Comment:
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 which is the property of a client or a third person should be kept separate from the lawyer's business and personal property and, if funds, should be kept in one or more trust accounts. Separate trust accounts may be warranted when administering estate funds or acting in similar fiduciary capacities.
Lawyers often receive from third persons funds from which the lawyer's fee will be paid. If there is risk that the client may divert the funds without paying the fee, the lawyer is not required to remit the portion from which the fee is to be paid. However, a lawyer may not hold funds to coerce a client into accepting the lawyer's contention. The disputed portion of the funds should be kept in trust 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.
A third person, such as a client's creditors, may have a just claim against funds or other property in a lawyer's custody. A lawyer may have a duty under applicable law to protect such a third-party claim against wrongful interference by the client, and accordingly may refuse to surrender the property to the client. However, a lawyer should not unilaterally assume to arbitrate a dispute between the client and the third person.
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 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.
