Experience letter from Ex-Manager email in plain paper or Affidavit

[goodluck]

Hi,

 

My first company is closed and its been more than 10 years. I need to provide experience letter for that period, attorney has suggested to get letter from previous supervisor but I have a question if letter in email form works or should I get affidavit from ex-manager.

 

Any help or suggestion would be appreciated.

 

Thanks!

No Affidavits needed. But he should agree to be contacted by your new company.
