Contact DVD accounting for instructions. Shouldn't cost any more than a filling fee from the county. Your name on your DVC account will also change, it has to match the deed.
Talk to member admin, I don't think you have to change the deed itself, just provide documentation as long as you don't have to add or remove other names.
There was a report of them doing it with just a letter and death certificate without changing the title. You may want to talk to member admin about this. I certainly wouldn't pay this much to do so but you could do it yourself if a deed change were needed in this situation.
