My midwife actually didn't want to talk about birth fees, she said she hated the money part of it. I emailed her regarding the birth fee (I switched to her at 20w) and she emailed me an amount. We never talked about it again until after ds was born. At my pp visit one week after ds was born she asked me if I had the birth fee. I gave her half then and the other half a few weeks later (4w pp). I would have had the full amount at the birth, but we had a large car repair that ate up some of the money, so I had to wait for the money that I was expecting from refinancing the house. There was a delay in getting the house refinanced because someone messed up.

I felt terrible that I didn't pay her the full amount right then, but she was very understanding. I apologized over and over, but she told me she was just glad to get it at all! Seems that a lot of the time she doesn't get the full amount.
We had a verbal agreement, no paperwork at all. Midwives aren't legal in Indiana (the exception is CNM in a hospital or birthing center and there's only one BC in all of IN).
Of course, next time I will have the full amount for her at the birth (well, the pp visit anyway) even if I have to get a short-term loan. I feel she deserved that money asap because she was always available to me via phone, email, pager and cell phone.

edited to add: since we didn't didn't really discuss the money part of it I'm not sure what would have happened if I had transferred. Since I had state insurance that would cover a hospital birth, I would have wanted to go ahead and pay her. I got my money's worth in having a wonderful midwife available to me 24/7!
She did continually remind me to call her asap because my first birth was only 8 hrs from start of pitocin IV to birth and we knew it could go fast. I had ds four hours after I decided maybe it was the real thing and called the midwife. Three hours after she arrived.
