Hello! My name is XXXXX XXXXX I look forward to helping you today. Please note: (1) this is general information only, not legal advice, and, (2) there may be a slight delay between your follow ups and my replies.
My condolences on the loss of your sister and I am sorry you are dealing with this situation. First, a Living Will/Advance Directive
does not have an estate distribution afftect on an estate and should not impact the estate and it should distribute according to intestate succession laws.
However, there are no guarantees but the boyfriend would have an uphill battle proving that such an addendum on the back of an Advance Directive was intended to be a last will
and testament, that the witnesses could attest to your sister's signature and witnessed her sigining at the end of the document and as such would be a valid will.
If I am in your shoes I am not going to let the off chance that this character would actually prevail on a weak claim to real property of an estate to which your father should take by intestate succession.
All my best & encouragement.
