I cannot answer to Alabama as every State has its own probate law. However, in Washington State a Will is private. The only way he can see the will is if his mother let's him. If his mother has passed away then the probate court should have a copy of the will. He should contact the court directly or hire a legal messenger service to get the court record and mail it to him. He could also contact an attorney near the court in question.
At your service,
