Filing for Special Monthly Compensation Increase-is it same as a regular C and P process?

My lay letters were not notarized.  They also did not contain any statements that they were true and honest.  They did include contact info though.

I would recommend you get a letter from your employer.  An employer letter helped me greatly in getting UI.  I can say that the RO's do not seem to put much thought into lay letters but I have found that the BVA read these letters and chastised the RO for not properly applying what the letters said.
