Promissory contract deposit (sinal): if the seller fails, the buyer can claim double#
Termination and refund, Delay penalty
In a Portuguese promissory contract (contrato-promessa) with a deposit (sinal), if the buyer fails the seller keeps the deposit; if the seller fails, the buyer can demand double what was paid. The buyer can instead ask a court to enforce the sale.
Se quem constitui o sinal deixar de cumprir a obrigação por causa que lhe seja imputável, tem o outro contraente a faculdade de fazer sua a coisa entregue; se o não cumprimento do contrato for devido a este último, tem aquele a faculdade de exigir o dobro do que prestouTranslation: If the party who gave the deposit fails to perform for a reason attributable to them, the other party may keep what was given; if the failure is due to the latter, the former may demand double what they paid
