Claiming Medical Expenses paid as part of divorce agreement to ex-wife.

I am divorced and as part of the settlement agreement, I pay my ex-wife's Medical Aid premium over to her. She belong to a registered medical aid in SA. I also refund her medical expenses to her which the medical aid does not cover. Can I claim her the amount of medical expenses that I pay to her on my tax return. My ex-wife does not claim her Medical Expenses.

Yes you can claim as this is your responsibility and she is financially dependent on your for this.
