Income from house property

Me and my husband booked a apartment in joint name for a total value of say 'X'.

I paid the amount "Y" directly to builder from my bank account.

My husband paid the balance amount from his bank account and from the home loan taken from bank for which he is paying the EMI.

My question is "In what proportion will the income (rental) from this property will be shared between me and my husband for purpose of income tax." 

Note: There is no clear mention of the % share of the property in apartment  booking agreement  with builder
