¶ 1. We review, pursuant to SCR 2l.09(3m),1 the stipulation of the parties filed with the complaint of the Board of Attorneys Professional Responsibility (Board) alleging that Attorney Paul R. Horvath has engaged in professional misconduct. The parties stipulated that Attorney Horvath's license to practice law be suspended for six months as discipline for that misconduct, which consisted of his failing to comply promptly with a client's reasonable requests for information concerning the status of a collection matter and failing to explain that matter to the client, failing to cooperate in the Board's investigation of the client's grievance and disclose all facts and circumstances regarding it, failing to act with reasonable diligence and promptness on behalf of the client and misrepresenting to the client his having collected funds on its behalf, failing to deposit client funds in a trust account, and failing to maintain a trust account in compliance with SCR 20:1.15(c)(l)b.
¶ 2. We approve the parties' stipulation and determine that the professional misconduct established by the facts and conclusions set forth in it warrants a six-month license suspension. In addition to the seriousness of that misconduct, this is the third occasion the court has had to discipline Attorney Horvath for professional misconduct.
¶ 3. Attorney Horvath was admitted to practice law in Wisconsin in 1971 and practices in Appleton. In *6801984, the court publicly reprimanded him for neglecting a client's legal matter, misrepresenting to her that he had reached a settlement on a damage claim and paying her from his own funds, and failing to respond timely to inquiries from the Board regarding his conduct in the matter. In re Disciplinary Proceedings Against Horvath, 119 Wis. 2d 265, 349 N.W.2d 484 (1984). In May, 1991, he consented to a public reprimand from the Board for failing to commence a legal action on a client's collection matter for eight months, failing to respond to requests for information concerning the status of that matter by the collection agency that had referred the matter to him, and failing to respond to the Board's inquiries into the matter and provide copies of collection files on which he had been retained.
¶ 4. The facts to which the parties stipulated in this proceeding are as follows. In December, 1994, an out-of-state insurance company retained Attorney Horvath to collect a judgment it had obtained against a Wisconsin resident. In October, 1995, Attorney Horvath told the insurer's representative that he had collected some $300 from the judgment debtor and expected to receive the remainder within 30 days. Two months later the representative telephoned Attorney Horvath and left a message requesting a report of the status of the matter, but he did not return the call. A month later the representative wrote to Attorney Horvath requesting a status update, but he did not respond.
¶ 5. In March, 1996, Attorney Horvath told the insurer's attorney that the judgment had been collected in full and that he would send the funds and an accounting that day. When the attorney did not receive either the money or the accounting, he made further *681inquiries. Attorney Horvath then sent a copy of a trust account check he claimed to have sent a week after the attorney's telephone call. The check stub on the copy indicated that the total amount collected was $13,638, from which he had deducted $2727.60 as his fee. When the attorney told him the check had not been received, Attorney Horvath said he would stop payment on the original check and send a replacement check by overnight courier, but he did not do so. The insurer's attorney then sent a letter April 12, 1996 demanding prompt payment of the $10,910.40, but Attorney Horvath did not respond. In mid-October, 1996, the insurer filed an action against Attorney Horvath for the funds allegedly collected from the judgment debtor and, when Attorney Horvath did not answer the complaint, obtained a default judgment.
¶ 6. When the Board asked him for information concerning the grievance that had been filed in respect to that conduct, Attorney Horvath did not respond. He also did not respond to a subsequent letter from the Board reminding him of his duty to cooperate in the investigation and requesting a prompt response to the grievance. Ultimately, Attorney Horvath admitted to the Board that he had lied to the insurer's attorney and representative about having collected on the judgment and that he failed to pursue the matter.
¶ 7. The parties stipulated that Attorney Horvath's failure to promptly comply with the client's reasonable requests for information violated SCR 20:1.4(a) and his failure to explain the matter to the extent reasonably necessary for the client to make informed decisions regarding his representation violated SCR 20:1.4(b).2 His failure to act with reasonable *682diligence and promptness violated SCR 20:1.3,3 and his misrepresentations to the client regarding collection of the judgment constituted conduct involving dishonesty, fraud, deceit or misrepresentation, in violation of SCR 20:8.4(c).4 His failure to cooperate in the investigation violated SCR 21.03(4),5 and his failure to fully and fairly disclose to the Board all facts and circumstances pertaining to the conduct under investigation violated SCR 22.07(2).6
*683¶ 8. The records of Attorney Horvath's trust account that the Board had subpoenaed disclosed that the trust account was not one in which interest accruing to it was paid to the Wisconsin Trust Account Foundation, Inc., as required by SCR 20:1.15(c)(l)b.7 Also, while the checks for that account identified it as the "Paul R. Horvath Trust Account," the statements for the account showed the title to be "Paul R. Horvath, Custodian; Cory S. Horvath, Minor [his daughter]." Attorney Horvath repeatedly deposited client funds into that custodian account, in violation of SCR 20:1.15(a) and (c).8
*684¶ 9. As discipline for his misconduct in these matters, we impose a six-month suspension of Attorney Horvath's license to practice law, the discipline to which the parties had stipulated. Under the rules of this court, SCR 22.28(3),9 Attorney Horvath will be required to demonstrate his fitness to represent others in the legal system in order that his license to do so be reinstated.
¶ 10. It Is Ordered that the license of Paul R. Horvath to practice law in Wisconsin is suspended for a period of six months, commencing November 3,1997.
¶ 11. It Is Further Ordered that within 60 days of the date of this order Paul R. Horvath pay to the Board of Attorneys Professional Responsibility any costs of this proceeding that may have been incurred by the Board, provided that if the costs are not paid within the time specified and absent a showing to this court of his inability to pay the costs within that time, the license of Paul R. Horvath to practice law in Wisconsin shall remain suspended until further order of the court.
¶ 12. It Is Further Ordered that Paul R. Horvath comply with the provisions of SCR 22.26 con*685cerning the duties of a person whose license to practice law in Wisconsin has been suspended.
