Interests of a Lawyer That May Affect His Judgment
The possibility of an adverse effect upon the exercise of free judgment by a lawyer on behalf of his client during litigation generally makes it undesirable for the lawyer to acquire a proprietary interest in the cause of litigation. However, it is not improper for a lawyer to protect his right to collect a fee for his services by the assertion of legally permissible liens, even though by doing so he may acquire an interest in the outcome of litigation. Although a contingent fee arrangement gives a lawyer a financial interest in the outcome of litigation, a reasonable contingent fee is permissible in civil cases because it may be the only means by which a layman can obtain the services of a lawyer of his choice. But a lawyer, because he is in a better position to evaluate a cause of action, should enter into a contingent fee arrangement only in those instances where the arrangement will be beneficial to the client.
