I am so happy that I found this. It makes completing so many forms so much easier. Additionally, I've got forms that must be completed that are now no longer fillable through the agency that created them. This will allow me to continue to fill the forms.

For pdfFiller’s FAQs
Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.
Yes, your signature can be your initials. Just make sure that your signature matches what is on your driver's license and any other legal documents to avoid any problems with a bank, etc. You may want to update these if you do change your signature.
Are initials a valid signature?
Besides, one important features of signatures is that it is legally binding and this means that it is enforceable in law courts. Signatures can be created with a person's name or even their initials as long as it has the desired effect on the documents. An initial is just like a representative of your name.
Are initials a legal signature?
Adding initials to the pages of a contract is not a legally binding signature that shows you agree to the terms of the contract. Adding an actual signature (whether ink on paper or electronic signature) is a statement of agreement to the terms and promises of the document / contract.
What is a valid signature?
Usually, a signature is simply someone's name written in a stylized fashion. However, that is not really necessary. As long as it adequately records the intent of the parties involved in a contractual agreement, it's considered a valid signature. Usually this mark is made by a pen, but not necessarily.
How do you sign initials in a contract?
Placing of initials on each page of a document or an agreement means placing of brief identification mark of yourself conveying thereby that the said person has read each of the said pages and further this prevents from adding pages later on after the document has been legally executed.
Can your signature be your nickname?
Signatures necessarily do not have to spell your full name. Signatures are a mark affixed by a person on a document to show his consent or dissent from the writing of the same, provided he puts his hand up and owns that this is his mark.
Does a signature need to be your full name?
Signatures necessarily do not have to spell your full name. If the document or situation asks for your full name as a signature then you will have to put your full name as your signature.
Can a signature be a symbol?
Except in areas where there is a specific law against it, symbols or other marks may be used as a signature. There is no added “security”, however. In situations where the primary purpose of the signature is contractual, e.g. signing a will, marks are more likely to be allowed.
