I will try to keep this as brief as possible. My daughter's dad (who she didn't see) recently passed away (in August). As soon as I knew I rang the CMS to inform them. He hadn't been paying, and had accrued arrears of over 5.5k . It is now looking likely that the CMS didn't investigate this, and that any estate he had may have already been distributed , meaning the arrears owed may never be paid. Would I have cause to complain about this?
