Can my spouse take prior year AMT credit if filing status is changed from MFJ to MFS?

Hi, tax experts,

 

My previous year filing status is MFJ and we have some AMT credits carried over due to previous ISO exercise. In this year we can use the credits but we are considering MFS which can reduce state tax in our condition. In this case, can my spouse use the AMT credit that we carried over last year?

If yes, how do we report 8801 and split the credit carry overs if both of us can use the credit in this year?
