The deceased’s spouse, parents, child (if age 21 or older), or donee/deputy can sign the form at the hospital within two weeks of the member’s demise. This should be done as soon as possible, as hospitals have to submit a MediSave claim before the member’s CPF savings are distributed.
If there’s no immediate family or donee/deputy, other relatives of the deceased can sign the MCAF, with the approval of the Ministry of Health. The hospital can help you obtain this approval.
