Grandmother Passed, Lawyer Says They Can't Send Me Her Will

The deceased passed on in Richmond County, NY.

First off, if a validly signed and executed will says I get $0, I won't contest it. If those were her final wishes, I have no issue with respecting those. I'm posting here because I suspect that it's more complex than that.

I had a pretty low amount of communication with my grandmother for the last few years of her life. Essentially, my father committed a certain crime which I witnessed, she took his side, and I didn't. He is now deceased and she has no other blood relatives. She told me that she had a will, but the details of it, including whether it was validly filed, are a complete unknown to me.

On Friday, I got a call from a lawyer informing me that my grandmother passed on and asking me for my address to send the will to. He called me back pretty quickly saying that my address doesn't show up in his system and he can't send me the will without my "real" address. I confirmed the address, he got frustrated because it wouldn't be accepted by his system and said he'd follow up after the holidays.

I've lived at this address for years now. It's on my drivers license and I've received summons for jury duty here. All of that is to say that my home address unambiguously exists. While I doubt "we couldn't send a relative the will because the program I use didn't accept it as a real address" would be accepted by a probate court or whatever, it sounds strange to me.

I have the contact info of an estate attorney I've worked with before, but if there are any lower investment options I could use, I would prefer to start with those.

Thank you for reading this and for any advice which you may have.
