A public defender doubles as a private dominatrix to support her family, but when a lonely, corrupt judge finds out she must sexually and emotionally satisfy a man with the power to ruin her life.

Fantastic premise. So much potential but if she is a dominatrix why would she be averse to dominating the judge?

remove 'lonely' and it might work better

An interesting setup. But,.. what's her dramatic problem?? As long as she gives him what he wants -- no problem, right?

Further if he avails himself of her kinky services, then she can blackmail or expose him.?? She likewise can ruin his life.

So as I was saying, what's her dramatic problem?

Also, the logline overlooks the most interesting aspect, the story hook:? their relationship.? In the courtroom, he dominates her.? In the backroom, she dominates him.
