Short answer. No. Under Article 1470 of the Civil Code, a grossly inadequate price does not by itself void a sale. The contract remains valid unless the low price reveals a defect in consent — such as fraud, mistake, or undue influence — or shows the parties intended a donation rather than a sale.
What the law says
Gross inadequacy of price does not affect a contract of sale, except as it may indicate a defect in the consent, or that the parties really intended a donation or some other act or contract.

The general rule: price alone does not void a sale
Philippine law does not require a price to be fair to make a sale valid. A seller who freely agrees to accept far less than market value for property has made a lawful sale. Article 1470 of the Civil Code is clear: gross inadequacy of price does not affect a contract of sale. The parties' freedom to set the price they choose is respected, even if outsiders — or one party later — consider it a bad deal.
When a low price can become a legal problem
Article 1470 carves out two exceptions. First, a shockingly low price may be evidence of a defect in consent — fraud, mistake, or undue influence that prevented a party from genuinely agreeing. If the price was so low that no reasonable person would have accepted it freely, a court may examine whether the seller was deceived, pressured, or confused. The price itself is not the defect, but it can be a powerful indicator that something was wrong at the time of signing.
When the sale is really a donation in disguise
The second exception addresses disguised transactions. Sometimes parties dress up a donation as a sale — perhaps to avoid inheritance rules or gift taxes — by writing an absurdly low price into the deed. Article 1470 allows a court to look past the label. If the evidence shows the parties never really intended an exchange for value, the transaction will be treated for what it actually is — a donation — and the stricter requirements for donations will apply instead.
What this means if you are in this situation
If you signed a sale at a price you now regret, the inadequacy of that price on its own is unlikely to undo the contract. Your case, if any, will rest on proving that you did not consent freely — that you were misled, pressured, or that you and the other party actually intended something other than a genuine sale. The facts around how the deal was negotiated, what you were told, and what both parties actually understood matter far more than the price gap itself.
