Validations will apply even if you are saving via a visualforce controller.

If you want to display an input on a VF page as required (even though the field is not defined as required in the schema), you can do as follows:

The bit of markup I showed you only displays the red line; it does no validation.

See here (http://salesforce.stackexchange.com/questions/22571/how-to-write-validation-in-visualforce/22635) for an example of writing validation in VisualForce page controller.

Hi,

If you are using custom controller .
Hope it will work for you.

Page:
-------------------
<apex:page showHeader="false" sidebar="false" controller="savecontroller">
<apex:form >
<html>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
    $(document).ready(function(){
        $('[id$=btn]').click(function(){
            if($('#chk2').prop('checked') == false){
                alert('Please select the checkbox');
                return false;
            }
            else{
                Callingcontrollermetod();
            }
        });
    });
</script>
    <apex:actionFunction name="Callingcontrollermetod"  action="{!savemethod}" reRender=""/>
    Do u need ? &nbsp;  <input type="checkbox" id="chk2"/><br/>
    <apex:commandButton onclick="fn()" id="btn" value="Save"/>
</html>
</apex:form>
</apex:page>

Controller : 
---------------------
public with sharing class savecontroller {
    Public void savemethod(){
        system.debug('I am called');
    }
}

Thanks.
