signature experts

I am looking for an expert in signature analysis to assist me with a legal dispute. Specifically, I need forensic signature analysis to be performed on a total of 1-3 signatures. The purpose of this analysis is to provide support in the legal dispute. An expert in this field is needed to properly and accurately analyze the signatures. If you have experience in performing forensic signature analysis, I would be very interested in hearing more about your services. Thank you for your time.

The first PEDRO LAU is the only signature to verify if all four came from same person
