Short answer. Toward mortgage. Article 1603 of the Civil Code says that in case of doubt, a contract purporting to be a sale with right to repurchase shall be construed as an equitable mortgage. Genuine ambiguity is resolved against treating the transaction as a completed sale.

Why doubt is resolved this way
Article 1603 sets a default rule for genuinely uncertain cases: in case of doubt, a contract purporting to be a sale with right to repurchase shall be construed as an equitable mortgage. This means that where the evidence does not clearly establish which the parties intended, a true sale or a disguised loan secured by the property, the law does not leave the question evenly balanced; it tips the scale toward the interpretation that favors the seller retaining substantive protections as a debtor rather than having permanently lost the property.
Why the law leans this direction rather than the other way
This rule reflects a protective policy toward sellers under pacto de retro arrangements, who are often in a weaker bargaining position and may end up signing what looks like a sale when what they actually needed was a loan. Treating a genuinely doubtful transaction as an equitable mortgage protects against the risk that a seller loses property outright over what was, in substance, meant to be temporary security for a debt, rather than an actual transfer of ownership to the buyer.
How this connects to the specific presumptions elsewhere in the law
Article 1603's general rule for doubtful cases works alongside the more specific circumstances the Civil Code lists as triggering a presumption of equitable mortgage, such as an unusually low price or the seller remaining in possession. Even where none of those specific circumstances squarely applies, Article 1603 still directs that genuine doubt about the transaction's real character be resolved in favor of finding a mortgage, rather than requiring one of the specifically listed circumstances to be present before the seller gets any benefit of the doubt.
What this means if your own transaction is ambiguous
If the true nature of your transaction is genuinely unclear from the contract and the surrounding circumstances, Article 1603 means that ambiguity works in your favor if you are the seller trying to establish that the arrangement was really a mortgage. This does not eliminate the need to present evidence about what actually happened and what the parties intended; it means that once real doubt exists after considering that evidence, the law resolves it toward the equitable mortgage interpretation rather than toward an outright sale.
