Your use of the word 'attorney' (and particularly the abbreviation 'atty') suggests that you're in the USA. This is a UK-based site. Our legal practices differ greatly from those of the USA. You might get a more useful answer by posting on a US site, such as one of these:

Here in the UK it would be extremely unusual (and certainly unprofessional) for a solicitor (= US 'attorney') to disclose the contents of a will (unless, of course the testator requested that he do so) prior to the death of the testator.
However that assumes that the will in question is that of your aunt. It's possible that your uncle might have owned property in his own name, which he left to you and your brother subject to the restriction that his wife could continue to live there until her death. In which case the attorney would have become free to disclose the contents of your
uncle's will upon
his death (with no need to wait until his wife died).
