Generally, written testimony is unavailing if the other side does not have a chance to cross-examine the witness. It doesn't hurt to try, though, if that's the best you can do. A notarized statement might be very helpful to establish damages if the other side defaults (does not show up) and you can be awarded whatever damages you can prove.
