destrocar

A rare, mostly legal/commercial term meaning to undo or reverse a trueque (barter or exchange) — essentially, to cancel a swap and return the original items. It's built from the same des- + trocar pattern as many other verbs in this family, but almost never appears outside specialized or historical writing.

• Las partes acordaron destrocar el intercambio original. — The parties agreed to reverse the original exchange.
• El contrato permitía destrocar el trueque si una de las partes incumplía. — The contract allowed the barter to be undone if either party defaulted.
• Rara vez se usa destrocar fuera de textos legales antiguos. — Destrocar is rarely used outside old legal texts.

Confusing destrocar with destrozar (to wreck/smash) — they look and sound similar but mean completely different things; destrocar is about undoing a trade, not breaking something.
