Short answer. Barter, or exchange, is a contract where each party gives a thing instead of money. The Civil Code defines it in Article 1638, and because it works like a double sale, the law on sales governs barter in almost everything the parties did not spell out themselves.
What the law says
By the contract of barter or exchange one of the parties binds himself to give one thing in consideration of the other's promise to give another thing.

What makes an agreement a barter and not a sale
The dividing line is simple: in a sale, one side pays money; in a barter, both sides give a thing. Article 1638 of the Civil Code puts it as each party binding himself to give one thing in consideration of the other's promise to give another. Swapping a motorcycle for a parcel of land, trading livestock for construction materials, or exchanging one lot for another are all barters. Mixed deals are common in practice — a car plus cash for a lot — and there the label depends on which part predominates. That classification is not cosmetic. It decides which rules fill the gaps when the deal later sours.
Which rules actually govern it
The Civil Code devotes only a handful of articles to barter, and then borrows. Everything the barter provisions do not cover is governed by the law on sales. That means the rules you would expect in a sale carry over: each party is treated as both a seller and a buyer of what he hands over, each warrants that he owns what he gives and that it is free from hidden defects, and each is answerable for eviction if the other is later deprived of the thing by a better title. Delivery, not the handshake, transfers ownership. So does registration, where the thing exchanged is registered land.
Where barter goes wrong in practice
Most disputes start with title, not with the swap itself. If one party turns out not to own the thing he gave, or the property is mortgaged, encumbered or covered by somebody else's certificate, the aggrieved party is not left without recourse — the warranty rules borrowed from sales allow him to recover what he parted with, or its value, plus damages. Barters of land carry the extra trap that an unregistered exchange binds only the parties, not third persons who later deal with the registered owner. And an exchange of immovables that is not in a public document is difficult to enforce and impossible to register.
Practical points before you swap
Put the exchange in writing, describe both things precisely, and state who bears taxes, transfer fees and delivery costs — the Code will not supply terms you never agreed on. For real property, insist on seeing the original certificate of title and have the deed notarised, because registration follows the deed. Barter is not a way around tax: an exchange of property is still a taxable disposition. This page is general legal information, not advice about your own transaction. If a swap has already gone bad, or you are about to sign one involving land, you can book a consultation to have the documents reviewed.
