Hi 
Lakshmi Narasimha,

You can write trigger using before insert event.

Please see below trigger which throws an error when account already exists.
  
trigger duplicatePreventer on Account (before insert) {
   List<Account> acct= [select id, name from Account];
    for(Account a:acct)
    {
        for(Account a1:Trigger.New)
        {
            if(a.Name==a1.Name)
            {
               //a1.name.adderror('Account already exist'); 
                a1.adderror('Account already exist');
            }
                
        }
    }

}

Hope this helps you!
