Self Directed IRA Fees?

[Dennis Walker]

I have an SDIRA. My Custodian is telling me that I can pay their fees with funds from outside my IRA. Is that right? I know there are other fees and expenses that I have to pay with funds from inside my IRA.  So now I'm confused as to when do I need to use funds from inside my IRA and when can I use funds from outside of it? Can someone explain this to me?

Thanks
