It may be – only an attorney can give a legal opinion on the legality of the document. Every state has its own laws governing what constitutes a valid Will. Even if the out-of-state Will is valid, a North Carolina attorney could include special provisions under North Carolina law in your Will which could save time and money in settling your estate. For instance, your Will should include a North Carolina self-proving affidavit to eliminate the requirement for testimony at the time of your death from the witnesses on your Will.
Another factor to consider is that the cost for an attorney to review an out of state Will may be more than the cost of preparing a new Will that clearly complies with North Carolina law.
