” And as to potential misconduct by William, the probate court expressed concern that he admitted to distributing the estate to other beneficiaries and determining the appellees’ actions violated the in terrorem provision, all while these issues were pending before the court. The court concluded that this conduct “gives a legitimate question of settlement of accounts by [the] executor to the beneficiaries.” Unlike the petition at issue in Burkhalter I, the appellees’ amended petition provided the claims that they intended to assert in a future petition to remove the executor, and the probate court expressed its specific concerns over William’s actions as executor. Thus, under Sinclair, the probate court did not err in concluding that filing the proposed petition for an accounting, or in the alternative, removal of executor would not violate the will’s in terrorem clause.[53] Notwithstanding our Supreme Court’s holding in Sinclair, William summarily concludes the appellees will violate the in terrorem clause if they file a petition to remove the executor “for a frivolous reason, or for no reason at all . . . .” William also asserts that “[t]here seems little question[ ] that [his] actions . . . have been taken in direct accordance with the wishes of the [t]estator through her written [w]ill.” But those questions were not before the probate court, which only declared that the appellees could initiate a future action challenging William’s potential misconduct as executor. Moreover, William cites to no legal authority suggesting that a probate court is required to determine whether the appellees’ proposed claims against an executor are meritorious before determining the potential claims themselves would not violate the in terrorem clause. In Sinclair, our Supreme Court held that an action for an accounting or to remove an executor does not violate an in terrorem clause, explaining that “nothing herein ruled relates to the question as to whether the proposed action would be good or bad in law or equity.”[54] Furthermore, the Sinclair Court explained that “[i]t is not material to this [declaratory-judgment] suit that, in the proposed action, [the beneficiary] could conceivably choose to risk a forfeiture of his interest under the will by requesting relief beyond that which is outlined in his complaint for declaratory judgment.”[55] Similarly, here, it is immaterial that the appellees’ claims might fail in a future proceeding or that they might bring claims not detailed in their declaratory-judgment petition. And given the binding precedents in Sinclair and Burkhalter I, discussed supra, the probate court did not err in declaring that the appellees could file a future petition for an accounting, or in the alternative, removal of the executor without violating the in terrorem clause in the decedent’s will.[56] For all these reasons, we affirm the probate court’s order granting the appellees’ petition for a declaratory judgment. Judgment affirmed. Gobeil and Hodges, JJ., concur.
