Here is a common trope in movies and series: Romeo and Juliette love each other, to the great displeasure of Mr. Capulet, Juliet's father. The man decides to privately meet Romeo and to offer him big money if he accept to quit his daughter. Depending on the story, then two scenarios are possible:
- Romeo is not the good man that Juliet believes she loves, and will not refuse easy money. He disappears from Juliet's life whose heart is broken forever (or until the next love interest).
- On the contrary, Romeo abhorres the idea of living far from Juliet and refuses the money. It starts from that moment a strong enmity between the two men.
There is a third scenario that never occurs in fiction: Romeo accepts the money, but tells everything to his significant other. He uses the money to offer a happy life to Juliet. This is how I would probably act in such a situation: sure, lying to Mr. Capulet is not very honorable, but why should I act with honor with someone able of this kind of vileness?
My question: could Romeo be legally binded to honor his word and quit Juliet? Would it change something if Mr. Capulet had the idea of making Romeo to sign a written document?
For the sake of the question, we can assume that it happens in the US (since it is a regular trope in US TV shows). Answers that compare situations in other countries is interesting too.
