my legal experiance was limited to a years worth of lessons at school 5 years ago, but a few things i have noticed, if it really matters, substitute first names for Mr or Miss surname. Next you forgot to include operating under the influence of drugs(which i think is picked up by the cops these days) Not saying she would ever do that, but would be appropriate to add. Like i said limited legal experiance, and if this isnt meant as much more than a personal agreement it may not matter as much:)
Side note i am willing to take the chance of a shotgun pointed at me for a date

Just kidding
