Transfer of Property via Gift Deed or Will

My mother wants to name her property a house and shop in my name because my brother can create problems after she dies. I am confused. I dont want the shop in my name right now because I will have to pay tax on rent income which I am not even getting. She will be getting the rent till she is alive. Can you please suggest me a best option right now which makes me inherit her house and shop after she passes away and no contest can happen. I was considering Gift Deed, Will or Co-ownership. Gift Deed again will transfer the property in my name which I dont want right now. Will can be tested and I am not sure about co-ownership. Please advice.
