Florida’s Handwriting Expert

Forgery is the process of making, adapting, or imitating objects, statistics, or documents with the intent to deceive impose a legal liability with the intent to prejudice, damage, or defraud. Document examiners/Handwriting Experts do not offer an opinion of forgery because forgery includes the intent to defraud. Only the trier-of-fact can make a determination regarding intent. The document examiner/handwriting expert will determine the authenticity of the document and will testify in court to support their opinion.

I recently had the pleasure of working with Dianne Peterson and I am incredibly impressed with the level of professionalism, expertise, and thoroughness they demonstrated throughout the process. Dianne was hired to analyze handwriting for a critical case, and their work exceeded all expectations. From the initial consultation, it was clear that she had a deep understanding of forensic handwriting analysis. They took the time to carefully examine the documents in question, providing detailed reports and clear explanations of their findings. What stood out the most was their ability to break down complex technical details into easily understandable terms, which was incredibly helpful for everyone involved in the case. Most importantly her analysis was not only thorough but also compelling. Their testimony in court was strong and clear as a result, the findings were approved and accepted by the court. This success was a testament to their expertise and dedication. I highly recommend Dianne to anyone in need of a skilled and reliable handwriting expert. Their professionalism, attention to detail, and ability to deliver results make them an outstanding choice. Thanks to their work, we were able to achieve a favorable outcome in our case!
