"The Source," published by Ancestry.com has a table of ages for legal actions. The data was extracted from several legal references. It lists the common-law age for witnessing documents as the age of discretion, 14 for males, 12 for females. There is no note of an overriding VA statute. I did not find one in the colonial statutes covered in Henings. The lawyers can provide further insight. This chapter was written by Arlene H. Eakle.
