Think about it, if you allow the registrar (who has the ultimate obligation to pull the domain) to instead obscure their contact for a fee, then, you have essentially eliminated any such protection.
That would depend on the terms of the contract between you and the registrar. But I do agree that this would be better served by a neutral third party (who would probably charge a lot less than a lawyer would).
No matter who you go with for the service, read the fine print before you sign on the line ...
