Once the tenancy has begun: The termination options are regulated in your contract. For the ordinary termination by the end of the semester with contract end date February 28th or August 31st, you will receive the appropriate form from your resident manager. The deadline for this is November 30th for end date February 28th and April 30th for end date August 31st. For an extraordinary termination (“major cause”) one of the conditions regulated in the contract must be present and this must also be proven with a written evidence/confirmation. The full list of applicable scenarios is listed in your contract. The notice period here is one month and always to the end of the month. Before the tenancy starts: Once the contract is concluded, the following terms apply for cancellation: within 14 days after the signature of the contract cancellation is free of charge and eventual payments will be refunded as a whole after that until 3 months before the contract start date cancellation is possible for a fee of 150 EUR, the rest of the prepayment will be refunded after that until 1 week before the contract start date cancellation is possible for a fee of one monthly rent, the rest of the prepayment will be refunded. Only after 1 week before the contract start date, cancellation is no longer possible. For the property in Aachen the minimum contract duration is 12 months, unless a proof can be provided (an official document) that outlines that you need to stay for less time (for example an Erasmus semester or an internship with a fixed end date). In the latter case, the duration of stay can be adapted to the duration of the permanence in the city.
