If i was living with someone in a domestic partnership just the 2 of us living at our address, can 1 of us claim head of household even though we filed separately?

To file as Head of Household, you must have a qualifying child or dependent.

 

There are conditions to satisfy in order to file as Head of household. You must:

 

• Pay for more than half of the household expenses
• Be considered unmarried on the last day of the tax year, and
• You must have a qualifying child or dependent.

Please read this TurboTax article for more information.

 

If you don't have a qualifying child or dependent, you must both file Single.

 

For Head of Household filing status you must have a qualifying person as a dependent and you must have provided over one-half of the cost to maintain the home.

 

See this TurboTax support FAQ for Head of Household - https://ttlc.intuit.com/turbotax-support/en-us/help-article/tax-filing-status/qualify-head-household-2021/L0NxUtVc2_US_en_US?uid=lu8x7m6p

Does one of you have a qualified dependent?   You cannot file as HOH unless you have a qualified dependent.

If it was "just the two of you" ---no, neither one of you can file as HOH.
