Legal Question in Wills and Trusts in Nevada

If Grandpa did, indeed, have a will, the neighbor (assuming she was named as the Personal Representative or Executrix) is required to file it in the county where he resided. Contact the County Clerk and request a copy of the will (now a public document), then find if a probate has been opened in that county's probate court. If neither has been done, and you are confident that Grandpa named you as a beneficiary in his will, you are entitled to obtain a copy of it from whoever has it in his/her possession. YOU can file the will and even open a probate, if that is what is necessary to properly disburse the property of his estate.

Sometimes the most obstinate relative or family friend will quickly comply with the law when presented a "nastygram" from a law office, instead of just calls from other family members. Do not delay, as property will quickly start to "evaporate" and people who are in the know will disappear with whatever Grandpa left behind.
