My child's mother is deceased how do I claim her?

You don’t claim her but if you were married during 2022 you can file married jointly.

Sorry for your loss. Who are you referring to has "her"? The child? Or the mother?

If you were legally married to the mother on Dec 31 of the tax year, you can still file a joint return so you get the full standard deduction for both of you. When entering the mother's information on your return, you'll select the option to indicate she passed away during the year.

If you were not legally married, you generally can't file a joint return with the mother. But there are exceptions where you can be "considered married". I won't get into that unless necessary.

If you were not legally married and you supported your dependent child for at least half the tax year, (qualifying child dependent I assume) then you can file as Head of Household, which gives you a bigger standard deduction.

The above is "rough", as you've provided no details about the situation to work with, and I'm making a lot of assumptions would could very well be wrong.

Who do you want to claim?  The mother or your child?  When did she pass?  If you weren't married you file as Single or Head of Household if you can claim a child.
