The contract comes into effect with the club's confirmation; the right to play arises upon receipt of full payment.
§ 4 End of subscription. The subscription ends automatically at the end of the season. It does not renew and needs no termination.

§ 9 Severability. Should any provision of this contract be or become invalid, the remaining provisions remain in effect.
1. General. On entering the dome these rules apply to tenants, partners and guests. The dome may only be used during opening hours and for tennis. Sportswear and clean tennis shoes suitable for artificial turf are mandatory. Do not leave valuables in the changing rooms; the club is not liable for losses. Smoking is prohibited throughout the dome. Emergency contacts are posted in the dome and listed in the contact section of this page.
2. Playing time. The dome is open daily from 7 am to 10 pm. An hour starts on the hour and lasts 60 minutes; the court must be vacated on time. Players brush the court after playing; brushing is part of the booked hour so that the court is free on the hour. The club may change allocated court numbers for operational reasons.
3. Bookings. Winter subscriptions are handled via this online form. Individual free hours are allocated through the booking channels offered by the club.
4. Coaching. Coaching is possible on all three courts. Coaching in the dome is provided exclusively by the Karahan Tennis Academy, authorised by the club. Coaching by other persons is not permitted.
5. Noise. Sound carries in an air dome. Please keep the volume reasonable so that players on neighbouring courts can concentrate.
6. House rules and liability. The board and persons authorised by it exercise the house rules. The club's liability for accidents, losses and personal, property or financial damage inside and outside the dome is excluded to the extent permitted by law. Tenants bring only partners and guests who accept these rules.
7. Violations. Violations of the hall rules may lead to exclusion from use and a ban from the premises. The obligation to pay the subscription remains; unused hours are not refunded.
