Contract Clauses Every Buyer Should Review Before Signing a Purchase Agreement

The contract most people sign too quickly

The purchase agreement, or the private contract that formalizes it, tends to be treated as a bureaucratic step between the negotiation and the deed. In practice, it's the document that already determines what happens if something goes wrong: financing falls through, a hidden defect turns up in the property, or delivery is delayed. Reviewing these clauses before signing is the moment when terms can still be negotiated; afterward, they already carry legal effect.

Condition precedent clause

Defines whether the contract's validity depends on a future event, such as loan approval or the completion of due diligence. Without this clause properly drafted, the buyer could remain contractually bound to complete the purchase even if financing is denied.

Penalty and termination clauses

Sets the amount owed if either party withdraws. It's essential to check whether the percentage is symmetrical between buyer and seller, and whether it distinguishes withdrawal without cause from termination due to the other party's breach; unequal treatment in this clause usually signals a contract drafted one-sidedly in the seller's favor.

Clause on debts and liens prior to the sale

Should explicitly state that property tax, condominium fees, and any liens predating the sale are the seller's responsibility, rather than simply assuming it. Contracts silent on this point tend to generate disputes exactly when an old debt surfaces after registration.

Possession delivery clause

Defines the date and conditions under which the property will actually be handed over, clearly separating the date the contract is signed from the date physical possession is transferred. The absence of this distinction is a common source of conflict in purchases of properties still occupied by the seller.

Hidden defects clause

Formalizes the seller's liability for defects not apparent at the time of sale: leaks, structural issues, irregularities not caught during inspection. Contracts that generically waive this liability deserve extra scrutiny before signing.

Irrevocability and non-retraction clause

Common in purchase agreements, it makes the deal binding on both parties, preventing unilateral withdrawal without the consequences set out in the penalty clause. Its presence, or absence, substantially changes the level of commitment the signer is taking on.

Forum selection clause

Defines where any legal disputes related to the contract will be handled. For buyers based outside Ceará, or outside Brazil, this clause has a direct practical impact on the cost and feasibility of pursuing a dispute in court if it becomes necessary.

Conclusion

None of these clauses, on its own, invalidates a contract. But the absence, or the unbalanced drafting, of any one of them shifts onto the buyer a risk that could have been negotiated before signing. Reviewing the agreement with legal attention doesn't slow down the purchase; it defines exactly the terms under which it's being made.
