Phrases such as "working age" are misleading as they do not apply to DLA claimants being invited to claim PIP.
The test is whether the claimant was under the age of 65 on 8 April 2013, if they were then they are eligible to be transferred even if they are over the age of 65 when they received the invitation.
If you wife has been invited then she must make a claim for PIP if she wishes to retain her benefit, whatever happens, her DLA claim will be closed by this process.
Please refer to our PIP Claim guide for assistance with her claim.
