   Can you enter expenses/investments that are in someone else’s name and that were paid from someone else’s account (e.g. parents)?

For example: parents bought a passenger car using their account and may or may not have put it in your name.

For example: your parents paid for your mobile phone via their account. Can you still claim this expense?
