A lawyer should hold property of others with the care required of a professional fiduciary. Securities should be kept in a safe deposit box, except when some other form of safekeeping is warranted by special circumstances. All property that is the property of clients or third persons, including prospective clients, must be kept separate from the lawyer's business and personal property and, if monies, in one or more trust accounts. Separate trust accounts may be warranted when administering estate monies or acting in similar fiduciary capacities. A lawyer should maintain on a current basis books and records in accordance with generally accepted accounting practice and comply with any recordkeeping rules established by law or court order. See, e.g., Model Rules for Client Trust Account Records.
 While normally it is impermissible to commingle the lawyer's own funds with client funds, paragraph (b) provides that it is permissible when necessary to pay bank service charges on that account. Accurate records must be kept regarding which part of the funds are the lawyer's.
 Lawyers often receive funds from which the lawyer's fee will be paid. The lawyer is not required to remit to the client funds that the lawyer reasonably believes represent fees owed. However, a lawyer may not hold funds to coerce a client into accepting the lawyer's contention. The disputed portion of the funds must be kept in a trust account and the lawyer should suggest means for prompt resolution of the dispute, such as arbitration. The undisputed portion of the funds shall be promptly distributed.
 Paragraph (e) also recognizes that third parties may have lawful claims against specific funds or other property in a lawyer's custody, such as a client's creditor who has a lien on funds recovered in a personal injury action. A lawyer may have a duty under applicable law to protect such third-party claims against wrongful interference by the client. In such cases, when the third-party claim is not frivolous under applicable law, the lawyer must refuse to surrender the property to the client until the claims are resolved. A lawyer should not unilaterally assume to arbitrate a dispute between the client and the third party, but, when there are substantial grounds for dispute as to the person entitled to the funds, the lawyer may file an action to have a court resolve the dispute.
 The obligations of a lawyer under this Rule are independent of those arising from activity other than rendering legal services. For example, a lawyer who serves only as an escrow agent is governed by the applicable law relating to fiduciaries even though the lawyer does not render legal services in the transaction and is not governed by this Rule.
 A lawyers' fund for client protection provides a means through the collective efforts of the bar to reimburse persons who have lost money or property as a result of dishonest conduct of a lawyer. Where such a fund has been established, a lawyer must participate where it is mandatory, and, even when it is voluntary, the lawyer should participate.
