Answer:
It's revoked and the money is for Frank
Step-by-step explanation:
A causa mortis is called a deathbed gift. It's given when one party is approaching death. If they do not die the gift is not to be given and if the party is still alive the gift can be revoked.
The premise of the gift was under the impression that it would belong to bubbles if, in fact, Frank did not make it. Clearly meaning, Frank is giving the money to Bubbles in the event that he dies.
Franks was not clear on the stipulations of the agreement if he were to live. This is where the exact terms of agreement was unclear.
Bubbles also was not honest and did not uphold her part of the agreement by not getting a new boyfriend. She also did not clarify the terms and conditions of what would happen if Frank were to live.
Since both parties were not completely of sound understanding the only way to resolve this is to contact the only witness, who has nothing to gain, the nurse.
