@jpohnsonpm if it was jointly held, then 50/50.
Note that filing separately is not a good idea from a financial standpoint - the taxes owed when the two returns are added together are normally much larger than when filing joint. 96% of married couples file joint.
if the decision to file 'separate" reflects the status of the marriage, I understand and sorry for that, but if it being done solely on the basis of financial matters, it is highly unlikely to be a good decision.
