Adding New Co owner

Well, For Your aware of sec 56(2)(x)...
And also good about Your thought/action for adding...

But,

The question is not clear. Give some more clarity about the said query.
Also better to consider this with nearest professional...

( I want to know Capital Gain tax implications on my hand.

If applicable then what will be sale consideration and cost.)

You can easily add.

Yes....My question is what is the implications of Capital Gain. Right now I'm 100% owner of house. If I add wife as co owner then I'll have 50% share. 

Will it amount to transfer even though no consideration received?

Make just Gift deed and register same and pay stamp duty and registration charges as co owner

In case of Gift Deed recipient is not liable under IFOS but will it amount to transfer in My hands? as I'm transferring 50% share to spouse. won't it attract capital gain?
