Can I change caregiver company without a hassle if my brother requested to terminate, but has changed his mind now?

Have no idea what your question means.

You do not give us [enough] facts to make a reasonable or useful suggestion.
Let your brother handle it. Why are you involved? Enlist a social worker to help sort this out.

Gena / Touch Matters

If he had a contract, please read that contract carefully. They is key.

Tsward: It could depend on whether there exists a contractual obligation.

Sure. I am assuming there was no contract that stipulates otherwise?

I really don't understand what you are trying to say. Your brother was not happy with the agencyhe is using and wanted to terminate. Did he actually terminate this agency? Now he has changed his mind so u have no idea what to do.

If ur brother is in the last stage of COPD maybe u should get Hospice involved.

This is a CG co for your brother? If so, this is his choice, and you just have to roll with it.

Assuming he is capable of making decisions for himself. If this is a company you need to work with, it would be appropriate for him to ask you to be involved with them.

Honestly, I'm with Alva. I have no idea what you can do.

Not a clue.
Wish you luck.
