Selling a vehicle or property if one does not have the logbook or title deeds in one's possession

Q: 

1. A dealer purchases cars from auctions. Payment is made for these vehicles and the dealer has possession of the vehicle. However, the auctioneers generally delay paperwork and release the logbook, etc. months later. Can the dealer sell the cars before receiving paperwork? 

2. A person purchases a property but does not have the title deed as yet. It is still being processed with the master's office. Is he considered as the owner? Can he sell the property? Can he rent out the property and receive rentals?

Forging a document to earn a job

Q: To qualify for CA (Chartered Accountant) in Bangladesh, one has to pass 17 papers and also complete 2 or 3 or 4 years of article ship (practical training). Now my friend has passed the CA exam by passing all the 17 papers by giving the exam in the most ethical manner as possible but he did a dummy article ship (forged article ship documents). 

Now he got a halal job because he is a qualified CA. Without doing the article ship, one cannot give the last level of CA exam (last three exams). Is his income halal as he forged the article ship document?
