    Hi Ibrahim,

     

    You can write a validation rule like:

     

     

    ISBLANK(Owner:User.ContactId)

     

    There is a contact field on user, which is not null in case of portal users. So, you can use this in your validation rule. Please let me know if you face any problem

     

    If it helps you, don't forget to mark this as best answer, it will help other community members find the solution too.

     

    Thanks
