Can pre-nuptial agreements protect my fiance's assests from being depleted by potential lawsuits against me?

We are considering getting married and having a pre-nuptial agreement to establish and protect separate property. If (god forbid) I was to cause an accident that in which damages exceeded an umbrella policy coverage amt for myself, would the pre-nup protect my future husband's assests from being depleted to settle my claim?

My boyfriend/fiance is very protective of his assests and considers in advance any risks to it. Can a pre-nup completely protect his assests from me and anything I could be held liable for?
