No. She has rights under State law as the surviving spouse. In Nevada if the assets were all acquired during marriage she is entitled to 50% even if he left a Will leaving her nothing.

Until a couple is granted a divorce by a court, they are considered married. So your stepmother was still your father's wife at the time of his death. Many states allow a surviving spouse some part of the estate (what used to be called the widow's portion) but it's certainly not 50%. If the will is valid, it's unlikely that your stepmother can claim anything beyond what state statute allows.

For a will to have effect on real property ownership in Texas, the will must be presented to a Texas probate court and probated in some fashion. No one is required to probate a will. If you have an original will to probate, you can offer it within 4 years of the death of your grandfather. After 4 years it might be admitted as a muniment of title, but formal administration is not an option. If your mother was your grandfather's only heir (heirs are determined by law , beneficiaries are designated in a will) and no will was presented for probate, full title of the property would pass to your mother. Your mother's interest in the property could have transfered in full to your father at her death. If you and your siblings want to sell the property, I'd make sure you have some ownership in it first.
