What form do I need to file in order to receive reimbursement for out-of-pocket expenses & hours working as an Estate Administrator

I was an administrator for deceased dad’s estate, but had issues closing the estate, as my sibling and I couldn’t come to an agreement. We had a new attorney named as the administrator & are hoping to close the estate within the month. I would like to get reimbursed the several thousand dollars I paid for the estate, plus compensation for the many hours I spent working on the estate. I was told that I need to file a motion, but am unsure which form or how to do that, as I’m not an attorney.
