Why clearance exists
The same insured is often submitted by more than one broker. Markets generally work with the first broker to clear unless the insured names another in a broker of record letter, so clearance spares them double work and broker disputes.
What is checked
Clearance matches the insured's name and address, sometimes with other identifiers, against existing submissions, quotes and policies. Name variations, subsidiaries and changed addresses make this harder than it sounds, so it often stays manual.
Clearance and appetite
Many markets combine clearance with a first appetite check, declining risks outside their classes, territories or limits before an underwriter spends any time on them.
Where automation helps
Automated clearance fuzzy-matches names and addresses using the rules the market's team already follows, holding possible conflicts for a person to decide. Sitting at the start of intake, it is one of the first places automation gives underwriters time back.
