I have a new client that is suppose to get a 8332 form from her ex-husband. The husband says he is not signing anything but allowing her (non-custodial parent) claim one of the children this year. in her past returns it has HOH on there but as I was reading that in order to claim the HOH in a divorce situation is if they life 51% of the time with custodial parent and 51% of the time with the non-custodial parent. The non-custodial parent only gets visitation every other week and she pays child support for her kids. 

Should i add the form 8332 on the tax return?

can she claim HOH or should i change it to single? Can i do the HOH and fill in the child's name below as non dependent?

on the dependent information : what would be the correct way to fill out the EIC, lived with taxpayer, (L) dependent lived with client or (Q) non dependent?
