Carer's allowance (CA) is a means-tested social assistance payment made to a person who is habitually resident in the State and who is providing full-time care and attention to a child or an adult who has such a disability that as a result they require that level of care.
If a person is in receipt of another social welfare payment in their own right (other than unemployment payments or supplementary welfare allowance) or being claimed as a qualified adult on their spouse/partner's payment, a half-rate carer's allowance can be paid too as long as all the normal conditions for receipt of CA are satisfied.
The person concerned is in receipt of one parent family payment. As a result, CA is being paid to her at half-rate.
I hope this clarifies the position for the Deputy.
