Huf dissolution

I am having a HUF in my name . Being the Karta of the HUF aged 83 years along with my two married sons, i am having one immovable property and bank balance in the name of the HUF. Now, i want to dissolve the same and transferring equal rights to all three including myself as karta (in my personal account). My queries are: 1. Can i transfer the cash lying in the bank to one my son and myself by showing them as gift transfer by executing gift deeds? Is there any limit of the amount should be transferred? 2. The property would be transferred to my another son. Do i have execute any separate deed for the same and stamp duty need to be paid on the market value of the property as on date (as per the WB state Act, it is about to .6% and additional of 1 % if the value exceeds Rs. 40 lacs. Am i correct? 3. In the event of the immovable transfer, do i have to make any separate deed or only one partition deed will suffice? Need to know the manner of registration of the same. 4. After executing of the Deed, then have to move for AO Order or before any prior approval required? Kindly provide your valuable views or suggestions. Thank you
