Answer 1

Try using a different repeat var name.

Your Visualforce:

<apex:repeat value="{!lstVerifierWrapper}" var="verifier">
          <apex:pageBlockSection columns="1" id="pbsVerifierOfficerInfo" title="Verifying Officer Details">
                   <apex:inputField value="{!verifier.ver.Name}" />
                   <apex:inputField value="{!verifier.ver.Title__c}" />

In your apex constructure:

verifier = new Verifier__c();

I can't make out where that variable is declared, but I believe you have declared it as class variable and your Visualforce is trying to access that rather than the repeat var.

(could be wrong but this is the first thing that I think could be the issue)
