Yes Aatish. But you can get the list by extensions. Check the codes below.

Page 
<apex:page standardController="Custom_Object__c" extensions="TempDeleteController">
  <apex:repeat value="{!childContact}" var="c" >
      {!c.Name}
  </apex:repeat>
</apex:page>
Apex class 
public class TempDeleteController{
    
    public List<Contact> childContact{get; set;}
    private final Custom_Object__c co;

    public TempDeleteController( ApexPages.StandardController stdController ){
        
        this.co = (Custom_Object__c)stdController.getRecord();
	    childContact = new List<Contact>();
        
        for( Contact c: [SELECT Id,Name FROM Contact WHERE Custom_Object__c = :co.Id ] ){
            
            childContact.add(c);
        }
    }
}

Hi Aatish,

Please check the child relationship name in Contact object. (Open Lookup/Master-Detail field-There you can see Child Relationship value)

I checked with Account and Contact relationship. It is working for me.User-added image
Field is
User-added image

Check the Child Relationship Name and use that

 hi alex problem solved , actually i was trying to make standard contact object as child of custom object but when i take custom object child different custom object then its work fine for me. thanks for your help
aatish sharmaaatish sharma
yes, i just wanted to confirm with you can we make a standard object such as contact as a child of custom object, and then can get the standard object object as child in query if yes. then problem still there because i used custom object now, and its become parent and child both custom object now, but when parent is custom and child is standard then i  cant fetch the query from the soql. why?
