On condition that introduces a requirement attached to an agreement or offer.

The idea

Follow on condition that with a clause containing a subject and verb. For a future condition, normally use the present simple, while the main clause can use will. The condition can come first, followed by a comma.

Examples

  • The council will fund the garden on condition that residents maintain it.
  • Mina agreed to lend the camera on condition that it was returned by Friday.
  • On condition that the data stays private, the team may share the results.
  • The landlord offered a shorter lease on condition that we paid monthly.
  • You can use the hall on condition that you leave it clean.
  • The publisher will extend the deadline on condition that the author sends a draft today.

Watch out

Do not normally use will in the condition clause to express a future requirement: write on condition that she pays, not on condition that she will pay.
