With any type of monetary transfer that goes to another country and depending on amount, first thing MG will ask you is if you know the person and how. You can just tell him he's a relative and they'll accept that. They just need a justification, and won't investigate if it's true or not. Second they'll ask what the money transfer is for, just say gift. Less questions that way.
It may seem intimidating at first because MG will call you out of nowhere to provide this information. They are strict and I always found it odd that they are looking out for you in a "Big Brother Govt" kind of way.
