Questioned Signatures

Signatures are the result of a lifetime of habitual movement by the writer. They contain unique characteristics that individualise them.

Disputed Wills

When a last will and testament bears testators’ or witness signatures that look odd, unusual or in any way different from the norm, these are known as ‘questioned signatures’.

Handwriting Expert

When it comes to document fraud or potentially fraudulent contracts or wills, attorneys and advocates often require the services of a handwriting expert.

Document Tampering

Document tampering is the act of modifying the physical properties of a document after it has been signed and concluded by the parties.

Handwriting Examination

Most written communication is sent via text or email these days, but handwriting, lends itself to disguise and the concealment of identity and origin.

Dates & Numbers

Nowadays most numerical work is computerised. However, alterations to handwritten dates and numbers can still occur in cases of document fraud.
