Yes, you can make a payment covering part of the principal amount of the lease, thus reducing your monthly payment amount going forward. To do this, you must fill in an Application for an Additional Invoice (LV) (in Latvian), sign it, and send it to lizings@citadele.lv. After receiving this, Citadele Leasing will issue an additional invoice for the amount stated in your application, and will prepare a new payment schedule and send it to you.
