How to bind multiple forms validation to Jquery Validator

I have multiple forms in my page which has same values.

Instead of writing multiple rules and messages, I have written a common method where rules and messages can be pass as a parameter.

But this works only if a page has different form values. And if a page has multiple forms with similar values then am unable to bind it, because I don't want to write multiple rules and messages. Because both the forms has to display the same error messages, if the validation fails.

So in the below code, both the rules and messages are same, how do I can use one set of rules and messages to display for both the forms accordingly.

This is what I tried.

HTML:

<form id="form1">
  <label for="firstName1">First Name </label>
  <input id="firstName1" name="firstName1" required/>
  <label for="lastName1">Last Name </label>
  <input id="lastName1" name="lastName1" required/>
</form>

<form id="form2">
  <label for="firstName2">First Name </label>
  <input id="firstName2" name="firstName2" required/>
  <label for="lastName2">Last Name </label>
  <input id="lastName2" name="lastName2" required/>
</form>

JS:

Validation Common Method:

window.validation = {
   validateForm : function(that, fId, rules, messages, handlerFnc){
    var _self = this, _this = that;
    return {
      rules : rules,
      messages : messages,
      submitHandler: function(fId, evt) {
        var serForm = $(fId).serialize();
        (handlerFnc) ? handlerFnc(fId, _this, evt) : null;
      }
    }
  }
}

Calling this method in my View:

    var rules = {}; var messages = {};
          rules.firstName1 =  {
            required: "FN Req Field"
          };
          messages.lastName1 = {
            required: "LN required field"
          };
          rules.firstName2 =  {
            required: "FN Req Field"
          };
          messages.lastName2 = {
            required: "LN required field"
          };
          $('#form1').validate(validation.validateForm(_self, "form1", rules, messages, _self.handlerFn2));
          $('#form2').validate(validation.validateForm(_self, "form2", rules, messages, _self.handlerFn2));
