Legal Question in Wills and Trusts in Texas

There is no requirement that each page of a typewritten Will be signed or initialed. The practice of initialing each page is commonly used as a means of adding some additional security to the document. For the same reason that original Wills should only be stapled a single time, lawyers often have clients initial each page as a way of demonstrating that the testator adopted each page, and that no pages were subsequently introduced in an effort to alter the original Will.

If you want to sign each page lengthwise, it's perfectly fine so long as your signature is not cutting off a part of the language on the page itself.
