Tenant adopting child

[Michael Greer]

Hello,

I have a property with a tenant that I inherited when I purchased the property..

She is an older woman with adult children that, at one point, moved in with her without notifying me.

We've got that all cleaned up, but now she is adopting a 2yo child.

It's a noble act, but how does this effect me as the owner?

She handed me papers to sign from the county acknowledging that I am the owner. I took a pic and told her I would review it.

Do I have to accept this?

How do I document a toddler in my property as a tenant now?

Should I be raising rent with the addition of another person on the lease?

Apologies for ignorance, this one is new to me.

Thanks in advance

Mike
