In determining whether a partnership exists, the following rules shall apply:

(1) Except as provided by Code Section 14-8-16 persons who are not partners as to each other are not partners as to third persons;

(2) Joint tenancy, tenancy in common, tenancy by the entireties, joint property, common property, or part ownership does not of itself establish a partnership, whether such co-owners do or do not share any profits made by the use of the property;

(3) The sharing of gross returns does not of itself establish a partnership, whether or not the persons sharing them have a joint or common right or interest in any property from which the returns are derived;

(4) The receipt by a person of a share of the profits of a business is prima-facie evidence that he is a partner in the business; provided, however, that no such inference shall be drawn if profits were received in payment of the following, even though the amount of payment varies with the profits of the business:

(A) A debt, whether by installments or otherwise;

(B) Wages, salary, or other compensation to an employee or independent contractor;

(C) Rent to a landlord;

(D) An annuity or other payment to a surviving spouse or representative of a deceased partner;

(E) Interest or other payment or charge on a loan;

(F) Consideration for the sale of good will of a business or other property, whether by installments or otherwise.
