I'll give you the names of the two property lawyers I've used, and they are both responsive to WhatsApp. However, your case is not something I've tried, but I've heard of many people transfering the ownership of their property to a family member. One thing you should note is that this normally means the new owner/buyer still needs to pay the stamp duty that applies to them (if they are a HKPR and this will be their only HK property they'll pay the lowest rate). I think you can usually 'sell'/transfer the property at around 80% of its market value, but I think the lowest price you can sell/transfer your property for is up to the relevant government department.

As for property lawyers that I've used:
Mr. See 9198 4456 His office is on the 12/F of the Hang Seng Mong Kok Building. He charged me 5,500 to help me sell my old flat, and 6,500 to help me buy my current flat, and I completed both sales in January 2020.
David Ng 9852 2246 His office is in Central (141 Des Voeux Rd). He offered to help me sell my old flat for 6,000, and he offered to help me buy my current flat for 6,500. I used him to help me complete the sale of my first flat in early 2016.
They both were fine for me, but feel free to use any lawyer recommended by anyone you trust. To me I think they are mainly a dime a dozen like property agents, but they are cheap enough to not fret about having to use them. If you personally know anyone that has bought a property in HK, ask them for a lawyer recommendation.
