Strict conditions (siempre y cuando)

When negotiating a contract or setting boundaries for a freelance gig, you often need to state firm requirements using phrases like "as long as" or "provided that."

In Spanish, you can use these three common strict conditional phrases:

  • siempre y cuando
  • con tal de que
  • siempre que

Because these phrases set up a strict condition that must be met for the main action to happen, they trigger the subjunctive.

I accept the project as long as we modify the fee.
Acepto el proyecto siempre y cuando modifiquemos la tarifa.
The rate is fine provided that you pay an advance.
La tarifa está bien con tal de que pagues un anticipo.

Notice how the verbs immediately following the conditions—modifiquemos (we modify) and pagues (you pay)—are in the present subjunctive.

I do the work provided that the payment is in advance.
Hago el trabajo siempre que el pago sea adelantado.
You can modify the design provided that it is a quick revision.
Puedes modificar el diseño con tal de que sea una revisión rápida.

You can use these phrases interchangeably to lay down your terms, whether you are asking for an advance payment (un anticipo), negotiating a fee (la tarifa), or requiring a remote position.

We accept the contract as long as the position is remote.
Aceptamos el contrato siempre y cuando el puesto sea remoto.
