What is typically NOT a basis for an insurer's pre-settlement payments to a claimant?

A waiver of further claims typically implies that the claimant agrees to forgo any future claims related to the incident in question, which can sometimes be a condition for receiving a pre-settlement payment. Similarly, documentation of damages is crucial for the insurer to assess the claim's validity and is hence generally considered a basis for any pre-settlement payment.

In contrast, a release of all claims is more formal and thorough than what is typically required for a pre-settlement payment. Instead of a comprehensive release, insurers might make pre-settlement payments based on preliminary assessments without binding the claimant to relinquish all rights to future claims related to the incident. The idea here is that pre-settlement payments are often made to provide immediate assistance to the claimant, while a full release of claims would usually entail more extensive negotiations and a firmer commitment from the claimant regarding future claims, which may not be the case at the point of pre-settlement.

Thus, a release of all claims does not align with the nature of typical pre-settlement payments, making it the most accurate choice among the options presented.
