Answer:
no fiduciary relationship has been established
Explanation:
Based on the information provided within the question it can be said that in this scenario no fiduciary relationship has been established. A fiduciary is a person who holds a legal or ethical relationship that revolves around trust with another person or group. This type of person usually handles money for other people. In this scenario though, since the individual is just taking over temporarily for the couple and is not handling the couples house purchase, then no relationship has been established.
