> Basically a technically competent will executor.
I don't think OP is saying that an attorney *can't* get these things done, but that it would make them feel more comfortable knowing that a technically competent person and/or service will be performing the actual actions.
I do think there's a place for an attorney here, in the sense that they could be the trusted individual responsible for notifying DeadManService, Inc. that a particular person has, indeed, passed on and wishes DeadManService to run their instructions.
I'm not sure what value adding a DeadManService would have then. Probably simpler to just have the attorney's instructions say, "Hire a technical consultant to carry out the following:".
