Short answer. Possibly. Receiving a share of the profits is prima facie evidence of being a partner, and no writing is needed to create one. But the presumption is rebuttable, and the Code lists payments that never raise it — wages, rent, interest on a loan, a debt paid by instalments.

What the law says

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, but no such inference shall be drawn if such profits were received in payment:

Civil Code, Article 1769 — Rules to Determine Existence of a Partnership. Read the full provision →

A partnership is made by agreement, not by paperwork

Art. 1767 asks only that two or more persons bind themselves to contribute money, property or industry to a common fund with the intention of dividing the profits among themselves. Nothing there requires a signature, so an unwritten arrangement can be a partnership in full. Form comes in later and for other purposes: Art. 1771 requires a public instrument where immovable property is contributed, and Art. 1772 requires registration where the capital is three thousand pesos or more — while expressly saying that failure to comply does not affect liability to third persons.

What the profit share proves, and what rebuts it

Profit-sharing is the strongest single indicator, which is why the Code makes it prima facie evidence. Prima facie means the burden shifts, not that the question is closed. The article then names the payments that carry no such inference: profits received as a debt paid by instalments, as wages of an employee or rent to a landlord, as an annuity to the widow or representative of a deceased partner, as interest on a loan even where the amount varies with the profits, and as the price of goodwill or other property sold by instalments.

Sharing the takings is not sharing the profits

Two of the article's rules do a lot of quiet work. Co-ownership or co-possession does not by itself establish a partnership, even where the co-owners share what the property earns — so two people who inherited a building and split the rent are co-owners, not partners. And the sharing of gross returns does not establish one either. Profits are what is left after expenses, and an arrangement that divides revenue without anyone bearing the losses usually lacks the common fund and the shared risk that make a partnership.

Why the answer matters more than it sounds

Being a partner is not only a claim on the business; it is exposure. Partners can bind one another, and Art. 1816 makes them liable pro rata with all their property for partnership obligations after the assets are exhausted. So the person insisting there was no partnership is often the one being asked to pay somebody else's debt. The facts that decide it are ordinary ones: who put in what, who bore the losses, who dealt with suppliers, how the money moved, and what the two of you told other people the arrangement was.
