What happens if I transfer my car title 16 months prior to my bankruptcy filing? How?

The reason you have to list this transfer is because the bankruptcy code says so. Whether you or your friend have to pay this money to the trustee will depend on whether this sale was made under terms that would be considered fair. For example, that the car was worth only the $4,500 you received for it, and not $15,000. A big part of bankruptcy is being willing to comply with the law, because even for something of low importance, violating the bankruptcy law can turn you into a criminal.

If $4,500 was the reasonable value of the car? If it was then there is no problem. If the car was worth more, then your friend may have to give the difference to the trustee.

The law allows the bankruptcy trustee to scrutinize any transfers, especially to relatives or friends, to determine if you obtained appropriate value for them or if it was part of a scheme to hide assets. So if you obtained reasonable value for the car you sold to your friend, it should not be a problem. If it was significantly less than market value, however, the trustee has the legal power to demand that your friend pay more to get it up to the equivalent of an arms-length transaction. If the trustee wants to recover the lost value in the transfer, s/he will first give you an opportunity to pay it rather than going after your friend. The whole purpose of this rule is to prevent sham transactions that would improperly shelter assets from your creditors. If your deal was fair then there is nothing to fear in reporting it.
