What is the legal age required for a person to be an executor of a will?

I believe they must be 18 years of age or older.  Please feel free to give me a call if you would like to discuss other options.  You may name another contingent executor in the event that your primary named executor cannot serve.

I am not admitted in Massachusetts. 

The statutes do not state a specific age but rather state that "the named person" is "if of full age and legal capacity."   I would assume this to mean that they have to be at least 18 years of age - not a minor - as the minimum age requirement in the state.  I would check with an attorney in your area or the courts to be sure.
