We are applying for common law, where do you see that the letters need to be notarized?
Appendix A for Germany reads:
PROOF OF RELATIONSHIP TO SPONSOR
If you are being sponsored by your parent, you must provide proof of the relationship such as birth
certificates, baptismal certificates or other official document naming your parents.
If you are being sponsored by your spouse, common-law partner or conjugal partner, you must send
evidence of the relationship between you and your sponsor such as wedding photos or proof that
you are partners, letters between you and your sponsor, and telephone bills showing contact
between you and your sponsor.
Note: Photos must be loose. Do not send them in binders, albums, frames or other such containers.
Do not send video discs or video cassettes. Do not send musical greeting cards or other similar
documents containing electronic or mechanical devices.
Proof of your sponsor’s visits such as airline ticket coupons, boarding passes, copies of pages of
your sponsor's passport showing entry/exit stamps.
If you are a common-law or conjugal partner, provide evidence that your relationship is genuine and
continuing and has existed for at least 12 months prior to your application. Also provide details of the
history of your relationship and at least two statutory declarations from individuals with personal
knowledge of your relationship supporting your claim that the relationship is genuine and continuing.
Note :The sponsor and the applicant who are common law or conjugal partners must provide
historical evidence of their ongoing relationship. If they are in a relationship of two years or less and
have no children together, the applicant will receive conditional permanent resident status, if the
application is approved.
And in IMM 5491, it specifically says to send in photocopies for them (Item 25, Supporting documents, Proof of relationship)
