I also think you need to consult an attorney or tax professional. I believe that if you were the sole legal owner of the property, then you alone are responsible for any capital gain tax due on the sale, regardless of what you do with the proceeds.
In fact, since you are receiving nothing in return for the funds you are transferring to your relatives, I believe an IRS auditor will construe the "transfers" to be gifts.
