Can a gravitational locked planet outside the Goldilocks zone support life on the side facing the star?

I have read that based on a stars size the Goldilocks zone will differ from star  to star.

I have also read that if a Planet has one side locked facing the star with in the Goldilocks zone it wouldn't be able to support life because it would be too hot.

So what if it is outside the Goldilocks zone but the side facing the sun has all the things needed for life.

Would the science support the possibility that life could be possible?  

Would this planet also need a moon orbiting around it to help create tidal currents on the liquid side and helping the tectonic as well?

And perhaps if the planet also needs to turn would it be possible that instead of turning in relation to the sun like our planet does but on a tilt it spins in a way that one its poles are facing the star.

Yes I have no idea what would cause a planet to rotate like that, but my question is basically can a planet outside the known habitable zone with a single side always facing the star support life and does the math allow for this?

There are multiple definitions for the habitable zone around a star, depending on various assumptions. The classical model doesn't include atmospheric effects, which obviously have a significant influence on surface temperatures. It also doesn't account for a tidally-locked planet, or the possibility of alternative types of biochemistry (meaning life based on a solvent that is not water).

All that to say, the habitable zone concept is more of a loose guideline than a precise limit on where life could exist. The planet you are describing is theoretically capable of supporting life, despite not being exactly within the habitable zone. Since we have yet to find extrasolar life, there's no validation for any version of the theory, so take it with a grain of salt. It's more of a best-guess as to where life is likely sustainable that a hard limit on where life can reside.

Regarding requiring a moon, that delves too far into speculation to be really meaningful.
