OBTAINING KNOWN HANDWRITING
SPECIMENS
Thomas W. Vastrick
Forensic Document Examiner
One of the most commonly asked questions of forensic document examiners is,
“What kind of handwriting specimens do you need for comparison purposes?” The following are some general guidelines to follow when preparing a handwriting case for submission to a forensic document examiner.
NON-REQUEST SPECIMENS
Non-request specimens are handwriting samples that are taken from the subjects day-to-day activities. These may include such items as canceled checks, employment applications, signatures on driver’s licenses and the like. When selecting non-request specimens consider the following:
Contemporaneous
One’s handwriting can change or evolve over long and even short periods of time. Handwriting and signature specimens should be dated as close as possible to the date of the purported writings - ideally, from a few months before to a few months after to offset this phenomenon. This is particularly important if the purported writer is elderly, ill or sustained an injury around the date of the writings.
Comparable
If a forensic document examiner is to compare cursive writings, they cannot perform a thorough examination from printed specimens. Submissions should include letters and letter combinations that are repeated in the questioned writings.In addition, the specimens should be of similar format - meaning that the specimens should be upper or lower case and cursive or printed as is reflected in the questioned writing.
How Much?
A forensic document examination cannot be adequately performed when comparing one signature to one other signature. Handwriting identification is based on habits. Habits can only be determined through the scrutinization of numerous specimens. The client should make a dedicated effort to obtain as many specimens as they can possible find.
REQUEST SPECIMENS
Request specimens are those that are actually taken from the subject for the expressed purpose of forensic document examination. Below are some general guidelines to follow when taking handwriting specimens.
Preparation
Taking proper handwriting specimens involves more than slapping a few signature samples onto a sheet of paper in five minutes. It takes preparation and a flexible action plan to deal with all kinds of developments along the way.
If at all possible, obtain non-request specimens prior to taking the request specimens. This will provide you with samples of the subject handwriting that are normal and natural in nature. If none can be found, request some form of signed identification such as a driver’s license. Make a copy of this identification.
Have available certain writing instruments and papers that will provide the best atmosphere possible for obtaining normal, natural handwriting. Select paper that is as close to the size of the document in question as possible. If the document in question is a form such as a legal document or a credit card receipt, obtain a blank form and make numerous copies for use as the paper on which the handwriting will be taken. Select a series of pens or pencils that are consistent in form to the document in question. For instance, if the writing is in ball point pen, obtain numerous sizes of ball point pens and allow the subject to select that which is most comfortable for him or her. The subject may also wish to use their own ball point pen which would certainly be appropriate and desirable.
Provide a setting for writing that is comparable to the setting of which the document in question was prepared. For instance, if the document is a check that was signed at a teller window, the subject should stand in front of a tall table when preparing the specimens. If the writing is graffiti on a bathroom wall, then a large sheet of butcher paper would be taped to a smooth wall accordingly.
Preliminary Specimens
One drawback to request specimens is disguise. The first few specimens taken should be carefully scrutinized for characteristics of disguise. One technique is to request samples of the subject’s signature and make a brief comparison of these samples to the signature on the identification card. This does not require an in-depth review but rather an overview of the general appearance.
Next, it is recommended that a general handwriting form be completed. A general handwriting form is a document containing numerous names, numbers and words that are to be completed by the subject. Attempts to disguise writing usually results in a nonuniform appearance to the writing - the slant changes or the size of the writing changes.
Verbatim Specimens
Verbatim specimens are those that repeat each questioned entry. This type of specimens allows the forensic document examiner to scrutinize characteristics that interrelate between characters such as relative letter heights, baseline habits and such. It is generally recommended that 15-20 verbatim request specimens be taken.
