Deceased Girlfriend’s Mother Threatening To Sue For Equity In My Home

Location: Florida

Throwaway since I don’t know who might see this.

My girlfriend and I were together for 7 years. She passed away 2 years ago. She lived with me for 5 of the seven years we were together. I bought my home a year into our relationship. I was the only one on the mortgage and now I own the home. I came into full ownership of the home after she passed. My name is also the only one on all bills. My girlfriend did not pay rent.

My girlfriend’s mother has contacted me and has informed me that she intends to sue me for equity in the home, claiming that she has proof that my girlfriend invested in the home and that she paid to have renovations done to the house (we renovated one of the bathrooms and a bedroom and I paid all costs related to that). She did so via her family attorney who I looked up and I don’t believe works in this type of law, he appears to do wills and estate planning. She is saying I owe my girlfriend’s estate $100,000. I have no idea where she could have even come up with this number.

For what it is worth, my girlfriend’s mother has never liked me and has been particularly vicious towards me, including an accusation that I was responsible for my girlfriend’s death (she died of natural causes). I have not spoken to her since this outburst which was shortly after my girlfriend’s funeral. Her mother was the executor of my girlfriend’s estate. My girlfriend’s family, including her father and siblings, have always supported me and have denounced her.

Basically I am wondering if I need to actually need to worry about this and what questions I need to ask when I meet with an attorney on Monday. My name is on everything, I can’t even find any receipts or anything that even has her name on it. This coming from an actual attorney does have me spooked a bit. I received this notice yesterday.

Thanks for your time.

EDIT: By saying “come into ownership of the home” I mean to say I paid off the mortgage. Sorry for any confusion

EDIT 2: Thank you to everyone who has answered my questions.

To clarify some things: No, her name has never been on the deed to the house and also no, we did not share bank accounts. I paid for everything out of my own accounts: the mortgage, the renovations, everything. She at no point contributed to these.
