Expense compensation..?

Hello, a question concerning the compensation for loss of use after an accident, or the daily allowance claim of the victim; the accident occurred in mid-December: the victim was taken by another car, which wanted to drive from a side street, the driveway – and there was a collision; according to an independent witness and (although also) the police a “clear thing” … the victim’s car came immediately afterwards to the workshop – the same day before (group D/38 EUR) and a few days later, the report is sent to the insurance companies; the passenger car of the injured person, which is not suitable for traffic due to the damage, is still in the workshop today (11.02.) – which is mainly due to the fact that the accident causer did not see a “necessity” to send an accident report to his insurance company about 6 weeks (from the date of the accident) – however, when he did it at the last possible date, his view of the Incident completely different, so now on the part of the legal department of the insurance the “debt question” is clarified … and there will probably be the OK for repair in 1 to 2 weeks on the part of the insurance company. the claim to a replacement vehicle for which has not been asserted; for which period is the entitlement to loss of use compensation? – from workshop? – exclusively for the (coming) repair period? Greetings, v33
