Hi,

responsibility is a strong word. 'Technically' your T isn't responsible for filling out the paperwork but if they said they would then it would be the right thing to do on their part. Also as the professional who has been seeing your for a significant period of time, they would be most appropriate person to fill out the paperwork if it asks about your mental health.

I don't know the full story of the relationship between you and the T or how it ended but if it was amicable I would say that you should make an attempt to ask her/him if they are still willing to do it and if not to also let you know.

You have only ended a few weeks ago so I think your T should do this for you. Caring shouldn't end the second you leave.

If you seen your therapist privately it is possible that they could ask for a fee for form filling.
