@Html.Action("Create", "RequestorInformation")
@Html.Action("Create", "UserInformation")

@using (Html.BeginForm("Create", "RequestorInformation", new { id = "formRequestorInformation" })) { 
@Html.ValidationSummary(true)

@using (Html.BeginForm("Create", "UserInformation", new { id = "formUserInformation" })) { 
@Html.ValidationSummary(true)

@using (Html.BeginForm("Create", "SSAR", new { id = "formSSAR" })) {

    $('form').each(function (formIndex, formElement) {
        var f = $(formElement);
        alert('formIndex: ' + formIndex);
        if ($(this).validate()) {
            $.post(f.attr('action'), f.serialize(), successfulFormPost)
        }
    });

$("#SubmitForm").click(function (event) {
    event.preventDefault();
    $('formRequestorInformation').validate();
    if ($('formRequestorInformation').valid()) {
        alert('Requestor Form Is Valid!!');
    }
});
