Determining who authored or signed a particular document can be a challenge. While computer software has made it easier to tell when a word-processing file was created or modified by a particular machine, determining whether a handwritten item belongs to a particular writer remains difficult. Enter handwriting expert witnesses, who specialize in helping attorneys settle questions about written evidence.
A handwriting expert witness can help determine who wrote a particular word or signature. They can also help settle questions about when a particular item was written down, using methods such as ink dating and analysis. As expert witnesses, handwriting experts can analyze information, form opinions, and prepare reports in a similar fashion to other types of expert witnesses. Courts have accepted testimony from handwriting experts under both the Daubert and Frye standards. The expert compares the characteristics that appear in both samples and forms an opinion as to whether the document in question matches the known sample.
Handwriting expert witnesses typically do not state with certainty that a particular handwriting sample came from a particular individual, even if the goal of litigation is to prove that one person wrote a particular document. Instead, handwriting experts will express their opinion as to whether the characteristics of the handwriting on the document in question are consistent or inconsistent with the known sample used for comparison. Nonetheless, the testimony of a handwriting expert can help bolster a claim that the questioned document was or was not written by a particular person, depending on which opinion the expert develops.

This article addresses the use of forensic document examin-ers FDEs in Florida will contests. The first decision is whether to retain an FDE. This decision turns on several issues, including the nature and strength of the claims, the quality of lay witness testimony, and whether the opponent will use expert testimony. Once the decision to retain an FDE is made, the practitioner must decide on the type of FDE to retain and whether the FDE will testify at trial or merely assist with trial preparation and consult during the course of the trial.
These considerations are integral to the successful use of an FDE in will contests. A will contest involving allegations of will-tampering or spoliation may lend itself to the use of an FDE. In performing this inspection and testing, the FDE should examine, inter alia, the handwriting, typing, type font, paper, inks, staple holes, indentations, and format of the will.
In the hands of an FDE, the pedestrian qualities of an ordinary document are clues to its integrity, sanctity, history, and creation. The decision to retain an FDE should be made at the outset of the case. Although an FDE can educate and help the practitioner understand contested evidence, the most pragmatic reason for timely retention of an FDE is that there may be few qualified and effective FDEs in a given locale, and retention of a leading FDE should keep the adversary from retaining that same expert.
The practitioner should enter into a confidentiality agreement with the retained FDE that cloaks all information with the protection of the attorney work product doctrine. Take, for instance, the facts of a fairly typical will contest: dissatisfied with the bequest provided for in the probated will, the challenger seeks to set aside that will in favor of another will on the ground that the former has been spoliated e. The challenger may rely on expert opinion to support allegations of spoliation and documentary legerdemain.

Ink Dating is done in two primary forms. The first ink dating method is the static approach, which determines when the ink being examined was manufactured. The second ink dating method is the dynamic approach, this method is to determine when the writing occurred, or in simple terms, how long the ink has been on the paper. The ink dating static approach is typically more useful as the difference between the date on the document and the present time increases.
Several different tests exist in this form of ink dating. These ink dating methods include the comparison of the examined ink to a known library of standards, commonly called the library approach, the detection of chemical date tags placed in the ink purposefully by the manufacturer, commonly called the date tag method, and also the determination of the type of ink writing instrument used. The determination of the type of writing instrument is probably the oldest method of ink dating.
This ink dating method primarily involves microscopic examinations and can also incorporate some basic chemical solubility testing. Some examinations can be performed on fountain pens to determine type of nib, type of ink and the first date of introduction of each of these. However, since this is a very small portion of the actual type of cases seen, we will concentrate primarily on more recent developments. Other pages discuss the use of infrared to discriminate the differences between inks that visually and microscopically look identical.
