For example, after a death, a land transfer or gift deed surfaces that the family never knew of, and the signature looks unlike any known sample
Who This Page Is For
- Heirs discovering suspicious documents after a death
- Persons named in powers of attorney or deeds they never signed
- Estate administrators seeking legal correctness
Common Concerns and Practical Responses
Should I report to police first or sue civilly first?
Gathering complete evidence and verifying facts first ensures the right route — criminal cases need clear grounds, while civil action protects the estate property
I fear the originals will disappear
Notify officials or petition the relevant authority to secure them first — originals are the most important evidence in both tracks
How is a signature examined, and by whom?
Handwriting and document examination by experts in the justice process follows orders of the authority or court; preparing genuine signature samples from several periods is key
What You Can Do Yourself
- Preserve every original untouched — no writing or highlighting
- Collect genuine signature samples of the deceased from various periods
- Inventory the estate and all documents being asserted
- Consult on sequencing — succession, civil, and criminal
Where a Lawyer Can Help
- Assessing facts and the approach to suspected forgery
- Civil proceedings to challenge contracts or transfers relying on the document
- Coordinating court-ordered expert examination
Common Concerns Before Deciding
The estate is not yet settled. Can the forgery issue start now?
Yes, and often necessarily — the document’s status affects the entire distribution
Must I wait for the expert report before reporting?
No — a report can trigger examination, with expert review usually following later
The document is held by the other side. How can I access it?
Legal channels exist to summon documents before officials or the court
Frequently Asked Questions
What offence is forging a signature?
Potentially forgery and use of forged documents under the Penal Code, depending on the document type and use
Is a contract with a forged signature valid?
A contract founded on a signature never given does not bind the person — but this must be proven and enforced properly
Some heirs accept the document. Does that harm my rights?
Other heirs’ consent cannot perfect a forgery, though it complicates the case
