In the United States, there is no regulation as far as I
know that dictates what seat the Pilot In Command must
utilize, except that it must be a control seat, which I
take to mean a seat with controls. Nothing I am aware of
prevents a pilot from flying solo in the right seat, the
front seat, the back seat, or even a passenger seat (with
strings attached to the yoke).

Some aircraft have such limitations. The aircraft I usually fly
(BH412 and SK76) limit solo flight (or flight with one pilot) to
the right seat. If such a requirement is in the flight manual
limitations section, it's a legal requirement.
