Man Claimed To Be My Mother’s Biological Father, Looking To Stop The Selling Of His Home Until Dna Results Are Clear.

Mothers location: Kentucky

Potential paternity location: Ohio

My mother has never had a relationship with her father and the man listed on her birth certificate is deceased, she only met him twice in her lifetime and he passed in 2024. Fast forward to 2026 and around 3 weeks ago a woman from Ohio, not a complete stranger because she knows some family we have in Ohio, told her that her father was on hospice. Obviously my mom was confused and told her that her dad passed in 2024. This woman is the sister of the now proposed father so if true my mothers aunt. Aunt is saying that this man was aware he was her father and tried to reach out several times but was prevented by his wife as we believe he may have been married or at least engaged at the time of my moms conception. He passed away about 3 days after this contact and was not able to speak for an extended amount of time before that from disease progression. My mom’s mother passed in 2009 so no way to get any information from her. My mom’s biological uncle is now confirming this story. The aunt through the proposed dad is willing and insistent on getting a DNA test because she is saying her brothers wishes were for my mom to be included in the benefiting of the selling of his estate. His wife is also deceased. None of his other children are aware that we know of. We know this is a time sensitive issue is she chooses to pursue it but we are lost on where to start.

Main questions:

What kind of attorney are we looking for here?

Does the attorney need to be located in the state we are in or the state that the father lived in?

We looked into private DNA testing between my mom and aunt before involving an attorney for validity of the claim but it looks like the wait times are very long and it wouldn’t an admissible in court anyway. Does an attorney need to reach out to pause any will movement while we wait for the DNA test to come back?

Lastly, we do not know the phrasing of this will. I have no idea if it simply states children or if it specifically says the names of the children perceived in marriage or any variation of the such. Would phrasing prevent my mom from any benefit from this situation even if it did turn out it he was her father?

Thank you in advance. I know it sounds like she is trying to hook on to a cash grab but my mom grew up homeless and starving and my grandmother quite literally worked herself to death living in an income based apartment. If he was aware he was her father and allowed her to suffer so much as a child, I think it is okay for her to reap some benefit from his success that she never saw.
