Quite frequently, entrepreneurs who seek your services to organize their company or otherwise will ask if they can pay your fees in ownership interests rather than in money. This is not because they don’t think you are worth it but rather because they need to use cash for other start-up expenses, such as marketing, etc. While it may help out your client if you accept an ownership interest in lieu of cash payment for fees, some legal and ethical concerns arise. If an attorney accepts an ownership interest, the attorney now has a dual relationship with the client: one of attorney and one of owner. Does this create a conflict, i.e., will the attorney be materially limited by their financial interest? How does an attorney sell their interest? Will the client be offended when/if the attorney sells the interest?
A look at Rule 1.8 “Current Clients: Specific Rules” is a great place to start. Not only does it help us navigate our question, but it has been copied verbatim by a majority of the states, including Pennsylvania.
Rule 1.8: Current Clients: Specific Rules
(a) A lawyer shall not enter into a business transaction with a client or knowingly acquire an ownership, possessory, security or other pecuniary interest adverse to a client unless:
(1) the transaction and terms on which the lawyer acquires the interest are fair and reasonable to the client and are fully disclosed and transmitted in writing in a manner that can be reasonably understood by the client;
(2) the client is advised in writing of the desirability of seeking and is given a reasonable opportunity to seek the advice of independent legal counsel on the transaction; and
(3) the client gives informed consent, in a writing signed by the client, to the essential terms of the transaction and the lawyer’s role in the transaction, including whether the lawyer is representing the client in the transaction.
To fully understand the details and purpose of Rule 1.8, one must consult the Comments under “Business Transactions between Client and Lawyer”

Business Transactions between Client and Lawyer
 A lawyer's legal skill and training, together with the relationship of trust and confidence between lawyer and client, create the possibility of overreaching when the lawyer participates in a business, property or financial transaction with a client, for example, a loan or sales transaction or a lawyer investment on behalf of a client. The requirements of paragraph (a) must be met even when the transaction is not closely related to the subject matter of the representation, as when a lawyer drafting a will for a client learns that the client needs money for unrelated expenses and offers to make a loan to the client. The Rule applies to lawyers engaged in the sale of goods or services related to the practice of law, for example, the sale of title insurance or investment services to existing clients of the lawyer's legal practice. See Rule 5.7. It also applies to lawyers purchasing property from estates they represent. It does not apply to ordinary fee arrangements between client and lawyer, which are governed by Rule 1.5, although its requirements must be met when the lawyer accepts an interest in the client's business or other nonmonetary property as payment of all or part of a fee. In addition, the Rule does not apply to standard commercial transactions between the lawyer and the client for products or services that the client generally markets to others, for example, banking or brokerage services, medical services, products manufactured or distributed by the client, and utilities' services. In such transactions, the lawyer has no advantage in dealing with the client, and the restrictions in paragraph (a) are unnecessary and impracticable.
 Paragraph (a)(1) requires that the transaction itself be fair to the client and that its essential terms be communicated to the client, in writing, in a manner that can be reasonably understood. Paragraph (a)(2) requires that the client also be advised, in writing, of the desirability of seeking the advice of independent legal counsel. It also requires that the client be given a reasonable opportunity to obtain such advice. Paragraph (a)(3) requires that the lawyer obtain the client's informed consent, in a writing signed by the client, both to the essential terms of the transaction and to the lawyer's role. When necessary, the lawyer should discuss both the material risks of the proposed transaction, including any risk presented by the lawyer's involvement, and the existence of reasonably available alternatives and should explain why the advice of independent legal counsel is desirable. See Rule 1.0(e) (definition of informed consent).
 The risk to a client is greatest when the client expects the lawyer to represent the client in the transaction itself or when the lawyer's financial interest otherwise poses a significant risk that the lawyer's representation of the client will be materially limited by the lawyer's financial interest in the transaction. Here the lawyer's role requires that the lawyer must comply, not only with the requirements of paragraph (a), but also with the requirements of Rule 1.7. Under that Rule, the lawyer must disclose the risks associated with the lawyer's dual role as both legal adviser and participant in the transaction, such as the risk that the lawyer will structure the transaction or give legal advice in a way that favors the lawyer's interests at the expense of the client. Moreover, the lawyer must obtain the client's informed consent. In some cases, the lawyer's interest may be such that Rule 1.7 will preclude the lawyer from seeking the client's consent to the transaction.
 If the client is independently represented in the transaction, paragraph (a)(2) of this Rule is inapplicable, and the paragraph (a)(1) requirement for full disclosure is satisfied either by a written disclosure by the lawyer involved in the transaction or by the client's independent counsel. The fact that the client was independently represented in the transaction is relevant in determining whether the agreement was fair and reasonable to the client as paragraph (a)(1) further requires.
