Hi,I answered your question on your other post here. https://community.scope.org.uk/discussion/49692/not-been-contacted-can-they-stop-her-money#latest
The reason it's stopped is because the award had an end date not a review date. It can't continue because there's no longer a PIP award for it to continue. Did she know the end date, or didn't she realise? If she knew then i don't understand why she didn't ring DWP to ask for those forms. You say her husband is off sick, what other benefits do they claim? Does she work?
