My partner of 13 years recently passed & told me several times over the course of the years that I was the beneficiary of his retirement account of which I was told was of a substantial amount.
I assume you're talking about a boyfriend, but please explain if that's not what you mean. Also, how long ago did he die? What sort of retirement account are we talking about? Did he have a will or trust? Has his estate been probated (or is probate ongoing)?
he sent all financial papers, including for the retirement account to his father I'm assuming for safekeeping has me concerned.
That's an awfully strange thing for an adult to do. Why would his financial papers be safer with his father than in his/your home?
I know that my partner switched companies awhile back but I'm unsure of which one.
Meaning you don't know where your boyfriend worked?
How would I find out if I was named the beneficiary?
So...basically what you've told us is that your boyfriend of well over a decade recently (?) died. He maintained no financial papers in what I assume was your shared residence, and you don't know where he worked. He told you that you were the beneficiary of some sort of retirement account, but you appear to know nothing at all about the type of account, and presumably you don't know whether it was an account connected with his employer. Have I got all that correct?
If so, then your post suggests two things to me. The first is that he was bull[bleep]ing you. The second is that his father may have some information. If you knew who his employer was, you could call the benefits person there.
Call the company that I believed he moved the account to?
By calling someone you might get some information. If you don't call, you won't get any info.
What I am concerned about is. . . .
Speculation.
What legal recourse would I have if that has occurred, especially within the timeframe that he was in hospital & unable to communicate?
I see no point in heaping speculation on top of a hypothetical set of facts other than to say you might be able to sue.
his assets, which also includes property & home which he also wanted me to have so I would always be sure I
had a home.
If he
really wanted you to have these things, then there are several things he would have done, and hiding his financial life from you by sending all papers to his father and not even letting you know where he worked are not among those things.
Unless you can gather a lot more information, about the only possibility is that you could seek to probate his estate and seek to be appointed administrator/executor. If you are successful in that regard, then you would have the ability to compel his father to turn over his financial documentation to you. Beyond that, as a mere boy/girlfriend, you have no more entitlement to anything than I do.
