A thread I recently read made me think about the validity of Ukyo's engagement. The way I see it this engagement can be considered invalid in a number of ways.
First I'll start with the simplest, Ranma's dad claimed that he told Ukyo's dad that Ranma was already engaged. Therefore Ukyo's dad knew ranma was unable to be engaged with someone else and pushed it on Genma anyways. Of course we only have Genma's word on this.
Second possible way that this engagement can be considered invalid. Ukyo had put up her dowry in a bet and lost it (doesn't matter if the person was cheating).
Third if this was a modern Omiai, as it appears to have been the people involved get a say as to whether they will marry the person or not (in a traditional omiai they are generally married at their first or second meeting with no say in the matter). If Genma really did ask Ranma which he preferred Ukyo or that food item Ukyo always makes which name I can't recall at the moment and Ranma really did choose the food over Ukyo it can be considered as ranma vetoing the Omiai. If Gemna really didn't ask Ranma that since Ranma can't remember the incident in question the only real reason he would have for making that story up besides making Ranma look bad is to cover his own ass. Though it is entirely possible that Ukyo and her father saw it as a traditional Omiai and not a modern one.
Fourth Ukyo gave up her claim on the engagement instead she wanted revenge. When she defeated Genma she even stated that she wasn't there to marry Ranma she wanted revenge. The fact that Genma took the beating instead of running away or defeating Ukyo (both would be in character for him) is also telling. Since she defeated Genma and got her revenge her honor would of been restored all Ranma had to do was let Ukyo defeat him and then get on with her life. Ukyo would have seen it as having her honor fully restored and would have gone home.
The fact that Ranma's dad stole her dowry does not validate the engagement all it does is show that Genma is a thief and it was more a crime of opportunity then planned out. (pretend to go along with it to get the cart then run no real planning and probably figured that Ukyo's dad would just call the police and forget the entire thing about an engagement since it would be to much of an embarrassment to admit that he was going to engage his daughter to a thief)
What does validate the engagement is Ranma calling her his fiancee and no one stating straight out that the engagement isn't valid but Genma did leave himself a way out. Ranma probably does consider it valid as well as most of the cast. Amazons probably don't care one way or another, most of the cast were not told all the details only knowing that Genma engaged Ranma to her, Ranma's mom probably doesn't see a problem (marry Akane and take all the rest as mistress's is probably her line of thinking). The only one who seems to know that it isn't valid is Genma and he doesn't seem to want to do anything about it instead leaving it all to Ranma.
