Hello Nighttrocker
I have a slightly different opinion
Check out my last post on Proof of Funds and you gain some experience from some guys
4months from my understanding is to show account performance
So a totally blank account before your deposite might question source of funds
Or else you can prove source, like sales deed of property or stock ... with concrete evidence
Otherwise, if your uncle is direct uncle (preferable paternal with the same surname), his statement can stand for you
But you must ensure
1.The account performance for the last six months is solid
2.That he has far in excess of what you need ( because they may not assume that he would empty all his account for a nephew or nice)
3.That he is willing to give you proofs for his source of funds (eg business registration documents, tax receipts etc - see student permit checklist for others)
4.That you get a letter from him showing his willingness to sponsor you
5. If you can get any proof of relationship with the uncle, it would also buttress your point (eg birth certificate of your father (or mother as the case may be) and him, to show the same parental name)
I feel you can also attach your account statement to the above and have him state in the letter that in support of the admission, he has provided the funds you have in the account.
I hope this helps and guides you in whatever decision you need to make
