Absolutely. An up to date information is always preferred because it could affect your rating or payment. Changes could include marital status, birth of a baby, child adoption or any other life changes.
I heard form some people that disability compensations could be increased. How's that?
That information is correct. IF you have a disability rating which goes over 30%, you can get a higher payment adding eligible dependents.
But that's the only way to get an increase? What about a worsening on my possible disability?
