In case there are any changes that need to be made in the policy such as address change or any particular changes regarding the automobile or its usage, it could be done by an endorsement by the insurance provider. You need to submit a letter to your insurance provider along with the proof of the changes so that you could obtain the endorsement. There are few endorsements that might charge an extra premium from you.
The minimum coverage defined by German law for car liability insurance / third party personal insurance is €7,500,000 for bodily injury (damage to people), €500,000 euro for property damage and €50,000 for financial/fortune loss which is in no direct or indirect coherence with bodily injury or property damage. Insurance companies usually offer all-in/combined single limit insurances of €50,000,000 or €100,000,000 (about €141,000,000) for bodily injury, property damage and other financial/fortune loss (usually with a bodily injury coverage limitation of €8-15,000,000 for each bodily injured person).
Comprehensive insurance covers all of the above and damage to the vehicle caused by the driver themselves, as well as vandalism and other risks. This is usually the most expensive type of insurance. It is custom in the UK for insurance customers to refer to their Comprehensive Insurance as "Fully Comprehensive" or popularly, "Fully Comp". This is a tautology as the word 'Comprehensive' means full.
A compulsory car insurance scheme was first introduced in the United Kingdom with the Road Traffic Act 1930. This ensured that all vehicle owners and drivers had to be insured for their liability for injury or death to third parties whilst their vehicle was being used on a public road. Germany enacted similar legislation in 1939 called the "Act on the Implementation of Compulsory Insurance for Motor Vehicle Owners."
