Insurance companies fulfil their contractual obligations in the event of a claim by reimbursing damages up to defined coverage amounts. The amount of coverage is defined in contracts, signed, scanned, and stored in various formats. These coverage amounts can change over time, however, because new laws are passed, or regulations adapted. As a result, insurance companies must revise their contracts accordingly. But they face the challenge of not knowing which contracts are actually affected by the changes. If they fail to meet the requirements, however, insurance companies can be faced with lawsuits from their customers.
