A Massachusetts Affidavit of Executor is a document that is required to be filled out when someone is appointed to act as an executor of an estate in the state of Massachusetts. The affidavit is filed with the probate court to provide evidence that the individual has been appointed as the executor and to outline the executor's responsibilities. There are two types of Massachusetts Affidavits of Executor. The first is the General Affidavit of Executor, which is used when a deceased individual has not created a will. This affidavit is used to appoint the executor of the estate and to provide proof that the executor has accepted the responsibility. The second type of affidavit is the Limited Affidavit of Executor, which is used when a deceased individual has created a will. This affidavit is used to appoint the executor of the estate and to provide evidence that the executor is aware of his/her obligations and duties as outlined in the will.
