§ 60

If a rent increase is implemented, the deposit and prepaid rent may be adjusted. The adjustment for the mentioned amounts can be collected in equal monthly installments over the same number of months that the amount originally corresponded to in relation to the rent at the commencement of the tenancy. The first sentence applies correspondingly if the tenant has chosen to provide security in the form of a bank guarantee or a deposit account balance instead of a deposit. If the rent is reduced, the landlord must make a corresponding repayment of the deposit and prepaid rent to the tenant effective from the date of reduction.

Stk. 2.The adjustment of the deposit and prepaid rent according to subsection 1 is a mandatory monetary obligation in the tenancy, cf. § 182, subsection 1, no. 1. If the tenant has chosen to provide security in the form of a bank guarantee or a deposit account balance instead of a deposit, the rules for mandatory monetary obligations apply correspondingly, cf. § 182, subsection 1, no. 1.
