The short answer

Passar a perna em alguém means to cheat, deceive, or take advantage of a person. It is a negative expression and can describe dishonest business, betrayal, or someone breaking an agreement for personal gain.

Recognize the expression for dishonest treatment

It does not refer to a literal leg in its idiomatic use. The person introduced with em is the one who was treated unfairly.

O vendedor passou a perna em vários clientes.

The seller cheated several customers.

Achei que o acordo era justo, mas ele passou a perna em mim.

I thought the deal was fair, but he took advantage of me.

Não quero que ninguém passe a perna na minha família.

I don’t want anyone to cheat my family.

Describe the conduct precisely

Because the phrase accuses someone of dishonesty, use it only when the facts support that judgment. If you mean a mistake or misunderstanding, say houve um engano (there was a mistake) or não cumpriu o combinado (did not keep the agreement).

In formal communication, describe the specific action, date, or amount rather than relying on an idiom. Clear details make it easier to resolve a dispute.

O valor cobrado foi diferente do que combinamos.

The amount charged was different from what we agreed.

Acho que houve um mal-entendido sobre o pagamento.

I think there was a misunderstanding about the payment.

Ele passou a perna no sócio e escondeu as despesas.

He cheated his business partner and hid the expenses.

Put it into practice

Passar a perna em alguém is a strong informal accusation of cheating or taking advantage. Use precise facts and neutral language when you are still clarifying what happened.
