Good faith marriage affidavit sample letter

A good faith affidavit letter is simply a letter to show that, in your opinion, and to the best of your knowledge, the applicant’s marriage has been entered into in ‘good faith’ and is genuine, not a bogus relationship for some other reason or gain.

Being asked to provide an affidavit letter testifying how well you understand a couple’s marriage can be daunting, however as long as you are honest and add as much information as possible showing from your point of view, that this is indeed a committed relationship, then it is quite straightforward.

A marriage affidavit letter should contain the following:

  1. Your full name
  2. Date and place of your birth
  3. Your current address in full
  4. Your relationship with the applicant and their spouse
  5. How your relationship began, including
    • How long you’ve known them
    • Where or how you met them
    • How often you see them
  6. Date
  7. Your signature

Remember your letter is to help the couple prove that they have a genuine relationship so you should give personal experiences to show why you believe this is true.

The following template letter should be adjusted to include those personal experiences.

It is best if it is typewritten not written by hand but should be signed by you.
