See more: MVC validation
[Required(ErrorMessage = "Confirmed is required")]
       [Display(Name = "Confirmed")]
       public Boolean Confirmed { get; set; }
       
       [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}")]       
       //[Required(ErrorMessage = "Confirmed Date is required")]
       [Display(Name = "Confirmed Date")]
       public DateTime ConfirmedDate { get; set; }

Above are two fields in my Model.
I just want to validate the ConfirmedDate when Confirmed CheckBox is checked, when it is unchecked
the ConfiredDate is not required.

Can anyone give an example or suggestion ?

The typical way to accomplish this would be to execute the validation in the setter for Confirmed:
private Boolean _Confirmed;
[Required(ErrorMessage = "Confirmed is required")]
[Display(Name = "Confirmed")]
public Boolean Confirmed
{
  get { return _Confirmed; } 
  set
  {
    if (value != _Confirmed)
    {
      _Confirmed = value;
      if (_Confirmed)
      {
        // here you validate ConfirmedDate
      }
    }
  }
}
