Hi Teana. Your sister's estate and her assets are not her husband's personal piggy bank. If hhe doesn't produce the will and cause it to be filed for probate, usually within 30 days of the date of your sister's death, you can file your own petition with the court asking the court to order it produced and file. Once filed it becomes public record and you can contact the clerk of the county probate court for directions on how to access a copy of the will.
And, if the will was changed close to her death and it changed the terms of the will to exclude you and your siblings, then you can contest the new will by showing one or more of the following: lack of requisite mental capacity, coercion, duress, mistake, fraud, and/or undue influence. Although you have the burden of proof, given such facts, most courts would rules in your favor and throw out this new will.
