You could get a video proof, but as that can be proven wrong to be a fake in itself. You could also get records of your last checks or whatever it was that whomever is was who forged the item, and compare it in a court of law with the forged ones. Also, the not very probable to happen, but entirely possible, is to get that person to admit to it.
To prove that the signature is a forgery, you would use expert handwriting analysis. To prove that a specific person forged your signature is a bit harder, but if you can pin down the time when the document in question was signed, there MIGHT be relevant security camera footage. Otherwise the evidence is circumstantial. If a particular person is trying to make use of this forged document (e.g., is trying to cash a forged check) then there is a reasonable presumption that he is the person who committed the forgery.

Despite what the crime shows portray on television, it is NOT required that a handwriting expert be retained in order to prove guilt (or innocence). Expert testimony isn't necessarily needed if the forgery can be proven by other means.

You can't prove a negative with direct evidence.
The best way to prove employee dishonesty is by keeping a record of evidence that may prove your view. Without evidence or a witness, it may be difficult to prove it.
Enough evidence is needed to convince a jury beyond a reasonable doubt that the person committed the homicide.
