Affidavit as evidence for ROC

[osisgerd29 0]

Just wanted to know if affidavits submitted with ROC needs to be notarized? 

 

my name is not on the rental agreement for the apartment so i'm thinking of letting the apartment manager sign an affidavit stating that I lived there with my wife. Can we do this? 

Thank you.

 

as far as evidence for ROC we have:

-joint tax returns

- joint bank account and credit cards

- Bank statements showing separate deposits of our individual salary on the same account

- Used  checks with our name on it to pay for house rent

- health insurance cards

-Health bill info with we as beneficiary and our son

- Dental plans 

-DL and letter showing same address

- retirement plan showing me as a beneficiary and our son

-birth certificate of our son

- Colonial Disability  Plan with me as a beneficiary

- Several pictures

 

Question: 

- Phone Bills ( she also added me recently  but before that I was under her mom's plan,whay to do with this?)

Do we need will or Dpoa? 

 

Answers are much appreciated . Thank you ?
