1) If your employer has insurance or other benefits you can list your spouse's name there or on ur life insurance policy etc to show them the relationship is genuine. (I skipped that option as I didn't have any of those)Proof of relationship section
1) Important documents for you and your spouse showing that you are recognized as each other's spouse (such as employment or insurance benefits)
This is very confusing what do they mean by employment documents?
2) Other proof that your relationship is recognized by your friends and/or family
for this, what form of evidence is required?
2) I did that one i got letters written from family and friend's from both sides.
