My Parents Old Landlord Is Treating To Charge My Brother And I With Paying My Parents “debt” To Her.

In march of 2024 my grandfather ( the owner of our old home) past away. Before he past away his ex wife stepped into the picture and took over as his power of attorney in doing so she had him sign over his property’s to her. After this happened she started claiming my parents owed her $25,000 in back rent for this property and if they didn’t pay it we had to move out. I would like to state that my grandfather never spoke of this the entire last few years of us living there until she took over as POA and he was extremely ill on his death bed.This never went to court.We moved out and into our new home in August of 2024. It is now January of 2025 and she just messaged my brother and I saying she will accept a total payment of $8,000 from all of us to settle the $25,000 debt . She is saying that if it is not paid by my parents or my brother and I she will take all of us to court and all of us will be held accountable. For context my brother and I grew up in this home from ages 3-21 & 6-23 it was our childhood home we grew up in. Our names are no where on any kind of written lease nor did we ever have any kind of verbal agreement with my grandfather or her as a tenant or as someone who is accountable for rent. So would this really be a debt that could be held against my brother and I?
